Impact drill as a mixer

Impact drill. Functions, modes of operation, applications

In this article, we will get acquainted with such an electric tool as an impact drill. Let’s find out its main purpose, modes of operation and ways of application in carrying out various operations on repair of the apartment. Also, I am sure that after reading this article, you will be firmly convinced that this wonderful tool is almost one of the main and must be present in your arsenal.

All those who are just starting to take their first steps in comprehending the basics of repair usually gather their experience with simple jobs, such as hammering a nail, screwing a screw, preparing wallpaper glue, drilling a hole in the wall, etc. п. Of course, many works can be done manually, doing without power tools. However, doing repairs, we must remember about the convenience and the time spent. You can, for example, a couple of screws tighten by hand with a screwdriver and hang a shelf. Another thing is if you need to fix a sheet of drywall the size of half a room to the guides, where you need to screw in half a hundred self-tapping screws. You can’t screw them in with your hands, you’ll get tired! And here, then begin to think how it would be faster but at a lower cost to make.

Here you can say, but why are we talking about an impact drill?? After all, you can use an ordinary drill with an attachment to screw in self-tapping screws, and even easier. get an electric screwdriver. That is correct. But for beginners in the repair to buy a few expensive power tools at once can be expensive. In this article I want to show how one tool can be turned into several and get along just fine with it at first.

How to determine the right variant

To date, manufacturers offer three versions of the mixer:

A mixer drill is a hammerless low-speed drill with a metal gearbox, which has an unusual design. Low (powerful and slow) speed allows you to use it regularly as a construction mixer. The power of such a tool ranges from 500 to 2000 watts, depending on the reliability and manufacturer. The device features a non-standard design for a drill, there are two handy handles for a secure grip and a large chuck up to 16 mm.

Generally speaking, the mixer drill is the choice for the home; it can handle light to medium consistency mortars. Models with a capacity from 1 kW can also be used in construction for mixing viscous foundation mixtures. In addition, low-speed drills are excellent not only for normal drill work, but also for drilling large holes. For example, when it is necessary to drill a wooden log house they are used.

Two-handed versions of the mixers are divided into versions with one whisk or with two whiskers. The difference between them is obvious: the two whiskers quickly and efficiently mix any mixture, even very viscous. The power of such models starts from 1 kW, if the indicator is less. you should not buy the tool.

Construction mixers with two handles are equipped with a large gearbox and are designed for all types of mortars: from the lightest to cement mortars. If there is no specific purpose of use or the area of tasks is not clear. this is the best choice.

The first thing you should do before buying. to assess the scale of future work. There’s no point in overpaying for unused potential or a second whisk if the tool is needed for light, one-time work. This rule applies and vice versa, a weak mixer drill will not always cope with the pouring of the foundation.

How to mix a mortar?

Regardless of the choice of tool, the construction mixture should be mixed as thin as possible, to a thicker consistency. In other words, to add cement and sand in a single bag to achieve the required thickness, you need to add it in two, or better, three steps. If you try to make a very dense mortar at once, it will be quite difficult and will have a negative effect on the motor and the internal mechanism of the power tool.

It is also important to choose the right nozzle. Three types can be found in the range of construction stores:

Screw mixers are used for obtaining liquid mixtures, and cross-shaped ones for thicker mixtures. Cruciform nozzles with right angle spiral work well with mortar, which includes gravel or gravel. The nozzle evenly distributes the components throughout the entire volume, preventing them from falling to the bottom. Combi nozzles are universal and can be used in mixing any type of mortar.

To minimize the load on the drill, it is better to give preference to a mixer with the smallest possible size of the working part. The wider the blades of the mixer, the more power is required to rotate them under mortar load. You can buy a bigger mixer for the peorator than you can for the drill. Because this tool can work under a heavy load and develops great power.

Construction mixer. how to make a quality mixture?

In all of the above methods, it is the peorator that tries to replace the mixer when mixing. How much is justified? Is the peorator is able to perform a function that is not peculiar to its basic application? We will try to answer all these questions in this article.

modern rotary hammers are known to work in at least two modes: drilling and drilling with a hammer. It is also known that an adapter (additional chuck) for drills is inserted into a standard SDS chuck for drilling. Therefore, it is not very difficult to insert the mixing nozzle from the mixer. Next. Quite a few gears have a mechanical gearbox built in, which allows for different speeds. Then, obviously, the whole salt of the new function for the pen is concentrated in the drive of the pen. All hand torches, as well as mixers, are equipped with a universal collector motor, the shaft speed of which is controlled by increasing or decreasing the supply voltage. The question then comes down to the characteristics of these motors, the main ones being the maximum motor shaft speed, the power on the shaft and the torque on the shaft. Let’s see how the gerotor works separately for two types of kneading agents: low viscosity and high viscosity. A low torque and different shaft speeds are required for stirring a low-viscosity mortar. Single-speed gears are known to be controlled by the force of the trigger, usually in the handle of the power tool. By varying the trigger pressure we change the shaft (spindle) speed smoothly: a low pressure changes the speed and a high pressure changes the speed up to the maximum.

The problem is that the speed lock is usually triggered only when the trigger is fully depressed, that is, at maximum engine speeds. This is very inconvenient when stirring. evidently, the solution is to run such tool with step-down transformer (LATR may be used), which power should exceed or be equal to power input of the mixer. In this case, acting as an agitator has a good chance of success.

In addition, there are nowadays models of rotors with adjustable speed control that can also be used as agitators. You should always remember that the lower the voltage of the motor supply, the lower the efficiency of such a motor.

It’s more difficult with highly viscous media. They usually require low speed and high torque to mix them. If the speed can be adjusted by connecting a step-down transformer to the torch (as in the above case of low-viscosity media), this will not work with the torque, because when the voltage supplied by the transformer is reduced, the torque on the shaft falls with the shaft speed (smooth characteristic).

It follows that operation via transformer (at low voltages) is advantageous only when the torque of the torch exceeds the torque required to mix the medium, which is not often the case. Otherwise the motor needs additional cooling (especially at low shaft speeds, where the fan built into the motor does not create more or less normal air flow to the collector of such a motor), because otherwise the overheat protection is triggered (motor temperature sensor will cut off the power to the torch).

In addition to additional cooling some other methods can be used: reducing the diameter of the working part of the nozzle (This is one of the most effective ways to reduce the required torque!), reducing the diameter of the tank and/or the height of the stirred layer. The ideal solution is the multi-speed accelerator. Viscous solutions can be handled with one at low shaft speeds and slightly viscous solutions at higher speeds.

Let’s consider the performance of the pen as applied to high-speed mixing for obtaining frothy solutions or fine suspensions and/or emulsions. The standard maximum operating speed of the accelerator is about 1000 to 2000 rpm, which is adequate for most mixing applications./min., which is sufficient for most stirring operations at normal speed.

However, it is not possible to obtain higher rotations with these gears without using external mechanical gears, because the motor operation is limited by the supply voltage (220 V). For torches with integral gearboxes, maximum shaft speed will be at the highest gear of the gearbox and at maximum supply voltage.

Thus, a peorator can be used as a mixer. For low viscosity media an additional step-down transformer may be necessary, although not compulsory. High viscosity media may require additional motor cooling or more frequent pauses during stirring required to cool the motor. For high-speed (very fast) mixing that exceeds the maximum speed of the mixer shaft, an additional external mechanical gearbox may be required

Mixing concrete with an electric mixer: Features and operating technique

Anyone who builds a house by himself, without hired workers, wants to simplify his task. For example, using a concrete mixer to mix concrete. A quality concrete mixer is not cheap. A lot of people would say it’s worth the price in a construction season. But I want to save money and not to break my back, mixing concrete with a shovel. That’s when the idea. to use an electric mixer to batch the mortar of sand, cement and gravel.

I saw a YouTube video. a man, alone, using two-spindle mixer, kneaded concrete and poured a strip foundation in two days. I thought maybe this is an advertisement for a tool? The builder says that it is more convenient to mix with a mixer than with a concrete mixer. The question for me is relevant. I used a concrete mixer. It’s hard to do it alone. You have to lift the buckets. Load the bag. I rented a concrete mixer. No place to store his own. And you can use a mixer to mix concrete right on the pouring site. It doesn’t weigh much. Podskite. is it realistic if you knead small amounts? Maybe someone has already used a mixer? The tool will not break?

I think that tools should be used strictly for their intended purpose. You need a mixer to mix plaster and adhesive mixes, and a concrete mixer to mix concrete. The weak point of the mixer is the nozzles. The whisk, on heavy concrete with gravel, the blades can come off, or it will bend.

Compare the price of a normal mixer and a concrete mixer. There’s not much difference. I think health is more important! Using a concrete mixer, you can work with two people. One carries sand and gravel, the second monitors the mix. You work alone with a mixer. On this, oh what forces are needed. You’ll get tired quickly. My mixer is 10 years old, and it paid for itself long ago.

Now let’s hear the views of those members of FORUMHOUSE, who actually mix concrete mixer.

I poured a strip foundation for a fence with a mixer. The length of the belt is 25 meters. The cross-section is 200×300 mm. I also concreted a lintel of 5 m for the gate and the wicket. From my experience, I say, more tired, not from working with a mixer, and from throwing sand, cement and gravel, and pulling concrete. But you have to throw ingredients into the concrete mixer, too. It still needs to be washed later, and the mixer spun in the water and went home. I would not dare to pour a house foundation with a mixer, of course, but, for small volumes, it is a good option.

  • At first he was dry mixing sand and cement.
  • Then you add water. The consistency of the mixture, like sour cream.
  • Then I threw in three buckets of gravel. I stirred the mixture. Then I added another one.5 buckets of gravel.

I mixed with a twin-spindle mixer concrete in a cast iron tub. Two spindles are better than one. The torque is dampened and in case of a wedge, it won’t wind up on the tool. I poured the cement, sand and gravel fraction 5-20. I was mixing for ten minutes and 200 liters of mix is ready. I won’t say it was easy, but it wasn’t hard. Crushed stone between augers didn’t jam. The tool didn’t break.

Short. I listened to everyone, and also decided to mix the concrete with a mixer. Reporting back to. Knead about 1.5 cubic meters of concrete for a pile foundation. It’s stiff. Proportions: 1 part cement, 3 parts sand, 4 parts crushed stone and 0.75 l of water. I mixed in a trough for 100 liters. I did 5-7 mixes a day. Couldn’t do it anymore. My arms, especially my hands, get very tired. I can’t say that I’m weak, but the eversion stress on the joints is considerable. Crushed stone fraction 5-20 is not stuck between the corbels. The tool also held out. The verdict: the method is suitable for small amounts of onetime work.

I wonder if you can pour using a mixer volumes of larger? The construction experience of FORUMHOUSE users says: “Yes”.

I and my assistants poured a mixer 4 cubic meters of concrete. There were four people working. two men and two women. The women poured cement and enriched sand-gravel mixture into buckets. One man was kneading. The second drags the buckets, and then the two of us pour the mixture into the formwork. Mixing proportions: 1 bucket of cement, 1 bucket of sand, 3 buckets of OGPS, 0.7 buckets of water. All in all we made 115 mixes with a bite to eat. It was raining. The old trough is leaky, too. Repaired it. In the end: started at 10 am, finished at eleven o’clock in the evening. Then, in the morning, we also did some kneading. Your back gets tired, but if you get used to holding the mixer without tilting it, with your feet wide apart, you won’t get tired. If we had started mixing at 7 am, if it had not rained and the bucket had not rusted, I think we would have made it by 6 pm. The mixer kneads the mixture quickly. The main fatigue is from dragging the buckets with the OPPS over the formwork and raising the bucket to the level of the formwork to pour the concrete.

Veter753 tips for working with a mixer when mixing concrete:

  • First load water, cement and sand.
  • Knead the mixture until it is sour creamy.
  • Add 2 buckets of OPGS.
  • Knead mixture until gray and uniform in color.
  • Add another bucket of OGPS.
  • Once again, evenly distribute the saw.

Two of us poured 17 cubic meters of concrete with a mixer in 4 days. Monolithili slab. The concrete was being mixed in a tub. We put it on the reinforcement inside the formwork and turn it upside down after each mix. Tired, of course, but you’d be tired with a concrete mixer, too. I liked working with a mixer. Stirs quickly. Hands don’t twist, my back doesn’t hurt, even though we were mixing with a single spindle tool. Getting more tired from carrying sand, cement, and crushed stone.

Recommended nozzles

We recommend our mixer tool 120x600mm SDS from STARTUL and 120x600mm M14 whisk from GEPARD.

The 120x600mm SDS STARTUL whisk is a right-handed spiral and is suitable for drills and rotary tools with SDL-Plus connector. Recommended battering speed 600 rpm, it is used for all kinds of heavy and viscous mixtures (plasters, fillers, resins, concretes, etc.).

Whisk 120×600 mm M14 GEPARD has M14 shank with 105/120 mm height and diameter of the basket. Configured as a right-handed spiral and capable of battering at an optimal speed of 600 rpm.

In conclusion, we recommend choosing a mixer, pay special attention to the type of shank, because an error will lead to the fact that the whisk simply will not stand on the peorator or drill.

Tool varieties

Electric drills are considered the most popular tools, because they can be used for various purposes. Specialists divide them into two main groups:

The first option is used briefly during repairs or one-time interior design work: fixing shelves and baguettes or equipping the kitchen with hinged cabinets. The second one is for daily, continuous use on construction sites.

The maximum power of professional tools. 1550 watts, for domestic use are popular with drills with power up to 600 watts. Drills up to 300 watts belong to the light tool and do not have an additional second handle, this distinguishes them from the two-speed household impact drill. They are used in hard-to-reach places, where more powerful tools couldn’t reach because of their size.

Cordless impact drill has low weight, maximum torque for soft metals up to 24 N. m, for hard holes up to 55 N. m, can drill holes up to 13 mm in diameter. Such a self-contained tool belongs to the class of two-speed impact drills.

All models of modern impact drills have adjustable speeds, so they are unified: they can drill holes at high speeds or tighten screws and screws at the lowest rotation of the spindle. Many are equipped with a reverse for easy removal of the drill from the hole after drilling, unscrewing screws and screws in electric screwdriver mode.

Many people wonder why they need the long metal part sticking out of the special holder on the removable extra handle? This is the drill depth control. They can be used to accurately measure the size of the hole to be drilled, and act as an improvised stop during the drilling process.

Type of mortar

All construction mixtures are divided into several classes: lean, normal and fat. They differ from one another in the amount of base material used. The most viscous and complex in preparation are considered to be fat mixtures. To cope with the mixing of these compositions conventional types of drills can not in principle. That is why it is better to immediately buy low-speed types of devices for such cases. The presented variations of the devices differ in a number of properties. For example, they have a fairly high power. According to this indicator, the models are often several times better than their analogues. Also devices differ in a small number of revolutions of the tool. The result is an increased torque. This makes it possible to mix the most viscous mixtures and achieve a more complete interpenetration of the components.
