How to put the mixer in the drill

mixer, drill

If not a lot of work, and the work is not permanent, and periodic, you can use a drill to mix the cement mortar, the drill needs such a whisk. But you should clearly understand that when kneading mortar the drill chuck will be affected by lateral loads, the drill, unlike the construction mixer, is not designed for it.

You can do it this way: Insert a metal rod into the chuck hole (a drill shank of suitable diameter will do) and use a slotted screwdriver “on the lever” to tighten the chuck. To be more reliable, we move it to the next hole and repeat the action. In the same way you can open the chuck.

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 to the composition of one bag to achieve the desired consistency should be added in two, or better, three steps. If you try to make a very thick mortar at once, it will be quite difficult and will have a negative effect on the motor and the inner workings of the power tool.

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

Screw mixers are used for making liquid mixtures, and cross mixers for thicker mixtures. Cruciform nozzles with a right-hand spiral work well with mortar, which includes gravel or gravel. The nozzle distributes the components evenly throughout the entire volume, preventing them from falling to the bottom. Combi nozzles are a versatile solution and can be used in mixing any construction mixture.

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 mixer blades, the more power is needed for their rotation under a mortar load. A more impressive mixer can be purchased with a peorator than with a drill. Because this tool can work under a heavy load and develop great power.

How a chuck in a drill is designed

Household drills and rotary tools are mainly made with jaw chucks. They are a cylindrical body containing cone-shaped cams. On the surface of the chuck moves an adjusting ring, with its rotation the cams approach each other and move away, all depending on the direction of movement.

The foot is inserted in the space between the jaws. They snap together and firmly clamp the drill in the chuck. With the help of the cam type, it is possible to fix elements of different diameters in the chuck. The diameter range of drills for household drills with a cam chuck is 8 mm-10 mm and 1.5 mm-13 mm.

Chuck jaws can be standard jaws, i.e. key-operated jaws, toothed jaws or quick-action jaws. A conventional chuck clamps with a wrench, which sets the gear drive in the form of prongs and an adjusting ring.

The quick-action chuck has a different design. the cams are driven by a knurled metal sleeve. The sleeve rotates by hand.

The quick-clamping chuck can have locking elements that will limit the clamping force. Then the drill bit can be locked in the tool by a characteristic click or a locking button.

There are also single sleeve and double sleeve chucks. In a single-feed chuck, the sleeve rotates in relation to the body of the drill, and it is only necessary to lock it. With two rings (sleeves) the core moves in relation to the second ring, and it can move relative to the drill itself, so you need to lock the other sleeve by screwing the core by hand.

Impact mechanism

It would seem that this function is not necessary for a drill used as a mixer. In fact, it’s far from it. The point is that often the mortar hardens on the bottom and walls of the tank. You just can’t get it off with a regular drill. This is where the purchase of a percussion tool is recommended. The reciprocating motion of the tool will create an additional impetus, resulting in a significantly accelerated process of cleaning the container from the cured mixture.

During performance of repair works it is very often required to use the most various manual, automatic or semi-automatic operations: chiselling, drilling, polishing, grinding, cutting, welding, etc. д. It is known that for each repair operation there is a specialized tool.

It is not always necessary to perform these operations equally often: sometimes it happens that a particular repair operation is relatively rare, or only once at all. What to do then? Running out and buying the right construction tool for a one-time use? Borrow from neighbors, acquaintances or friends “for a couple of days”? Of course, there is a desire to use a tool that is already in the work to replace the missing tool. The most common tool used in repair and construction work is the peorator. Practically everyone, who at least once in his life has faced with the repair, possesses such electric tool. On the other hand, one of the most seldom used today tools is a construction mixer designed for mixing of various construction and repair mortars. The reason for its infrequent use in repair work is the usually small amount of mortar (varnish, glue, etc.) to be stirred at a time. д.the specificity of the process (uniformity, very fast or very slow rotational speed of the shaft, their combination, etc.), which can be achieved without mechanization: stirring by hand. Nevertheless, there are cases when it is necessary to use electromechanical mixing: very viscous medium, large volume, harmful medium, large mass of one mix, specificity of the process (uniformity, very fast or very slow rotational speed of the shaft, their combination), short terms, requiring high productivity, etc. д. In all of the above methods, it is the mixer that attempts to replace the mixer with a peorator during mixing. How justified is it?? Is the peorator capable of performing a function which is not typical of its basic application?? Let’s try to answer all these questions in this article. As you know, modern rotary drilling machines can be operated in at least two modes: drilling and hammering. It is also known that in order to drill in a standard SDS chuck an adapter (additional chuck) for drills is inserted. It is therefore not very difficult to insert the mixer nozzle from the mixer. Next. Quite a lot of gears have a built-in mechanical gearbox, which allows you to work at different speeds. Then, obviously, the whole salt of performing a new function for the peorator is concentrated in its actuator. All hand torches, as well as mixers, are equipped with universal collector motor, the shaft speed of which is controlled by reducing or increasing the supply voltage. The question then comes down to the characteristics of these motors, the main ones being the maximum rpm of the motor shaft, the power on the shaft and the torque on the shaft. Let’s consider the performance of the torque ratchet separately for two kinds of stirred media: low viscosity and high viscosity. Stirring of low-viscosity mortar requires small torque and different speed of shaft revolutions. It is known that single-speed rotarys are controlled by the force of the trigger, usually in the handle of the power tool. Applying different force on trigger we smoothly change shaft (spindle) revolution: when pushed weakly, we get low revolution and when pushed strongly, we get high revolution up to maximal one. The problem is that the speed detector usually operates only when the trigger is pulled fully, i.e. at maximum engine speed. This is very inconvenient when stirring. Obviously, the solution is to run such tool through step-down transformer (you can use LATR), which power should exceed or be equal to power consumption of the torch. In this case, the use of the accelerator as an agitator has a good chance of success. In addition, there are nowadays variable speed control gears which can also be used as agitators. It must always be remembered that the lower the supply voltage of a transformer motor, the lower the efficiency of such a motor. This is not the case with highly viscous media. Low speeds and high torque are usually required to mix them. If the speed can be adjusted by connecting a step-down transformer to the mixer (as in the above mentioned case of low-viscosity media), it cannot be done with the torque, because when you decrease the voltage supplied by the transformer, the torque on the shaft goes down with the shaft speed (smooth characteristic). It follows that it is advantageous to work through transformer (at low voltages) only when torque of peorator exceeds required torque for stirring medium, and this does not occur so often. Otherwise you need extra cooling (especially at low RPM when the fan built into the motor doesn’t create more or less normal airflow to the collector of such motor), because otherwise the overheat protection will trip (motor temperature sensor will cut off 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 vessel and/or the height of the stirred layer. The ideal solution is the multi-speed accelerator. With it, one can work with viscous solutions at low RPM on the first speed and with low-viscosity solutions at high RPM on the second speed. Let’s consider the performance of the torch as applied to high-speed mixing for obtaining frothy solutions or fine suspensions and/or emulsions. Typical maximum rotor speed is approximately 1000 to 2000 rpm./min., which is sufficient for most stirring operations in normal mode. However, it is not possible to achieve higher rotational speeds with such geared motors without using external mechanical gears, because the motor operation is limited by the supply voltage (220 V). For torches with integrated gearbox, the maximum shaft speed will be equal to the highest gear of the gearbox and at the maximum supply voltage. Therefore, it is quite possible to use the torch as a mixer. For low viscosity media an additional step-down transformer may be necessary, although not required. For very viscous media, it may be necessary to cool the motor additionally or to allow the motor to cool for longer than usual pauses during the mixing process. At high-speed (very fast) mixing, exceeding the maximum speed of the shaft of the hedge trimmer, you may need an additional external mechanical gear

Can mortar be stirred with an ordinary drill or a rotary table??

Preparation of cement mortar is an essential part of construction works. Kneading it in large quantities is difficult enough, but also requires a lot of time and effort. A torch or a powerful electric drill is good for this. You should not hurry to rent, much less buy a concrete mixer or construction mixer. In most cases it is absolutely unnecessary.

Homemade mixer

An electric mixer with their own hands to make pretty easy. To do this, you can use as a driver an ordinary household electric drill or peorator. For a drill fit the device with a shank in the form of an ordinary hex or HEX. Both are easy to fix in the cam chuck of the drill. The main thing is that the size of the hexagon (standard: 8, 10 and 12 mm) must correspond to the maximum size that can be inserted into the chuck of the drill.

Attention! Only low-speed drills, or devices with variable speed can be used for stirring mortars.

If as a drive you use peoratora (of course, in hammerless mode), it is necessary to buy attachments with a shank designed for mounting in the SDS-plus chuck.

However, please note that motors and gears, as in an electric drill, and the peoratorov (even powerful) are designed only for the longitudinal load. Therefore, self-made mixer on their basis is quite suitable for mixing non-heavy solutions and in small volumes. When stirring mortars, the drive is subjected to considerable radial and horizontal loads, which can lead to overheating and failure of the electric motor. Therefore, the mixer for concrete with their own hands out of a drill or a peorator is better not do. Although their use is quite acceptable when stirring paints, light putties and other lighter solutions.

Mixer on the peorator

How much of this is justified?? Is the torch capable of performing a function other than its primary application?? Let’s try to answer all these questions in this article.As you know, modern rotary tools can operate in at least two modes of operation: drilling and drilling with a hammer. It is also known that in order to carry out drilling, an adapter (extra chuck) for drills is inserted into the standard SDS chuck.

Then the question comes down to the characteristics of these motors, the main ones being the maximum rpm of the motor shaft, the power on the shaft and the torque on the shaft.Let’s consider how the gator works separately for two kinds of stirred media: low-viscosity and high-viscosity Small torque and different speed of shaft revolutions are required for stirring slack mortar. It is known that single-speed rotators are controlled by the force of the trigger, usually located in the handle of the power tool. We use different trigger pressures, we can change the shaft (spindle) speed steplessly: a weak press moves the shaft to a lower speed and a strong press moves it to a higher speed, up to the maximum.The problem is that the speed lock is usually triggered only when the trigger is fully pulled, i.e. at maximum engine rpm. This is very inconvenient when stirring. The way out is obviously to run such a tool with step-down transformer (you can use LATP), which power should be more or equal to power consumption of the torque-limiter. In this case, the work of the peorator as an agitator has all chances to succeed.In addition, there are nowadays models with variable speed control that can also be used as agitators. It should always be remembered that the lower the supply voltage of the gerotor motor, the lower the efficiency of such a motor.It is more complicated with highly viscous media. They generally require low speed and high torque for mixing. If the speed can be adjusted by connecting a step-down transformer to the mixer (as in the case of low-viscosity media described above), this does 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 it is advantageous to work through a transformer (at low voltages) only when the torque of the peorator exceeds the required torque to mix the medium, and this does not occur very often. Otherwise, you will need 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 will be triggered (the motor temperature sensor will cut off the power to the torch).Besides the 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)!), a reduction in the tank diameter and/or in the height of the mixing bed. The ideal solution is the multi-speeds. This makes it possible to work with viscous solutions at first speed at low shaft speed and with low-viscous solutions at high speed at second speed.Let’s consider the operation of the pen as applied to high-speed mixing for obtaining frothy solutions or fine suspensions and/or emulsions. Standard maximum gearing will be approx. 1000 2000 rpm./min., which is sufficient for most normal stirring operations.However, it is not possible to obtain higher speeds with these peorators without using external mechanical gears, because the motor operation is limited to the supply voltage (220V). For motors with integrated gears, maximum shaft speed is equal to the highest gear of the gearbox and at maximum supply voltage.Thus, the peorator may well be used as a mixer. For low-viscosity media an additional step-down transformer may be required, although this is not necessary. For high viscosity media it may be necessary to give the motor additional cooling or to allow the motor to cool in shorter than normal intervals. For high speed (very fast) stirring that exceeds the maximum speed of the rotor shaft an additional external mechanical gearbox may be necessary

How to remove the drill bit from the chuck?

Before pulling out the drill, check that the core drill is unplugged from the powerpack and that you do not accidentally press the start button on the cordless tool. Do not pull out the drill bit until the chuck has stopped turning.

Warning! Never brake the chuck with your hands, otherwise you could injure yourself.

If the drill is equipped with a quick-action chuck, the steps for extracting the drill bit are as follows:

  • Remove your finger from the starter button.
  • Wait for the chuck to come to a complete stop.
  • Hold the chuck by its base with one hand. Turn it counterclockwise with your other hand.
  • When the chuck jaws have separated sufficiently, remove the drill bit.
  • Carefully place the drill on the table, making sure it does not roll away.

If the drill is equipped with a keyed chuck, do the following

  • Turn the drill off and wait for the chuck to stop.
  • Insert the wrench in the hole in the chuck.
  • Turn the key counterclockwise so that it moves the cartridge.
  • Unscrew the chuck by hand so the jaws release the drill.
  • Take the drill out of the chuck.
  • Place the key in the hole on the wire so it does not get lost.
