Main technologies and means for cleaning a concrete mixer from mortar

The operation of any equipment depends on constant maintenance. The final stage of operating construction equipment, in particular, a concrete mixer, is mandatory cleaning from remaining construction mixtures and mortar. Neglecting this procedure leads to a decrease in equipment performance and its damage.

A concrete mixer will work smoothly if you clean the surface from the remaining mortar on time. If you leave residues on the inner surface of the unit, the quality of the concrete will subsequently deteriorate due to old pieces getting into the mortar.

Main methods of cleaning a concrete mixer

Experts suggest several cleaning methods:

• cleaning with crushed stone is considered the simplest and fastest way to clean a concrete mixer. From three to five liters of water are poured into the drum of the unit (depending on the mixer volume), then about two buckets of crushed stone are added, and the device is turned on for (10–15) minutes. During cleaning, the tilt angle is adjusted to clean all areas;
• a more delicate cleaning method is using sand. When using this concrete mixer cleaning method, sand is poured into the drum and water is added until a slurry-like state is obtained, the mixer is turned on for 15 minutes, the water is changed, and the process is repeated several times;
• mechanical cleaning methods use a chisel, shovel, or hammer, but you need to work carefully here so as not to damage the surface of the device or its parts. Also, power tools, angle grinders, or drills with metal brushes as attachments are used with this concrete mixer cleaning technology. This is a labor-intensive method that requires the use of protective equipment and caution.

To avoid having to clean the device for a long time after work, it is better to do it immediately, while the mortar has not hardened and is easily washed off with water. We recommend choosing a high-quality concrete mixer and buying it at an affordable price in the "Stroytekhnik" online store.

When starting work with a concrete mixer, you immediately need to decide how and with what to clean the concrete mixer from mortar. During operation and cleaning, it is necessary to monitor the condition of the units and mechanisms of the device, preventing mortar from getting into them.

Chemical agents for cleaning concrete mixers

In addition to mechanical cleaning means using crushed stone, sand, and tools, there are chemical cleaning agents for concrete mixers. In these cases, the following are used:

• hydrochloric acid solutions. A (5–10)% hydrochloric acid solution is poured into the drum, the mixer is turned on, and mixed for several minutes. The used solution is drained, the residue is neutralized with a soda solution, and then washed with water. The difficulty is that the product waste must be disposed of;
• special construction products that dissolve cement. They clean mixers well and do not damage the surface.

The "Stroytekhnik" website offers buyers a large assortment of construction equipment, including concrete mixers.

If you follow the rules for cleaning the concrete mixer, do not allow mixtures to dry out, and monitor its condition, it will serve you for a long time.
