How to clean a cement mixer?

The article aims to answer the question “How to clean a cement mixer?”. It will also highlight the steps you need to take while cleaning your cement mixer and what cleaners should be used. 

How to clean a cement mixer?

  • Mix in a suitable amount of water into the machine.
  • Add a few scoops of gravel to the mix.
  • Start the mixer and let it run for a few minutes.
  • Cement on the sidewalls of a dam will be scuffed away by moving gravel.
  • To get the gravelly mixture to reach all the way to the edges, tilt the machine.
  • Drain the water and gravel in a suitable location after the cement has been removed.
  • Remove any remaining debris from the machine’s interior and exterior with a pressure washer.
  • Before storing, allow everything to air-dry.
  • Allow the mixer to run for a few minutes before moving on to the next step
  • In the same manner as before, add a couple of liters of water and gravel to the mixing machine.
  • A rubber mallet or small hammer can be used while the drum is spinning to gently tap the outside of the drum. The drum should not be dented. Just to dislodge the larger chunks of dried cement, this is all you need to do here.
  • Allow the water and cement bits to drain after the major portions have been removed.
  • If necessary, use a chisel to remove the last of the huge chunks of cement.
  • After that, don your safety gear.
  • Use your selected cleaning product to coat the equipment you want to clean before attempting to remove the final coating of cement. 
  • Use the chemical in accordance with the directions that come with it, and do so cautiously.
  • Adjust the mixer’s tilt so that the liquid fills the entire barrel.
  • Use water to clean the apparatus. In order to remove the remainder of the cement and flush out any remaining caustic chemicals, a pressure washer is once again essential.
  • Before storing the equipment, allow it to dry.

What chemicals are used to clean a cement mixer?

Hydrochloric acid is traditionally used to dissolve concrete from a cement mixer.

All kinds of issues arise as a result of this. Long-term damage to equipment and major health and safety concerns are among the difficulties that can arise.

For the past few years, this toxic substance has been the only concrete dissolver that works.

Concrete formwork, drums/mixers, trucks, molds, props, and RMC equipment can be cleaned with Consolv, a low-risk chemical solution.

Traditional acids are more harmful.

A simple wash with soap and water is all that is needed if Consolv comes into contact with your skin, unlike hydrochloric acid, which necessitates immediate medical attention.

By using Consolv instead of hydrochloric acid, you reduce the danger of accidents and injuries at work.

As a result, Consolv protects the long-term viability of your costly machinery and equipment.

Any metal that comes into touch with hydrochloric acid emits corrosive gasses that attack the metal.

All of your plant’s machinery, including mixer trucks, will eventually wear down due to rust.

Because of the shorter lifespans and higher maintenance expenses, it is a significant drain on your company’s resources.

We’ve blocked Consolv’s ability to attack metals, making it more corrosive than hydrochloric acid when it comes into contact with metals.

Due to its lack of toxic vapors, it won’t harm other metals and equipment in the workplace.

How often should I clean a cement mixer?

Every time you use a cement mixer, be sure to give it a good cleaning. It is possible for the drum of a mixer to become coated with dry concrete and gravel if you do not maintain it properly. 

Because of this, you should always clean your mixer right after you finish your day’s work. The use of caustic chemicals or chisels to remove hardened concrete will be avoided.

What preparatory steps I need to take to clean a cement mixer?

  • To get your mixer drum spinning, simply turn it on. To begin cleaning the inside of the drum, add some gravel and water. The correct ratios of gravel to water can be found in the mixer’s manual. 
  • Gravel and water should be used in equal amounts to make a mix volume of 3 cubic feet. The water should be added first, followed by the gravel.
  • After roughly two minutes, empty the drum. The gravel can be mixed for a longer period of time if necessary. Turn on the hose and spray the inside of the drum with a high-powered spray nozzle once all of the gravel and water has been removed. 
  • If there is any cement stuck to the drum walls, this should loosen it and allow you to remove it.
  • Remove any clumps of dried cement using a scraper. A firm chisel can be used to scrape out dry cement from the inside of the drum if it won’t budge or has built up due to earlier neglect. 
  • Pneumatic hammers can be used to supplement the power of a hand-held chisel when it’s necessary.
  • Cement that has not broken away can be dislodged with a solution of hydrochloric acid. Apply the solution as directed by the manufacturer while wearing safety gloves and a breathing mask. 
  • A gallon of water needs only a few drops of hydrochloric acid to get the job done. Allow the solution to seep into the concrete before attempting to remove it. Keep cleaning until you’re satisfied with the results.

Conclusion

When cleaning the cement mixer, make sure to do so while the cement is still wet. This is because it takes a lot of chemicals to break down hard concrete. A stiff toilet brush is surprisingly effective when it comes to scrubbing a surface clean.

The outside of a mixer can be coated with Crete-lease. As a result, no cement will be able to adhere to the surface.

Instead of cleaning using chemicals, pressure washers can be used. Even though they can’t remove dried cement, they perform well on wet cement.
