Small foamed concrete machine for sale

Small foamed concrete machine for sale
Foam concrete, also called cellular lightweight concrete is produced by the mixing a lightweight mortar result from water, Portland cement, fine sand including or alone fly ash and preformed stable foam.

The foam is produced with the help of a foam generator by using foaming agent. The air content is typically between 40 to 80 percent of the total volume. The bubbles vary in size from around 0.1 to 1.5 mm in diameter. Foamed concrete differentiates from (a) gas or aerated concrete, where the bubbles are chemically formed through the reaction of aluminium powder with calcium hydro oxide and other alkalies released by cement hydration and (b) air entrained concrete, which has a much lower volume of entrained air is used in concrete for durability. We can also used lightweight small foamed concrete machine with foam pumping machine, can make the walls, make bricks and proof insulation.

Zhengzhou Lead small foamed concrete machine for sale is high quality and easy to operate. Small foamed concrete machine for sale put cement and water into a slurry mixing and then mix them in a certain proportion, press them into transmission pipelines through hydraulic cylinder.

Small foamed concrete machine for sale is mainly used in Cast–in–situ wall, thermal insulation roofing, thermal flooring, external wall thermal insulation, upstanding beam foundation ditches filling, fire protection walls and sound insulation, etc.

Matters needing attention:

1. It is strictly forbidden for stones and other debris to enter the cement slurry mixer.

2. It is strictly forbidden to reach out when the mixer blade is rotating and the main engine is working.

3. When small foamed concrete machine to high-rise buildings, turn off the left switch of the foamer when the pump stops, and turn it on again when pumping again to prevent the foam concrete from entering the foamer under its own weight.

4. The mixing shaft should continue to run when the mixer stops feeding, otherwise the cement slurry in the mixing hopper is easy to settle, and it is easy to get stuck when mixing is started again.

5. The time to stop pumping the foamed concrete should not exceed 30 minutes, otherwise the foamed concrete in the pipeline will easily separate or the bubbles will become larger.  

6. Anti-freezing measures should be taken during construction in cold season. During the construction in the hot season, the oil temperature should be prevented from being too high, and the operation should be stopped when the temperature reaches 80°C.

7. After the high-pressure conveying hose is used for a period of time, the high-pressure conveying hose at the outlet of the FP-25 foam concrete equipment and the end-connected high-pressure conveying hose should be used upside down according to its wear condition to extend its service life.

8. When foam concrete machine works in a dusty environment, the air filter of the air pump should be cleaned or replaced regularly, and the oil (lubricating oil) should be added or replaced in the water pump and the air pump regularly.
