Practical methods and equipment for removing powder from machine-made sand

There will be 10% - 20% stone powder in the production process of machine-made sand, which generally means that the particle size is less than 75 μ M particles. An appropriate amount of stone powder can improve the poor workability of machine-made sand concrete and increase the compressive and flexural strength of concrete, but too high content of stone powder will affect the performance of machine-made sand concrete, so it is necessary to remove the powder of machine-made sand. Today, let's talk about the commonly used powder removal equipment:

Dry powder can be removed with the help of dry sand classifier. It has the advantages of good grading, low fineness modulus, appropriate stone powder content, high output, low water content, less water consumption in the production process, etc, but this method has higher requirements for raw materials, poor sand surface sensory properties, and relatively high equipment costs.
