Effect of material properties on sand production

1, material hardness

The main factor affecting the ease of ore crushing in the production process is the hardness of the ore itself.

The mechanical properties of most ore materials are unevenly distributed. The materials with large block size and many texture gaps have poor mechanical strength and are easy to be broken. The smaller the particle size, the less the internal texture gap, the higher the mechanical strength and the less likely to break. The greater the hardness of the ore, the greater the density, the greater the difficulty of breaking, the lower the efficiency, and the more serious the wear on the equipment.

2. Feeding granularity and reasonable feeding amount

Each model defines the maximum particle size of the feed. If it is too large, the blockage will cause the device to lose its crushing function, and the excessive amount of fine powder contained in the material will also affect the sand production. For materials with a high content of fine powder, sieve it in advance and screen it out to avoid affecting the normal operation of the equipment.

While ensuring the output, a suitable feeding amount is beneficial to increase the life of the wearing parts. When the feed amount reaches 70%~90% of the impeller full load, the sand production reaches a peak. If the feeding amount is too small, not only the output of the equipment is reduced, but also the wear amount of the crushing chamber liner and the like is increased, and the replacement period of the fitting is shortened.

3, material humidity

That is, when the moisture contained in the material is large, the material is easy to adhere in the impact sand making machine, and it is easy to cause clogging during the feeding process, which causes the sand discharging ability to decrease. If the humidity of the selected material is too large, you can use sunshine or air drying to reduce the percentage of moisture in the material.

4, material viscosity

The greater the viscosity of the material, the easier it is to adhere. The material with high viscosity will adhere to the inner wall of the flow channel cavity in the impeller, and even block the flow channel. If it cannot be cleaned in time, it will affect the working efficiency of the crusher, and may affect normal work in severe cases. Therefore, when selecting materials, you should choose a low viscosity.
