In the process of sand and gravel production, the roller sand making machine is a very important equipment. It crushes the sand by the relative movement of two rollers, resulting in a grain size that meets the demand. However, how to ensure the quality of the sand and gravel crushed by the roller sand making machine?
First of all, it is necessary to control the feed size of the sand and gravel. The feed particles are too large or too small, which will affect the crushing effect of the sand making machine. If the feed grain is too large, it may cause the sand making machine to jam or be damaged;If the feed particles are too small, it will lead to low efficiency of the sand making machine. Therefore, it is necessary to control the feeding particle size to obtain a good crushing effect.
Secondly, adjust the roller clearance of the sand making machine. The size of the roller gap directly affects the crushing effect of the sand making machine. If the roller gap is too large, it will lead to too large sand and gravel particles after crushing;If the roller gap is too small, it will cause the crushed sand and gravel particles to be too small. Therefore, it is necessary to adjust the roller clearance according to the actual demand in order to obtain a good crushing effect.
At the same time, it is necessary to keep the roller sand making machine in good condition. Regularly check the degree of wear of the rollers, and if the wear is found to be severe, the rollers should be replaced in time. In addition, the machine should be maintained and maintained regularly to prolong the service life of the machine and ensure the stability and safety in the sand making process.
Thirdly, the moisture content in the sand making process is controlled. Too much moisture can cause the sand to become too wet, affecting its qualityToo little moisture will cause the sand to be too dry, which is prone to dust. Therefore, in the process of sand making, it is necessary to control the moisture content and avoid adverse consequences.
In addition, choose the appropriate crushing method. Different sand and gravel have different crushing methods. When choosing the crushing method, it should be comprehensively considered according to the hardness, toughness, water content and other factors of sand and gravel. At the same time, it is necessary to determine the degree of crushing according to the actual demand to meet the demand for sand and gravel in different fields.
