What is the relationship between the efficiency of fine screening and the first stage of grinding?

One of the important factors influencing the efficiency of fine screening is the size of the product entering the fine screen. If the percentage of acceptable particle size in the product is large, the screening efficiency is higher. The key to the fine grain size of the fine screening operation is the first stage of grinding effect. If the first section of the ore is changed due to ore changes and the ore amount changes, or the grain size is rough due to improper operator, when the overflow product enters the fine sieve, not only will the efficiency decrease, but also a "vicious circle" will be produced. The taste of minerals has dropped dramatically. Therefore, careful operation of a grinding operation to ensure the stability of the qualified particle size can not only improve the efficiency of fine screening and screening, but also have obvious benefits for the improvement of concentrate quality.
