How you can Strengthen the Efficiency of Spiral Classifier
Blog Submitted by yoyocrusher on 12/21/2017 at 2:45 AM Report Blog

Materials just after entering to the Ore Milling Equipment through the inlet and being scattered over the spreading plate, fall in to the deciding on airflow. The rotation velocity of the screw not merely influences the overflow particle size, but additionally impacts the transmission capacity of grit. The fine powder is expelled in the central pipe, and collected by dust collector. The faster the velocity, the greater the yield of sand return meter. But simply because the stirring result within the ore pulp increases, the amount of coarse particles mixed during the overflow grows. The separating airflow mostly originates from dusty gas, tangent to the main and secondary airflow inlet as well as the fixed guide vane, and then enters in to the powder choosing area.

Therefore, when picking screw rotational velocity, it really is important to know the necessities on overflow fineness and sand return yield rate. The secondary ore grinding or fine grinding procedure needs finer overflow products, so the rotational velocity of the screw must slow down a little. The cage rotor composed of coarse and vertical blades and horizontal blades, maintains a particular pressure variation within and outside in the height of powder picking out area by way of rotating.

Materials through the top rated towards the bottom, the coarse powder is separated by the principal and secondary airflow, providing a chance for every particles to become chosen repeatedly. Then resources will probably be separated by the third airflow on the bottom, and discharged through the bottom from the machine.

Spiral classifier is an important adjusting factor in the operation of ore pulp density, that is utilized to control the classifying overflow fineness. Normally speaking, the reduce the pulp density is, the finer the overflow particle will grow to be; Otherwise the overflow particle will get coarser. Since in thick pulp, the high viscosity on the pulp will hinder particles from settling, primary on the sedimentation velocity slowed down, which makes the overflow granularity on the spiral classifier coarsens.
