Gravity spiral chute pitch affects the Beneficiation effect, right?

Gravity beneficiation equipment like gravity spiral chute have high utilization rates and good recovery effects in the separation of titanium, iron, manganese, tungsten, tin, gold, quartz sand, zirconium, and other minerals, so they are popular among many users.

What is the pitch of a spiral chute? Dasen Mining will explain it in this issue. What effect does pitch have on the Beneficiation effect?

Pitch is the distance from the top to the bottom of a single blade of a spiral chute. When the distance is greater, the pulp swirl speed is faster, and the processing capacity is greater. With a smaller distance, the pulp flow rate will be slower and the processing capacity will be smaller. Spiral chutes with large screw pitches are generally best suited for rough separation of materials or purification of high-grade minerals. The spiral chute with a small screw pitch is well suited for the separation of low-grade fine-grained minerals, and multiple cycles are required for cleaning and scavenging operations.
