AI Technical Summary
The poor size consistency of lead pellets in the existing lead pellet manufacturing process leads to high energy consumption and reduced quality in the subsequent lead powder manufacturing.
Design a two-stage lead particle screening device, comprising a three-layer screening mechanism: an upper conveyor roller, a middle vibrating screen, and a lower sliding plate. The lead particles are screened by different inclination angles and gaps to form three different particle sizes.
It improves the size consistency of lead particles, reduces energy consumption in subsequent lead powder manufacturing, and improves the quality of lead powder.
