Large Out Gyratory Screen Separator for Mica Powder Sieving
Introduction
A client specializing in mica powder production sought a gyratory screen separator to accommodate the diverse particle size requirements for various industrial applications. The primary need was a high-precision, large-capacity screening machine that could handle the fineness variations in mica powder.
Customer Requirements
The fineness of mica powder varies according to different uses and is generally divided into four grades: coarse, medium, fine, and ultra-fine. Mica powder of 8 to 12 mesh is mostly used in roofing materials such as linoleum and is also used for cable wrapping and similar purposes. Mica powder of 40 to 60 mesh is used in the coating of welding rods. Mica powder of 60 to 120 mesh is the basic raw material for the production of mica ceramics. Mica powder of 100 mesh or finer is used as an admixture for paint, a filler for rubber, a covering agent and a lubricant, and a filler for plastics. Ultra-fine mica powder of 200 mesh and below 325 mesh is used as the matrix of titanium mica pearlescent pigments.

Mica Powder Sieving Machine Solutions
The mica powder they produce is used in many industries and has high requirements on particle size, precision, and output. At the same time, it has good sealing during the production process so as not to affect the surrounding production environment. we recommend he choose FYBS-2040-10 layers gyratory sifter. It is designed with 3 layers+3 layers +3 layers structure. We also customized 200 mesh and 325 mesh screens for the client, to meet ultra-fine screening needs.
Results
After testing the machine, capacity reaches 2.5-3 tons per hour. He is very satisfied with the powder sieving machine. The trial operations demonstrated exceptional performance, meeting all the client’s requirements for precision, capacity, and environmental sealing. The client expressed high satisfaction with the equipment’s efficiency and effectiveness in processing mica powder, leading to an immediate order for additional units.
