Introduction

Description

The color of mica changes based on chemical component and darkens with the increased content of Fe. Mica has the features of insulation, thermostability, shininess, stable physical and chemical property, good insulation, elasticity, and toughness. The most used in the industry is white mica, followed by gold mica. It is widely used in the industries such as construction and firefighting sector, extinguishant, electrodes, plastic, electrical insulation, papermaking, rubber, asphalt paper, and pearlescent pigment. Before actual application in the production, the exploited mica shall be crushed into small aggregates. The configuration of 1000-1200t/h mica production line is detailed as follows.

Process

After being blasted from the mountain, the mica stone less than 1200mm is sent into the vibrating feeder by dumper and then evenly fed into heavy hammer crusher for primary crushing. The large blocks coming out of the heavy hammer crusher will be conveyed to the next crusher for secondary crushing and shaping. After being screened and graded by the circular vibrating screen, the block materials with unqualified size will be returned to the secondary crusher for re-crushing while the finished materials are conveyed to the finished product area.
With the compressive strength of about 150Mpa, mica is a kind of soft rock; therefore, it is an economical and reasonable technique to adopt the two heavy hammer crushers to form a closed circuit for crushing twice in the calcite production line.
