coal processing line

Intro

Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.


Crushing Processing Flow

Stage 1. Coal are transported into raw material hopper by truck, and then lifted into storage silo of main machine by bucket elevator.
Stage 2. Coal comes from hopper and feed into main mill uniformly by vibrating feeder, then goes into pipes.
Stage 3. In the grinding process, qualified final product after screening system will go into powder collector by pipes, and then go out from outlet. Unqualified product will go back to main mill and regrind again until it is qualified.
Stage 4. The air flow after purification will go into fan from pipes that up the bag filter, the wind is circular, all other pipes airflow is flow in negative pressure except the pipe from fan to main mill.
