Maximum output of ball mill is 200MT/hour
SPECIFICATION OF ROD MILL:-
ORE AFTER GRINGING:-
FORTH FLOTATION SECTION:-
From cyclone concentrate mixture goes to blower.
Two liquids are used in blowing these are.
1. Zenithal:-It is used to collect impurity.
2. Pine Oil:-It is used for motion of forth
FORTH FLOTATION SECTION:-
There are four KIRLOSKAR compressors and one is CAMERON compressor.
Compressor house provides compressed air to the mines to drive different pneumatic motors.
This is also makes mines place workable.
COMPRESSOR HOUSE:-
In Mining Machine Repair (MMR) shop, the pneumatic motors are repaired which are used in mines.
