Marble, also known as marble, is a recrystallized limestone, the main ingredient is CaCO3. Limestone softens at high temperatures and pressures, through crystallization, becomes marble when mineral contained changes. The main component of marble is calcium and dolomite, it has a lot of colors, and usually a clear pattern, a lot of mineral particles. Mohs hardness of it is between 2.5 and 5. Marble generally has relatively soft physical properties, which is relative to the terms of the granite.
Marble Grinding Mill Equipment
Marble Grinding Mill Equipment is equipment which produce marble powder from marble. It is not the same with marble grinding machine and marble polishing machine.
There are serious types of Marble Grinding Mill Equipment，it is for making marble powder with size of 0-3000mesh. There are ball mill, hammer mill, Raymond Mill, microfine grinding mill and other grinding mills. Capacity of marble grinding mill equipment is the in the ranges from 0.4T/H to 45T/H.
But how does Marble Grinding Mill Equipment work?
Marble Grinding Mill Equipment mainly consists of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.
After crushed by crushinf plant, the large materials become small ones and are sent to storage hopper by elevator, and then evenly sent to the upper distribution plate of the turn plate by vibrating feeder and sloping feeding pipe. When the grinding mill is at work, the main bearing and each dial are driven by electromotor through reducer, and all the grinding rollers are rolling in the ring channels driving by dial through plunger. The materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers. The high-pressure air blower constantly inhales air, airflow with crushed materials are brought to classifier whose high-speed impeller will screen the airflow: The unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall and exit from the discharging valve at the bottom; A small proportion of the fine powders, with airflow, moves to the dust cleaner. The materials from the above two lots are sent by the conveyor to get finished powders packed. In addition, filtered clean air will be emitted from muffler in the end.
This is Marble Grinding Mill Equipment. Hope it helpful to your understanding of Marble Powder Making Machine.
