The main component of marble is CaCO3. Marble is extensively used for sculpture, and as a building material. Marble powder is widely used in plastic and rubber filling, especially for the modified marble powder, which has higher filling ability and much easier to store. The recommend grinding mill is HGM ultra fine grinding mill. 

Features and advantages of marble grinding and modifying plant:

1.High fineness, flexible adjustment.

The final fineness of marble grinding mill can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product fineness can reach D97≤5μm

2.High Efficiency

3.Long lifecycle of spare parts.

The ring and roller are forged by special material with high utilization,the lifetime can reach 2-5 years for grinding calcium carbonate.

4.High safety and reliability.

As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.

5.Environment-friendly. There are sound-proof house and muffler to reduce noise, dust cleaner to avoid dust flying outsize, both grinding mill and modifying machine. 

Marble grinding and modiying plant:

Whole grinding line: crusher(hammer or jaw crusher or others) + elevator + hopper + feeder +  main unit grinder + cyclone power collector + pulve bag dust cleaner + blower + muffler + sound-proof house

Whole modifying line: conveying machine + main machine + cycone collector + pulse bag filter + blower and muffler

Stage 1. Marble stone are transported into crusher by truck and crushed into small particle size, and then lifted into storage silo of main machine by bucket elevator.

Stage 2. Marble 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, and then go out from outlet. Unqualified product will go back to main mill and regrind until it get the needed size.

Stage 4. The air flow after purification will go into fan from pipes that up the bag filter

stage 5. The grinded marble powder are conveyed to the conveying machine of modifying machine by screw conveyor or pneumatic conveying system. 

stage 6. Put the agents in the modying machine, the powder and gents are sent to main machine and produce high temperature to get the marble powder modifyed.

stage 7. The modified marble powder be collected by cycone collector and pulse bag filter.
