How Does Raymond Mill Work

Product Description                                                                                                                    

This Stone Powder Making Machine is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 months and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 30 mesh to 325 mesh according to requirements. 

The material of Stone Powder Making Machine is: quartzite ,fluorspar , clay , marble , limestone , dolomite , lime , activated carbon , kaolin , phosphate ore , glass , manganese ore , chrome ore , fireproofing , thermal insulation material , white mud , gypsum , slag , blast , furnace slag , coal , gangue , coke, graphite , sandstone , shale , serpentine , granite ,silica ore , lapis lazuli , pyrophyllite ,medical stone , attapulgite , magnesium ore , iron ore , copper ore , silicious ore , iron oxide red , barium salt , kali salt , alums , bauxite , corundum ,  silicon carbon, potassium feldspar , perlite , lithium , feldspar , tripoli , olivine , magnesite , brucite , alumina , andalusite , kyanite , rose aurora , silver ore , shode , carbon black , illite etc. which are non-inflammable and non-explosive materials with Mohs hardness 7-8 and moisture content below 6% . The final products of the Stone Powder Making Machine can be adjusted freely from 80 mesh to 325 mesh. (the finest can reach 800 mesh )

Working Principles:                                                                                                                                                    

First the materials are crushed by the jaw crusher,then the crushed materials are transferred to a hopper by the elevator, fed uniformly.quantltatively and continuously by the vibration feeder to the grinding chamber of the mainframe for grinding.the ground particles are brought up by the air current of the blower into the classifier for classification.the particles with the required fineness are brought up by the air current through the pipe into a collector for separation and collection,the finished particles are discharged from a pipe outlet,Because of some moisture contained in the materials to be ground, the heat resulting from grinding leads to the vaporized air which changes the airflow volume, Moreover, the outside air inhaled from the narrow gaps of the piping connections can increase the volume of air current. Therefore, it is necessary to adjust the redundant air pipe between the blower and the main unit for keeping the balance of the air current. Then the redundant air is guided into a cloth bag of a dust cleaner to collect the fine powder in the air, Finally, the redundant air is discharged after purification. The Stone Powder Making Machine can meet different requirements.

Features:                                                                                                                                                                     

1. The Stone Powder Making Machine is a vertical structure of strong systematic characteristics, so it occupies a small area. From the crushing of raw material to grinding and packing is an independent production system.

2. Compared with other milling plants,  the Stone Powder Making Machine 's passing ratio achieves 99%, this is what another mill can not reach.

3. The driving system of the mainframe adopts airtight gearing and pulley, drives smoothly and operates reliably.

4. The main parts of the Stone Powder Making Machine are made from cast and steel of high quality. The technics are so subtly that ensure the durability of the whole plant.

5. The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room. Stone Powder Making Machine is also easy maintenance.
