Coal / Ultrafine Powder Grinding Mill Machine , High Pressure Suspension Mill

coal powder ultrafine powder mill grinding mill from manufactory
Detailed introduction
High Pressure Suspension mill is mainly made up of the mainframe separator blower finished powder cyclone collector bag filter and connecting pipes etc..
 
High Pressure Overhang Roll Mill is applicable to process high-level milling of more than 280 kinds of materials in the areas of non-flammable mine, metallurgy, chemical, construction materials etc, such as barite, limestone, ceramics and slag etc. With the moth’s hardness less than 9.3 and moisture less than 8%. The size of the finished products can be adjusted from 80-425.

According to users’ need the mill can also be equipped with accessory equipments like crusher bucket elevators hopper electromagnetic vibrating feeder and switch box etc. Inside the mainframe the roller subassembly is suspended on the roller suspender through horizontal supporting axis and the roller suspender fixed up with the main shaft and shovel stand. Located outside of the roller bearing house the pressure springs make rollers push down the inside surface of ring through horizontal supporting axis. Shovels installed on the shovel stand and rollers rotate together when the motor drives main shaft through transmission device and the rollers roll appressed the inside surface of ring and rotate at the same time. The separator impellers are driven by motor through transmission device to rotate more higher the speed of separator impeller more fine the powders been separated.
 
Processed Materials: Limestone, calcite, barite, dolomite, potassium feldspar, bentonite, medical stone, rock phosphate, manganese ore, iron ore, quartz, active carbon, carbon black, ceramic, coal, etc..
Applications: Cement, coal , power plant desulfurization, metallurgy, chemical industry, non-metallic mineral, construction material, ceramics.
 
Features
1. Compared with other mills its capacity increases by 10%-20% under the same power condition and compression force of rollers to material improve 800-1200kgf under the force of high-pressure spring.
2. Size of final product can be 0.613mm (30mesh) –0.033mm (425mesh). Some can reach the fineness of 0.013mm (1000 mesh).
3. High Pressure Suspension Mill meets the requirement of national dust-dump standard.
4. The separator can be adjusted very easily.
5. The multi-class seals are adopted to keep the grinding equipment tightly closed.
 
Working Principle
When entering grinding chamber the raw materials are shoveled up by the shovels and grinded between the rollers and ring; the materials after grinding are brought into the separator along with the air from the blower and the qualified fine powder became final products and come into the cyclone powder collector the other unqualified powder fall down to be re-grinded. The circular air returns back to the blower that the above process will be repeated and the remaining air enters the bag filter in order to protect the environment.
 
Technical Data

Advantages:
1. Classifier: Size of final product can be 0.613mm (30mesh) –0.033mm (425mesh). Some can reach the fineness of 0.013mm (1000 mesh).
2. Grinding device: The multi-class seals are adopted to keep the grinding equipment tightly closed.
3. Spacer protective measures: Mainframe is under protection, easy to be replaced, maintenance cost is reduced.
4. Spring strengthens grinding force: Compared with other mills, its capacity increases by 10%-20% under the same powder condition. compression force of rollers to material improve 800-1200kgf under the force of high-pressure spring.
5. Blower: Enhancing fan configuration and frequency conversion speed can be based on features of different materials, fineness, production requirements so as to efficiently adjust the air volum, achieve the best running state and reduce the energy consumption.
6. Pulse dust collector: Dust removal effect reaches the national powder emission standards; According to customers' actual demand, pulse bag filter can also be used, thus achieving rapidly automatic dust removal, and dust removal efficiency is higher.
