In coal mining industry, the pulverized process plays great role in the whole production line. Based on years' abundant production experience and high technology, we have produced the advanced and high quality pulverized coal Raymond mill machine for your grinding process.
Coal Raymond mill is widely used in ultrafine powder processing of coal, barite, calcite, potassium feldspar, limestone, talc, marble, dolomite and gypsum etc. It can do the super fine powder processing of non-flammable and non-explosive ore, chemical and construction materials, whose Mok's hardness is not more than 9.3 and humidity below 6%. The particle size of the products can be regulated within 40-400. This series of ball mills are divided, according to the material, fineness and productivity, into high-pressure micro powder grinding mill, strong pressure suspension grinder and general Raymond mill.
Features and Advantages
- Three-dimensional structure;
- The screen-passing rate can reach to 99%;
- The transmission is steady and reliable;
- The transmission device of mainframe adopts airtight gear case and zonal wheel;
- Centralized control for the electric system, convenient to operate.
After being grinded, the coal is to be routed to the sorter along the wind belt of the blower and the rough powder will be put back to the grinder for regrinding. The fine powder flows into the product cyclone collector together with airflow and is expelled from the powder output pipe as product. In the grinding chamber, since the coal may contain moisture to some extent, the heat generated during grinding makes the moisture evaporated; since the pipeline joints are not airtight, the external air is sucked in and the circulation air mass increases. In order to enable the grinder to work under negative pressures, the increased airflow is guided to the deduster anew sequentially to the atmosphere after purification.
