According to many years of raymond mill's technology improvement and practice , the structure of raymond mill is getting perfect by small occupation area,low investment,low consumption, environment friendly, and more efficient than the traditional raymond mill.
Raymond mill also called Raymond grinder or Raymond grinding mill is applied widely in mining, construction, chemical industry and metallurgy etc. After many years of practice and improvement by manufacturer SBM, the structure of Raymond mill is getting perfect by low consumption, low investment, environment friendly, small occupation area, and more efficient than the traditional industrial grinding mill.
Raymond Mill Application
Raymond mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. Raymond mill can produce powder from more than 280 kinds of non-flammable and non-explosive mineral materials with Mohs hardness below 7 and humidity below 6%, such as barite, limestone, quartz, calcite, granite, porcelain clay, basalt, gypsum etc. The final size is between 613micron and 440 micron (0.613mm—0.044mm). Raymond mill grinding material requirements are non-flammable and non-explosive stuff which has the Moh’s hardness below 7, humidity less than 6%.
Raymond Mill Working Principle
Load the stuff for grinding evenly and continuously into the grinding chamber of the main frame. Due to the centrifugal force in rotation, the roller swings go outward and presses closely upon the ring. The shovel carries the stuff to the space between the roller and ring. When the roller rolls, the stuff is thus grinded.
After being grinded, the stuff is to be routed to the classifier along wind belt of the blower and the rough powder will be put back to the grinder for regrinding. The fine powder flows into the cyclone collector together with air flow and is expelled from the powder output pipe as product.
In the grinding chamber, since the stuff contains moisture to some extent, the heat generated during grinding makes the moisture evaporate; 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 in negative pressure, the increased air flow is guided to the deduster and sequentially to the atmosphere after purification.
Raymond Mill Features
1. Raymond mill plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing is an independent production system.
2. Compared with other milling plants or traditional Raymond mill, its passing ratio achieves 99%, this is what other grinding mill cannot reach.
3. Our Raymond mill's driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.
4. The electric control system of Raymond mill is centralized controlled, so the automatically is high, no people are needed in the operating room when the Raymond mill is working.
5. Raymond mill is easy to adjust, small in dimension, light in weight, with lower oil and power consumption and easy to maintain.
