YGM series European strength grinding mill (upgraded Raymond mill) is a high capacity, energy-saving, environmentally friendly, and strong type high-end equipment that have many advantages with the longterm research and development production practice of the suspension rollers Raymond Mill in the company, which combines the experience of more than 3,000 powder customers at home and abroad, and gathers the best performance parameter configuration. Widely used in mining, building materials, electric power, road and bridge, coal, metallurgy, chemical, ceramics, refractory materials, etc. The grinding mill is suitable for processing all kinds of non-flammable and explosive materials with Mohs hardness below 9.3 and humidity below 6%. The fineness of the finished
product is 80-800mesh. Special devices can also be added to grind out 30~80 mesh coarse powder.
1.Optimized Device:Adopts the heavy type design, which fully considers the grinding efficiency and service life, and has achieved many key breakthrough.
2.Reduce Resistance:Adopting high pressure blower adjusting the airflow; the curved wind duct design and non-resistance wind inlet snail shell design, reducing the resistance of airflow.
3.Negative Pressure:According to the actual needs of users, it can be an open circuit system that allows the system to run the mill at full negative pressure to ensure longterm continuous. 4.New Reducer:It adopts the new reducer drive, which is reliable and stable in operation and convenient to use and maintain.
5.Grinding and drying two-in-one
Suitable material that can be grinding:such as barite, calcite, zeolite,potassium feldspar, talc, marble, limestone, dolomite,fluorite and lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass and thermalinsulation material in mine, metallurgy, chemistry and building industry.
Raymond Mill's working principle is that the grinding roller is rolled tightly on the grinding ring under the action of centrifugal force. The shovel scoops the material to the middle of the grinding roller and the grinding ring. The material is broken into powder under the action of the grinding pressure, and then Under the
Materials
Limestone,calcite,calcium carbonate,dolomite,barite,basalt,granite,pebbles,talc, gypsum, diabase, quartzite,
bentonite,glass,activated carbon etc.
Application Field
Calcium carbonate crushing, gypsum powder processing, power plant desulfurization, non-metallic ore pulverizing, coal powder
preparation,etc
Work Principle
The materials to be crushed are added into the machine from the feed hopper on the side of the machine casing, and rely on the grinding roller device suspended on the plum blossom frame of the main machine to revolve around the vertical axis and at the same time rotate on its own. Due to the centrifugal force during rotation, The grinding roller swings outward and presses against the grinding ring, causing the blade to scoop up the material and send it between the grinding roller and the grinding ring. The rolling and crushing of the grinding roller achieves the purpose of crushing the material.
Air separation process: After the material is ground, the fan blows the wind into the main casing, blowing up the powder, which is sorted by the analyzer placed above the grinding chamber. Materials that are too fine and too coarse fall into the grinding chamber for regrinding. The powder that meets the specifications enters the cyclone collector with the wind flow, and is collected and discharged through the powder outlet, which is the finished product. The air flow returns to the fan from the return duct at the upper end of the large cyclone collector. The air path is circular and flows under negative pressure. The increased air volume in the circulating air path is discharged through the exhaust pipe between the fan and the host machine and enters the small cyclone collection device for purification.
Product Advantages
1:High efficiency and precision classifier, unique airtightness, which canensure the quality of end products.
2:The wear-resistant volute can effectively improve the material liquidity, decrease the air volume loss and avoid air energy loss.
3:The bevel gear overall dive can achieve higher transmission efficiency, easy to install and adjust, long service life and lower cost.
4:Inner thin oil lubrication system can realize lubrication between main bearing and drive bearing without any additional lubrication pump, easy to maintenance.
5. The curved surface shovel with split design, only the blade to be replaced during maintenance, thus the shovel has long service life.
6.The isolated cyclone collector can effectively improving the classifying efficiency and accuracy.
