4R Raymond mill：
Application range of 4R Raymond mill
Are widely used in metallurgy, building materials, chemical industry, mines and other minerals in the field of grinding materials processing, suitable for processing mohs hardness under seven, humidity under 6% of all kinds of inflammable and explosive minerals, such as gypsum, talc, calcite, limestone, marble, potassium feldspar, barite, dolomite, granite, kaolin, bentonite, medical stone, bauxite, iron oxide red, iron ore, etc., product fineness of 440 microns to 613 microns (0.613 mm to 0.613 mm), through the analysis of the combination of machine and fan, can meet the requirements of different users.
4R Raymond mill working principle
Began to work, grinding roll around the spindle rotation, and under the effect of high pressure spring and centrifugal force, close to the ring rolling, the rolling pressure is higher than the same power under the condition of Raymond mill 1.2 times, so the production is greatly improved. When the material into the grinding chamber, the shovel knife scooping up into between grinding roller and grinding ring rolling, rolling powder with blower after cycle into the analysis of wind machine, qualified fine powder with the gas flows into the whirlwind powder is the finished product, large particles grain fall back into the ground. The circulating wind returns the blower to repeat the process, and the residual air enters the bag filter purification. When the grinding roller and grinding ring achieve certain wear, adjust the length of the high pressure spring, keep the grinding pressure between grinding roller and grinding ring. Ensure stable yield and fineness.
4R Raymond mill product features
1. Compared with other grinding machines, the output increased by 10-20% under the same dynamic conditions, and the grinding pressure of the mill roller on the material increases YGM series high-voltage suspension roller ramon mill 800-1200kg under high pressure spring.
2. The mineral materials with less than 9.3 degree of hardness can be machined and crushed.
3. The grain size range of the finished product is wide, the diameter of the particle diameter can reach 0.613mm (30 eyes), the particle diameter can reach 0.033mm (425 eyes), and the smallest material can reach 0.013mm (1000 eyes).
4. The dusting effect completely meets the national dust emission standard.
5. It is convenient to adjust the analyzer.
6. The grinding device adopts the superimposed multi-stage sealing, which is good in sealing.
