Overflow Type Ball Mill
Overflow Type Ball Mill Overview:
The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding.
Overflow Type Ball Mill Features:
1. The jack-up device of wet grate ball mill makes maintenance easy.
2. The hydrostatic and hydrodynamic bearings ensure the smooth operation of wet grate ball mill.
3. The low speed transmission of wet grate ball mill contributes to easy overhaul and maintenance.
4. The oil-mist lubrication device guarantees reliable performance of bearings.
5. The gas clutch adopts the flexible start-up model.
Working Principle :
Principle of overflow ball mill: the main component is a cylinder with diameter and length at a reasonable proportion. Driven by the transmission device, the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in the cylinder. Due to the continuously feeding materials, the pressure pushes materials to the outlet and the grinded materials are discharged from the cylinder outlet. Qualified materials flow from the cylinder outlet. In wet grinding, the materials are taken out by the water flow. There are backpitch impellers in the hollow shaft, which can make the balls and coarse ores in the overflow return to the mill. With simple structure, higher operation rate, and rolling bearing, the energy conservation is significant.
Raymond Grinding Mill
Raymond Mill is suitable for grinding of all kinds of materials whose Mohâ??s hardness is below 9.3, such as calcium carbonate, barite, dolomite, calcite, limestone, kaolin, bentonite, marble, gypsum, quartz, feldspar, clay, talc, fluorite, clay, white mud, mica, refractory material, glass, total about 1000 kinds of materials.
Raymond Grinding Mill Features:
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.
Working Principle :
After the materials enter the grinding chamber of the main frame, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of the main shaft. The blade carries materials to the space between the grinding roller and grinding ring, and materials are ground as the grinding roller rolls. After being ground, the powder is selected by classifier via the cycle wind of the blower and the rough powder will be back to the grinding chamber for regrinding. The qualified powder is brought into the powder collector together with airflow. The powder comes out as end products while the airflow goes back to the powder collector in cycling to make the machine work normally. The remained airflow comes out after purification by dust filter.
