Many customers are very concerned about how to choose 100 mesh feldspar grinding mill. Because the hardness of feldspar fluctuates between 6 and 6.5, it is a relatively hard non-metallic ore. Some mills that are commonly used in the market are not ideal for feldspar, such as Raymond mill. So what is a grinding mill for 100 mesh feldspar making? That is the ball mill.
Why is the ball mill ideal grinding machine for producing 100 mesh feldspar?
Structure features of ball mill:
The ball mill is composed of a main part such as a feeding part, a discharging part, a turning part, a transmission part (a reduction gear, a small transmission gear, a motor, and an electric control). The hollow shaft is made of cast steel, the inner lining can be replaced, the rotary large gear is processed by casting hobbing, and the barrel is embedded with wear-resistant lining, which has good wear resistance. The machine runs smoothly and works reliably.
Dry ball mill and wet lattice ball mill can be selected according to materials and mining methods
Working principle of ball mill:
The ball mill is a horizontal cylindrical rotating device, external gear transmission, two bins, lattice ball mill. The material is uniformly fed into the mill by the feeding device through the hollow shaft of the feeding material. The chamber has a step liner or a corrugated liner, which is filled with steel balls of different specifications. The cylinder rotates to generate centrifugal force to bring the steel ball to a certain height. Drops, causing heavy blows and grinding on the material. After the material reaches a rough grinding in a warehouse, it enters the second warehouse through a single-layer compartment board. The warehouse is provided with a flat lining plate with steel balls inside to further grind the material. The powder is discharged through the discharge raft to complete the grinding operation.
Outstanding advantages of ball mill
1. High wear resistance and impact resistance
The advanced double-medium quenching process enables the liner to withstand tremendous impact forces during production, maintaining the surface shape of the liner during operation and reducing the deformation and wear of the liner.
2. Good lubrication and reliable operation
The displacement gear can reduce the sliding speed of the meshing and reduce the sliding ratio, thereby improving the wear resistance and the anti-gluing performance of the gear, improving the hydrodynamic performance and lubrication state of the gear transmission, and improving the reliability of the ball mill operation.
3. Insulation and cooling, long life
The diameter of the hollow shaft of the rolling bearing of the ball mill is thickened, so that the radial distance between the rolling bearing and the inlet and outlet spiral cylinder is increased, which plays a certain role of heat insulation and temperature reduction, and prolongs the service life of the bearing.
4. Energy saving, less wear and tear
Thin oil lubrication is used instead of grease lubrication to prevent poor lubrication due to lack of oil, which reduces the friction coefficient of various components such as bearings, and greatly reduces the loss rate of components.

Acccording to above information we can answer the question:What machine is suitable for grinding 100 mesh feldspar with capacity 1t/h?
That is ball mill model Ф900×1800
More about feldspar:
Feldspar is an alkali metal or alkaline earth metal aluminosilicate mineral such as potassium, sodium, calcium or strontium. The crystal structure is a framework structure. Its main components are SiO 2 , Al 2 O 3 , K 2 O, Na 2 O, CaO and the like.
Feldspar is the most important rock-forming mineral of surface rocks. Feldspar is a general term for the feldspar minerals. It is a common class of aluminosilicate-based rock-forming minerals containing calcium, sodium and potassium.
