30 kW Raymond mill for ore

30 kW Raymond mill for oreIt can grind various non flammable and explosive materials such as limestone, dolomite, calcite, marble, barite, talc, gypsum, vermiculite, zeolite, bentonite, kaolin, shale, purple sandstone, feldspar, quartz, etc. with a Mohs hardness of 9.3 or below and humidity below 6%. The particle size of the finished product can be adjusted between 0.613-0.033mm.

working principle

Performance characteristics

1. The grinding system is equipped with a spring pressure device, which increases the grinding pressure of the grinding roller by 800-1200kg, and increases the efficiency by 20-30% compared to ordinary grinding machines under the same power conditions.

2. The grinding roller bearing chamber adopts an overlapping multi-stage seal, greatly improving the service life of the bearing.

3. The speed adjustment of the analyzer adopts a continuously variable transmission, making it convenient and fast to adjust the particle size of the finished product.

4. The host and the powder selector are flexibly connected, and the shock-absorbing spring and sealing belt not only reduce the vibration and noise of the equipment, but also avoid resonance between the host and the powder selector.

5. The whole machine has a compact structure, occupies a small area, and is easy to operate and use.

The electric motor drives the eccentric sleeve to rotate through the belt pulley, V-belt, transmission shaft, and bevel gear. The main shaft rotates and swings under the pressure of the eccentric sleeve, causing the crushing wall above the main shaft to sometimes approach and sometimes leave the rolling bowl wall. The material is continuously impacted, squeezed, and bent in the annular crushing chamber formed by the crushing wall and rolling bowl wall, and is crushed. The crushed material is discharged from the bottom discharge port.
