The new roller assembly description: The new roller assembly to change the traditional structure form Raymond 5, using a variety of sealing means, excluding the veterans into the oil spill, into dust, three different heart defects. Several major advantages of the new assembly: 1, no leakage, no one group of fuel, only three to one days once a small amount of additional oil. 2, the high degree of sealing, easy assembly within the production process into the dust, thus extending bearing life. 3, in the production process according to the degree of wear of the bearing assembly, the adjustable bearing clearance 3r8830 Raymond, guaranteed upper and lower bearings concentric, bearing more than ten months of continuous use. 4, the new roller assembly to extend the maintenance cycle, reducing maintenance intensity, Raymond reduce production costs, improve production efficiency, can bring considerable economic benefits to the user. Raymond low inside the motor and mill grinding rod mill grinding and abrasive materials require high quality ore grinding equipment requirements with sufficient abrasion resistance Raymond 3r, dawn ore Raymond machine gears and wheels enclosed gearbox. High quality of the final product concentrate sorting operation called selection; poor product will roughing after further sorting, separation of the ore to rougher or alone, poor product scavenger tailings after that. Sorting operations, by means of re-election, magnetic separation, electrostatic separation, flotation, and other useful minerals beneficiation methods with gangue separation, and useful minerals are separated to obtain the final product beneficiation. Sorting operations at the beginning of the sorting become rougher; monomer solution between various useful minerals from each other.
