Raymond mill to solve the industrial molybdenum refinement size

1, of the problem As the molybdenum market continues to widen, the user of the product quality requirements higher and higher: industrial molybdenum oxide as the main export raymond mill USE of our company, its appearance quality processing enterprise product sales will have a immeasurable impact. In order to meet market demand, by the end of 1993 the company proposed to produce a particle size of 1mm or less industrial molybdenum oxide was used as the processing of the product smelter only one ball mill 900mm × 1800mm, and its production. When the desired particle size of less than 1mm or less accounted for more than 96 percent qualified products, thus completing 200t qualified products to maximize the equipment is done monthly, plus the equipment itself into the drain spout of serious scene dusty materials, labor intensive, and the recovery low adverse factors exist, and the liner screw failure higher frequent maintenance, etc., no longer suited to the time of production. For the implementation of marketing plans, after inspection and verification aspects Raymond decided to refine the product size. 2, the physical properties of the product to be processed I plant with a multiple hearth furnaces original production of industrial molybdenum oxide, its hardness as follows: Sintered black Mohs 7 accounted for 2% to 3%, Mohs 2-3 accounted for about 98%. Bulk density: 1.766g / cm3 Bulk Density: 2.369g / cm3 Apparent specific gravity: 2.504g / cm3 True specific gravity: 3.571g / cm3 Particle size of the above tests is less than 1mm, containing Mo58% of the raw material of.
