Forced discharge pulverizing mill for crushed materials

Abstract

The invention discloses a forced discharge pulverizing mill for crushed materials. In the invention, no pulverizing medium is needed, the product purity is increased, materials blocks which are 300 millimeters in diameter can be pulverized into particles of which the particle sizes are less than 0.074 millimeter at one time, and the material crushing flow is simplified; by replacing a lining plate, the requirements of different particle sizes and yield are met, the equipment is utilized to the maximum extent simultaneously, and the investment cost is saved; and the service life of a barrel is prolonged, and the maintenance cost of the equipment is lowered. The forced discharge pulverizing mill consists of a feeding part, a main bearing, a revolving part, a driven gear, a discharging part, a driving gear, a speed reducer, a main motor, a low-speed driving device, a feeding hole, a feeding end cover gland, a feeding end cover, a bolt, a lining plate connecting bolt, a rubber plate, a barrel lining plate, a shifting board, a discharging end cover corrugated plate, a trough plate, a discharging screw, a discharging end cover, a gear cover, a discharging end cover gland, a barrel flange, a feeding end cover corrugated plate, a barrel, a pushing device, a pressure strip and a feeding spiral port. The forced discharge pulverizing mill has a simple and compact structure, and the production efficiency is increased.

Description

technical field [0001] The invention relates to a pulverizer, in particular to a forced discharge pulverizer for crushing materials. Background technique [0002] At present, ball mills are generally used as grinding equipment in the comprehensive recovery and reuse process of alumina crusts. The action mode of the ball mill is: the cylinder rotates to drive the materials and grinding media. Under the action of centrifugal force, the materials and media are brought to a certain height and then fall freely and impact the materials in the lower part of the cylinder, thereby realizing the crushing of the materials impacted by the grinding media and the mutual interaction of materials. The grinding purpose generated by the friction and rolling between them. However, this method can only be used to crush materials with smaller particles. For materials with larger particles, it cannot be added at one time. It needs to be manually crushed for the first time and then grinded with a...

Problems solved by technology

However, this method can only be used to crush materials with smaller particles. For materials with larger particles, it cannot be added at one time. It needs to be manually crushed for the first time and then ground with a ball mill, resulting in low working efficiency of the equipment; and the existing equipment structure is heavy, It occupies a large space and increases the cost of equipment use; the structural form of the equipment makes the product granularity single, which cannot meet the requirements of various product granularity and output
