Autogenous tumbling mill for crushing aluminum oxide crusting block

Abstract

The invention discloses an autogenous tumbling mill for crushing an aluminum oxide crusting block. By the autogenous tumbling mill, media are not required to be ground, so that the purity of a product is improved; a block of which the diameter is less than or equal to 300mm can be changed into particles of which the particle size is less than 0.075mm after being ground at a time, so that a material crushing process is simplified, and working efficiency is improved; and the abrasion resistance of a lining plate is improved, the service life of barrel bodies is effectively prolonged, and the maintenance cost of equipment is reduced. The autogenous tumbling mill consists of a feeding part, a main bearing part, a rotary part, a driven gear, a discharging part, a driving gear, a speed reducer, an active motor, a slow speed driving device, a hollow shaft neck, a feeding end gland, a feeding end hollow shaft neck, a bolt, a lining plate connecting bolt, a discharging end hollow shaft neck, a gear cover, a discharging end gland, an end cover lining plate, a cone end cover, a barrel body flange, a barrel body, a barrel body lining plate and a rubber pad. The autogenous tumbling mill has a simple structure, is convenient to use, is safely operated, is wear resistant and durable and saves occupied space and consumable materials of equipment.

Description

technical field [0001] The invention relates to an autogenous mill, in particular to an autogenous mill for crushing alumina crust blocks. Background technique [0002] At present, in the process of comprehensive recovery and reuse of alumina crusts, ball mills are generally used as grinding equipment; the function of ball mills is: the cylinder rotates to drive the materials and grinding media, and under the action of centrifugal force, the materials and grinding media are brought to a certain height Afterwards, it falls freely and impacts the material in the lower part of the cylinder, thereby achieving the purpose of crushing the material impacted by the grinding medium and grinding caused by the friction and rolling of the materials. 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 ball mill, resul...

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 grinded with a ball mill, resulting in low working efficiency of the equipment; and the existing equipment structure is heavy, It occupies a large space, the speed cannot be adjusted, and the particle size of the crushed material cannot be controlled. Secondly, the lining plate of the protective cylinder is not wear-resistant and needs to be replaced frequently, which increases the cost of equipment to a certain extent; In the finished material, the purity of the finished material is affected accordingly
