Ore crushing and screening equipment

Abstract

The invention discloses ore crushing and screening equipment which comprises a housing; a charge hole is formed in the top of the housing; a crushing roller is arranged in an inner cavity of the housing; an inner cavity of the crushing roller is connected to a rotary shaft in a penetrating manner; the left side of the rotary shaft is connected to a shaft coupler; the left side of the shaft coupler is connected to a motor; the bottom of the housing is equipped with a discharge hole; the two sides of the bottom of the housing are connected with supporting posts; a screen is arranged between the two supporting posts; the screen comprises a framework; screen slots are formed at the inner side of the framework at equal distance; the inner cavity of the framework is separately equipped with a transverse reinforcement screen strip and a vertical reinforcement screen strip through the screen slots; screws are arranged at the two sides of each of an inner cavity of the transverse reinforcement screen strip and an inner cavity of the vertical reinforcement screen strip; a vibrating motor is arranged at one side of the top of the screen; the two sides of the bottom of the screen are connected with struts; a material collecting slot is formed between the two struts; and damping springs are arranged at the outer sides of the struts. According to the ore crushing and screening equipment disclosed by the invention, the integral screen does not need to replace when the screen is damaged, so that cost during ore screening can be reduced.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to ore crushing and screening equipment. Background technique [0002] Mines include coal mines, metal mines, non-metal mines, building materials mines and chemical mines. The scale of mines is usually expressed by annual output or daily output. Small-scale three-medium type, the size of the mine should be compatible with the economically reasonable service life of the mine. Only in this way can infrastructure costs be saved and costs reduced. In the mine production process, mining operations consume the most manpower and material resources and occupy funds. At most, it is the production link with the greatest potential to reduce mining costs. The main way to reduce mining costs is to improve labor productivity and product quality, and reduce material consumption. [0003] At present, the ore needs to be screened after the ore is broken, and the screen is used for screening. The scr...
