Reciprocating type vibrating screen

Abstract

The invention discloses a reciprocating type vibrating screen. The reciprocating type vibrating screen comprises a base, a spring, a rack, vibrating motors, reciprocating driving devices, a screen net frame and a combined screen net, wherein the rack is connected with the base through the spring; the vibrating motors are correspondingly mounted on two opposite side surfaces of the rack, and the reciprocating driving devices are mounted on one side surface, adjacent to the side surfaces equipped with the vibrating motors, of the rack; the reciprocating driving devices are connected with the screen net frame and can drive the screen net frame to reciprocate; the combined screen net is detachably positioned on the screen net frame; two discharging ports are formed in the lower part of the combined screen net. According to the reciprocating type vibrating screen, the vibrating motors perform vibrating while the reciprocating moving type screening is carried out, so that materials can be spread to the whole screen net, and as a result, the use area of the screen surface can be increased, and the screening efficiency can be improved; elastic balls are positioned in the combined screen net and can pump to strike the screen net to scatter the agglomerated materials, and as a result, the screening effect can be improved; meanwhile, the screen net can be greatly prevented from being blocked, so that the service life of the screen net can be prolonged.

Description

technical field [0001] The invention relates to a reciprocating vibrating screen. Background technique [0002] In the mineral processing process, it generally goes through the process of ball mill crushing and screening, and the mining vibrating screen is used as the mineral processing and screening equipment, and the screening effect is directly related to the recovery index of the final mineral processing. After ball milling and rod milling, a large amount of ore needs to be screened, so the screening capacity of the vibrating screen is playing an increasingly important role in the mineral processing industry. The traditional vibrating screen usually moves in a straight line. When using this method for screening, the material moves forward in a straight line on the screen surface, and the utilization rate of the screen surface is low; The material is screened, but the screening effect of the upper material is poor. At the same time, there are phenomena such as the screen...

Problems solved by technology

The traditional vibrating screen usually moves in a straight line. When using this method for screening, the material moves forward in a straight line on the screen surface, and the utilization rate of the screen surface is low; The material is screened, but the screening effect of the upper material is poor. At the same time, the screen is easy to be blocked during use, which affects the screening effect and causes the screened material to be unqualified.
