Screening equipment for elongated and flaky particles in aggregate

Abstract

The invention provides screening equipment for elongated and flaky particles in aggregate. The screening equipment for the flat-elongated particles in the aggregate comprises a material screening frame, buffer positioning frame structures, a guide-in hopper, a vibration motor, a preliminary material guide-out frame structure, a material guide plate, a transverse plate, a material guide hole, a transverse movable frame structure, a powder finished product separation frame structure, an L-shaped connecting plate, a horizontal plate, a storage hopper, a control plate and a control switch, the buffer positioning frame structures are installed on the left side and the right side of the lower portion of the material screening frame, the lead-in hopper is inserted into the upper part of the left side of the material screening frame, and the preliminary material guiding-out frame structure is installed on the upper portion of the inner side of the material screening frame. According to the screening equipment for the elongated and flaky particles in the aggregate, triangular cutting frames are welded to the left side and the right side of the upper portion of a discharging hole, so that cutting off is advantageously and conveniently carried out on elongated pieces inserted into the discharging hole in the using process; and a limiting frame screw is mounted on the inner side of a longitudinal frame, and therefore the limiting function can be conveniently achieved on the longitudinal frame during use, and the longitudinal frame can be prevented from being ejected out of a positioning hole under the action of a buffer spring.

Description

technical field [0001] The invention belongs to the technical field of particle screening, and in particular relates to screening equipment for needle-like flake particles in aggregate. Background technique [0002] The screening machine is a vibrating screening mechanical equipment that uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divide materials such as sand, gravel and crushed stone into different grades according to the particle size. The screening process of the sieving machine is generally continuous. After the sieving raw materials are fed to the screening machine, the materials smaller than the sieve size pass through the sieve holes, which are called under-sieve products, and the materials larger than the sieve size are continuously discharged from the sieve surface. , known as the sieve product, the sieve particle level depends on the sieve surface, the sieve surface is divide...
