Automatic-grinding and automatic-crushing roller screen

Abstract

The invention relates to an automatic-grinding and automatic-crushing roller screen. The automatic-grinding and automatic-crushing roller screen comprises a driving system, a base, idler wheels, a roller, a longitudinal beam and a sieve plate. The diving system and the idler wheels are mounted on a base frame. The sieve plate is composed of a ring beam and sieve strips. The sieve plate is in the shape of a cylinder or a circular truncated cone. Each sieve strip is in a long batten shape. The vertical edge of one side of each sieve strip in called a working part, and the vertical edge of the other side of each sieve strip is called an abdomen part. The working part of each sieve strip is in a convex edge shape. The sieve strips are mounted on the inner ring of the ring beam in a mutually spaced mode, and each sieve strip is distributed in the direction of the generatrix of the sieve plate. Sieve grooves are formed by gaps between the sieve strips, and at least one lifting trough plate is arranged on the sieve plate. The sieve plate is connected with the inner ring of the roller through the longitudinal beam, so that a roller screen body is formed. The idler wheels are mounted on the base, and the two idler wheels are arranged under the roller in a supporting mode. The automatic-grinding and automatic-crushing roller screen has the advantages that striping, crushing, automatic grinding and screening are integrated, and the automatic-grinding and automatic-crushing roller screen is suitable for processing of large industrial solid waste and building solid waste which are difficult to treat.

Description

technical field [0001] The invention relates to a self-grinding and self-breaking roller sieve, which belongs to the technical field of crushing, grinding, separation of covered materials and screening of materials. Background technique [0002] In the prior art, different equipments are used for grinding, crushing, sieving and stripping of materials, and each equipment belongs to different fields. Traditional mills include: autogenous mills, ball mills, rod mills, and Raymond mills; they have large motor power, high energy consumption, fragile bearings, easily damaged liners, easy to grind, difficult to replace, low production capacity, and inability to produce coarse and fine materials. Instant separation, high production cost, small feed particle size and many other disadvantages. Existing crushers include: jaw crusher, impact crusher, vertical shaft crusher, cone crusher, etc., all of which have problems such as large pieces of metallurgical slag, which cannot be peeled...

AI Technical Summary

Problems solved by technology

Traditional mills include: autogenous mills, ball mills, rod mills, and Raymond mills; they have large motor power, high energy consumption, fragile bearings, easily damaged liners, easy to grind, difficult to replace, low production capacity, and inability to produce coarse and fine materials. Instant separation, high production cost, small feed particle size and many other disadvantages

Existing crushers include: jaw crusher, impact crusher, vertical shaft crusher, cone crusher, etc., all of which have problems such as large pieces of metallurgical slag, which cannot be peeled off from slag and iron, limited feed models, small feed particle size, and regardless of thickness , over-crushing of materials, waste of resources and many other disadvantages

Existing roller sieves include a crushing roller sieve that only breaks casting sand and modules. The central axis, support frame, rollers, rollers, screen mesh, and spiral feeding plate are easy to wear and tear, difficult to maintain, and the screen mesh or joists are not durable. smashing, unable to bear heavy loads, unable to screen larger materials, and unable to crush hard materials such as ore and metallurgical slag. High, frequent replacement of wearing parts, low production capacity, unable to separate the slag from the iron, unable to separate the stripped slag into overscreen and underscreen in time, unable to realize on-site adjustment of the sieve slot gap without waste, and short replacement time

It is impossible to realize self-grinding, self-breaking, screening, stripping and other functions at the same time, and it is impossible to realize the horizontal installation of roller sieve. defect

The three types of equipment in the prior art have single performance, including many repetitive and complicated defects such as feeding, discharging, conveying, land occupation, construction, manual work, lubrication, maintenance, energy consumption, environmental protection, and inability to link.
