This article is mainly about the introduction of the tumbler screen and its features.

The flexible connection between inlet and outlet of the swinging dry particle screen was prone to aging or damaging, causing dust leakage, environmental pollution, and an increase in production costs. The present paper provided several solutions to this problem, involving the reasonable design and installation of the sluice of the tumbler screen and a sound selection of flexible connections.

Steep inclined belt conveyor has the advantages of simple structure, reliable operation and convenient maintenance, and can realize large inclination or vertical transportation, compact structure, small footprint, so it is an ideal equipment for large inclination transportation. steep inclined belt conveyor is a kind of most of the parts the same as the ordinary belt conveyor, line layout and form a relatively stable structure, a series of components, accounting for a large proportion of the general parts, so it can be based on the general belt conveyor series of 3D model of the parts and impr

The structural feature of the steep incline belt conveyor is to replace the ordinary conveyor belt with a corrugated sidewall belt. Its working principle and structural composition are similar to those of belt conveyors. Therefore, components such as driving device, tensioning device, intermediate frame, intermediate leg, tailstock, drive roller, reversing roller, idler, discharge funnel, air cleaner, protection device, etc. The corresponding parts of the conveyor are universal.

Steep inclined belt conveyor is a kind of conveying machine developing on the basis of ordinary belt conveyor. In order to realize the material transportation under the condition of large angle and long distance, so as to give full play the function of transportation equipment. However, there will be material falling phenomenon in the process of transportation. In this case, we designed several protective measures to eliminate accident risks.

Large inclination corrugated sidewall belt conveyor in our country is a new kind of belt conveyor. For a period of time, a number of domestic and foreign research institutions and manufacturers were committed to research, develop and manufacture large inclination corrugated sidewall belt conveyor.This paper is mainly introduce steep angle corrugated sidewall belt conveyor. Besides, introducing the common faults and treatment measures of corrugated sidewall belt conveyor.

Corrugated sidewall belt conveyors is a new kind of belt conveyors. In addition to the advantages of a belt conveyor, it is especially suitable for occasions with high lifting height. This equipment technology layout is convenient, can reduce construction scale, reduce engineering cost. In addition, it is a continuous conveying machine that drives a conveyor belt by a driving drum and uses a flexible conveyor belt as a material carrier and a traction member to continuously convey the scattered materials or finished parts by friction.

The corrugated sidewall belt conveyor is a belt conveyor with an inclination of between 18 and 90 degrees. It is specially designed to transport materials that cannot be conveyed by a universal belt conveyor and can be automatically slid down on the belt, or used for belts that are space limited and can only be baffled. The corrugated sidewall belt conveyor has the advantage of compact structure and small footprint and is ideal device. It is suitable for underground mining and underground construction, open pit mining, large dumping machines and other fields.

This essay discusses the structure design of corrugated sidewall belt conveyor, The structural characteristics and key points of selection of the corrugated fender conveyor belt are emphatically analyzed. It is explained that WM type corrugated sidewall can get better using effect, the layout form and supporting form of the corrugated sidewall belt conveyor are discussed in detail, and the general principles of structural design of the corrugated fender belt conveyor are given.

The trommel screen is a kind of high precision fine powder screening machine with low noise and high efficiency. This paper mainly analyzes the factors influencing the screening effect of trommel screen from the aspects of particle size, feeding speed, sieve inclination angle, particle shape and effective drum screen screening area.

The structure of the improved trommel screen is more simple and reasonable. The utility of use of the trommel screen will be enhanced, the screening process will be more reasonable and the screening effect will be better. This paper only analysis the improved design of the trommel screen, it dose not involve the calculation and selection of the supporting dust removal system.

This paper analyzes the waste pretreatment process and discusses the waste pretreatment method, focuses on the waste pretreatment technology of screening work, this paper introduces the waste screening of the screening technology, discusses the key equipment in screening technology - Trommel Screen, make after pretreatment of waste can realize the ultimate goal of refuse resources, reduction and harmless. And then to meet the environmental requirements of all regions to achieve green development.
