Belt conveyor

Brief introduction

Belt conveyor is a kind of friction drive by the continuous mode transportation machinery materials. Is mainly composed of a machine frame, conveying belt, a belt roller, tensioning device, transmission device. It can be the material in certain transportation line, from the initial material to the final point of discharge is formed between a material conveying process. It not only can be broken loose material conveying, can also be carried into pieces of goods transportation. In addition to the pure material handling, but also with various industrial enterprise production process in process requirements are matched, formation of rhythmic flow transport line.

Belt conveyor can be used for horizontal transport or incline transportation, use very convenient, widely used in modern industrial enterprises, such as: mine underground tunnel, mine transportation system on the ground, open pit mining and ore dressing plant of.

Working principle

Belt conveyer is mainly composed of a two endpoint roller and a sleeve on the closure of conveyor belt. Drives the conveyer belt to the rotating drum known as the drive roller ( drum drive ); another is the only change in the direction of conveyor belt movement known as the drum to drum. Drive roller driven by motor through reducer, belt drive roller and a conveying belt by friction drag. Driven roller are generally installed in the discharge end, so as to increase the traction force, is conducive to drag. Material from the feed end feeding, falls on the rotation of the conveyor belt, conveyor belt friction drive on transport bag unloading unloading.

The main types of belt machine

Turning machine belt, climbing belt machine, straight belt machine, belt machine (45 degree belt, fan belt machine ), light belt machine, narrow type belt machine, telescopic belt conveyer, belt conveyer, belt conveyer for loading and unloading

Conveyer development history

Chinese ancient high rotating cylinder and water roll, is a modern bucket conveyor and scraper conveyor rudiment; seventeenth Century, start the application frame

Air cable conveying bulk material; the middle of the nineteenth Century, various modern structure of conveyer appears in succession.

In 1868, in the UK there belt conveyors;1887, appeared in the United States of screw conveyor;1905, in Switzerland the strip conveyor;1906, in the UK and Germany emerged inertial conveyer. Thereafter, conveyer by machinery manufacturing, motor, chemical and metallurgical industry technology progress effect, perfect ceaselessly, progressively by complete workshop internal transportation, development to completion in the enterprise, between enterprises and between the city of material handling material handling system, become the mechanization and automation part.

Characteristic

Belt conveyer is the most ideal efficient continuous transport equipment, and other transportation equipment ( such as locomotive class ), with long conveying distance, large capacity, the advantages of continuous conveying, and reliable operation, easy to realize automatic and centralized control, especially for high production and high efficient mine, belt conveyor has become coal mining mechanical and electrical integration technology and equipment of key equipment. Belt conveyor is the main characteristics of the body can be very convenient telescopic, a belt storage, tail with the coal mining working face advancing to lengthen or shorten, compact structure, can do not have a basis, directly in the roadway floor laying rack, lightweight, convenient disassembly. When the transmission capacity and distance is larger, with the middle drive to meet the requirements. According to the transportation process requirements, can be a single conveyor, also can machine are combined into a horizontal or inclined transportation system to transport materials.

Belt conveyor is widely used in coal, electricity, transportation, chemical industry, because it has large capacity, simple structure, convenient repair, low cost, high universality and so.

Belt conveyor is also used in building materials, electric power, light industry, food, ports, ships and other departments.

Technical advantages

The first is that it is reliable in operation. In many continuous operation of the important production units, such as power plant of the transportation of coal, steel and cement bulk material conveying, and port handling of ships were using belt conveyor. In these occasions such as shutdown, the loss is huge. When necessary, belt conveyor can be a class with a class of continuous work.
