Belt conveyor, also known as belt conveyor, is widely used in household appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food and other industries, as well as the assembly, testing, commissioning, packaging and transportation of objects
Line conveying can be selected according to process requirements   : Common continuous operation, beat operation, variable speed operation and other control modes; The line body shall be selected according to local conditions: straight line, curve, slope and other line form conveying equipment includes belt conveyor, also known as belt conveyor or belt conveyor, which is an indispensable economic logistics conveying equipment for forming a rhythmic flow line
According to its conveying capacity, belt conveyor can be divided into heavy belt conveyor, such as mining belt conveyor, and light belt conveyor, such as used in electronic plastics, food, light industry, chemical medicine and other industries
The belt conveyor has the advantages of strong conveying capacity, long conveying distance, simple structure and easy maintenance
It can easily implement programmed control and automatic operation
The continuous or intermittent movement of the conveyor belt is used to transport articles below 100kg or powdery and granular articles
It runs at a high speed, stably, with low noise, and can be transported up and down the slope
Development history: the high rotary drum car and the tipping car carrying water in ancient China are the rudiments of modern bucket elevator and scraper conveyor; In the 17th century, aerial ropeways were used to transport bulk materials; In the middle of the 19th century, conveyors of various modern structures appeared one after another [3] 。
In 1868, belt conveyor appeared in England; In 1887, screw conveyor appeared in the United States; In 1905, the steel belt conveyor appeared in Switzerland; In 1906, inertia conveyors appeared in Britain and Germany
Since then, the conveyor has been continuously improved under the influence of the technological progress of machinery manufacturing, motor, chemical industry and metallurgical industry
It has gradually developed from completing the transportation within the workshop to completing the material handling within the enterprise, between enterprises and even between cities
It has become an indispensable part of the mechanization and automation of the material handling system
It shows that belt conveyor is a kind of friction driven machinery that transports materials in a continuous way
It is mainly composed of frame, conveyor belt, idler, roller, tensioning device, transmission device, etc
It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line
It can carry out the transportation of both broken materials and finished articles
In addition to pure material transportation, it can also cooperate with the requirements of the process in the production process of various industrial enterprises to form a rhythmic flow operation transportation line
Belt conveyor is also known as belt conveyor
The conveyor belt moves according to the friction transmission principle
It is suitable for conveying powdery, granular, small block shaped low abrasive materials and bagged materials with a bulk density of less than 1
67/ ton / cubic meter, such as coal, gravel, sand, cement, fertilizer, grain, etc
The belt conveyor can be used within the ambient temperature range of -20 ℃ to +40 ℃, and the temperature of the delivered material is less than 60 ℃
Its length and assembly form can be determined according to the user's requirements
The drive can be either an electric roller or a drive device with a drive frame
Features belt conveyor is the most ideal efficient continuous transportation equipment in coal mine
Compared with other transportation equipment (such as locomotive), it has the advantages of long transportation distance, large transportation volume, continuous transportation, reliable operation, easy to realize automation and centralized control
Especially for high-yield and high-efficiency mines, belt conveyor has become the key equipment of electromechanical integration technology and equipment in coal mining
The main characteristics of the belt conveyor are that the machine body can be easily retracted, with a belt storage bin
The tail can be extended or shortened with the advance of the coal mining face
The structure is compact
It can be laid directly on the roadway floor without a foundation
The frame is light and convenient for disassembly and assembly
When the conveying capacity and haul distance are large, the intermediate drive device can be equipped to meet the requirements
According to the requirements of the conveying process, the materials can be conveyed by single machine or by multi unit combined horizontal or inclined conveying system
Belt conveyor is widely used in metallurgy, coal, transportation, water and electricity, chemical industry and other departments because it has the advantages of large conveying capacity, simple structure, convenient maintenance, low cost and strong universality
Belt conveyors are also used in building materials, electric power, light industry, grain, ports, ships and other departments
