TD75 Universal Belt Conveyor for Mining/ Power/ Port/ Coal/ Building Materials Industry

TD75 universal belt conveyor is widely used in metallurgy, mining, coal, port, transportation, water and electricity, chemical industry and other departments, for loading, unloading, transferring or piling up all kinds of loose materials or finished goods with a density of 500~2500kg/m3 at room temperature. , due to the equipment has simple structure, easy maintenance, low cost, the advantages of strong commonality, belt conveyor by single or multiple synthetic transportation system for conveying material, according to the technological requirements can be decorated in the form of horizontal or inclined, belt conveyor besides can meet the requirements of horizontal or inclined conveyor, also can be used with convex segmental arc, concave segmental arc and straight line combination form of transport;

The material lumpiness allowed by belt conveyor mainly depends on bandwidth, belt speed, groove Angle and dip Angle, and also depends on the frequency of bulk material. At present, the applicable working environment temperature of the belt conveyor is generally -15°C to 40°C. In addition, CMN Transmission produces TD75 light belt conveyors, which can be customized for different occasions.

Application of Belt Conveyor

• Mining Industry
  In underground coal mines, the TD75 belt conveyor is used to transport coal from the working face to underground coal bunkers or directly to the surface. Its strong conveying capacity significantly improves coal transportation efficiency. For example, in medium-sized coal mines, a proper layout of TD75 conveyors can achieve the continuous transport of several thousand tons of coal per day.
  In metal mines (e.g., iron ore, copper ore) and non-metallic mines (e.g., limestone, gypsum), the conveyor transports ore from the mining site to beneficiation plants or stockpiles. It can handle a wide range of material sizes from fine ore powders to large ore lumps.
• Ports and Terminals
  The TD75 type belt conveyor is used for loading and unloading bulk materials such as coal, ores, grain, and fertilizers. When unloading large bulk carriers, it can work in tandem with grab cranes to quickly transfer cargo to stockyards or warehouses.
  During loading operations, it transfers goods from storage areas into ship holds, improving efficiency. Although container handling dominates modern ports, TD75 belt conveyors are also used in auxiliary areas, such as warehouses storing container fillers (e.g., wood chips, foam), to transport these materials.
• Power Industry
  In thermal power plants, the TD75 belt conveyor is a key system for transporting coal from the coal yard to the raw coal bunker of the boiler room, ensuring continuous power generation.
  It is also used to transport ash generated from coal combustion to ash yards or treatment facilities for reuse, helping to solve ash disposal problems and reduce environmental pollution.
• Building Materials Industry
  During cement production, the TD75 universal fixed belt conveyor transports raw materials such as limestone, clay, and iron ore to the raw mill and delivers finished cement to storage silos or packaging lines.
  It enables efficient material flow across different production stages. It is also suitable for transporting ceramic raw materials like kaolin and quartz sand from material reception and batching to the forming workshop, ensuring accurate and timely supply.
• Grain Processing and Storage
  At grain collection stations and large grain depots, the TD75 belt conveyor transports raw grains like rice, wheat, and corn from unloading points to silos, reducing handling loss and contamination.
  In grain processing plants, it conveys materials between each production stage from cleaning and de-stoning to grinding and packaging, ensuring smooth and continuous processing.
