Cleated belt conveyor is widely used in coal, grain, building materials, chemical industry, hydropower and metallurgy industries. In the range of – 19 ℃ – + 40 ℃, it transports all kinds of easily scattered powder, granular, small block, paste and liquid materials with a stacking proportion of 0.5-2.5 t/m³.

Material handling equipment are designed such that they facilitate easy, cheap, fast and safe loading and unloading with least human interference. For instance, belt conveyor system can be employed for easy handling of materials beyond human capacity in terms of weight and height. This paper discusses the design calculations and considerations

Designing a Conveyor System

Conveyors used in coal, mineral and rock mining require a more sophisticated analysis than in the past due to the complex nature of the modern mine and its demand on equipment component design. This is particularly true in mines that use longwall extraction and long belt conveyors.

spillage, leakage and dust generation. It is common practice not to load coal conveyors to their capacity in order to accommodate surge loads and to reduce spillage and leakage due to mistracking. A capacity design factor, DF, of 1.20 (83% of theoretical maximum capacity) is often used in handling coal in coal fired power plants.

Belt conveyors are one of the most common systems in the field of bulk materials handling. Such systems are typically used to convey bulk materials such as …

Cross belt sampling system is a common sampling system in the sampling industry. The cross belt sampling system includes primary sampler, sample divider, primary feeders, sample crusher, and the PLC control system. We provide the belt samplers which are used in the head and center of the belt conveyor. The belt sampler can be used for mineral powder, raw coal, …

The unloader failed to deliver the design throughput of 1400 tn/hr at 400 rev/min with the installed motor power of, nominally, 430, kW. Samples of the coal were delivered to the University of Newcastle for testing. The moisture content of the coal, as-supplied, was 27%, which was at the top end of the specified moisture level for acceptance.

We use belts made from fabric or rubber. Belt conveyors are commonly used in both manufacturing and distribution facilities. Ultimation designs and builds systems from 5′ long to 102′ long and in widths from 6″ wide belts up to 72″ wide. They are great for transporting regular and irregular shaped objects.
