Wharf Belt Conveyor

Wharf belt conveyor is a belt, steel, steel fiber tape, plastic tape and synthetic materials as a transmission belt and traction workpiece transport machinery, which is characterized by a conveyor belt carrying material is passed traction member force, which is significant and other transportation machinery the difference. Carrier belt running on rollers, air can also be used, as a magnetic cushion instead of the roller bearing support without resistance band operation. Wharf belt conveyor is a continuous conveying machinery in the most widely used one, has a simple structure, transmission capacity, long distance, high reliability many advantages.

With the rapid development of China's economy, coal, electricity, mining, metallurgy, building materials, cement, chemicals, ports and other bulk material conveyor systems, extensive use of wharf belt conveyor. In 2001, China's wharf belt conveyor had reached 2 million units, of which about 120 million units in coal mines, coal boiler of about 40 million units, building materials, cement plant about 30 million units, power plants about 1 million units, about 1 ports million units (source supra).

As a material handling system, long-distance, large-capacity, high-speed, high-power wharf belt conveyor has been widely used. Particularly in the loading zone, falling from a height of material on the conveyor belt and its auxiliary devices have a great impact protection, which requires protective measures impact and abrasion resistant conveyor belt. In the coal mines and other harsh industrial environments, the system also requires flame retardant, anti-static. In this regard, China has implemented the "coal mine fire-retardant antistatic polymer articles Common test methods and criteria of" (MT113-1995) and "Determination of abrasion resistance of vulcanized rubber" (GB9867-88) and other relevant standards. Standard states: the amount of wear ≤50 mm3; alcohol burner test flaming time arithmetic mean ≤3s, flameless combustion time arithmetic mean ≤10s; arithmetic mean surface resistance ≤3 × 108Ω; impact test showed no significant surface cracks, damage.

Wharf Belt Conveyor Feature

Improve the performance of the wharf belt conveyor: To improve abrasion resistance, impact resistance, flame retardant and antistatic properties of the wharf belt conveyor, which adopted a series of major research material as a core body (skeleton layer) of the cover layer or coating.

Improve roller performance: Impact-type wear roller is commonly used components used in wharf belt conveyor, it is the prevalence of low efficiency, failure and more, short life and other shortcomings. This makes maintenance more often and conveyor long time, reduce transfer efficiency, and environmental pollution, increased operating costs, restricted the development of belt conveyors. In order to improve its abrasion resistance, impact resistance, flame retardant and antistatic properties, we have developed a series of structures and materials.

Development of wear-resistant shock device: Developed by the Shanghai SBM for loading point wharf belt conveyor belt supporting portion, alternative charging point buffer roller. Its technical features are: the application of new material combinations to meet specific, harsh working conditions; on the surface of the buffer slider nylon alloy having a low coefficient of friction, high impact toughness and high wear resistance; buffer slider intermediate rubber layer with high flexibility, which can effectively absorb the impact energy when the material falls; reliable metal frame, can withstand the impact of a large loading capacity.
