Product Description

Product Description

NN conveyor belt

The NN conveyor belt is applied for heavy loading and high-speed, middle, and long-distance materials handling. It has low elongation in warp and good trough performance in the weft, high heat resistance, high stability, good adhesion ability, and long service time features.

Performance:

Multi-ply EP Conveyor Belt is mainly used in short and medium-distance materials transportation, very suitable for minerals, architecture, ports, road construction, agriculture, steel, and chemical industry, etc.

Characteristics:

1. High stability
2. High heat resistance
3. Low elongation
4. Impact resistance
5. Strong anti-shock
6. Good flexibility

Multi-ply conveyor belt giving the product mechanical features such as low elongation, impact and traction resistance. It is widely suitable for any bulk material handling.
Two rubber covers, named top and bottom covers, which protect the resistant carcass and characterize the belt. In order to guarantee safety and long life, also under hard working conditions, all type of rubber covers are antistatic and ozone protected.

Production Process

The rubber conveyor belts may generally be produced in 5 steps.

Mixing → Calendaring →Laminating → Vulcanising - Inspecting/packing
1. The initial phase of the production process is to mix the rubber.
2. The calendering process mainly completes the fabric coating, cover sheeting, and bonding of the belt carcass and the covering sheet.
3. Laminating is the process of neatly adhering multiple layers of the belt together longitudinally, sticking edge rubber on both sides, and covering rubber on the top and bottom to make a belt blank.
4. Rubber vulcanization is one of the most important procedures in the processing of rubber conveyor belts, as well as the final step in the manufacturing process.
5. Finished belt after testing.

Application

 
Our belt is mainly used in all the process industries to carry different materials, for example:

1. Fertilizer Plants - Superphosphate in lump and powder
2. Cement Plants - limestone, Clay slacked lime, sand, Cold clinker
3. Steel & Power Plant -Coal, Coke, ashes, and crushed metallic ores
4. Stone Crushing Industries - Granite & Blue metal, crushed stone
5. Biomass Power Plant - biomass fuels, wood chips, paper bales, gravel, sized coke
6. Glass Industries - timber crushed glass, granite, all types of slacks, sandstones, chipping, quartz, and re-claimers.
