Product Description

Product Description

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

Hot transported material can very easily damage the conveyor belt, to prevent possible damage, special high-temperature resistance canvas with high modulus, low shrink, and high breaking tensile strength is adopted as carcass, and EPDM Rubber or Chloro butyl rubber by mixing some other high-temperature resistant materials and with advanced technique, the belt made better performance in heat resistance. That not only solves the fabric shrinkage and deformation problems but also avoids crucial poor adhesion problems caused by a high degree of saturation of ethylene propylene rubber The belt is excellent in heat resistance,low elongation light, and with longer use life, etc

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

Fabric Rubber conveyor belt helps to enhance the productivity of various industries by reducing the requirement for manual labor. Moreover, the working conditions and facilities in firms dealing in metals, chemicals, textiles, and mining have also been improved. Consequently, automated systems have made a significant place outside the industries as well. It is widely used in mine transportation, steel delivery, bulk material transportation, coal washing delivery, cement delivery, salt plant delivery, and so on.
