High Quality Conveyor Equipment Manufacturer

Tongxiang is a professional conveyor equipment manufacturer with 38 years of production experience.Today we introduce the classification of conveyor belt.
First, the conveyor belt is widely used in cement, coking, metallurgy, chemical industry, steel and other industries where the delivery distance is shorter and the delivery volume is smaller.
Product structure: This product uses multi-layered glue cotton canvas as the skeleton, the surface covering good performance rubber material, made by vulcanization.
Conveyor belt products include ordinary cotton canvas conveyor belts and nylon (NN) conveyor belts (which are divided into NN-100 type, NN-150 type, NN-200 type, NN-250 type, NN-300 type, NN-350 type, NN-400 type, polyester (EP) belt (Divided into EP-100 type, EP-150 type, EP-200 type, EP-250 type, EP-300 type, EP-350 type, EP-400 type) , Large dip (corrugated ribs) conveyor belts, skirt separator conveyor belts, endless conveyor belts, pattern conveyor belts. Because of the different conveying materials and the different conveying inclination angles, the pattern shape and height are also required to be different. Commonly used patterns of conveyor belts such as: herringbone pattern conveyor belt (herniform conveyor belt includes convex, concave concave herringbone conveyor belt), eight-shaped pattern conveyor belt, fish bone pattern conveyor belt, U-shaped pattern conveyor belt, cylindrical Pattern conveyor belt, dot pattern conveyor belt, etc., or designed according to user requirements}, water stop, PVC or PVG flame retardant core, etc.; and can provide a variety of special properties of the conveyor belt (general flame retardant conveyor belt, resistance Heat conveyor belts, burn-resistant conveyor belts, highly wear-resistant conveyor belts, acid-resistant conveyor belts, alkali-resistant conveyor belts, cold-resistant conveyor belts, oil-resistant conveyor belts, high-temperature conveyor belts, high-strength conveyor belts, and food conveyor belts).

Second, the conveyor belt is divided into many specifications and models depending on the use of the environment and the requirements:
1. According to the size of traffic divided by width: B200 B300 B400 B500 B600 B650 B800 B1000 B1200 B1400 B1600B1800 B2000 and other common models (B stands for wide Degree in millimeters).
2. According to the use of different environments, divided into ordinary conveyor belt includes (common type, heat-resistant, flame-retardant, burning-resistant type, acid and alkali resistant, oil-resistant), heat-resistant conveyor belt, cold-resistant conveyor belt, acid resistance
Alkaline conveyor belt, oil conveyor belt, food conveyor belt and other models. The minimum thickness of the cover rubber on ordinary conveyor belts and food conveyor belts is 3.0mm, and the minimum width of the lower cover rubber is 1.5mm. The minimum thickness of the cover tape for the tape feeding, cold-resistant conveyor belts, acid and alkali-resistant conveyor belts, and oil-resistant conveyor belts is 4.5 mm, and the minimum width of the underlay rubber is 2.0 mm. According to the specific circumstances of the use of the environment, press 1.5mm to increase the thickness of the upper and lower cover rubber.
3. According to the strength of the conveyor belt fabrics, it is divided into ordinary conveyor belts and powerful conveyor belts. Strong canvas belt is divided into nylon conveyor belt (NN conveyor belt) and polyester conveyor belt (EP conveyor band).
(1) Ordinary conveyor belts (including high-strength nylon conveyor belts) implement the GB7984-2001 standard.
Ordinary conveyor belt:Cover layer: tensile strength of not less than 15Mpa, elongation at break of not less than 350%, abrasion amount of ≤200mm3, interlayer adhesive strength of longitudinal specimens between the average cloth layer not less than 3.2N/mm, covering the gap between the rubber and fabric Not less than 2.1 N/mm
Full thickness longitudinal tear elongation of not less than 10%, full thickness longitudinal reference force elongation of not more than 1.5% Nylon (NN), Polyester (EP) Conveyor Belts:
Covering layer: tensile strength not less than 15Mpa, tearing elongation not less than 350%, wear volume ≤ 200mm3 Interlayer Adhesion Strength The average length of longitudinal specimens shall not be less than 4.5 N/mm between layers, and not less than 3.2 N/mm between overlay rubber and fabric layers.
Full-thickness longitudinal elongation at break of not less than 10%, full thickness longitudinal reference force elongation of not more than 4%
(2) Three-resistance conveyor belt (heat-resistance, acid-resistance, alkali-resistance) The product implements the HG2297-92 standard.
(3) Flame-retardant conveyor belt The product implements the MT147-95 standard.
