Classification according to the product structure

Classification according to the product structure: Layered conveyor belt, cement mixing machine, steel cord conveyor belt, steel cable conveyor belt, pipe conveyor belt, pattern conveyor belt, sidewall conveyor belt, conveyor belt layer reduction.
For convenience, we usually adopt a unified representation for various conveyor belt various categories of representation
1, layered conveyor common representation (standard notation Unlike this, please refer to the specific provisions of the standard GB7984):
In NN200 1000 × 6 (6 +3) as an example, NN200 represents the nylon 200, 1000 - indicates the width of the tape 6 - indicates nylon layers, (6 +3) - indicates the upper and Cement silo rubber conveyor belt were 6 mm and 3 mm thick.
2, steel cord conveyor belt commonly used representation:
In ST1000 H 1000? 4.0-6.0-6.0 as an example:
ST1000-represents the strength specifications for 1000N/mm
H-indicates the level of performance plastic cover
1000 - represents the width of the product, in mm
? 4.0-represents the rope diameter in mm
6.0-6.0-represents the upper and lower plastic cover thickness in mm
3, the representation of the entire conveyor belt
General mine with PVC and PVG whole core fire-retardant conveyor belt with intensity levels and tape width to represent. Intensity level is generally divided into: 4, 5, 6, 7, 8, 9, 10, 11, and up to 16 bands. Conveyor belt width is generally: 500mm, 650mm, 800mm, 1000mm, 1200mm, 1400mm, 1600mm, 1800mm and so on.
China provides that all coal mine conveyor belt products used must comply with the relevant standards of the flame-retardant anti-static conveyor belt. Commonly used conveyor coal mining enterprises are: PVC whole flame retardant antistatic conveyor belt, PVG whole core fire-retardant anti-static conveyor belt, steel cord conveyor belt fire-retardant antistatic.
Retardant antistatic conveyor main provisions of the product's safety performance: an alcohol burner combustion; 2, the surface resistance; 3, roller friction; 4, simulated roadway propane burner. These test items characterize the product's safety performance.
