Talk about food security equipment accessories

Food security equipment accessories, including roller, belt conveyor idler is an important component of many kinds of large quantities which accounted for a total cost of 35% of

the belt conveyor idlers , bear more banana screen than 70% of the resistance , Therefore, the quality of the roller is particularly important .
The role is to support the roller conveyor and material weight roller operation must be flexible and reliable. Reduce friction roller conveyor with the accounting for 25% of the

total cost of the conveyor belt over screen machinery the life plays a key role , although care roller conveyor is a small part , the structure does not re-

Complex, but the manufacturing of high-quality roller is not easy.
Determine quality standards idlers were the following : radial runout roller , roller flexibility , axial runout .
Food security equipment accessories belt knowledge to explain performance
    Called conveyor belt conveyor belt conveyor is used to play the role of carrying and transportation of materials rubber and fiber, metal composite products , or a composite

of plastic and fabric products. Conveyor belt is pulled cited and bearing material master component , the choice of a reasonable size when used under the tension of cotton

canvas

, Polyester canvas or nylon canvas belt . Belt cover layer has a unified standard , the following for ordinary conveyor belts and nylon conveyor belt cover layer do a brief

introduction :
      Belt cover layer HG2297-92 Standard: nylon conveyor belt cover layer tensile strength maintained at more than 15Mpa , tearing stretched length remains at 350 % or more,

the amount of wear is less than 200mm3, interlayer adhesion strength fabric layers longitudinal sample average is greater than 4.5N/mm, plastic and cloth covering layer

Is greater than 3.2 N / mm full- thickness longitudinal elongation greater than 10% , full thickness longitudinal reference force elongation is less than 4% (2) three -resistant

conveyor belt ( heat, acid , alkali )
      General conveyor belt cover layer GB7984-2001 standard : general conveyor belt cover layer tensile strength maintained at more than 15Mpa , tearing stretched length

remains at 350 % or more, wear less than 200mm3, interlayer adhesion strength longitudinal sample average cloth layer is greater than 3.2N/mm, covering

Rubber and fabric layers is greater than 2.1 N / mm full thickness of the longitudinal elongation at break of not less than 10 % full thickness longitudinal reference force

elongation is less than 1.5%
