Selection of lining plates and material requirements for shaftless screw conveyors

Shaftless screw conveyor; Is the blade in direct contact with the casing, with or without an axis? No, it is usually divided by lining plates.

What materials can be used for the lining plate of a shaftless spiral conveyor?

The lining plate of the shaftless screw conveyor can be made of the following materials:

One option is to use nylon or polyethylene, which has the advantage of being good, but has temperature requirements and cannot exceed 60 degrees. Manganese steel can be used, all aspects are very good. Thirdly, it is stainless steel, and the material temperature requirement is. Within 350 degrees, it is also suitable for food materials.

2. Shaftless screw conveyor; What lightweight and heavy-duty materials can be transported, and what are the requirements for slag adhesion?

(1) Alum, aluminum sulfate, baking soda, with good flow, lightly ground powdery and fine-grained materials. (Sodium bicarbonate), wheat, bauxite powder (dry), castor beans (whole grain with shell), borax (fine grain), coffee (roasted beans), corn, seeds (dry, dust removed), clay (burnt), crushed stone powder.

(2) Powdery and fine-grained materials, good, lightly ground: foxtail millet, oats, fertilizer, rice (dehulled), rice, starch, urea (small particles), wheat, rye, graphite flakes, black beans.

(3) Generally, the flowability is poor, and there is slight grinding of powdery and fine-grained materials; And lightly ground granular and block materials: fine alum, calcium hydroxide, barley flour (sprouts), bone meal, calcium carbide, coal, corn starch, cottonseed (dry, dust-free), fish meal.

(4) Generally poor, lightly ground powdery and fine-grained materials, as well as lightly ground granular and block materials: flour, gypsum powder, (roasted), red lead (fine powder), quicklime powder, hydrated lime powder, oat flour, peanut kernels, potato flour, rubber powder, (granules), soap flakes (soap granules), soybean powder, sawdust powder.

(5) Medium grinding materials: cement, coal slag, cryolite, diatomaceous earth, fly ash, coal ash, iron oxide, limestone powder, peanuts (shell, unwashed), sesame, soybeans, loose coal, bauxite, alumina, asbestos ore.

(6) Large abrasives: alumina, asbestos (ore), basalt powder, glass (raw material), granite, Dalian stone (crushed), quartz sand powder, slag (dry, granular).
