Materials of the Conveying Disc The disc material is selected differently for different working conditions. The common types are as follows:Engineering plastics: The most commonly used.

Including nylon (PA66) POM (polyoxymethylene) and ultra-high molecular weight polyethylene. Wear-resistant, self-lubricating, lightweight, corrosion-resistant, and quiet.

For industries such as food and chemicals that require high material purity. Low coefficient of friction, low running resistance, little damage to the pipe wall, and a relatively low cost.

Metallic materials: Such as high-strength alloy steel, 304 stainless steel, or carbon steel. High hardness, strong load-bearing capacity, and high temperature resistance.

For conveying heavy or high-temperature materials such as ores and building materials. Surface hardness up to HRC45–50, with better wear resistance than ordinary carbon steel, but a relatively high weight.

Composite materials: In some special applications modified plastics with a wear-resistant coating are used to balance toughness and wear resistance.

Selection Criteria.

Material characteristics: For corrosive materials, choose acid- and alkali-resistant plastics or stainless steel.

For fragile materials, choose smooth-surfaced nylon discs; and for heavy materials, choose high-strength alloy steel.

Conveying conditions: Lightweight, low-resistance nylon discs are preferred for long-distance or multi-turn routes.

In high-temperature environments, heat-resistant modified materials should be selected.
