Design of conveyor belt

The design scheme of the conveyor belt is determined by the equipment situation and the performance, form, and environmental conditions of the materials to be conveyed. Good design can not only ensure the use performance of the conveyor belt, extend the service life, but also reduce the manufacturing cost. Before designing, you should first understand the type, quality, and form of the material being conveyed, as well as the loading drop, conveying volume, flow-form, and conveying route and distance as the basic reference point of the design. The design content roughly includes structure, strength and safety factor, belt width and configuration, covering rubber, and cross reinforcement.

Rubber conveyor belt manufacturing process

The basic manufacturing process of rubber conveyor belts includes rubber compounding and processing, calendaring, extrusion, molding, vulcanization, and inspection/packing.

(1) Process performance of rubber compound. The scorch performance, stickiness, and plasticity of the rubber compound will affect the preheating and calendering of the rubber compound. The temperature control and the rubber throughput need to be balanced, and the preheating capacity and the calendering ability need to be matched. Too high temperature or too much rubber will cause the rubber to accumulate and cause scorching. On the contrary, insufficient skimming will happen.

(2) Roller temperature Accurate temperature control is the basic condition for the normal operation of heat smelters, extruders, and calenders. The control program provided on the calendar should ensure that the equipment maintains the best temperature during operation.

(3) Tention The purpose of controlling the pretensioning force of the fabric is to ensure the strength of the finished conveyor belt and also to prevent the fabric from being damaged due to slack when the fabric passes through the gap between the rollers. The pre-tensioning force of the fabric is about 2% to 3% of its breaking strength.

(4) Thickness control is important for preventing waste and excessive rubber consumption. Automatic control must be reliable. If it is unreliable, it will be very dangerous.
