The structure of drive pulley and bend pulley should be chosen according to the bearing force of pulleys. The surface type selection of pulleys should meet the following requirements:
1. According to the peripheral force of transmission and working conditions.
1) Rubber surface drive pulley is used on the condition of big peripheral force , poor working conditions and low ambient temperature.
2) Smooth surface drive pulley can be adopted by small belt conveyor, which has small peripheral force and better working conditions.
2. Rubber surface drive pulley is divided into two patterns, chevron and diamond grooves.
3. Rubber surface bend pulley is used on the condition of poor working conditions and contact with conveyor belt carrying surface.
4. The rubber surface performance of drive pulley and bend pulley, which are used in underground coal mine or cold place, should meet the requirements of working environment.
