Primary belt cleaner is installed on the surface of the head pulley belt, below the material drop track, to allow the material to detach smoothly from the belt. 一级清扫器安装在头部滚筒输送带表面,在物料下落轨迹的下方,使物料顺利与皮带脱离。

Trough rollers are the components used to support belt and material loaded on the belt conveyor. The standard trough angles are generally divided into 10°, 20 °, 30 °, 35 ° and 45 °. 槽型托辊组是用来支撑输送带及输送带上承载物料的部件，标准槽角一般分为10°、20°、30°、35°、45°.

Drum Pulleys are designed to meet CEMA Construction standard,Lagged Crown Faced Head/Tail Pulleys with taperlock bushings.

Wing pulley incorporate a non-continuous contact surface comprised of individual wings or fins. Also known as self-cleaning pulley, wing pulley is primarily used on the tail end of bulk handling system . This construction results in the creation of open voids that allow loose material to fall away from the contact surface. 翼形滚筒包含由单个翼片组成的非连续接触面，也称为自清洁滚筒，翼形滚筒主要用于散装处理系统的尾端。 这种结构会产生开放空隙，使松散物料从接触表面脱落。
