The coefficient of friction between the belt and the pulley depends upon the following factors: The speed of belt. According to C.G. Barth, the coefficient of friction (μ) for oak tanned leather belts on cast iron pulley, at the point of slipping, is given by the following relation, i.e. where, v = Speed of the belt in meters per minute.

A low-speed backstop generally refers to units that are running at conveyor drive pulley speeds. Most frequently, low-speed backstops are mounted directly on the extended head pulley or drive pulley shaft opposite the drive, as shown in Fig. 3.

Rotary coolers work by tumbling material in a rotating drum in the presence of chilled or ambient air. The drum is set at a slight horizontal slope to allow gravity to assist in moving material through the drum. Lifting flights maximize heat transfer efficiency by lifting up material and dropping it through the chilled air as the drum rotates.
