Belt Drive Conveyor Backstops
Location For Backstop Installations. 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. This provides the most positive means of controlling belt reversal.

6.7: Belt Friction
In other cases such as a belt-driven system, these friction forces are put to use transferring power from one pulley to another pulley. Figure 6.7. 1: In many belt-driven systems, the belt friction keeps the pulley from slipping relative to the belt. This allows us to use belts to transfer forces from one pulley to another pulley.

Q.5. The width of the conveyor belt is 1400 mm, and the angle of surcharge of grain is 25°. Estimate the cross-sectional area of grains on the belt, if single roller belt conveyor is used. Answer: The width of belt is less than 2 m, therefore: B = 1400 mm = 1.40 m b = 0.9 B − 0.05 = 0.9 × 1.4 − 0.05 = 1.21 m

What is Conveyor System? Types, Parts, Working, Uses [PDF]
Belt support; Pulley system; Drive unit; 1. Belt Support. Belt support is a component of a conveyor system that allows the belt to move smoothly without any restrictions. If the support unit is not stable, the belt fails if there is a heavy object on top of it, and this causes the belt to not move as smoothly or as fast as it should.
