Drum Conveyor Pulley for Stone Plants

drum-conveyor-pulley-1

According to the structure style, the two types of the pulley can be divided into three light duty, medium duty, and heavy duty.
All the pulleys adopt integrated bearing housing which is lubricated and filled with grease and has two kinds: Iron casting and steel casting, the shaft is made of 45#steel, and the shell adopts weld assembly.
Based on the above design, the pulley is reasonably structured, convenient type selected, performance reliable, and has a long lifetime.
Applications: Used in the steel industry, harbor, coal industry, power industry, cement industry, and more.

Drum Conveyor Pulley Featureļ¼š

Key Features of conveyor pulleys:
1. Steady running, reliable quality, and reduced maintenance;
2. Less movement longitudinally, rotating smoothly, extends the life span;
3. Various bearing housing and sealing structures are available for the customer’s choice;
4. Multipass labyrinthine sealing, preventing the mixed dirt and water from being immersed;
5. Manufacturing by steel pipe specially for high precision roller, ensuring an intense load, low shaking, and less noise.

How To Install The Pulley?

Check pulley slots to make sure there are no scars or sharp edges and all dimensions are up to standard;

Clean surfaces of all components, such as hub holes, cone sleeves, bolt holes, etc. Fit the cone into the pulley so that all screw holes are aligned.

Grease the screws and threads and screw into the mounting holes, but do not tighten them for now.

Clean the surface of the drive shaft, push the tapered pulley to the predetermined position on the shaft, and check whether the V-shaped pulley is aligned.

When the keyway is used, it must be inserted into the shaft hub first, and there must be a certain tolerance between the keyway and the hole hub.

Using a din911 standard Allen wrench, alternately, gradually, and evenly tighten the bolts in each mounting hole until the torque shown in the table below is achieved.

After a short period of operation (0.5 to 1 hour), check the bolt tightening torque, and tighten the bolts if necessary.
Fill the joint of the hole with grease to prevent foreign matter from entering.

Types of Conveyor Pulley:

The drum is the main component that transmits power. It is divided into three types according to their load-carrying capacity: light, medium and heavy.
Light: Bearing aperture 80-100mm, the shaft and hub are single-width plate welded cylinder structure connected by single key.
Medium: Bearing aperture 120-180mm, the shaft and hub are expansion sleeve connection
Heavy: Bearing aperture 200-220mm, the shaft and hub are expansion sleeve connection, and the drum body is cast-welded structure.

Conveyor pulley stays at two ends of belt machine. The pulley can be divided into two categories: Driving pulley and averting pulley, driving pulley is the main part for transmitting the power and there are two kinds of pulley sets: Smooth surface and rubber surface, and rubber surface can be classified into smooth rubber surface, herringbone rubber surface and diamond rubber surface to meet different technical requirements. Averting pulley can be classified into smooth rubber surface and smooth steel surface.
