What is drive pulley in conveyor belt?
A Drive Pulley or Head Pulley is used for the purpose of driving a conveyor belt. They are normally mounted in external type bearings and driven by a motor and reducer. Conveyor head pulleys can be flat faced or crowned and many have lagging to reduce belt slippage.
What are the different types of pulleys in a belt conveyor?
Different kinds of conveyor pulleys
- Head pulleys. The head pulley is located at the discharge point of the conveyor.
- Tail and wing pulleys. The tail pulley is located at the loading end of the belt.
- Snub pulleys.
- Drive pulleys.
- Bend pulleys.
- Take-up pulley.
Do conveyor belts use pulleys?
The conveyor belt forms a closed-loop across the pulleys, which enables continuous movement of the system. Conveyor systems mostly use a rotor to power the belt and drive the pulley.
How do you size a conveyor pulley?
The pulley diameter is mainly determined by the conveyor belt class, but the required shaft diameter also influences the diameter. A golden rule for the pulleys diameter is that it should be at least three times the diameter of the shaft.
What types of pulleys are there?
There are three main types of pulleys: fixed, movable, and compound.
How do you pick a V belt pulley?
Following are some environmental and application design criteria that will influence belt selection:
- Ambient temperature.
- Oil resistance.
- Ozone resistance.
- Static conductivity.
- Power capacity.
- Pulsation or shock loading.
- Small sheave diameters.
- Backside idlers.
What is a snub pulley used for?
Snub pulleys are used to increase the wrap angle of the conveyor belt to reduce the pulling force of the belt. Snub pulleys can therefore optimise the cost of your conveying system, since they reduce the belt tension which means that a conveyor belt with a lower belt strength can be used for the same purpose.
Which rubber is used in conveyor belt?
Grade M & N – General Purpose. General-purpose rubber is the most common type of rubber conveyor belt and is used when special properties are not needed to suit an application. Grade N rubber is lower quality compared to Grade M.
Do conveyor belts retain their value?
Portable conveyor belts usually have the highest residual value because they can be used anywhere without technical modification. They are also easy to obtain second-hand. Fixed conveyor belts can often be dismantled and reassembled in a different place, although this affects their residual value.
What is the face width of a pulley?
The face length of a conveyor pulley is a derivative of the conveyor belt width. In bulk handling applications, an adequate pulley face length is one that is 2” or 3” greater overall or 1” to 1.5” greater on each end than the overall width of the conveyor belt.
What type of pulley is a well?
Fixed Pulley For example, when attached to a bucket pulling water from a well, a fixed pulled allows you to pull laterally to raise the bucket in a more convenient manner than if you were hauling a bucket of water up vertically, hand over hand.
