What is lagging on a pulley?
Conveyor pulley lagging is an essential part of a belt conveyor system, protecting the pulley and ensuring that there is proper friction between the pulley and the conveyor belt. When a pulley is not properly lagged, you can experience belt slippage and even increased belt wear.
What is lagging in conveyor?
Pulley lagging is the layer of material which is bonded to the shell of a conveyor pulley. Its function is to protect the shell from damage, increase friction with the conveyor belt and dispense water off the pulley.
Is standard for pulley lagging?
9.1 The lagging shall be of rubber and it shall be vulcanised on to the pulley. The rubber shall be of 60 5 shore – A hardness and 17 MPa (minimum) tensile strength and 400 percent (minimum) &longation at break.
What is a rubber lag?
Vulcanized rubber lagging is 45/60/70 durometer Shore A, S.B.R. black rubber without a cloth fabric. It is bonded directly to the pulley rim in the vulcanizing process. The finished rubber surface has a cloth impression. Normally, grooving should not be used in vulcanized rubber less than 3/8″ thick.
What is the pulley lagging worn solution?
Drive & Non-Drive Rubber Lagging Drive and Non-Drive Pulley Lagging is the solution, in an application where rubber is the answer, to help eliminate slippage, increase pulley life and to improve production.
How many types of conveyor pulleys are there?
4 Types of Conveyor Pulleys.
What is pulley face width?
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 are some different types of pulleys?
6 Different Types of Pulleys (And When to Use Them)
- Fixed Pulleys. Fixed pulleys are the most common type of pulleys, and the most simple, for that matter.
- Moveable Pulleys. Moveable pulleys are the exact opposite of fixed pulleys.
- Compound Pulleys.
- Block and Tackle Pulleys.
- Conveyor Pulleys.
- Cone Pulleys.
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.
What are the types of conveyor pulley lagging?
Rubber is the most common type of pulley lagging as it is one of the most affordable conveyor component options. Rubber is a versatile material that varies in thickness, hardness and type of grooves. The two main types of rubber lagging are: • Plain Rubber Lagging for non-drive pulleys to provide better traction for the conveyor belt.
What are the different types of pulleys?
There are several different types of pulley lagging, such as plain rubber, grooved rubber and ceramic lagging. Each type of pulley lagging has different variations, specifications and are used for a variety of purposes.
Is it good to use rubber lagging on pulleys?
Belt slippage can still occur even though rubber lagging increases friction to the conveyor belt. Rubber lagging is not the most optimal pulley lagging product to achieve high levels of friction.
How is ceramic lagging applied to a pulley shell?
Ceramic lagging can be applied to the pulley shell as a rubber backed ceramic strip or sheet. The rubber backing is bonded to the pulley shell. The other method is to directly bond the ceramic tiles to the pulley shell. There are a few issues with ceramic lagging. Ceramic can be fragile and prone to cracking.
