Drum liners

Drum liners

ФLining of belt conveyor drive drums
is a coating of the drum shell using special materials such as rubber liners with tread, ceramic liners, a combination of rubber and ceramic, polyurethane and other similar materials. This coating improves the grip of the drum on the conveyor belt.

Types of materials used

What is the purpose of drum liners?

Lining of conveyor drums helps to increase the traction force on the drive drum, significantly extends the service life of the conveyor belt, preventing its slippage in waterlogged conditions, as well as helps to maintain the straightness of the belt and increase the productivity of the conveyor.

Ceramic lining of belt conveyor drums

Product Description:

The abrasion-resistant ceramic elements based on 92-95% alumina can be arranged in the required geometry and fixed with epoxy-based adhesives. The special geometry of the ceramic elements prevents the conveyor belt from slipping during operation.

Material Characteristics

Alumina elements have high wear resistance, hardness, heat resistance, inertness to aggressive media, is not subject to corrosion. The use of this type of lining eliminates conveyor slippage, increases the service life and productivity of the equipment, reduces operating costs. There is no need to increase the load to maintain adhesion in high humidity conditions. Reduced belt web tension increases belt life.

The ceramic tile teeth have rounded edges to prevent damage to the belt web. Water and dirt drainage from the drum surface and conveyor runability is improved. Can be hosed off without loss of adhesion quality.

Service life of the drive drums:

  • Steel liners average 1 to 3 years depending on operating conditions;
  • Rubber products from 3 to 7 years depending on operating conditions;
  • Ceramics for up to 20 years.

Rubber lining of the drive drum

Information:

Lining rubber plays a key role in ensuring the efficient operation of a variety of technical systems, especially conveyor systems. This special material is used for lining the surfaces of conveyor drums, providing a reliable grip on the conveyed load and protecting the equipment. adhesion to the transported load and provides protection for the equipment.

Features

One of the important features of liner rubber is its profile. For example, rubber with a diamond-shaped profile has a feature in the form of a rhombic pattern on the outside. This pattern promotes a better grip on the conveyor belt and drive drum, which reduces the risk of the load slipping or slipping during transportation.

Designed for operating environment like, coal, mine and port etc.

In addition, the lining rubber has a high degree of wear resistance and resistance to various factors such as moisture, chemicals and mechanical stress. This ensures the longevity of the drum liner and extends the service life of the entire conveyor system.

Rubber-ceramic lining of belt conveyor drums

Product Description:

Rubber-ceramic lining provides long drum life, eliminates belt slippage, reduces downtime, increases liner and drum life in conditions of high pollution and dampness.

Characteristics

Rubber-ceramic drive drum liners are particularly suitable where slippage and excessive wear make conventional rubber liners ineffective. Alumina ceramic elements help to keep the belt in the correct position even in conditions of high humidity, heavy soiling and abrasion. In addition, by varying the thickness of the ceramic elements and the overall thickness of the liner, differences in drum diameters can be compensated for.

NOTE!

This type of lining is most effective in the temperature range of -30°C/+70°C.

Appearance

Removable lining of belt conveyor drums

Product Description:

Removable liner plates for the drive drum Slide-Lag and Bolt-On are quick and easy to remove and install, great for drums installed in hard-to-reach areas where removal is very difficult due to drive train, baffles or height of location.

Material Characteristics

The removable liner plates are made of special wear-resistant rubber, fully vulcanized under high pressure on a steel frame that is pre-bent to match the drum diameter. This neutralizes internal stresses in the liner and gives maximum rubber-to-metal bonding strength. The use of high density rubbers, ensures a long service life. The retaining strips are also made of steel, so the installed linings are firmly fixed to the drum surface. The removable liner can also be made with ceramic elements instead of the diamond pattern.

Lining fastening methods

Removable liner

Description:

The method of attachment of removable liners plays a key role in the durability and effectiveness of conveyor drum protection. One method involves the use of specialized fasteners, such as bolts or clamps, that provide a strong and secure connection between the liner and the drum surface. This approach ensures the stability of the liner even under high loads and provides easy installation and replacement of the elements.

On the glue

Description:

The adhesive liner fixing method is an effective alternative, especially when working with ceramic elements. The use of specialized adhesives ensures a strong and uniform bond between the liner and the drum surface, minimizing the risk of delamination or fracture of the elements. This method also provides ease of installation and maintenance, making it a popular choice for a variety of industries that require reliable protection of conveyor systems from wear and damage.
