Quick Replaceable Pulley Lagging

Introduction：

Pulley lagging is widely used in the head wheels of bucket elevators, the driving rollers of belt conveyors in large coal mines, steel mills, cement plants and ports. It can replace the traditional hot vulcanization encapsulation roller, and the cold adhesive encapsulation method. Maintenance and construction are convenient and quick, and downtime can be reduced.

Replaceable Pulley Lagging Construction:

Rubber lagging is hot vulcanized on Q235 steel plate in our factory.

Diamond groove, plain, ceramic surface or as your request.

Exclusive rubber compounding provides a lagging pad with exceptional drive-pulley traction, abuse resistance and extra long service life. 

Technical Data:

1. Rubber
1.1 Material: NR or Flame Rretardant Rubber
1.2 Hardness: 65±5 Shore A
1.3 Abrasion Loss: ≤80 mm³ 

2. Steel Plate Backing Plate
2.1 Material: Q235
2.2 Thickness: 2~2.5mm
2.3 Width: 138±0.3mm

3. Overall Thickness: 15mm, 18mm, or as Client's Request.

Characteristics:

1. High transmission friction: the unique surface texture design(perfect combination of prismatic groove and Z-shaped groove) can enhance the transmission force and friction and avoid the slipping problem.

2. Long service life: the use of highly elastic and wear-resistant rubber materials extends the service life of the roller.

3. Easy and convenient installation and maintenance: no need to disassemble the roller during installing the rubber coated insert; has short  downtime; loose the belt to ensure the roller can operate normally; install the metal strips, insert the pulley lagging; fasten and reduce downtime; improve effiency; reduce the cost.

4. Wide range of applications: according to actual application requirements, it can meet various needs, such as cold resistance, high temperature resistance, antistatic, flame retardant, and non-toxic, etc.

5. Tailor-made: Custom-made according to the diameter of the rollers of different specifications and models to meet the product needs of various customers.

1. Wear-resistant rubber pattern surface: using high wear-resistant rubber material, and its unique surface texture design improves the friction of the roller to obtain stronger traction to assist belt operation.

2. The steel plate and rubber plate are bonded and molded at one time by high-pressure vulcanization process to ensure the bonding stability of the two materials.

3. According to the diameter of the roller, there're various radians inserts to ensure the perfect fit between the inserts and the drum. Ensure the stability of long-term operation.

4. The steel strip is welded on the surface of the roller to ensure that the rubber-coated insert is fixed on the surface of the roller.

Product Specification:

1. Standard rubber coated insert: the thickness of the cold-rolled steel plate is 2mm, the thickness of the rubber plate is 13mm, and total thickness is 15mm.

A. The wear-resistant rubber coated insert used is the cold-rolled steel plate with 2mm thickness, the thickness of the rubber plate is 16mm, and the total thickness is 18mm.

2. The standard width of the rubber insert is 138mm. The maximum length of single piece is 1830mm, and can be cut according to actual size needed.

3. The width of steel strip is 20mm, thickness is 2.5mm.

4.Product specification calculation: Roller diameter×3.14÷160=Row of rubber coated inserts (Unite: mm).

Product Type:

1. Standard type

2. High wear resistance type

3. Flame-retardant type

Number of Lagging Used Calculation:

Calculation method(Standard length of lagging is 1830mm）:

Eg：800 dia.×1000 width

       800*3.14/160=16 row insert

       16*1000/1830=8.8 or9 pcs(the number of pulley lagging need)
