product description:
Drum rubber inserts are widely used in the head wheels of various bucket elevators, large coal mines, steel mills, cement plants, and belt conveyor drive drums in ports. It replaces the traditional thermal vulcanization rubber roll, and the cold-adhesive rubber cover. Easy and quick maintenance construction, reducing downtime.

Features:

Large transmission friction: The unique product surface texture design of the rubber-coated insert (the perfect combination of prismatic grooves and Z-shaped grooves) can enhance the transmission force and friction to avoid the problem of roller slippage.
2. Long service life: High elastic and wear-resistant rubber material is used to extend the service life of the drum.
3. Installation and maintenance are simple and convenient: the rubber-covered inserts are installed, and the drum does not need to be disassembled. The site is temporarily stopped. Loosen the belt to allow the drum to rotate. Improve efficiency and reduce use costs.
4. The product has a wide range of applications: according to the actual application requirements, it can meet the needs of various indexes such as cold resistance, high temperature resistance, antistatic, antiflammability, and non-toxicity.
5. Tailor-made: tailor-made according to the diameters of different specifications and types of rollers to meet the product needs of various customers.

Product structure:

1. Abrasion-resistant rubber pattern surface: It adopts high-abrasion rubber material and unique surface texture design to improve the friction of the roller to obtain stronger traction to assist the belt running.
2. The steel plate and rubber plate are bonded at one time by high pressure vulcanization process to ensure the stability of the bonding of the two materials.
3. According to the diameter of the roller, the inserts have various radians at the factory to ensure the perfect fit between the insert and the roller. Guarantee long-term stability.
4. The metal bar is welded to the surface of the roller to ensure that the rubberized insert is fixed on the surface of the roller.

Specifications:
1. The standard rubber-coated steel sheet is a 2mm thick cold-rolled steel sheet with a rubber surface of 13mm and a total thickness of 15mm. a) The high wear-resistant rubber-insulated insert steel plate is a 2mm thick cold-rolled plate with a rubber surface of 16mm and a total thickness of 18mm.
2. The standard width of the plastic insert is 138mm, and the maximum length of a single piece is 1830mm. The length can be cut according to the actual size.
3. The calculated width of the bar is 20mm, thickness 2.5mm, 3.0mm.
4. Calculation of product specifications: roller diameter × 3.14 ÷ 160 = number of rows of combined plastic inserts used (unit: mm).

product type:
1. Standard type: wear-resistant lagging material for ordinary conveying and lifting capacity and normal running speed;
2. High abrasion-resistant type: High-wear-resistant cladding material required for large conveying capacity, large lifting capacity, and fast running speed;
3. Flame retarding type: for coal mine conveyors, flame retardant abrasion-resistant cladding materials that meet the safety requirements of coal mines;

Roller Rubber Insert Installation Manual

installation steps:
1. Clean the surface of the roller and smooth the uneven surface.
2. Place the bar on the roller horizontally, and make sure it is parallel, then clamp the two ends of the bar on the roller with strong forceps.

3. Make sure the bar is flat and weld the plug hole.
4. Lay the plastic inserts flush with the raised wings of the bar, and use strong pliers to clamp the plastic inserts.
5. Place another stopper, allow 1mm back space, and fix it with strong forceps.
6. Confirm the flatness, as shown in the spot welding, and then weld the remaining plug holes after welding.

7. Repeat the above steps until the last plastic insert.

8. If the installation is just completed, if the remaining space is large, use a measuring tool to measure the distance, use a cutting machine and a tool knife to cut the rubber sheet to a suitable size, and use the stopper to fix the last piece.

Precautions:
1. When cutting the rubber insert, the cutting piece should be cut from the steel plate surface, and then the rubber part should be divided with a tool knife to prevent the cutting piece from overheating and damaging the rubber.
2. A single bar should be spot-welded multiple times. The welding time of each welding hole should not be less than three seconds (to prevent the rubber in the welding area from being exposed to high temperature for too long).
3. Arrange welding work reasonably according to the construction environment.
