Alumina Ceramic Rubber Liner

What is the Ceramic rubber composite plate ?

Ceramic rubber composite plate is a composite wear-resistant ceramic rubber plate made by vulcanizing square or hemispherical wear-resistant ceramic lining with rubber using advanced hot vulcanization process.


Alumina Ceramic Rubber Liner combines the advantages of high hardness of ceramic and high cushioning and fatigue resistance of rubber, and can well solve the problem of equipm-ent wear prevention in the process of conveying large pieces of boring. The addition of rubber not only makes the composite plate have good wear resistance and corrosion resistance, but also prevents production stoppage caused by material accumulation and reduces noise.

Types of Ceramic Rubber Composite Liner?

Ceramic rubber composite panels are divided into two-in-one and three-in-one. 

Two-in-one refers to ceramic-rubber composite panels or ceramic -steel composite panels .

Three-in-one refers to ceramic-rubber-steel composite panels. Three-in-one composite panels come with bolts for easy installation.

The  production process of Rubber Backed Alumina Ceramic Liner

Two-in-one: vulcanize the square wear-resistant ceramic lining into the special rubber to form a wear-resistant ceramic rubber composite plate, and then use a special adhesive to bond the composite plate to the inner shell steel plate of the equipment to form a strong and buffering anti-wear layer.


Three-in-one: vulcanize the square or cylindrical wear-resistant ceramic into the rubber, and then use imported adhesives to bond the steel plate together to form a ceramic-rubber-steel composite wear-resistant ceramic rubber composite plate.


Detailed description of product structure

1 ceramic layer

The ceramic layer is mainly made of alumina or ZTA ceramics. It is made of high-quality powder and calcined at high temperature to form special corundum ceramics with a hardness of HRA82 or above. At the same time, according to different working conditions, the production formula and process are adjusted to make the ceramics have certain impact resistance or other characteristics on the basis of high hardness and high wear resistance.

2 Rubber layer

The rubber layer is made of natural rubber with excellent elasticity. Through a special hot vulcanization process, ceramics and rubber are compounded into the steel plate groove under appropriate pressure, temperature and time. The rubber layer can absorb the impact force from the material to a great extent.

Advantage of Alumina Ceramic Rubber Liner

1. Impact resistance, wear resistance: rubber has good cushioning properties, can effectively cushion the impact of ore and other falling from a height, and can reduce the noise generated by the material transport.

Wear-resistant ceramic liner due to the main raw material of the product is alumina, the hardness reaches HRA85 or more, has a very good wear resistance.

2. Acid and alkali resistance: ceramic itself is chemically stable, acid and alkali resistance. The rubber adopts the new formula of acid and alkali resistant rubber, which can resist weak acid and alkali.

3. Non-staining and non-blocking: Due to the high strength and corrosion resistance of the smooth ceramic surface, it effectively solves the phenomenon of equipment staining and blocking. The traditional nylon plate is often stained material, affecting work efficiency;

4. Alumina Ceramic Rubber Liner density is lower than steel, light weight, easy to replace. And because of its wear-resistant, do not need to be replaced frequently, for enterprises to save a lot of time and cost!

5. Anti-shedding: ceramic rubber steel plate is vulcanised as a whole, the combination is very strong; each liner has penetrating bolts through the bottom steel plate, which is firmly welded, double insurance.

6. Convenient installation and replacement: the whole liner is supplied in one piece, which is convenient for replacement and installation and reduces after-sales service.

7. High temperature resistance: it can be operated at 0℃-100℃ for a long time.

Installation method of composite plate

Two-in-one:

1. Use high-strength organic adhesive to bond the composite board to the equipment steel plate.

2. Some customers asked us to add a UV layer on the rubber so that it can be directly torn and bonded to the equipment.

Three-in-one

1 Use high-strength organic adhesive to bond the composite board to the equipment steel plate.

2 Weld the composite board to the equipment

3 Composite boards with bolts can be fixed with bolts
