The rubber coated roller is to cast the barrel of the roller according to the material production needs of different manufacturers when the roller is coated with rubber. The rubber coated roller is mainly divided into cold vulcanization and hot vulcanization, which is commonly referred to as cold gluing and hot gluing. Hot glue coating is to wrap a complete layer of rubber around the roller evenly, and the roller made of hot-dip adhesive casting rubber has a good effect in production. Rubber coated roller

However, the production and processing cost of hot adhesive coating is very high. In the production site, when the rubber surface of the drum is worn, the conveyor bolt will be exposed, which will damage the belt, and it is difficult to repair the rubber surface immediately. The production process of hot-dip adhesive is complex, not only the maintenance time is long, but also the labor intensity and difficulty of production are very large, and the requirements of production personnel are also very high, so it is difficult to meet the needs of mass production of production enterprises.
The cold vulcanized casting rubber is exposed between the upper and lower belts of the driving drum. The selected rubber compound is pasted uniformly on the surface of the drum with the strong adhesive of normal temperature curing type, so as to increase the friction force between the belt and the roller. Polyurethane roller

The roller made of cold vulcanized cast rubber saves the heavy work of dismantling the drum and belt, and the production process is simple, which saves labor and labor in the production. It not only has low production cost, but also has good effect in production. If the rubber surface of the roller is damaged or worn during production, the roller can be repaired on site. At present, the cold glue coating process is widely used, so choosing the roller with cold glue coating process is one of the most common accessories used by factories and mining enterprises in the production operation for material transportation.
Basic information of rubber coated roller

Drum diameter selection: 25mm, 32mm, 38mm, 42mm, 50mm, 57mm, 60mm, 76mm, 80mm, 89mm, 108mm, 133mm;
Material selection roller : carbon steel galvanizing, carbon steel chrome plating, carbon steel coating, aluminum alloy, stainless steel, ABS, etc.
Selection of drum type : unpowered roller, single chain roller, double chain roller, "O" belt roller, cone roller and groove roller.
Fixing method of roller : spring press in type, internal tooth shaft type, full flat tenon type, through shaft pin hole type.
Rubber coating materials can be natural rubber, nitrile rubber, chloroprene rubber, ethylene propylene diene monomer, polyurethane, etc.
Polyurethane coated roller

Vulcanization bonding method: cold vulcanization bonding method and hot vulcanization bonding method.
Polyurethane roller or rubber covered roller is widely used, the main purpose is cushioning, wear resistance, corrosion resistance, etc., please confirm with our sales department when selecting the type!
According to the different installation methods can be divided into: internal teeth, external threads, milling flat, elastic shaft, cotter pin, etc.
Rubber coated roller As the name implies, there is a layer of rubber on the drum, and different rubber makes different rubber coated rollers. The rubber coated roller can effectively improve the conveying condition of the conveying system, not only protecting the metal drum from damage, but also protecting the conveying materials to reduce friction. What parameters do we need to know to make a rubber coated roller? Next Qingdao Wanhui for you to analyze!
one Diameter of rubber coated roller
Drum diameter selection: 25mm, 32mm, 38mm, 42mm, 50mm, 57mm, 60mm, 76mm, 80mm, 89mm, etc. If the diameter is 60mm, the thinnest one side of the roller should be 5mm. At the same time, our company can also make it according to the requirements of customers.

two Material of rubber coated roller
The material of rubber coated roller is divided into: nitrile rubber, silica gel, polyurethane, rubber and natural rubber.
● nitrile rubber - generally milky yellow
Advantages: oil resistance, good wear resistance, aging resistance, good conductivity.
Disadvantages: poor insulation and cold resistance
Silica gel - a white food grade rubber
Advantages: heat and cold resistance, suitable temperature is generally - 100 - 300 degrees; good insulation performance
Disadvantages: low strength, poor tear resistance, poor wear resistance
Processed roller

TPU is a kind of polymer with good comprehensive properties
Advantages: good wear resistance, high mechanical strength, good adhesion, good elasticity, good reducibility, good flexibility at low temperature, long service life, good oil resistance and aging resistance
Disadvantages: poor integration
Rubber: generally, the color of rubber is white, and white has a fragrance. If it is black, black rubber has more impurities and a pungent smell
Advantages: great flexibility. The price is low. It has good physical and mechanical properties and chemical stability.
Disadvantages: easy aging
● natural rubber - the advantages and disadvantages of natural rubber are not fixed. If different characteristics are applied in different situations, the application situation is not correct, and some advantages will become disadvantages.
Advantages: good elasticity, acid and alkali resistance
Disadvantages: not resistant to oil
White rubber coated roller

three Hardness of rubber coated roller
The hardness of rubber coated drum is generally determined by the conveying materials. The hardness commonly used in the industry is 70 degrees. The hardness below 60 degrees belongs to soft rubber, and above 80 degrees belongs to hard rubber.
The three necessary parameters of rubber coated roller: diameter, material and hardness depend on the size of the conveying material, load-bearing, service environment and so on

There are many factors that affect the quality of rubber coated roller, including the following factors:
1. Rubber quality;
2. The coating technology includes hot vulcanization and cold vulcanization, but the mainstream in the market has been replaced by cold vulcanization;
3. The construction technology and the technical level of the coating workers also have a certain impact on the quality of the coating;
4. Analysis and treatment of different situations by engineers of rubber coating company;
Users must be careful when choosing manufacturers. Distance and practice allow. They can go to the manufacturers to investigate and understand, communicate with their engineers, and make a systematic communication for different problems. In this way, you can better meet your needs and find the right supplier
