Oil Resistant Conveyor Belt used in recycling plants
Heavy-oil conveyor belt treated coal in cooking plants and electric power generating plants
Oil resistant belt carry parts and components coated with machine oil; heavy-oil treated coal in cooking plants and electric power generating plants; soybean draff, fish, meat and other oily materials. materials containing non-polar organic solvents and fuel. The carcass is formed from polyamide or polyester plies.
OIL AND FAT RESISTANT CONVEYOR BELTS
life and performance of a conveyor belt largely depends on the material. To be conveyed on that materials having Oil and fat can have a very detrimental effect on the performance and life expectancy of a conveyor belt. Because it penetrates into the rubber, oil is easily absorbed by the rubber causing it to swell and distort. The rate of absorption increases with the temperature often resulting in serious operational problems.
Oil and fat resistance can be divided into two sources – mineral oils and vegetable & animal oils and fats. Mineral oils are the most aggressive and demand a particularly high level of protection.
Oil resistant conveyor belt covering with nylon canvas or EP canvas
Oil resistant conveyor belt covering adhesive USES butyronitrile with high acrylonitrile content as the main material, USES cotton canvas, nylon canvas or EP canvas as the strong layer.Suitable for conveying oily materials and contacting various working oils (except fuel oil or solvent oil).
It has the advantages of low volume change rate, high strength keeping rate and wide application range.
Physical and mechanical properties of oil-resistant conveyor belt cover adhesive :
type | tensile strength/Mpa | elongation/% | abrasion/mm3 |
LO | ≥14.0 | ≥350 | ≤200 |
DO | ≥16.0 | ≥350 | ≤160 |
Note: LO- oil resistant conveyor belt under general conditions;DO- conveyer belt with strong resistance to wear and oil under operating conditions. |

specially designed Oil Resistant Belts
Monster rubbers specially designed Oil Resistant Belts are not effected by paraffin oil, naphthene-based oils, petrol animal or vegetable fats etc. suitable for transporting goods which contain any type of oil.
Oil and fat resistant covers belt using:
Monster conveyor belts using oil and fat resistant covers can be found in many different industries like chemical & fertilizer industry, wood, paper & pulp, sugar & food, transshipment and recycling plants. Covers that are resistant to both oil and fire are also available, Specialist HTN (Heat & Oils Resistant) Belts, can be provided for Hot Mix Bitumen plants and solvent extraction plants.
These are suitable for:
Concrete plants | Recycling and mineral processing plants |
Waste sorting & Compost machines | Metal processing industry |
Scrap recycling | Timber industry |
Sawmills | Excreta & sewage sludge conveying |
Corn, rape and soilages conveying | Solvent extraction plants |
Paper industry |
