Company Profile

OPPS GROUP LIMITED is registered in HK for oversea market regarding Biomass wood pellet mill, Rice straws pellet mill, RDF pellet mills, Sludge Pellet mills, Steam Explosion, Membrane Biogas upgrading plants and PSA type biogas upgrading plants, OPM has workshop located in Chongqing gearbox (Now called YuShuo Heavy Equipment).  Here Supported by over 15 workshops (covers a total land area of 530, 000m2) to make the gearbox for wind turbine and grinding mills for cement plants, Monthly capacity for our OPM pellet mills and other equipment is over 100 units. German CNCs has been used widely to make sure the accuracy of our components is top level in the world, so lifespan of our gearbox is over 15 years.

Founded in


During 10 years of continuous investment and development of new generation of pellet press, our pellet press has been acknowledged as the best stable pellet press with highest capacity under same output of electric motor, and the maintaince cost is the lowest in the market. The following is main problems of pellet mill in the market.

1.Every brands in the market has bearing inside roller include German and USA brands. You need to lubricate the bearing every two hours and change the bearing every half a month.
2.For horizontal type ring die pellet press, the main shaft is easily broken and hard to repair
3.For vertical type flat die pellet press, the capacity of pellet press is very low and power consumption.


following is the main advantage of our pellet press:

1. The main shaft is drived by cylindric helical gear.
2. The main bearing is heavy duty branded bearing of high precision quality level.
3. No bearing inside roller, no need of grease lubrication every two hours.
4. Space between roller and die is adjusted and controlled remotely.
5. The carburization for the gear in the heat treatment is up to 2mm, the hardness and wearing resistance is top quality.
6. Germany CNC machine for every components in Pellet Press, the error allowance is very low.
7. The space for Compressed chamber is large, and additional vane to avoid the clog in the chamber.
8. The four lines(instead of five lines) die will avoid the overdue pressure from roller, extend the service time for the roller and die gradually.
9. All the rotated components are lubricated inside the pellet press by the oil pumping externally, and the temperature of oil is lower than 50 ℃ all the time, the span life for the pellet press is extended a lot.
10. The material of roller and die can be selected, for example 40Cr, etc.
11. Compression ratio can be selected based on the different raw material and different moisture For example, the hardwood/soft wood/and moisture is 20%-25%.
12. The power consumption is very low, normally the 1g is 55w, germany machine is 60w-70w. Power saving is 20% more.
13. The inner size of die is bigger than normal machine from china/german/usa, the capacity is higher by 30%.
