Waste Paper Pellet Making Machine , Europe SRF Pellet Mill Machine

The term “garbage-derived fuel” comes from Refuse Derived Fuel, literally translated as: fuel derived from garbage. Solid form (cylindrical strip) fuel made by sorting, crushing, eddy current removal of aluminum, magnetic separation and iron removal, crushing, air separation, compression and drying, referred to as RDF. RDF calorific value is 14595-4782 kJ/kg (3487-4782kcal/kg);

Another type of waste-derived fuel that produces higher calorific value is called RPF. Fully known as Refuse Paper and Plastic Fuel, it is a solid waste-derived fuel made from waste paper and waste plastics sorted from industrial waste and domestic waste. The calorific value range is 20900-41800 kJ/kg. 4993-9986kcal/kg).

RDF&RPF is a concept about non-natural fuels. The idea of ​​RDF was first produced in the UK in the late 19th century, and the United States was the first country in the world to use RDF to generate electricity. The first RDF incineration demonstration plant was built in 1972. Japan began to promote RDF technology in the 1990s. The European Committee for Standardization (CEN) gave RDF a tall name, SRF (Solid Recovered Fuel), which is sold on a global scale.

The application of refuse derived fuel RDF

1. Drying engineering

RDF is burned in a special boiler and used as a heat source in drying and thermal deodorization.

2. Coordinated disposal of cement kiln

When using RDF as a fuel, the burning ash of RDF generally needs to be treated, which undoubtedly requires an increase in operating costs. In order to develop a low operating cost RDF application field, Japan uses RDF's combustion ash as a raw material in cement manufacturing, thereby eliminating the RDF combustion ash treatment process and reducing operating costs.

3. District heating project

In areas where the infrastructure of the heating project is relatively complete, RDF heating can be realized with only a special RDF combustion boiler, and the investment is less. However, in areas where the basis of heating engineering is relatively backward, due to the high cost, RDF heating is not economical.

4. Power generation engineering

In a coal-fired power plant, RDF is co-fired with coal for power generation. The environmental protection project will soon eliminate backward environmental technologies for the benefit of the people.

Vertical Pellet Machine

1. No roller bearing in the chamber

2. Whole machine thin oil lubrication system

3. Special press roller shaft combined with shaft design (planetary mode)

4: Reinforced gear box + world-class gear processing technology

Technical parameter :

Model: SD630 /880(vertical)

Main motor power: 132/160/200KW

Auxiliary machine power: 7.5KW

Capacity: 2-4t/h (according to different material)

Weight: 10-14 tons

Shape parameter (mm): 4200*1500*2200

Roller mode: 2/3 rollers / automatic locking

Cooling method: circulating water cooling or circulating oil cooling

1. Total introduction :

2. No roller bearing in the chamber

3. No lubrication consumption:

The original central oil supply technology ensures that the built-in bearing is lubricated in place and never leaks oil. The professional external circulating water cooling system solves the whole machine temperature control problem, with small volume and high efficiency; the surface temperature of the pressure roller shell is kept at about 90. °C, the ring mold temperature is 90~110°C, and the oil temperature of the chassis is 60°C; the online oil filtration system removes impurities to ensure the lubrication effect;

In addtional ,Because there are no bearings, traditional eccentric shafts, spacers, etc. inside our roller assembly;

Therefore, bearings is avoided using in high-temperature areas and no need to continuously add grease.

Application :

There is no roller bearing in the chamber ,the chamber is larger 2 times compared with traditional ring die pellet mill and vertical pellet machine ,that is to say ,there is only roller shell is in the chamber ,so it widely used in  fiber material such as efb ,cotton ,plasctic etc .

The testing for waste pellets :

We are professional manufacture of this vertical pellet mill used both in traditional biomass such as wood pellet and waste such as paer ,plastic pellet making .
