Certification
Our this new type pellet machine both used in biomass wood pellet
and waste pellet making ,waste introduction :
1. Almost in every country in the world, the disposal of trash is a
big problem because of its large amount. According a survey,
Americans produce more than four pounds of trash per person per
day, amounting to 20 percent of the world’s waste. For another, we
must find renewable and environmental friendly fuel to replace the
fossil fuel, as the storage volume in the world is finite. For many
years, opposition to the use of municipal solid waste as an energy
resource has been nearly universal among activists and regulators
because of bad experiences with traditional garbage incineration
which are associated with high level of toxic emissions. While with
the development of technology, solid waste is potential raw
material as renewable energy while reducing greenhouse gas
emissions and the need the for landfill space.
2. Landfills may cause numbers of problems. Damage can include infrastructure
disruption, such as damage to access roads by heavy vehicles.
Pollution of the local environment may occur as well, such as
contamination of groundwater or aquifers by leakage or sinkholes or
soil contamination.
As existing landfillls become filled to capacity and it is more
costly to site new landfills, the development of alternative
disposal methods is becoming essential. In addition, the wastes
being buried contains considerable quantities of energy that can
replace conventiaonal fossile fuels.
Producing energy from trash is known as a “waste-to-energy” option.
Several such options have existed for many years and are in
extensive use throughout Europe. One of the more exciting options
that has been proposed within the last decade is to convert waste
into solid recovered fuels (SRF). SRFs are engineered blends of
nonrecycled combustible waste (general combustible components of
MSW is paper, cardboard, plastics, textiles, rubber, leather, wood)
condensed into fuel pellets or briquettes. Taking advantage of
those fuel pellets or briquettes can be recovered to provide
environmental, economic and resource conservation benefits.
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.
Waste 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 LANDFILLetc .
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 .
