Bulky Waste Shredding Disposal

Types of Bulky Waste
Bulky waste might be too large to be handled by nature, but it is far too valuable to be left unutilized. Objects that are awkwardly sized and heavy – for example furniture, mattress, large devices and appliances, are traditionally classified as bulky waste. These Large objects cause headaches in transportation, and moving them around is often expensive.
Method of Processing Bulky Waste
Pre-shredding bulky waste enables loading the material compactly, which cuts transportation costs. With a smaller gain size, the waste is more efficient to process: screening and sorting can be done more accurately, and different materials are faster in their own stacks and continue to the recycling processes.
Harden created the first bulky waste shredder in China in 2010 and kept researching, innovating the shredding technologies for years. Harden provides completed primary shredding system including feeding, separating, shredding and stocking bin. Feeder can be a grabber, chain conveyor or lifting machine. Harden solved some major problems of bulky waste shredding such as materials hanging shaft and dust leakage. Covers well designed and pulse deducting unit makes no dust workshop.

System A is suitable
for achieving rapid volume reduction treatment of mixed bulky waste. Its compact
layout and full sealing structure with vacuum dust collector, which can achieve
better dust removal effect and realize dust-free working environment. System A
adopts motor-driven double-shaft shredder as core equipment, features large
processing capacity, stable performance, and convenient maintenance, easily
crush any type of large garbage quickly.
Its sealing structure
also ensures long-term stable operation of equipment even under harsh
environments.
System
B adopts large-scale primary shredder as core equipment, features large
shredding space and strong shredding capacity, and is suitable for shredding
various types of bulky wastes at the same time. Multiple operation modes can be
set according to different material properties, reaching the best shredding
result, accurate metal sorted and finally good result in volume
reduction;
The
whole line is sealed with two sets of vacuum dust collector, which can achieve better dust removal
effect and realize dust-free working environment.
System
C is suitable for the classification and recycling of large quantities of waste
mattresses and sofas. Through the two-stage crushing process of a double-shaft shredder
and a four-shaft shredder, the crushed materials sorted by air separation and magnetic
separation, realizes ferrous metal and combustible materials separate from the
bulky waste and formed RDF particles by granulator, which maximizes the
recycling of resources;
The
complete system is automatic and efficient, with high recycling value, achieves
the development from simple waste disposal to waste resource recycling economy.
Double Shaft Shredder
Our
double shaft shredder equips intelligent double-shaft motor, with the
characteristics of low speed and high torque, which can adapt to crushing
various types of wastes and ensure long-term stable operation;
The
cutters are made of imported cold work die steel, which are powerful, tough,
wear-resistant and impact resistant. The detachable structure
enables quick maintenance and fully use of blades, with low maintenance costs
and short replacement cycles.
Double Shaft Hydraulic Primary Shredder
The
intelligent double-shaft hydraulic primary shredder enjoys a large crushing
space, which allow multiple pieces and types of bulky waste crushing at the
same time; the unique control program allow to set different operation mode for
different types of bulky waste to achieve the best crushing performance; the
core components are imported from famous brands with stable performance; the
cutters, the inner wall of the crushing box and the spindle are wear-resistant
coated, with longer repair cycle and lower maintenance cost.
Four Shaft Shredder
The
four shaft shredder adopts a combine of double main shafts and double vice
shafts, which improves the crushing efficiency. Each shaft is driven by an
independent motor, with overload protection. The bottom is installed with a
screen, which can be customized according to customers. The discharge particles
are fine and uniform, which provides good conditions for the subsequent sorting
process; the screen is easy to disassemble and maintain.
Conveyor
The feed conveyor adopts hinged galvanized chain plate for transmission, with
the features of strong impact resistance, large bearing capacity and strong
wear resistance.
The
discharge conveyor adopts a snap-type sealing cover structure, which enjoys
good sealing effect, easy maintenance and simple clean.
The de-rusted
surface can meet the requirements of anti-corrosion and ensures equipment runs well
under severe environment.
Intelligent
control functions include remote start and stop, emergency stop, speed control,
and overload reminding.
Magnetic Separator
We
adopt permanent magnet self-unloading type of magnetic separator, which can
efficiently remove iron metal. Not only recycling the metal but also avoids metal interference
on equipments in
the coming disposal processes. Avoid dust spilling, a sealing plate is added
to the periphery of the magnetic separator to form a closed space, of which a
dust removal interface is set on the top, and the dust is filtered through a
dust collector before being discharged.
Dust Collector
Due to
the possibility of dust pollution during crushing and transportation, bag-type dust collector can be selected to collect the dust generated in the system through the
pipeline, which effectively improves the working environment and protects the
staff and equipment.
Air Separator
The
materials are sorted by air power based on the gravity characteristics of the
crushed materials. The heavy materials fall directly to the bottom of the
separator, and the light materials are blown to the back-end conveyor through
the air flow instead of manual sorting.
Granulator
The
granulator is a device that forming RDF particles of light materials at the
end. The material can be extruded into RDF particles base on the principle of
high-speed stamping. The particles features high density and compact; the size
of the RDF particles is determined by the die of the holes. The size can be
customized according to the user's requirements; the punch of granulator is
made of cemented carbide steel, which is heat treated to increase the surface
hardness and wear resistance, thereby prolonging its service life.
