Screening machine(Patented product), it is our company according to
the market investigation, development of latest patented products.
Suitable for dressing , power plant, metallurgy, medicine, chemical
industries etc. It completely solved the current domestic and
foreign common sticking and blocking problem of vibrating screen,
changing the dust pollution is serious, high noise and vibration
large poor working environment.
Screening machine uses two AC motors, they drive teeth roll rotate
synchronously , screening, meet the size requirements, then
directly into the boiler and burning , do not meet the size
requirements, need to be crushed again.
Ⅰ.Screening structure without sieve plate,high efficiency
·The unique roller sieve structure ,the material in the particles
meet the size requirements of the mandatory discharge. Close to the
size requirements of the embedded material can be broken in two
teeth rollers to improve the screening efficiency. The rear of the
device to reduce the work load.
·Materials in the composition of the teeth rollers screen surface
for wave-flip motion, fast stratified layers of material can be
through a sieve. Screening efficiency than other forms of screening
Ⅱ.Themoisture content of material without any
·Two adjacent sieve rotation axis intersection in the opposite
direction, there is a mutual scraping effect on high-moisture, clay
content of the material for screening will not appear sticky and
·Sieve seam for space multiline special form, can effectively solve
the sheets and strip material difficult to control the actual
problem. Ensure more reliable particle size requirements.
Ⅲ.Strong distribution of material effect
·Teeth roller screen also has a strong distribution of material
effect, can in all the width uniformity to follow-up equipments
feeding. Prevent follow-up equipments appear to swerve wear
phenomenon. Improve the service life of wear parts.
Ⅳ.Use wear-resistant materials,the service life is long
·Teeth roller is wear-resistant materials and surface hardening
processing. Lower rotating speed, the service life of teeth roll is
up to 1 ~ 2 years .
·Advance broken,good way to prevent a super-large material occurred
at the impact rear equipment.Have broken the same time so that the
material inside the crack.making it easier to follow broken.
Ⅴ.Smooth operation,low nois,small vibration
·Machine totally-sealing operation, low noise, small vibration,
take up the space is small. Suitable for high floor installation
using and whereabouts coal drop pipe rigid connection. Especially
suitable for no screening equipment system coal system field
·patented product-New type of screening-crusher is system coal
system design selection and technological transformation preferred
equipment.Unique screening devices to reduce material excessive
crushing,carbon-in-ash and improve the economic benefits of boiler
combustion is very remarkable,specific details see to screening
machine economic benefit column.
Analysis on Benefit of sieving device
The discharging granularity of DCBLQ screening machine can reach
Discharging granularity between 0~8mm
Screening machine can discharge the materials which meets
requirements before into crusher,can avoid to crush repeatedly,
effectively reduce the dust, improve the boiler efficiency, while
for reducing crushers operation load also play a major role.
With 300 thousands KW units 1025t/h CFB boiler for example:
A screening machine normal work every work line can advance sieve
about 30% of coal, it is not necessary to enter the crusher and can
directly send into boiler burning, this is equivalent to alleviate
crusher crush 30% coal-fired need work load, the crusher of this
boiler, gross power is about 1000KW , and screening machine
supporting power is about 45KW, So, after supporting screening
machine, can reduce work load about 255KW/h, running 7000 hours a
year, the cost of a KW/h is 0.6 yuan, so save the cost of
electricity is about 1100000 yuan. While supporting the screening
machine greatly reduce dust content of cinder, for the whole of the
boiler efficiency can be increased about 1.5%, save coal is about
30000 ton a year, direct economic benefits about 10 millions yuan a
Thus, screening machine for reducing the dust content of cinder,
improving boiler operation efficiency, played an important role,
according to the different coal and different effect.
