Shijiazhuang Gongbei Heavy Machinery Limited
Company Product
name:CRS series Cross roll Screen for coal
screening Working
principle: The screen deck of cross roll screen is composed
of multiple sets of rotary rollers with disks, all disks on
adjacent roller are crossed to form moving screen holes, the
materials in the screening area are classified during moving
process, small particles go downward and large particles move
forward, thus small particles are exposed to rotating disks and are
forced to go through the holes via rubbing of adjacent disks. The
large particles impact and break the agglomerated particles during
movement and clean the small particles on the rollers and disks.
Behind the rollers, there are scrapers to clean the residues and
ensure open holes without plugging, sticking and
pegging. Features: 1. Unique creation **- moving screen hole,
material self-cleaning technology 2. Performance advantages **- high screening
efficiency, high reliability, environmental protection, large
handling capacity 3. Applicable to various material (dry, wet and
sticky material) 4. Screening of particle size:
****0mm 5. Solutions to material sticking and plugging
& pegging problem of traditional roll screen 6. Intelligent PLC control with overload
protection 7. Starter with load, start each roll one by one
from the discharge end. 8. The CRS series cross roll screen was
identified by STATE GRID CORPORATION OF CHINA in July of ***7 that
the comprehensive performance has achieved advanced level in
China Applicable
industries:coal mining, power plant, coal chemical, coking,
metallurgy, construction material, chemical etc. Classification of particle
size:3mm,
6mm, 8mm, *0mm, *3mm, *0mm, *0mm, *0mm,
**0mm Current screening
situation: Material screening is widely used in every
industry. The screening of wet and sticky material (<*0mm) is a
technical problem in China and abroad, and screening of less than
3mm material is a blank space. Low efficiency and high failure rate
have been the technical barriers to traditional screening mode.
Solutions to the above problems with high efficient and reliable
technology & equipment is a major issue to be fixed in the
screening industry. Comprehensive benefits of
Cross screen: 1. No sticking, no
plugging & pegging, smooth operation system 2. Low power, energy saving 3. Few maintenance, less
manpower 4. well sealing, no dust
pollution 5. Remove slack coal before coal preparation to
save power, agent, water, medium, transportation and reduce coal
slime production and reduce maintenance and spare parts cost of
downstream equipments. What can we do for
you? 1. Design and manufacture of screening
equipment 2. Transformation of traditional screening
equipments Advantages: 1. More than *0 years of technical research and
development 2. The best R&D and technical personnel with
the most achievements in crushing and screening
filed. 3. With various equipments of different working
principles for crushing & screening and experiment database for
ten thousands materials . 4. Entrusted National Inspection Center for small
and middle-sized mining equipments as third party inspection unit
to ensure quality.
