Description

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.
