Product Description

Engineering project: Beijing Energy Investment Holding Co., Ltd. (2×300MW)

- Transformation from twin-roll screen to cross screen

1.1 Working condition:
Coal quality: raw coal + coal slime, ration of raw coal and coal slime 1:1.5-2;coal≤8mm accounts for 65%
Water content: 10%-20% Requirement of particle size: 8mm

1.2 Equipments before and after transformation:
Before: 2 sets of twin-roll screen (ZZS-800), design handling capacity: 800t/h, rated power: 230Kw
After: 2 sets of cross screen (CRS-2220), design handling capacity: 800t/h, rated power: 120Kw

1.3 Work site:

1.3 Before-and-after comparison:

Item	Before	After	Conclusion
Equipments	SZZ-800 twin roll screen	CRS2220 cross screen
Max. handling capacity	550t/h	650-750t/h	Increased 45.5%
Screening efficiency	0-30% (plugging & pegging)	≥91%	Always above 90%
Power consumption of coal feeding system	570536kwh (Apr. 2013)	375315kw (Apr. 2013)	Saved USD178000 of power consumption
Power consumption of coal feeding system	710016kwh (May 2013)	381704kw (May 2013)	Saved USD178000 of power consumption
Fly ash & slag (2# boiler)	Fly ash: 2.27%	Fly ash: 2.06%	Decreased 9.25%
Fly ash & slag (2# boiler)	Slag: 0.42%	Slag: 0.29%	Reduced 31%
Annual maintenance cost	USD30000/set (maintenance, cleaning, spare parts)	Less than USD3000 (spare parts)	Significantly reduced labor and maintenance cost

Addition: (1) Reduced 40% of crushing machine load;
(2) Reduced crushing machine wear on the components (hammers etc.) and saved spare parts expenditure (USD24000).

1.5 Field identification:
In July of 2014, China Electricity Council held a site meeting about technical appraisal of CRS series cross screen in Beijing Energy Investment Holding Co., Ltd. The participants witnessed its magical performance of GONGBEI cross screen,and the committee thought that:

The cross screen features innovate design, simple structure, no sticking, no plugging & pegging, high screening efficiency, large handling capacity, reliable operation, energy saving, environment friendly etc., its comprehensive performance has reached the advanced level in China.

More screening and Less crushing for Energy saving & Emission reduction

Introduction of Cross Roller Screen:
1. Unique creation --- moving screen hole, material self-cleaning technology
2. Performance advantages --- high screening efficiency up to 90%, high reliability, environmental protection, large handling capacity (largest unit handling capacity up to 3000t/h)
3. Applicable to various material (dry, wet and sticky material)
4. Screening of particle size: 3-100mm
5. No sticking, No pegging, No plugging

Applicable industries and materials:
Applicable industries: coal mining, power plant, coal chemical, coking, metallurgy, construction material, chemical etc.

Classification of particle size: 3mm, 6mm, 8mm, 10mm, 13mm, 30mm, 50mm, 80mm, 100mm (Classification of particle size is subject to actual working conditions)

Applicable industries	Materials	Classification of particle size (mm)
Thermal power plant	Raw coal, lignite, coal gangue, middlings, coal slime, petroleum coke, anthracite, oil shale	8, 10, 13, 30
Coal mining and washing plant	Various raw coal, gangue, middlings, coal slime	4, 6, 13, 50, 80, 100
Coking	Coking coal	3
Coal liquefaction, gasification and chemical	Various raw coal, petroleum coke	3, 6, 10, 15, 30
Metallurgy, chemical	Limestone, white mica, phosphate ore, oil shale	3-30, 30-80
Metallurgy, chemical	Aluminium oxide, laterite nickel ore, gypsum, coke, furnace charge	3-80
Construction material	Limestone, dinas, construction waste	3-5, 10-20, 20-40

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. Below the rollers, there are scrapers to clean the residues and ensure open holes without plugging, sticking and pegging.
