Detrashing Equipment

Product Description

FRD also supplies a wide range of detrashing equipment, including low density cleaners and reject sorters. The detrashing machines are used to remove contaminants from the pulp in the first stage of stock preparation processes.

1. High Efficiency High Density Cleaner

1% Consistency: 8-140 t/d. 4% Consistency: 15-276 t/d.

The FRDC series high density cleaner is mainly used for cleaning and purifying different kind of paper pulp. It is internally designed with a flow guiding device that allows the paper pulp to rotate after entering into the machine. This pulp cleaner has a 50% higher efficiency than a traditional cleaner.

The high efficiency high consistency cleaner can easily remove large, heavy, or light impurities, such as gooey mixtures, sand, paraffin, hot melt adhesives, plastic sheets, dust, foam, gas, iron scraps, ink particles and more from the paper pulp using a centrifugal principle.

Technical Parameters of the High Density Cleaner

Model	Capacity (T/D) 1% consistency	Capacity (T/D) 4% consistency
FRDC1	8-15	15-30
FRDC2	17-26	29-55
FRDC3	25-46	43-92
FRDC4	36-46	57-115
FRDC5	57-98	115-200

2. Low Density Cleaner, KDC Series

Capacity: 4~20t/d
FRD's KDC series low density cleaner is a high quality and performance pulp detrasher. It is characterized by a small floor space, easy operation, high purification efficiency, wear and pressure resistance, and a long service life. For customers that need a detrashing system for purifying pulp with a low consistency, this series of pulp cleaners is an excellent choice.

Working Principle
According to specific gravity differences between fibers and impurities, the impurities can be separated from the pulp at the bottom of the cleaner under centrifugal force. The impurities and purified pulp will then be discharged separately from different ports.

Technical Parameters of the Low Density Cleaner

Model	KDC-606	KDC-270	KDC-350	KDC-610	KDC-650	KDC-800
Pulp consistency %	0.3-0.7	0.6-0.8	0.6-0.8	0.6-0.8	0.6-0.8	0.6-0.8
Inlet pressure kg/cm2	3	2.5-3	2-2.5	2-2.5	3	3
Capacity (t/d)	4~5	5~6	6~8	8~10	12~15	18~20

3. Reject Sorter

Our XZS series reject sorter is also referred to as a rejects separator, or a reject screen, and is mainly used in wastepaper recycling systems to sort and screen tail pulp with a high content of contaminants. When compared with other tail pulp screens, this reject sorter features an easier operation. In addition, the pulp detrashing machine comes with a high fiber recycling rate of 70% and a closed structure.

Technical Parameters
Size: 280-380mm
Inlet consistency: 1.0-3.5%
Detrashing consistency: 15-20%
Capacity: 10-35t/d
Motor power: 37-55kw

4. Low Density Cleaner, 606 Series

Capacity: 230~270L/min
FRD's 606 series low density cleaner is great for pulping and detrashing systems. This particular detrashing equipment is primarily used to remove light impurities from different types of paper pulp under high stock consistency, especially light impurities found in secondary fibers, such as plastic sheets, hot melt materials, wax, goo, ink particles and more. In addition, this low density pulp cleaner can remove free or slightly combined air in the paper pulp.

Our single low density cleaner boasts a large production capacity and is a leader on the Chinese market. This allows the number of cleaners in the pulping system to be reduced, and the stock cleaner offers a stable operation, high reliability, and cost efficiency.

Working Principle
The pulp cleaner comes with a high efficiency, due to its unique design. During the downward spiral movement of the pulp, fibers will be thrown to the inner wall under centrifugal force and drained from the purified pulp outlet, while the light impurities will gather in the central area of the cone, and then discharged through a pipe from the bottom.

Technical Parameters of the Low Density Cleaner

Capacity	230~270L/min
Inlet pressure	0.20~0.30mpa
Single stage volume slag rate	10~14%
Inlet consistency	0.4~1.0%
Outlet pressure	0.08~0.15Mpa
Single stage solid slag rate	5~8%
