single fiber separator

Functions of Single Fiber Separator

1. Three fundamental functions: secondary defibering, separating light impurities, removing heavy and coarse impurities.

2. With the defibrator in pulping process, it’s possible to use the poor waste paper and reduce the pretreatment of the raw material.

3. As a reject screen, fiber separator can also handle with coarse impurities.

Advantages of Tail Pulp Treatment Equipment Single Fiber Separator

Defibrator is a modern equipment to break, separate and screen fiber in paper pulping process. With fiber separator, the production capacity of hydrapulper will be improved. The fiber separator machine can also reduce the pretreatment of raw materials, save 10-20% unit energy consumption, obtain high quality slurry, low fiber loss.

single effect fiber separator

ZDFD Series Single Effect Fiber Separator machine equals to a combination of one sealed horizontal waterpower pulp thick liquid machine and one light & heavy impurity of removing the dregs device with compact structure and high effeciency.

Application & Features of Single-effect Pulp Separator

1. Mainly used for secondary breaking and screening of waste paper pulp, meanwhile, separating the light and heavy impurities from the pulp.

Screen plate single effect fiber separator also can be used as tail pulp treatment equipment.

2. Specially designed impeller can break fiber effectively and it is good for separating and removing light and heavy impurities.

3. Automatically discharge according to requirement, run reliably.

m.c. pressure screen

ZNS Series M.C. Pressure Screen, pressure screen for pulp and paper machine is mainly used for coarse and fine screening of various waste paper pulp.

Application of M.C. Pressure Screen

Mid Consistency Pressure Screen is a kind of advanced pulp screening equipment in modern world. This pressure screen machine is a new generation of pulp screening equipment developed by Zhengzhou Leizhan, absorbing the international advanced technology. Compared with the general Low Concentration Pressure Screen, the Mid Consistency Pressure Screen has the advantages of strong adaptability, energy saving, water saving and high production efficiency.

Structure Features of ZNS Series M.C. Pressure Screen

1. Double Mechanical Seal from American brand safeguards the bearing from Japan. Seal water flow automatic detection alarm device makes sure the system runs safety. Interlock system enables the service life of equipment.

2. European standard pulleys. Automatic oil injection made from Korea and pressure water alarm device from from Finland, sensor from Germany. Convenient disassembly and assembly, less lose of fiber. It can reduces the amount of water cycle and system energy consumption.

3. Various rotor pieces, efficient and energy-saving.

4. Weir plate structure, overflow pulp feed, reduce heavy impurities wear sieve drum.

5. Heavy impurities discharge pipe ensures the screen basket runs safely.

6. Manual argon arc welding, perfect welding seam.

light impurity separator

FQJ Light Impurity Separator, the apple screen is used to separate light impurities and tailing in coarse screening section.

Application & Features of Apple Screen

1. The main body of Light Impurity Separator is an inverse conical design, concave top structure, can form a a strong vortex, forming a alow pressure area in the top center and getting the light impurities and discharge them outside effectively.

2. Pulp outflow chamber of rotor is higher than undersurface of shell, forming a low pressure area around the rotor to collect heavy impurities. Under centrifugal force, the heavy impurities are thrown to the outermost of eddy and deposit in the groove that is outside the sieve plate for discharging. At the same time, it will reduce the wear to cutter and sieve plate, prolong the service life of them.

drum screen

ZST Series Drum Screen, rotary drum screen equipment for waste paper is applied to remove light impurity in the process of waste paper pulping.

Application & Features of Drum Screen

1. Optimized helical blade and water spray system ensure the high purity of impurities and less loss of fiber.

2. Simple structure, reliable operation and easy maintenance.

3. Effective screening, low motor power.

ZSF Series Hydrapurger is applied to remove impurities and little weighty impurities in pulverizing machine in the pulp-making process.

Application & Feature of Screening Equipment Hydrapurger

1. Compact structure, high efficiency and can be greatly simplified the process of waste paper, and let the equipment continuous operation, reducing power consumption at the same time.

2. Slurry get into the tank from the pulp inlet, and rotating with high-speed by the work of impeller so that the impeller broken the slurry secondary.

3. The slurry after broken get into the next process by the sieve behind the impeller, while go through the pulp outlet and pulp pump.

4. Part of the slurry containing light impurities get into the cylinder screener through light impurities outlet pipe ,and into the process of separate slurry and the light impurities.

5. The heavy impurities outlet pipe in the bottom of tank will eliminate weight impurities regular.

6. This series of equipment and pulper including cylinder screen can be controlled by PLC in the production process, to enable them to continuous automatic operation.

NLS Inflow Pressure Screen is mainly used for fine screening before paper machine. The inflow screening equipment also has a slot screen basket. Automatic oil injection device, seal water detection alarm device of the pressure screen ensure the safe running of equipment and reduce maintenance.

Work Principle of Inflow Pressure Screen

Stainless steel screen drum is wear-resisting, large throughput, high screening efficiency.

When the inner pressure screening equipment is running, the pulp with pressure which has’t screened, goes into the outer of screen drum. By means of pressure difference inside and outside, the qualified pulp under pressure through the slot hole into the sieve drum, and derives from the pulp at the bottom of the accepted pulp outlet. Impurities that can’t go through the slot hole fall to the bottom, and discharge out from the discharging pipe.

ZSK Series Vibrating Screen, the impurity removal machine in pulp tailing processing is used for screening and removing various impurities in pulp suspension.

Application & Features of Impurity Removal Equipment Vibrating Screen

1. Device equipped with feeding diluted steady slurry box; Inlet pulp concentration flow is stable.

2. Sieve plate bottom has gas sealing design, with self-cleaning function.

3. Eccentric rotor under excitation device, safe and durable.

4. Screen area equipped with water spray device, which is benefical to fiber recycling.

5. Low power consumption, simple operation, easy maintenance.

impurity reject separator

PZ Series Reject Separator combines the function of paper defibering and impurities separating.

Application & Features of Reject Separator

1. PZ series deslagging machine is an ideal equipment used for waste paper pulp in the processing of the tail pulp system.

2. The slag discharge separator uses close type operation, avoiding the pulp liquid splashing, the effect of treatment is fine, reducing the lose of fiber, the expenses of deslagging are low. Above all, this series equipment is specialized in dealing with the tail pulp.

3. It can remove light impurities and disintegrate little pill in fiber, and keep the slitting plate unimpeded, so that the customer do not need to stop working for cleaning the screen frequently.

4. Fiber recovery is about 70%, slurry concentration is 1%-2%, deslagging concentration is 15%-20%, and it is more easy to operate and maintain compared to other tail pulp treatment equipment.
