Flat yarn spiral dryer screen composed of flat wire, the surface dryer screen is smoothly, depending on the filling yarn added to the spiral dryer screen, air permeability range from 100 to 1380 CFM.
With its flexible and adjustable permeability and perfect surface, the paper breaking caused by airflow disturbance is greatly reduced, thus improving the production efficiency of paper machine, the flat yarn spiral dryer screen mainly used to the high speed paper machine which required high grade of paper.
Description:
High Consistency Cleaner can eliminate heavy impurities larger than 3mm in diameter from recycled paper stock.
As a coarse screening equipment,it is usually a down- stream equipment of hydrapulper. It can also be installed as an important equipment to ensure the operation of down-stream processing equipments.
The special design structure of the forming board is that it can be installed near the breast roller, or the breast roller scraper can be installed. It can move forwards and backwards, and can be adjusted to the best spraying point of the slurry, so that it can achieve a good sheet forming and dewatering effect. . The forming board is composed of a box body and a panel.
Paper Mill Outflow Pressure Screen/Coarse Screen/Fine Pressure Screen
Used for fine screening waste pulp and all kinds of coarse and fine pulp.
1. The rotor is rotated outside of the sieve drum, and the heavy impurities flow away from the sieve drum to avoid clogging the screen cut and prolong greatly the service life of sieve drum.
2. It has low pulse, high screening efficiency and reliable operation.
Features:
This equipment can be fitted with energy-saving rotors: coarse screening.
Rotor, fine screening rotor and headbox screening rotor.
Corresponding shell body and screen cylinder can match each
Different rotor, thereby achieving screening different pulp kinds with
High screening efficiency and low power consumption.
Air Cushion type headbox can increase the sizing pressure to meet the requirements of medium and high speed paper machines. The headbox consists of square taper tube device, evener roll device, top lip plate adjusting device, box body,control system, spraying device, air path system, etc.The headbox is designed with customer performance parameters, which can ensure work performance.
Used in paper and pulp industry for breaking waste paper and wet-strength paper. This equipment is fitted with P.S. Vokes rotor,
which can strengthen hydraulic cycle and fiber defiberizing and also perform continuous breaking with lower energy consumption.
Rotor deviates from the center of trough body and trough body structure is D-shape, which can make the contact between pulp and rotor quicker, with higher frequency.Thereby, on condition of not increasing power and volume, capacity can be increased. Rotor and extraction disc are above the bottom plane of trough body, thus, one low-pressure flow area can form around rotor to gather heavy impurities, thereby the service life of rotor and extraction plate can be extended.
Description
Centrifugal Pumps uesd for The Pulp and Paper mills to deliver the pulp and water. And the Pulp Pumps as the key equipment during the pulp stock preparation.
Single-stage centrifugal pump with full-open impeller design.
Suitable for conveying slurry or clean water with a pulp concentration of 0-6%.
The scope has pump, base frame for placing pump and standard motor, with screw coupling, coupling protection cover, anchor bolts.

With many years of experience in production single layer forming fabric, can supply a wide range of single layer forming fabric. single layer forming fabric can meet many applications, if you need, please get our online timely service about single layer forming fabric. In addition to the product list below, you can also customize your own unique single layer forming fabric according to your specific needs.
Polyester synthetic forming fabric is a commonly used filter mesh in the forming section of paper machine, the forming wire can be divided into 1 layer, 1.5 layer, double layer, 2.5 layer, and triple layer forming fabric, in order to increase the work life of the polyester forming fabric, Huatao weaves the nylon monofilament with better abrasion resistance in the weft, which makes the fabrics life longer and reduces the cost.
The 1.5 layer forming fabric is actually a 5-shed single layer forming fabric that have modified to have extra yarns which provides it the same properties as that of a double layer one. 1.5 layer forming fabric is easy to clean, increase sheet release as well as retention and with the extra fabric provides an excellent drainage.
Paper making felt include: Press felt, BOM felt, MG felt, Pick up felt, Shoe press felt, Combi Press Felt, Seamed felt.
The paper making felt are of good adaptability, smooth surface, low steam consumption, long life and a fine water-filtering performance, which make the paper a superfine surface.
Paper making felt Working Principle:
In the press section of a paper machine, water is removed from the newly formed sheet. The paper sheet is carried by a press fabric between two rolls, where water is removed with the application of pressure. also can be assisted by the use of vacuum and heat.
Dryer screen design and materials are also very important.
For a particular paper machine, the permeability, design and materials of the dryer screen should be adapted to make sure optimum drying from a drying section. The air permeability of the dryer screen has a great impact on the rate of evaporation of water. If the permeability is decreased, then it is reduction in drying capacity of the dryer screen.
The dryer screen, whose air permeability range between 700-1000cfm is used on paper machine for producing higher gsm Kraft and board varieties. On the other hand 100-400cfm dryer screen widely used in medium and high speed paper machine, high numbers of contact areas with the drying surface ensure uniform drying.
Proper chosen of dryer clothing improve paper machine runnability, increased drying rate, improved paper quality and savings energy.
1.The pressure screen basket is composed of a sieve perforated plate, an overflow bucket and a non-perforated plate.
2. There are many small holes distributed on the screen plate, and the vapor passes through the small holes from bottom to top, transfers heat and mass through the liquid layer on the tray, and then rises.
3. The liquid flows through the tray according to a certain route, and the liquid is held by the vapor with a stable flow rate, and flows through the overflow hopper to the non-porous plate (liquid receiving tray) of the next tray.
4. The thickness of the liquid layer is determined by the height of the inlet baffle and outlet baffle on the tray.
