Dryer Screen For Paper Machine

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.

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. Paper making felt Classification A press felt for the press or dewatering section of a paper machine is formed with an inner woven fabric and with a plurality of longitudinally extending, transversely spaced heavy yarns or strands which are supported on the bottom surface of the fabric by a relatively light cross-machine yarn or binder pick which interconnects the heavy strands with the warp yarns of the fabric. It is a kind of precious material in paper making industry. It can be divided into three types: wet felt, upper felt and dry felt according to the uses. There are Two series of paper making press felt available in the market, Endless Press Felt and Seamed Press Felt And Endless Press Felt could be divided in to some types according to the structure, Single Layer Felt, Double Layer, and Laminated Layer. Paper making felt Feature 1. High anti-compaction capacity. 2. Extremely high elasticity and recoverability. 3. Strong drainability abd larger void volumn. 4. Long holding time of wear resistance and plastic strength of felt. 5. Smooth felt surface and even pressure distribution.

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. The ideal 1.5 layer forming fabric for most paperboard and packaging grades applications, especially where a smooth top surface and long life potential are desired. In addition, Clean mesh yarn technology provides maximum resistance to premature fabric contamination. Polyester 2.5 layer forming fabric are also known as support shute double layer forming fabric or double layer extra designs. It's a standard double layer design with an extra shute yarn added on the forming side between the 2 regular cross direction yarns. This yarn increase the pulp fibre support and meanwhile create a more open structure as the amount of wear side yarns is reduced, compared with the forming side. 2.5 layer forming fabric's weaving effect greatly increases the fiber support index due to the addition of a fine weave at the top. The ratio of the top and bottom wefts is 2:1. It suitable for paperboard,newsprint,writing paper,tissue paper,printing paper,kraft paper. The SSB 3 layer forming fabric or "wire" of a paper machine is the continuous belt or belts of mesh screen upon which the paper sheet is formed. Most modern SSB 3 layer forming fabric are comprised of polyester monofilament. The weave pattern and layering of a SSB 3 layer forming fabric is designed to meet stringent requirements of dimensional stability, resistance to abrasion (on the wire side), minimum resistance to drainage, minimum wire-mark, and (sometimes) maximization of retention of fiber fines.

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.

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.

High Consistency Cleaner 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. Low Consistency Cleaner Application: HT series low consistency cleaner is suitable for cleaning fiber suspen- sion with the consistency of 0.4-1.2%. It can efficiently remove light impurities, hot melt impurities, heavy impurities, pulp rejects etc. In addition, it can also remove foam plastics, chips fragments., ink particles and air efficiently which results in purifying stock in the approach system prior to paper machine. It can make coarse screen in the recycled paper fiber efficiently simplify the processing procedures and reduce power consumption. Design Features: It consists of tangent inlet, accept outlet, cylindrical up-part with a plug-in deaeration tube, middle part of cone-type separate tube, nozzle or lower part of reject discharge controller, etc. It is a hydrocyclone cleaner. Under the pressure stock enters the cleaner tangentially and generates high-speed vortex in the cone-tye separate tube, by which.the vortex whose direction of axes near the wall of the separate tube will be directed to the ends of the cone, and the heavier impurities are fung against the wall of the cleaner and discharged at nozzle or by reject controller.The accepts gather in the center of the separate tube to form a main stock flowing from compared with ordinary L. C. cleaner. It features with a longer separate cone and incorporates a centered deaeration tube which results in higher effIciency in removing impurities as well as being able to remove light impurities hot melt ma- terial and air. When using HTseries low consistency cleaner.almost no jam will happen in the operation, it ensures high effIciency in cleaning stock as well as accepts with high and constant quality.
