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.

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.

Huatao has developed a wide range of spiral dryer screen to meet each client's needs helping to reduce operation cost through energy efficient solutions. Also called as Spiral link dryer fabric or SLDF, spiral dryer screen is assembled with spiral loops linked by a pin yarn inserted in the adjacent holes. Spiral fabrics are widely used in various industries as paper machine dryer screen, drying & conveyor belts, filter cloth or screening media. Excellent materials are adopted to make the spiral fabric to protect against hydrolysis and high temperatures conditions. Depending on the filler wire added to the spiral dryer screen, air permeability range from 100 to 1380 CFM.
The selection of dryer screen is depending on the various paper machine parameters such as paper grades, dryer cylinders configuration, dryer cylinder temperatures, air balance in the hood etc. Dryer screen design and materials are also very important.
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.
