The drum pulper system consists of a rotating steel drum aseembly. One end of the drum is a high-consistency zone where chemical impregnation and defiberizing are done. Reject material is separated from the fibers in the adjoining screening zone, and then discharged from the other of the drum when the recycled furnish is wetted and then repeatedlly dropped on hard surface. Gentle but effective shearing forces are created which fiberize the paper without disintegrating the contaminants.
2. Performance
A rubbing effect is added when a rolling motion is applied between the impacts. Ink, size, laminates, and hot melt substances are effectively loosened from the fiber. The stock collected in the bottom vat has been screened and only very small particals. Such as sand, can pass with the accept fibers. These contaminants can easily be removed later in the process.
Two drums pressure screen is the heart of the approach flow system for the modern paper machine. The special designed corrugated screen plate can provide ideal turbulent flow near the screen cut. It can keep constant distance between rotor and screen cylinder all the time and has the structure of strong purification of rotor to screen frame, so it can avoid the apprearance of the stock stopping up or blocking up and flocculating.
Structure
The special designed accepts pipe structure which located under the screen cylinder and rotor is able to deliver the accepts flow after screening to the accepts outlet from all sides of the screen, so the accepts deliver is stable and without pulse. It can disperse the fiber filler and papermaking aid and fluidize. It can also screen out remained impurity in the stock and impurity from the broke system, so it has the function of guaranteening the quality of the stock. At the same time it can meet the need of all operation of the paper machine headbox.

1. Pricinple and Performance
The fiber classification screen provides practical, economical and proven method to separate long and short fibers continuously. Long and short fiber can be separated to appropriate multiple grades. In a single grade application, short fractions can by-pass refiners needed only for long fiber treatment, and the two streams are recombined of improved stock.
2. Strong Points
Especially suitable for the treatment of OCC pulp.
High Efficiency, Low Power Consumption.
Easy to operate and stable performance

1. Main Function
Gravity Cylinder is designed for thickening of fibrous in pulp and paper industry, i.e. chemical pulp, ground wood, waste paper, rag pulp etc.
2. Working Principle and performance
Gravity Cylinder Thickener, provided with a pick-up roll, is used particularly for continuous thickening under stable input conditions. The machine capacity depends on the sort and mainly on the dewatering speed or refining rate of fibrous stock and its input consistency. This machine provides capacities ranging from 10 to 122 t/d. A dewatering drum, covered with a coagulating screen, is permanetly rinsed with washing water from shower tubs with flat-shaped jets. The input consistency is approx 0.5-1.0%, the output consistency is approx 4-6%.

Disc Thickener is maninly used for the low consistency stock thickening. The water log installation height is not needed. It can replace traditional gravity cylinder thickener. In the same floor space, the throughout of the gravity disc thickener is serval times more than that of the gravity cylinder thickener, so a lot of space and power can be saved.
2. Performance and Working Principle
The pulp at consistency of 0.8-1.2% enters the vat and attached the disc sector, filtrate is guided by hollow shaft and discharged out at two end. Stock attached on sector is knocked off by high-pressure shower. The thickened stock at consistency of 3-4% flow over the plate of adjusting valve and into discharge chamber where it is out feed. The rotation speed of main shaft can be adjusted for required outlet consistency and capacity.
3. Strong Point
Thickening of broke or washing of low consistency pulp systems;
Compact design;
Variable speed drive, very low power consumption
PC-950 paper cup machine is improved based on the normal chain driving type. This machine is based on Open Cam System(No Gear Box).This machine runs a whole procedure of paper-feeding, cup-fan-wall sealing, oiling, bottom punching, heating, rolling, rimming, rounding and tripping.
It is an ideal equipment for producing drinking cups, market cups, coffee cups, advertising cups , etc. It is widely used for hot drink and beverage. If you need double pe coated paper cups or paper gram higher 250g/m2, we recommend you to use Ultrasonic paper cup machine. It can produce single pe coated paper cups and double pe coated paper cups.
