X(S)N-3 Pressure dispersion mixer for rubber and plastics

  • Light-weight high-efficiency and energy saving type modern device for processing rubber mixing and plastic mixing

  • A complete range and satisfactory variety of series products and the annual output and sales volume rank first in the nationwide same trades and professions.
Features

  1. Under the hermetically closed, pressure and temperature controllable conditions, the rubber/plastics and other accessory ingredients can be successfully kneaded or plasticated with the characteristics of high production efficiency, homodispersion of materials, good quality, no contamination to environment, convenience for the processes of material change, color change and cleaning.

  2. The mixing chamber, rotor and float weight and other parts are all adopting jacketed structure for the availability of ingoing of media, steam, conducting oil and water for heating and cooling so as to suit the various requirements for the process of rubber mixing or plastics plasticating and to ensure the processed quality of materials good and stable.

  3. The spiral angle and the working length of the wing of the rotors are designed intelligently and reasonably and they can make the materials obtaining an optimal kneading effect. The wings ridges and the end surfaces of the rotor are bead welded with the abrasion resistant sintered carbide and the faying surfaces of mixing chamber, rotor and pressing weight directly touching with the materials are all polished, ground and plated with hard chromium and consequently the surfaces are smooth and bright as well as corrosion resistant.

  4. The materials can be charged from the rear door (or the side) of the machine frame and turn forward the mixing chamber in 140¡ã for discharging the materials and in doing so, it will be either convenient for the linkage of the first and second working procedure of the production flow or for the convenience of the observation and cleaning of the mixing chamber and rotor.

  5. At the joint between the top of mixing chamber and the cantilevered arm of the frame adopt arc-shaped plate-groove labyrinth type sealing and therefore the sealing dust prevention effect is very good. The end face of rotor is sealed by end contact sealing with external pressure type non-lubricating sealing and it is abrasion resistant and durable.

  6. The turning mechanism adopts the enveloping worm pair (TOP) and it produces a high driving coefficient of performance and high bearing strength and, in addition the discharging of materials with no shutdown can be carried out successfully so that it avoids the frequent starting up of the motor and consequently it prolongs the service life of it to a large extent.

  7. The electric-control system adopts PLC device and it possesses of a perfect and reliable automatically-controlled monitoring and alarming functions as well as the necessary interlocking protective function.

Vertical Shearer  
This Vertical Shearer is mainly used for cutting off the different width and angles of rubberized hanging cloth and canvas cloth. This shearer is performing to complete the cutting motion by automatic control through the coordination of mechanism, electrics and pneumatics. This shearer can be turnable within the range of 0-45¡ãand cutting the hanging & canvas cloth from different angles. By adjusting the length of main driving crank different width and breadth of hanging & canvas cloth can be obtained.

Series of rubber extruder
The extruder and its accessories are one of the most applied in rubber and plastics line, which mainly used for extrusion of tire tread, inner tube, rubber pipe and tube, rubber strip and belt, it is also used for sheathing electric wire, electric cable, and metal pipe, as well as for feeding to calender. Recent years, owing to the pin-barrel cold feed extruder developed and applied, it has good features such as high efficiency, energy-saving, better plasticity, lower temperature of outgoing rubber etc. So the extruder has been applied in more and more wide field. Now it is becoming a new generation of high efficient rubber processing equipment.

Pin-barrel cold feed rubber extruder series
Features

  1. The barrel is composed of several zones. In the feed zone of barrel with the spiral slots. In the plasticity and extrusion zone different number of pins are fitted which enhance mixing and plastic capacity for extrusion material.

  2. The screws and barrels made of high quality alloy steel with nitrogen hardening makes it more wear-resistant and more corrosion protection.

  3. According to requirement of process the temperature in each zone may be automatically probing and control for each zone with good sensitivity.

  4. The extruder is driven by a change frequency motor or D.C motor, which achieve continuous and smooth speed regulation.

  5. Owing to the screw with higher efficiency and pin-barrel are fitted. The extruders include better mixing and plasticity result, higher extrusion, capacity, and lower temperature of the outgoing rubber. So that the output of production and the quality of product are raise.
