Description:
PVC cable materials Compounding & Pelletizing Line is double stage pelletizing machine. The first stage uses high speed co-rotating parallel twin screw extruder and the second stage is single screw extruder. This combination is because of the characteristics of high speed, strong compounding twin screw and low speed, low temperature, low shear single screw. This line enhances advantage and avoids disadvantage, which is the preferred choice for heat and shear sensitivity of materials compounding modification. It is suitable for granulation of PVC cable material,s hoe sole material, transparent bottle material, PE/EVA carbon black masterbatch and other crosslinked cable materials. This equipment has admirable compounding effect and easy temperature control. It is of excellent safety and simple operation.
Features:
The screw is made of high tool steel 38 CrMoALA or W6Mo5Cr4V2. Special screw combination Euro-style rectangle barrel, reflux refrigeration channel optimized and disposed, which makes temperature difference in D areas smaller.
Innovated design of heater-tightened style insures high efficiency of heat transfer and high longevity of heater.
The material is used high quality nitride steel, corrosion proof or antifriction with corresponding processed special designed two sets of vacuum.
New-style project of parallel three-axis driving makes the convex axis, convey Chain, decelerate and torque get together, which keep it compact, and the key bearings are imported soakage and spraying lubrication integrate smoothly technics, strengthening of tooth face, so they can ensure high torque, high precision and low noise
The selected material of drive components is dainty, including super intention alloy, cementiteing steel, cementiting and grinding.
Working Flow:
Screw feeder → Efficient extruder → Non-stop hydraulic screen filter changer → Cutting → Blower → Storage hopper → Electric control panel
1. Screw feeder: the first step of the pelletizing recycling machine, Pvc plastic flakes/scraps conveyed into the hopper through screw, the screw connect sensor to detect the material in hopper, once the flakes are full in hopper, the screw will stop; and once empty, the screw feeder will begin working.
2. Extruder: to plasticization and degassing, a specialized single screw extruder applied to melt the pre-compacted material. The plastic scraps will well melted, plasticized in the first stage extruder, and the plastic will be extrude by the second stage extruder. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency, especially suitable to heavy printed film and material with some water content.
3. Non-stop hydraulic screen filter changer: double stage filtering, fore filtering in the first extruder, and fine filtering in the second extruder, to reduce the frequency of filtering sieves changing. The requirements on the filter technology depend heavily on the quality of the input material as well as the planned use of granules.
4. Cutting pelletizing: supplied with speed steel and hard alloy steel cutting blades for reliable performance. Compact structure allows less maintenance.
Advantage:
Very low labor request.
Automatic constant temperature control.
CE certification, ISO9001 certification, SGS certification
Stable running, higher output and lower energy consumption.
Configuration based on client requirement and material, and give reasonable suggest.
Application :
This PVC plastic pelletizing machine is design specializes for recycling the recycled washed plastic PVC plastic flakes/scraps, such as PVC pipe flakes/scraps, PVC sheet flakes/scraps etc.
