High efficiency and energy saving environmental protection granulating technology configuration; High dispersed production process, the mixer with single screw structure, environmental protection and energy saving high efficient polymer dispersion effect is excellent, small host current, energy conservation and environmental protection. Calcium carbonate filler masterbatch mainly PP/PE as raw material, calcium carbonate filler and filling amount to 80% above.
Material after mixer fully plasticizing, scattered into the elevator, after through the cone double feeder material is forced into single screw, the screw core water, all the scattered.
According to the characteristics of the calcium carbonate filler masterbatch, has carried on the significant improvements, the former mixer to the hydraulic pressure type mixer, sealing adopts hydraulic seal, can solve the problem of leaking past mixer powder, greatly improve the effect of the surface modification of calcium carbonate, so as to improve the dispersion effect of calcium carbonate filler masterbatch.
Energy conservation, environmental protection and efficient pelleting machine structure: 1, mixer, 2, 3, taper hoist double feeding machine (dedicated to feed mixer clumps of material) 4, single screw granulator (complete material compaction and extrusion) 5, on blowing the nose (cut into particles) 6, the secondary cyclone separator (for cooling and scatter) is 7, extended air-cooled vibrating screen (filter) 8, finished product bin.
The main production process are three most.
Polyethylene cement formula: calcium carbonate is the main ingredient. But still need to add a few match materials such as (must add suitable amount of lubricant, coupling agent, promoter) auxiliary materials such as granulation can achieve the requirement of production use.
2. Granulation: mainstream of the market at present process as follows: 1. The mixer (made with good ingredients dispersed) - 2. Hoist (will increase mixer refining good material to feeding machine), (3) double cone forced feeding (mixer refining for the dough, with cone double feeder forced feeding into the single screw extruder) -- -- -- -- -- 4. Single screw host (material compression extrusion) -- -- -- -- -- 5. Air-cooled eagerly head (single screw extruder is expected to cut into granular) 6. Cyclone separator (scatter material grain cooling) -- -- -- -- -- 7. Vibrating screen (screen out carefully and big particles) -- -- -- -- -- 8. Bin (finished)
3. The technology key requirements: better raw materials mixed granulation, so that the next stage the paper process won't produce bubbles, fracture, gap, the phenomenon such as hole gap.
