Product General Information:

Commercial Terms of Products:

Description:

The PVC high-speed mixer is the core pre-treatment equipment for PVC plastic processing (pipes, profiles, sheets, cable materials, etc.), used to quickly mix PVC resin, stabilizers, plasticizers, fillers, colorants, and other powdered/granular/liquid materials evenly, and complete the integrated equipment of heating, drying, coloring, adsorption, and pre plasticization.
1、 Basic structure (mainly vertical)
Mixing pot body (container)
Material: 304 stainless steel welded/stamped, mirror polished inner wall, wear-resistant, corrosion-resistant, non stick material.
Outer layer: heating jacket (thermal oil/resistance heating)+insulation layer; Hot mixer with heating, cold mixer with cooling jacket.
Mixing blade (core)
Form: 3-blade/multi blade turbine, folded line propeller, high shear propeller (stainless steel precision casting/wear-resistant steel).
Speed: Dual speed/variable frequency (commonly 430/860 rpm, blade tip linear velocity can reach 30-40 m/s).
Function: High speed throwing, shearing, convection, friction heat generation.
Pot lid and seal
Cast aluminum/stainless steel, with feeding port, spray port, breathable/dust removal port.
Sealing: Double sealing rings, multi-layer skeleton oil seal and oil injection for the main shaft, leak proof powder.
Transmission and Base
Motor+reducer/belt, pneumatic/hydraulic lifting cover, pneumatic discharge.
electric control system
Temperature/time/speed automatic control (PLC/instrument), automatic/manual unloading.
2、 Working principle (mainly hot mixing)
After the material is put into operation, the high-speed blade vigorously stirs to form turbulence, shear, and convection, and quickly disperses.
Self friction+electric heating to raise the temperature (usually to 90-120 ℃), allowing PVC particles to absorb additives, dry, pre plasticize, and increase density.
After reaching the set temperature/time, the material is automatically discharged (often entering the cold mixer for cooling, anti caking, and exhaust).
3、 Main purpose
PVC dry mixing/wet mixing, coloring, drying, plasticizer absorption.
Also used for high-speed mixing, coating, drying, and devolatilization of PE/PP/ABS/engineering plastics, rubber, powder chemicals, dyes, etc.
4、 Performance characteristics
High speed and efficiency: Mix evenly in one pot for 5-15 minutes without any dead corners.
Heating method: self friction+electric heating dual mode, precise temperature control.
Durable material: stainless steel contact parts, blade dynamic/static balance, long service life.
Reliable sealing: The main shaft/pot cover is double sealed, reducing dust.
Automation: temperature control, timing, frequency conversion, automatic discharge, linked cold mixing.
Compact structure: The vertical structure occupies a small area and is easy to clean and maintain.

Competitive Advantage:

1. Higher mixing efficiency and shorter time
Adopting a high shear blade structure, the material has strong turbulence and fast dispersion, and the single pot mixing time is shortened by more than 15% compared to conventional models.
Suitable for continuous and high-yield production lines to increase the overall output of the line.
2. High mixing uniformity and stable product quality
No mixing dead corners, uniform dispersion of additives, powders, and colorants to avoid color differences, uneven plasticization, precipitation, and other issues.
The stability of PVC formula and the qualification rate of finished products have been significantly improved.
3. Accurate temperature control, lower energy consumption
Friction heating+jacket heating dual mode, with small temperature fluctuations to avoid local overheating and coking of materials.
Optimize the matching between blade and motor, resulting in lower power consumption for the same output.
4. Wear resistant and durable, with a long service life
The pot body and propeller blades are made of thickened stainless steel/wear-resistant material, with a polished surface that is not easy to stick and is corrosion-resistant.
The spindle has good dynamic balance, smooth operation, longer bearing and seal life, and low failure rate.
5. Sealed well, less dust, more environmentally friendly
The spindle has multiple sealing structures, which prevent powder leakage and material leakage, making the workshop cleaner.
Can be equipped with dust removal and vacuum exhaust to meet environmental production requirements.
6. High degree of automation and simple operation
Support PLC control, variable frequency speed regulation, timed/temperature automatic discharge, and linked cold mixer.
One click start reduces manual intervention and minimizes operational errors.
7. Reasonable structure, easy to clean and maintain
Large door cover, pneumatic discharge, easy material replacement and cleaning, suitable for multi formula production.
Less maintenance points, easy maintenance, and short downtime.
8. Strong adaptability and wide applicability
Not only suitable for PVC powder, but also for PE, PP, powder chemical, filling modification, etc.
Can be paired with hot and cold mixing units to meet different process requirements.
