Nylon material mixer (plastic or polyethylene) in capacities between 1 and 5 tons is used to mix, dye, dry and homogenize plastic raw materials before the production process (such as the production of nylon film, sacks, or injection parts).
In the following, I will explain the operation of this device step by step and based on the technical structure 👇
⚙️ Structure and main components
Main tank (tank or cylindrical boiler):
It is made of stainless steel or thick iron with anti-wear coating. The capacity is adjusted from 1 to 5 tons according to the production volume.
Impeller:
Designed with a special angle to mix granular or powder materials evenly, without lumping or settling. It usually has 2 or 3 wings and is connected with a strong electric motor.
Electric motor and gearbox: power between 7.5 and 30 horsepower (depending on capacity); Constant torque transmission for uniform rotation of the stirrer axis.
Heating system (if any):
In thermal mixers, an electric element or thermal oil is used to remove the moisture of the material and absorb the color or additive better. The working temperature is usually between 60 and 120 degrees Celsius.
Electrical board and control panel:
To set time, speed and temperature. Some new models have a digital display and PID control.
🔄 How it works
Incoming raw materials (granules or nylon powder, masterbatch, recycled materials)
Set mixing time and speed – usually 5 to 15 minutes
The rapid rotation of the propeller and the creation of a vortex flow spread the materials in all directions and the temperature rises uniformly.
Adding color or additives (Anti-UV, Slip, CaCO₃) to completely mix with the base material.
Emptying from the outlet valve or the bottom valve of the tank into the silo or the extruder device
⚡ Usual capacities and performance
Nominal capacity of the mixing time of the usual engine power
1 ton 5-10 minutes 7.5-10 HP small units or painting materials
2-3 tons 10-12 minutes 15-20 HP mixing recycled materials with masterbatch
5 tons 12-15 minutes 25-30 HP industrial nylon, sack and heavy film production lines
✅ Benefits
High uniformity in the combination of color and additives
Decreasing humidity and improving the quality of the output in the extruder
Relatively low energy consumption
High mechanical durability
⚠️ important points in choosing
Body and propeller material (anti-wear and heat resistant)
Type of drainage system and cleaning time
Compatibility with the type of material (powder, granule, or recycled material)
Existence of electrical safety system (emergency switch and thermostat)
