Additive dosing and gain-in-weight as central systems or individual units

gravimetric blender
1.When the metering valve is started, the hopper metering valve opens according to the time value calculated by the preset weight value and the unit feeding volume of the metering valve. When the feeding time is up, the metering valve closes and the weighing pan is checked. If within 2.The specified error range,it goes to the next hopper for weighing and check;
When the raw materials in all the hoppers have been weighed and checked, they will fall into the mixing bucket for stirring and mixing. When the mixing time is up, they will be automatically discharged into the bottom storage hopper.

Masterbatch doser
The signal from the control box is transmitted to the motor, and the motor starts operation to drive the screw rod to rotate through the coupling. The color master batch in the hopper falls into the screw rod, and then is squeezed by the screw rod, and conveyed to the base by the screw rod. A weighing sensor is used to precisely contral the output of the color master batch to realize the proportional addition of the color master batch, so as to achieve the purpose of accurately metering and conveying the color master batch.

Dehumidifying dryer
The hot and humid air returned from the drying bucket is cooled and blown into the honeycomb rotor.The moisture in the air is absorbed by the rotor and then desorbed by the regenerated heated air.The two air flows act on the rotor at the same time. As the rotor rotates, the moisture in the air is continuously absorbed and desorbed for discharge, and finally air with a stable low dew point is formed,which is heated to the drying temperature required by the plastic material and then blown into the drying bucket to form a closed circulation loop.

Verical batch mixer
It uses the screw blades to generate vortex to achieve the purpose of mixing. The raw materials to be mixed will be drawn into the stirring screw installed in the center by the vortex generated at the bottom of the mixing bucket, and then rolled up to the top along the screw rod and drge. In this way, uniform mixing can be completed in a short time.
There are currently 4 standard models with a loading capacity of 500-3,000kg,which can meet diffenent customer needs.Widely used in the mixing and stirring of granular materials.

Insulation dryer
The insulation dryer is suitable for centralized drying of granular, which can be used in the centralized feeding system of granular, can also be used in the unified drying system of raw materials of serval machines. It working principle is in the course of raw material processing , the air blown out by the drying fan is heated by the electric heating pipe and becomes high-temperature dry air. After passing through the unique lower blowing pipe,the hot air is evenly dispersed in the insulation bucket to dry the raw materials ,and the moisture in the raw materials in the bucket is evaporated and blown put ,thereby achieving the purpose of removing moisture in raw materials .

compound mixing

Compound mixing
The high speed mixer is generally used in a vairety of powder material mixing ,the motor drives the paddle to rotate at high speed, the materials(or granular ,liquid and powder combination materials) in the mixing cylinder under the action of paddle while do circular motion along the cylinder wall,  also clambing on the wall to reach a certian height, it will toward the center cylinder body to do the downward motion,in this processm all kinds of raw materials have strong convection mixing with each other. At the same tiem, due  to the stirring of the paddle, the velocity difference between materials is gengerated, which strengthens the effect of shear mixing;
The powder after the high speed hot mixing and due to frictional heating , mixture tempeature reached 100℃ above,when the powder discharging to the cold mixer and through forced cooling, proceed the high efficiency cooling ,Mconvey cold mixer of cylinder block and cylinder cover are set with water ring, and configure the forced cooling water pump to accelerate cooling effectm while the cold mixer works, the high speed hot mixer can carry out the second batch of mixing work, the mixing cycle of the cold mixer is shorter than the hot mixer, to ensure that the second batch of raw materials can be discharged into the cold mixer in time after mixing.
