Machine list

Belt conveyor

1) Belt material: PVC

2) Speed adjusted by inverter, synch running with agglomerator

3) Height adjustable

4) Equipped with wheels

5) Equipped with tightening device

6) Metal detector for option

Agglomerator

• Double-layer cutting- disk, patent design, more efficient in feeding.
• Special arrangement of blade & feeding mouth, output is increased by 10%-20%
• Hydraulic Opening and Hydraulic Lifting, safe and easy maintenance
• Our method of cooling wall of agglomerator: by air and water cooling system, No need to add water into the agglomerator.

• Double-layer cutting-disk

Output is increased by 10%-20%！

Double-layer cutting-disk:

Double-layer cutting-disk design, the upper cutting-disk is preheating, the lower cutting-disk increases the compression space, increases the friction coefficient, the temperature rises fast, the feed is stable, and the output is increased by 10%-20%, especially for raw materials with low bulk density.

Single screw extruder (First stage)

1^st extrusion, 1^st filtering

• Gearbox: high quality Chinese brands or based on customer’s request
• Frequency inverter: Siemens brand
• Screw & barrel: 38CrMoAl, Nitride with thickness 0.4 ~ 0.7 mm, Polish
• Heater: Ceramics + stainless steel cover
• Vacuum pump exhaust, double exhaust
• Self-protective system:

Over current protective of motor

Over pressure protective of screw

Over temperature protective of motor

Low & over temperature control of extruder

• Screw & barrel are specially designed by our engineer according to decades years’ experience for good plasticizing effect & capacity.

Screen changer

Multiple choices for different materials.

• Material for mold body: 40Cr
• Nitriding and polishing of runner surface
• Pressure and temperature control
• When pressure is nearly reach alarm value, hydraulically change to another station.
• High filtering effect, realizing non-stop screen changing
• No leakage, automatic gap compensation

Single screw extruder (Second stage)

2^nd extrusion, 2^nd filtering, to achieve better granule quality

Water-ring cutting system

Quantity of Blade: 2-4, SKD-11

Speed controlled by inverter

Material of die head: 38CrMoAlA

Material of water ring cover: Stainless steel 304

Horizontal design with linear guide, easy operation and maintenance.

Pneumatic adjustment, to make cutting blades and die-face soft touch, in order to achieve 100% contact between the blade and die head, to avoid die face damaged.

Dewatering Vibrator

1.Linear vibrating screen uses vibrating motor as the vibration source, so that the pellets are thrown up on the screen, and move linearly forward. Several sizes of screens are equipped for pellets discharging from their respective outlets.

2.Linear screen fully enclosed structure, no dust and overflow, automatic discharge, etc., more suitable for 24-hour assembly line operation.

3.Linear screen by low energy consumption, high output, simple structure and easy maintenance.

4.Combination of filtration and dehydration, high efficiency and power saving.
