China Professional Lab Plastic Extruder Manufacturer — Granuwel

Laboratory twin screw extruder is mainly used in the research and development of polymer plastics, mainly for universities, enterprises and research institutes. The main feature is that the screw diameter is small, which greatly reduces the use of materials in the application and development.

Lab Extruder For Sale

The laboratory twin-screw extruder is mainly used for experimental teaching in laboratories and research institutes of various colleges and universities, or research and development of new products in plastic processing plants, so as to understand the performance of raw materials and auxiliary materials, formula and batching operation.

The extruder adopts the form of twin-screw in order to fully stir the materials so as to achieve the best mixing and plasticizing effect. The twin-screw extruder is composed of frame, main motor, coupling, transmission box, feeding system, mixing and extrusion system, heating and cooling system, lubrication system, vacuum exhaust system and electrical control system.

The laboratory twin-screw extruder granulation line is mainly composed of twin-screw extrusion, die head, cooling unit, drying unit and granulation unit. The cooling unit has two forms: water cooling and air cooling.

Generally, the water cooling mode is to configure the water tank and the drying unit; Air cooling is to configure conveyor belt.

The granulation method depends on the performance of the material. The material is plasticized by the extruder and extruded into a round strip. After water cooling or air cooling, the round strip is pulled to the pelletizer and cut into cylindrical particles.

Application range:

1. Used for mixing and granulation of materials
2. Plasticization and conveying of materials
3. Blending modification and reactive extrusion of composite materials
4. Mixing and mixing of general materials, engineering plastics, elastomers and other materials
5. Polymer Reinforcement Modification
6. Material dehydration, devolatilization and exhaust

Main Features Of Granuwel Lab Plastic Extruder

Prospective

Experimental twin screw granulation is the research and development tool of many enterprises, and it is the vanguard of new products and new processes.

Versatility

With conveying, plasticizing, refining, cutting, vent, building pressure and extusion and other functions, a device can easily achieve most of the development of new materials.

Flexibility

The "building block" design can flexibly combine screw elements according to the material process requirements to achieve the ideal structure. At the same time, worn parts can be partially replaced to reduce maintenance costs.

Accurate measurement and reasonable feeding method

Equipped with a variety of feeding methods, such as volumetric feeding, weight loss feeding, etc., to ensure strict implementation of the formula, to ensure product quality.

Advanced control system

The extusion machine is equipped with advanced and beautiful control system, and the control components are of good quality and high sensitivity. Touch screen and Siemens PLC centralized control system can also be configured according to customer requirements, which is highly intelligent and easy to operate.

Various pelletizing methods

The system is equipped with a variety of granulation methods, such as water-cooled drawing granulation line, underwater granulation line, and air-cooled hot surface granulation line. It can be configured according to different materials and user requirements.

Unique barrel structure design

The barrel can be designed as the upper and lower split structure, which is fast to open and easy to clean, providing first-hand mixed information for the research and development of new materials.
