How should the extruder be selected?

Relying on a professional team of puffing technology experts, Dingrun has been committed to the research and development of extrusion equipment, and is a professional manufacturer of extrusion equipment. The company has a complete range of manufacturing equipment, diverse products, and complete supporting series. Customers can purchase all the equipment they need in one stop. At present, it is the main professional manufacturer, manufacturer and R&D manufacturer of extrusion puffing equipment and its supporting equipment in China.

Selection of twin-screw extruder

1. The puffing effect of the puffing machine

For aquatic feed, the good puffing effect is that the particle forming rate is more than 99%, the particle pulverization rate is less than 1%, the particle floating rate (sinking rate) is 100%, the particle size is uniform, the color is consistent, and it has good water resistance. ; The floating type aquatic feed is kept in the water for 10 hours, and the sinking type aquatic feed is kept in the water for 3 hours without collapsing.

2. The service life of the extruder

Extrusion machines from different manufacturers have different service lives due to different structural characteristics and materials used. Therefore, when choosing an extruder, special attention should be paid to the wear resistance of some wearing parts, and whether its structural design is reasonable and whether it can achieve the purpose of reducing screw wear; in addition, when choosing an extruder, it is necessary to Consider whether the machine can really achieve the purpose of saving energy and reducing consumption. For the raw materials that have not passed through the ultrafine powder, the wear of the wearing parts will be more serious, especially the twin-screw extruder. In this case, it is more reasonable to use the single-screw extruder.

3. Control method of extruder

Most of the extrusion processing is manual or semi-automatic. The quality of the extruded product has a lot to do with the quality of the operator. The artificial control of the feed, the speed of adding steam and water, and the temperature of the product will cause the quality of the granular product to be unstable. , especially the non-uniformity of moisture, so that the moisture content after drying cannot reach the target, producing unqualified products, which brings great economic losses to production. The fully automatic control method adopts advanced computer to control the flow of materials, water and steam, automatically adds according to the settings, and implements an alarm for all faults, eliminating the influence of human factors related to the operation of the extruder and the unavoidable fluctuation of product quality.

host configuration

Full combination screw

The fully-combined segmented screw can be adjusted and combined according to the state of the material to adapt to a wider range of raw materials. For long-term use, only one section needs to be replaced, saving the cost of maintenance vehicles.

Barrel wear bushing

The alloy wear-resistant bushing is added inside the barrel to increase the service life of the equipment and save the cost of equipment maintenance in the later stage.

Reinforced high torque case

High torque reinforced box structure, stronger output power, immersion lubrication system and fiberboard box heat dissipation, increase the service life of the box.
