The plastic granulator is a kind of equipment commonly used to produce plastic granules. The temperature regulation of each area is very important for product quality and production efficiency. The following will introduce in detail the temperature regulation method of each area of the plastic granulator.

Kneading blocks are components installed on the extruder screw. They are used in combination of two or more to mix and disperse materials and improve the mixing effect of the extruder. If you want to achieve a good mixing effect, it is important to choose the right kneading block.

The structure of a twin-screw extruder is very similar to that of a single-screw extruder, but its working principle is very different. In a single-screw extruder, material transportation relies on the friction and viscous resistance of the material, so the residence time distribution is wider. In contrast, the material conveying of the twin-screw extruder relies on the positive displacement of the screw, so the residence time distribution is narrower. The raw materials of the twin-screw extruder are fed through the feed port by a metering feeder. Some additives (such as glass fiber) need to be added through the feed port in the middle of the barrel and transported to the die head by the screw. During this process, the movement of the material varies depending on the screw meshing method and the direction of rotation. This article will introduce the specific differences in their working principles from this perspective.

In the process of extrusion granulation, the feed system plays a key role in the force and coordination between the cutter and the template for the smooth operation of the unit. Let's take a look at the relationship between the feed hydraulic oil pressure and the retract balance system hydraulic oil pressure in the actual production process, and the practical effect after improvement.

Since its introduction, twin-screw extruders have been widely used in the field of plastic modification and are the core equipment in the field of modification. Every modification factory takes good care of the twin-screw extruder, but in daily work, it is inevitable to encounter equipment loss and repair. So in order to avoid or reduce loss, how to repair it after a failure, the editor will introduce to you some tips on extruder maintenance and repair.

As the main equipment for compounding production, the extruder is the most difficult and dangerous to operate. Today, we have sorted out some tips for you to keep in mind during the operation and debugging of the extruder, so as to protect safe and efficient production.

In the ever-evolving plastics industry, the technological innovation of twin-screw extruders has always led the industry's progress. Today, let us explore the latest innovations of twin-screw extruders.

When pure resin is "modified", the more suitable pelletizing method often changes; Examples of pelletizing selection for common modified special materials or masterbatches; Examples of pelletizing selection for the following polymers or modified materials.
