Extruder parts - hopper

The hopper in the extruder accessories is a device used to store and provide the raw materials required by the extruder. It is of great significance to ensure the stability of raw material supply and production efficiency. Reasonable selection and use of hoppers can improve the overall efficiency and product quality of the production line.

Attributes

1. The hopper is usually made of stainless steel or wear-resistant plastic to ensure durability and corrosion resistance to chemicals.
2. The internal surface may be specially treated to prevent raw materials from adhering and accumulating.
3. The design is usually oval or square to facilitate the uniform flow of raw materials and stable installation of the hopper.
4. It may be equipped with anti-skid or anti-vibration facilities to ensure stability and safety during raw material delivery.
5. Depending on the production capacity of the extruder and the raw material consumption, the capacity of the hopper can be selected in different ways, ranging from small to large.

Functions

1. The main function is to store and provide plastic pellets, powder or granular raw materials required by the extruder.
2. The hopper is usually located above or on the side of the extruder, and the raw materials are transported to the feed port of the extruder by gravity or auxiliary equipment.
3. The design may include a protective cover or sealing device to prevent external contaminants from entering the hopper and maintain the quality and cleanliness of the raw materials.
4. The design of the hopper usually takes into account easy cleaning and maintenance to ensure operational hygiene during the production process and long-term stable operation of the equipment.

Features

1. The hopper is designed to be wear-resistant and corrosion-resistant, and can stably carry and transport various raw materials for a long time.
2. The design takes safety into consideration to prevent raw materials from leaking or the hopper itself from tipping over or being damaged, ensuring the safety of operators and equipment.
3. It can be customized and configured according to different extruder models and production needs to meet different production requirements and environmental conditions.

Applications

1. Mainly used in the production process of extruding various plastic products, such as pipes, films, profiles, etc.
2. In the rubber industry, it is used to transport and store rubber particles or granular raw materials, such as rubber tubes and seals.
3. In food processing, it is used to store and transport various food raw materials, such as flour, grains, etc.
