1. Chemical Industry
Raw material transportation: In chemical production, it is often necessary to transport various powdered and granular raw materials, such as fertilizer raw materials, plastic particles, pigments, etc., from storage containers to reactors, mixers and other equipment. For example, in the plastic production process, the screw feeder can accurately transport plastic particles such as polyethylene and polypropylene to the injection molding machine hopper to ensure continuous production.
Batching: Chemical product production often involves the mixing of multiple raw materials in proportion. The screw feeder can accurately control the delivery amount of each raw material according to the preset program to achieve automatic batching. For example, in paint production, different pigments and fillers can be accurately delivered to the mixing equipment according to the formula requirements.Auxiliary Equipment 2. Food Industry
Raw material transportation: In food processing companies, screw feeders are used to transport various food raw materials, such as flour, powdered sugar, grain particles, etc. In the bread making workshop, flour can be transported from the storage bin to the dough mixer to ensure a smooth production process.
Additive delivery: Food production often requires the addition of a small amount of flavoring agents, preservatives and other additives. The screw feeder can accurately control the delivery amount of additives to ensure the stability of food quality. For example, in beverage production, sweeteners, flavors and other additives are delivered to the mixing tank in proportion.Feeder
3. Pharmaceutical industry
Delivery of pharmaceutical raw materials: In the pharmaceutical process, various powdered and granular pharmaceutical raw materials, such as APIs and excipients, need to be delivered to different production links such as mixing, granulation, and tableting. The screw feeder can deliver in a closed environment to avoid contamination of the raw materials and meet the hygiene requirements of pharmaceutical production.Belt Conveyor Pharmaceutical packaging link: Before packaging the drugs, the screw feeder can deliver the granules from the storage container to the packaging equipment to realize the automated packaging process. For example, the capsules are delivered to the hopper of the capsule filling machine.
4. Plastic industry
Injection molding: In the injection molding production of plastic products, the screw feeder delivers the plastic granules from the silo to the barrel of the injection molding machine. By controlling the feeding speed and amount and coordinating with the working rhythm of the injection molding machine, the injection molding process is ensured to be stable and the molding quality of plastic products is improved.Screw Conveyor Plastic granulation: In the plastic granulation production line, the screw feeder conveys recycled plastic waste or new plastic raw materials to the granulator, and produces new plastic granules through processes such as melting and granulation.
5. Feed industry
Raw material transportation and batching: Feed production requires bulk raw materials such as corn, soybean meal, wheat bran, and additives such as vitamins and minerals to be mixed in a certain proportion. The screw feeder can convey these raw materials to the batching bin or mixer respectively to achieve precise batching and ensure the stability of feed nutrients.belt cobveyor
Finished product transportation: After the feed production is completed, the screw feeder can convey the granular finished feed to the packaging equipment or storage bin for subsequent packaging and storage.
6. Building materials industry
Powder transportation: In the production and use of building powders such as cement, lime, and gypsum, the screw feeder is used to transport the powder from the storage warehouse to the mixing equipment or transport vehicle. For example, in a ready-mixed concrete production plant, cement is transported from the silo to the concrete mixer.
Additive delivery: Sometimes a small amount of admixtures, such as water reducers, retarders, etc., need to be added in the production of building materials. The screw feeder can accurately control the delivery amount of these additives to improve the performance of building materials.
Performance Characteristics:
1. High conveying efficiency: The screw feeder can convey materials continuously and stably, and can lift a large amount of materials to a specified height in a short time to meet the needs of different production scales. Its conveying speed can be flexibly adjusted by adjusting the motor speed or changing the reducer transmission ratio, and it has strong adaptability.
2. Wide range of applications: Whether it is powdered flour, cement, granular plastic particles, grains, or small pieces of materials, as long as they have a certain fluidity, the screw feeder can usually do it.
3. Good sealing: The closed structure of the barrel isolates the material from the outside world during the conveying process, effectively preventing the material from leaking and flying, avoiding moisture and pollution, ensuring the quality of the material, meeting environmental protection requirements, and maintaining the cleanliness of the workshop.
4. Easy installation and maintenance: The overall structure is relatively simple, the footprint is small, the installation is flexible, and it can be flexibly arranged according to the spatial layout and process flow of the production site. Daily maintenance mainly focuses on the inspection and maintenance of components such as the screw, barrel, and drive device. The maintenance difficulty is low and the maintenance cost is not high.
5. The conveying distance and height are adjustable: By adjusting parameters such as screw length, speed and barrel height, the screw feeder can adapt to different conveying distance and height requirements. In some large production sites, materials can be conveyed to more than ten meters or even higher.
