Screw conveyors are used in various sectors of the national economy such as grain industry, building material industry, chemical industry, machinery manufacturing, transportation and so on. The screw conveyor is mainly used to convey various powdery, granular and small block materials. Chemicals such as fertilizers, and bulk cargoes such as coal, coke, and ore. The screw conveyor is not suitable for conveying materials that are perishable, viscous, bulky and easy to agglomerate. In addition to conveying bulk materials, screw conveyors can also be used to convey individual items. The screw conveyor can complete mixing, stirring, cooling and other operations while conveying materials. In ports, screw conveyors are mainly used for unloading trucks, unloading ships and horizontal and vertical transportation of bulk materials in warehouses.

With the development of modern aquaculture and feed industry, the proportion of pellet feed in the entire feed industry has increased accordingly. At present, pellet feed is widely used in large and small farms. People who have been in contact with feed processing plants should know that the processing technology of feed pellets is a very complicated and tedious process, and operators should pay special attention during the production and processing process. Next, I will introduce some prohibited operations in the work of pellet feed machines. 1. It is strictly forbidden to start the pellet feed machine when materials are loaded in it. Before starting the machine, all the materials in the machine should be cleaned up before starting the machine. 2. During the operation of the machine, the operator shall not open the die cover and side cover of the pellet machine without authorization. 3. It is strictly forbidden to overhaul any part of the machine without turning off the switch. 4. If there is a jam phenomenon when the pellet feeder is working, it is strictly forbidden to use hands or iron bars to clear the blockage. Instead, clean up the clogged debris after shutting down the power supply. 5. It is strictly forbidden to use other currents that exceed the rated current of the pellet feed machine to start the machine. The operation of the above steps is strictly prohibited when the pellet feed machine is used. Only in this way can safe production be ensured and profits for enterprises and individuals.

Pellet mills and pulverizers are the key equipment in feed production, and their functions and configurations directly determine the value of the feed production line. Under the same formula and process, whoever can improve the comprehensive efficiency of the pulverizer and pelletizer can win direct economic benefits for the feed factory. Therefore, how to maximize the function of the pulverizer and pelletizer, reduce the production cost per ton of material, and improve the feed yield and feed quality.
