The process design of feed machinery is actually a highly comprehensive task, as it not only includes technical requirements, but also takes into account economic and artistic requirements. The scope of process design work for feed machinery mainly includes the main workshop, direct or indirect production parts of various warehouses, selection of process specifications, formulation of processes, calculation of process parameters, and selection of process equipment.

Usually, in the design process, it is important to choose the appropriate process flow and equipment as much as possible to ensure yield, quality, and energy conservation. Moreover, the designed production capacity of feed machinery should be 15% -20% higher than the actual production capacity to ensure the continuity of the process flow. The details included include:
1. Materials that do not need to be crushed do not enter the crusher;
2. The discharge of the crusher adopts negative pressure mechanical suction;
3. The cake blocks are first roughly crushed with an ice crusher, and then crushed with a grinder.
The selection principles for feed machinery production equipment mainly include:
1. The production capacity of the equipment should meet the process requirements, and its performance should meet the needs of the formula. The unit product should have low power consumption, no noise and dust exceeding the standard, reliable operation, convenient use and maintenance, durability, and appropriate price;
2. Equipment that adopts applicable, mature, economical, and standardized technology.

Overall, the main selection criteria for feed machinery should be based on production capacity, matching power, and structural parameters. In addition, installation, use, and maintenance requirements should also be considered. The selected equipment scheme can be optimized using tips and breakeven analysis, with the main equipment being the main equipment.
