There are many factors that affect the production efficiency of poultry chicken feed manufacturing plant. In addition to being directly related to the aperture of the screen, they are also related to the moisture content of the material, the speed of the mill, the distribution density of the hammer, the thickness of the hammer, the degree of new and old used, and the hammer and sieve. The gap size of the net is related to many factors. The production efficiency of the poultry feed grinder machine has a great relationship with its suction system, pulverization process design and the shape of the screen mesh. Therefore, these factors should be considered comprehensively during use. It is a relatively simple way to improve the production efficiency of the crusher by changing the shape of the screen mesh and the crushing process.
1. Mesh hole shape
The more common ordinary horizontal poultry chicken feed hammer mill machine, its screen is almost circular. After the material is hit by the hammer at a high speed, the movement direction of most of the material is the tangential direction of the impact point, and most of the ordinary screen holes are punched. Because the screen has a certain thickness and the hammer-screen gap of the micro pulverizer is small, the particles will inevitably collide with the screen wall and bounce when they exit the screen, causing them to be unable to discharge the screen in time, resulting in low efficiency. Richi Machinery has developed a new type of micro-pulverizer specifically for the micro-pulverization of aquatic feed.
The screen used in this kind of micro-pulverizer is a unique fish-scale shape, the screen hole is protruding, and the opening direction is consistent with the tangent direction of the impact point, thereby improving the angle between the direction of movement of the material and the direction of the screen hole, which is beneficial for powder discharge Sieve is very important to improve the efficiency of the poultry animal feed grinder. Practice has proved that the output of this crusher is nearly 30% higher than that of other crushers of the same type.
2. Secondary crushing process
Reasonable process design is also one of the factors to improve the efficiency of the poultry chicken feed grinding machine. Generally, the feed processing unit adopts a one-time crushing process, and the crushing particle size is mainly controlled by changing the size of the screen aperture. In the one-time crushing process, according to the crushing rules, there will always be a certain amount of fine powder that has reached the particle size requirement, but due to the failure to discharge the screen in time, it will be crushed multiple times in the crushing chamber, which will increase the load of the poultry feed grinder mill. Cause unnecessary efficiency reduction and energy waste. Therefore, the use of the secondary crushing process will obviously avoid this shortcoming. The secondary crushing process is based on the primary crushing process by adding a coarse crusher, such as a poultry feed hammer mill crusher and a grading screen.
For the electric corn animal feed hammer mill grinder for chicken feed that can also be used in the primary pulverization process, the sieve aperture can be larger. After the initial pulverization and re-screening, the fine powder that meets the particle size requirements can directly enter the next process without having to go through the secondary crusher crushes, and the materials that do not meet the requirements enter the secondary crushing link, which can greatly reduce the load of the single crusher and improve its crushing efficiency. Compared with the primary crushing process, the secondary crushing process has two additional equipments, but it can significantly improve the production efficiency and product quality, and reduce the energy consumption by about 25% to 50%. Therefore, this process has been used by many large scale and medium-sized poultry chickens feed mills.
