Review: How to Use a Hammer Mill (Part 1)

hammer mill feed grinder

1. On the premise of meeting the requirements for livestock and poultry breeding, sieve pieces with larger sieve diameter should be selected as far as possible.

The effect of the sieve diameter on the power output of the crusher mill is very significant, and it also directly affects the fine crushing rate of the crushed feed (average diameter of the feed particles). Fineness of feed M = (0.25~0.33) d. The larger the sieve diameter, the higher the power output, but the coarser the crushed material. In general, when crushing concentrated feed, the sieve diameter starts from d = 2mm, and each increase of 1mm can increase productivity by 20%~35%. Conversely, the smaller the sieve diameter, the finer the feed will be crushed, but the productivity and power output of the machine will also be significantly reduced. Therefore, on the premise of meeting the requirements of livestock and poultry breeding, a sieve with a larger hole diameter should be selected as much as possible.

2.The feeding amount should match the air flow through the sieve holes.

Different types of hammer mill feed grinder require different feed rates, which directly affect the crushing efficiency. When the feeding amount is greater than a certain value of the air flow rate passing through the sieve holes, the materials will be stacked on the sieve surface, causing the sieve holes to block to varying degrees. The circulation layer in the pulverization thickens the resistance acting on the rotor, resulting in grinding efficiency. decline. Therefore, only when the feeding amount meets the design requirements of the crusher, the power consumption is minimized, the productivity is maximized, the motor is not overloaded, and the user can obtain a satisfactory crushed product.

3. Pay attention to the balance of the machine

The animal cattle poultry cow fish feed hammer mill  is a high-speed rotating machine that has undergone dynamic and static balance tests at the factory. After a period of use, when the edges of the hammer piece wear to 1/2 of the width of the hammer piece, the edge change or turning must be performed in place. When the blade of the axially fed crusher primary cutting device is worn, the adjustable head can also be used. When new hammer blades need to be replaced, they should be re-weighed and ensure that the mass difference of each group does not exceed 5g, to avoid affecting the balance of the machine and generating vibration and noise.

4. Pay attention to the tightness of the transmission belt

The tightness of the drive belt of the shredder can be adjusted by moving the front-back position of the motor on the machine base. In order to avoid the drive belt slipping, it can be loosened to increase the wrapping angle.
