What is the basis for selecting the crusher model?

For organic fertilizer production lines, raw materials from a wide range of common livestock manure, crop straw, organic domestic waste and so on. When dealing with raw materials such as livestock and poultry manure that contain more fiber and have higher humidity, a crusher with strong shear and extrusion functions should be selected. Because the fiber components need to be broken effectively, and the high humidity requires the equipment to have good anti-clogging performance. For example, some specially designed two-axis shear shredders can strongly shear and squeeze the material through the relative rotation of the upper and lower rollers, breaking the fiber bundle, while its wide feed port and special discharge structure can prevent wet material clogging.

If the crop straw is the main raw material, because of its relatively hard texture and has a certain toughness, it is necessary to choose an impact crusher. This crusher uses a high-speed rotating hammer to hit the straw violently, causing it to break into small segments. Moreover, in order to meet the needs of large-scale production, in the fertilizer production line, different specifications of impact crushers can be selected according to the output requirements, from small household types to large industrial grade equipment, and its crushing efficiency and processing capacity differ greatly.

When considering matching with the subsequent fertilizer pelletizing machine, if the flat die granulator machine is used, because of its relatively fine and uniform particle size requirements for raw materials, it is necessary to choose a grinder with finer particle size after crushing, like the ultrafine mill can crush raw materials to a high fineness, providing a high-quality raw material basis for flat mold pelletizing. For the disk granulator, its tolerance is relatively high, but the raw materials also need to reach a certain fineness to ensure the quality of particle molding, at this time you can choose a general medium-sized crusher, both to meet the production requirements, but also to take into account cost effectiveness. In short, according to different raw material characteristics and subsequent granulation process, reasonable selection of crusher model is the key to ensure efficient operation of fertilizer production line.
