[0002] Chemical fertilizer, referred to as compound fertilizer, is a fertilizer made by chemical and / or physical methods that contains one or several nutrients required for the growth of crops. The production of compound fertilizer requires the addition of various raw materials. The raw materials for compound fertilizer production will form lumps after transportation and long-term storage. The lumps of compound fertilizer raw materials need to be crushed before compound fertilizer production.
