Industrial milling machines take important position of production and process in agricultural development and are indispensable; besides, milling machine quality is related to fertilizer production quality while hot selling of fertilizer also directly influences the milling machine market, which showing that they two influence and restrict each other. The development of agricultural fertilizer needs innovation and development of milling machines and in return the development of milling machines also needs promotion and help from agricultural market.

Grinding mill has been widely used in agriculture, such as mechanized sowing and reaping, fast and convenient debugging and weeding, increasing production, etc. Taking chemical fertilizer as an example, chemical fertilizers supply nutrition for crops through physical or chemical methods, and common used fertilizers include nitrogen, phosphate and compound fertilizers. Every kind of fertilizer is composed of multiple materials, such as nitrogen fertilizer with nitrogen as component includes ammonium bicarbonate, urea, ammonium sulfate, ammonia water, ammonium chloride and ammonium sulfate; so does other fertilizers. And components of fertilizer can not exist alone in nature but hid in ores and vegetation. Thus the effective components needs to be extracted through crushing and grinding, for instance, ores with much nitrogen can be crushed and ground by Raymond mill to get the effective components. And a majority of agricultural fertilizers are powder so no matter what components contained in fertilizers needs to be processed by grinding machines. Therefore, agricultural development is closely related to industrial milling machines.

Though fertilizers are not a new thing, it’s developing history is short and its appearance is followed up mining machines. Fertilizer is a new progress based on grasping organic ingredients for crop growth and new technologies. So we say that industrial milling machine is the prerequisite for fertilizer’s research and development. And fertilizer must produced according to certain ratio of each elements or it will affect crops’ healthy growth instead of facilitating them. Lets learn some processing technologies of industrial milling machines for common fertilizers:

Nitrogen fertilizer: liquid ammonia and carbon dioxide are used as industrial material. With rich coal resources in China, carbon dioxide mostly comes from coal. Coal milling machine can process raw coal first before production, bring green and environmental friendly burning, which are widely used in production involving coal burning currently.

Phosphate fertilizer:the main materials for phosphate production are phosphorite and sulphuric acid. With rapid development of phosphate fertilizer industry in China, production materials for phosphate fertilizer are getting less and nonrenewable phosphate resource had been one of strategic resources. And crushing and grinding skills are important in reasonable using of phosphorite and needs good grinding machine performance; besides, some phosphorites are inflammable so focus should be put on safety in grinding.

Potassic fertilizer: potassium exists in nature in solid mixture and ranks the 7th place in the earths crust as well as exists in ores, ground and the ocean. But the most economic way is to extract potassic from leopoldite because they can crystallize into glazier's salt by only using certain physical methods and finally glazier's salt could be process into potassic by crushing and milling machines.

Industrial milling machines take important position of production and process in agricultural development and are indispensable; besides, milling machine quality is related to fertilizer production quality while hot selling of fertilizer also directly influences the milling machine market, which showing that they two influence and restrict each other. The development of agricultural fertilizer needs innovation and development of milling machines and in return the development of milling machines also needs promotion and help from agricultural market.
