Manufacturing technique

• The current domestic production technology of small devices for aggregate method. It is the powdery fertilizers such as urea,MAP,DAP,KCL and other mixed

  Aggregate method of simple production process, short process, easy operation, product variety, the investment province, mount fast and convenient to replace, as well as good benefits. Especially as secondary processing of basic fertilizer, Cooperate with the soil testing fertilization, Scientific fertilization, To reduce the cost of agricultural field, Increasing agricultural benefit and popular.

  Explain of craft process

• Aggregate method, Basic process is divided into raw material crushing device, metering, mixing, granulation, drying, cooling, screening, envelope, packaging process. The process description is as follows now:  MAP (powder), potassium chloride and organic matter by the dog-house respectively by the belt into the system of speed measurement process, After crushing, all raw materials by mixing by mixing with the elevator into the granulator, the steam from the plant into boiler room of the drum granulator. The tail gas by granulation exhaust fan out of pelleting  machine .  Granulator granulation with the solid material into a ball .

  Granulation material temperature:60-80°C

  Granulation material water:5.5–8.5%

   

• In good operating condition, the pelleting machine export grain of granulating rate generally 50-80%,Belt conveyor after granulation materials by Chen sent to dryer. In the dryer, and flow of materials and thermal drying to water cut less than 2%,Heat flow is from coal burning in the furnace, and according to the dryer outlet gas temperature control of combustion furnace with coal, water content of dry products will change along with the change of the drying temperature. So, adjust the volume of coal is an important means of control product moisture content.

   

  This device adopts two into the wind with the wind, processes by jet fan into the airand the hot blast stove coal combustion heat generated after mixing into the dryer, Exhaust after pumping, induced draft fan for drying into the dry dust removal chamber dust removal. After the dust exhaust generally can meet relevant national environmental standards, Does not contain the dust exhaust gas from the chimney into the high atmosphere.

•  

  Out of the dryer tail of dry material automatically fall into cooling material hoist hopper,

  However, one after another into the cooling machine cooling, coarse and fine screen vibrating screen vibrating screen for screening. Large particles with coarse grain after return product back to the crusher crushing of belt conveyor,Small particles with fine belt machine back to the granulator as masterbatch to granulation. Qualified fine sieve particles automatically fall into capsular material hoist into coated machine processing.

  Cooling process with air for cooling, cold air from the cooler backend to and material flow. Like the air after cooling and drying exhaust, dust removal by end out after cooling dust chamber, without dust exhaust the upper part of the chimney into the high atmosphere. Coated particles by the finished product after the elevator into the storage hopper of automatic packing machine, after packing into the shipping department.
