Generally,when producing the organic fertilizer,we are first to ferment organic raw materials using the fermentation compost turner machine.After fermenting,we will use the fertilizer granulator machine to make granulator using the fertilizer granulator.Generally,rotten materials are coarse in texture,poor in cohesiveness and difficult in granulation,which has been the bottleneck of organic fertilizer production for a long time.Organic fertilizer granulation has made a breakthrough after the traditional roller press granulator and disk granulator technology.
The new granulation equipment adopts rotary drum granulator or spray technology.
Extrusion granulation:the rotten materials are combined with a certain amount of inorganic fertilizer,whih are extruded or rolled into granules by the mould and directly bagged.The process is strict in material selection and pre-treatment,and needs to be adjusted to the appropriate moisture content,fine texture and good adhesion.Its characteristics are:simple process,drying link can be omitted;the product has high water content,coarse columnar particle,good granulation and uniform particle size,but the storage and transportation process is easy to collapse;the production capacity is low,the relative power is large,and the organic fertilizer machine is easy to wear.
Disc pelletilizing:almost all organic materials can be pelletilized by disc fertilizer manufacturing process.After drying and micro grinding,the material is mixed with appropriate amount of chemical fertilizer and sent into the disc.The mixture is sprayed and adhered by the humidifier,wrapper with the disc and then dried and screened.The features of the process are:the selection of materials is not high,but it needss to be dried and crushed firsr,the process is tedious;the spherical particls have low granulation rate and poor appearance;the production capacity is moderate,and the power required is small compared with the same period lase year.
Rotary drum granulator:The prodcess through the deisign of a unique granulator in the drum,using the principle of material particles collision and inlay,to achieve the direct granulation of high humidity organic materials.Its features are:wide application range,no special requirements for materials,simple process,eliminating the two pertreatment processes of drying and grinding,and direct production;spherical particles,high granulation rate,good appearance of goods.
