Using the chicken manure or cow manure to make the organic fertilizer,the first step is to ferment the raw materials which uses the fermenting technology to kill the bacterial in the raw materials.The put them into the fertilizer granulator machine to make granulator.So why we making granulator after fermenting?
The granulation production of rotten materials is generally coarse in texture,poor in cohesiveness and difficult in granulation,which has long been the bottleneck of organic fertilizer production.Organic fertilizer granulation has made a breakthrpugh after the traditional extrusion and disk technology,which using the roller press granulator and disk granulator.The new granulation equipment adopts rotary drum or spray technology which we designed the rotary drum granulator.
Extrusion granulation:The rotten materials are combined with a certain amount of inorganic fertilizer,which are extruded or roller 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 prouct has high water content,coarse columnar particles,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 equipment is easy to wear.

Disc pelletizing:almost all organic materials can be pelletilized by disc granulator 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 humidifer,wrapped with the disc,and then dried and screened in the fertilizer manufacturing process.The features of the process are:the selection of materials is not high,but it needs to be dried and crushed first,the process is tedious;the spherical particles have low granulation rate and poor appearance;the production capacity is moderate,and the power required is small compared with the same period last year.
Rotary drum granulation:the process with rotary drum granulator  through the design of a unique granulatior in the drum,using the principle of material particles collision and inlay,to achieve the direct granulation of high humidity organic materials.Its characteristics are；wide range of application,no special requirements for materials;simple process,eliminating the two pre-treatment processes of drying and grinding,and direct production;spherical particles,high granulation rate,good product appearance.
