The introduction of the fertilizer screener

In the process of the fertilizer production,it always need to be granulated,mixed,crushed,and screened and so on.And the fertilizer machine have fertilizer granulator machine,fertilizer mixer machine,fertilizer crusher machine and fertilizer screener machine.Usually,the uniform of the granular influence the fertilizer products,so the process of the screening is very important.So today,this article will introduce for you about the fertilizer screener machine.  
Type of screening equipment:
1.Drum screener machine:Rotary screen is a common equipment in the production of compound fertilizer,which is mainly used for the separation of finished products and reclaimed materials,and it can also realize the classification of products,so that the finished products can be evenly classified.The machine adopts a combined screen for esy maintenance and replacement.It has the advantages of simple structure,convenient operation and smooth operation.It is an ideal equipment for the production of compound fertilizer.
2.Vibration screener machine:The vibrating screen machine is specially designed and developed by our company for screening compound fertilizers.The sieves are divided into two types:single layer and double layer.The mesh is made of high quality manganse steel with simple structure and convenient operation.The size of the grid can be selected according to your requirements.
Screening of raw materials:
Before the raw materials enter the granulation system,due to the large difference in particle size,the sphericity and homogenization will have a greater impact.Therefore,in actural productin,the raw material pretreatment,such as screening,crushing etc,it must first be carried out.This process is one of the important steps to ensure uniform nutrient content,suitable particle size and high granulation rate.
Screen separation of finished products
The semi-finished comound fertilizer after granulation,drying and cooling cannot be directly packaged,on the one hand,because the particle size of the different granulation equipment itself is different.On the other hand ,because the granulated product is in the drying and cooling process.There will be ddifferent degrees of damage,so the granularity of the semi-finished compound fertilizer is very uneven.Morever,with the development of scientific fertilization,high requirements are also placed on the uniformity of finished fertilizers.Therefore,this process needs to be achieved by screening.
