How to choose the fertilizer production line correctly?
Fertilizer production line equipment includes: fermentation turning machine, crusher, feeder, horizontal mixer, organic fertilizer granulator, dryer, cooling machine, screening machine, weighing and packaging machine.
How to choose the fertilizer production line correctly? First, we need to understand how fertilizers are produced. Generally speaking, the production of organic fertilizer and npk production line can be divided into four steps crushing-granulation-drying-packaging. These necessary steps also have more extended procedures, such as mixing, cooling, screening, coating, etc. How to choose the fertilizer production line correctly? Let's take a brief look at it below.
How to choose these production lines usually depends on the raw materials that need to produce fertilizer. For example, in the crushing stage, different crushers are selected according to the moisture content of the raw materials. Generally speaking, for raw materials with high water content, we should choose a semi-wet material crusher for crushing. If it is dry material, such as dry cow dung, sheep manure, etc., we can choose vertical crusher for crushing, if it is to produce npk compound fertilizer, we can choose cage crusher.
In the granulation stage, we usually choose a disc or rotary drum granulator according to the fiber size of the raw material, such as chicken manure. The double roller granulator is used for crude fiber materials, such as sheep manure, straw, etc. During the drying process, if the budget is sufficient, we often recommend that users carry a cooler after the drying process, the main purpose is to prevent the agglomeration phenomenon caused by the overheating of the pellets. In the later stage of granulation, you can choose outer film, polishing and other processes, which belong to the beauty process of finished products, so that the granules are more beautiful, neat and full.
