The compound NPK and NPK blends are multi-nutrient fertilizers containing a certain proportion of all three major nutrients: nitrogen (N), phosphorus (P) and potassium (K). These products allow the crop to be fully applied once in one application. The raw materials for each nutrient will vary depending on the NPK fertilizer production process.
In the production process,one core machine is the granulating machine
,it can make the fertilizer power into pellets,it’s easy for the farmers to apply and store.our factory manufactures a series of granulator machine for the NPK fertilizer production
First is the rotary drum granulator
. it’s commonly used in the production line. It is typically suitable for large scale production. Granulation rate is high; it’s made with special rubber lining or acid resistant stainless steel lining in the barrel, which can automatically remove the scar and tumor. At the same time, the traditional scraper device is no longer used. The machine has the characteristics of high granule strength, beautiful appearance, simple operation, low energy consumption, corrosion resistance, long service life, uniform drying and convenient maintenance, etc. It is a good choice in the industry.
The roller press granulator
is popular among the customers. We design new type of two rollers based on our years’ production experience. it’s more stable and powerful. It is widely used in the fertilizer production, feed production and chemical industry for granulating powder material. The machine adopts to no-drying technology, can granulate powder into pellets at normal temperature, and form one time; with reasonable structure design, stable and reliable operation, convenient operation and maintenance, and less investment, quick effect, considerable economic benefit characteristics and so on. It’s deeply liked by the clients.
