What Are The Raw Materials Suitable for NPK Fertilizer Granulator?

일반적으로 말하면, NPK fertilizer contains at least two or three nutrients (질소, phosphorus and potassium). It has the advantages of high nutrient content, small side effect and good physical properties.

Raw materials for NPK fertilizer production are mainly divided into three categories, including some fillers like clay.

  1. Nitrogen fertilizers: 염화 암모늄, 황산 암모늄, 요소, 질산 칼슘, 등.
  2. Potassium fertilizers: 염화 칼륨, 황산 칼륨, plant ash, 등.
  3. Potassium fertilizers: (무거운) 칼슘 슈퍼 포스페이트, calcium-magnesium phosphate, phosphorite powder, 등.

맨 위 2 Granulation Techniques for NPK Fertilizer

NPK compound fertilizer granulation technology can be divided into wet 그리고 건조 과립. The distinction between them is whether or not the liquid solution is used. Dry granulation does not require the use of liquid solutions such as water or binders, whereas 젖은 과립 must add liquid binders to the powder mixture.

Dry Granulation — Extrusion Granulation Technology

Due to the production of NPK fertilizer without water and binders, the traditional dry granulation technology is extrusion granulation. In the extrusion granulation process, high pressure makes solid materials polymerize into powder and squeeze between rollers to make fertilizer granules.

All finished fertilizer pellets do not require drying and cooling and can be packaged directly. 결과적으로, the dry granulation method and associated equipment make up a small production line capable of forming a continuous, mechanized, and automated production with a certain capacity.

Wet Granulation

Compared to dry granulation, the pellets processed by wet granulation with high moisture content, so you need subsequent handling of drying, cooling and solidification. The equipment used for the wet granulation process are 로타리 드럼 세금질 그리고 디스크 입력기.
