Product Introduction:
potassium magnesium sulfate fertilizer granule making machine usually use double roller press extrusion granulator.The Double roller press granulator is the main equipment for processing powders into particles with a size of 2-30mm. Its working principle is that various dry powder materials are fed from the top of the equipment. After degassing and pre-pressing by a screw, the materials enter the counter-rotating rolls. Under the extremely large extrusion force of the counter-rotating rolls, the materials undergo plastic deformation and are compressed into flakes. Then, through processes such as crushing, granulation shaping, and screening, the flake materials are turned into granular products.
Features and Advantages:
The Double roller press granulator belongs to dry granulation, which does not require a drying process. This saves energy, reduces the investment and operation costs of drying equipment. It has good fertilizer efficiency, high granulation density, rich organic matter content, and there is no discharge of "three wastes" (waste gas, waste water, and industrial residue) during the production process, meeting environmental protection requirements. The equipment has a relatively simple structure, and is convenient for operation and maintenance.
Disadvantages: It has high requirements for the particle size and humidity of the raw materials. The raw materials need to be pre-treated in advance to ensure the granulation effect. The extrusion rolls of the equipment are prone to wear and need to be replaced regularly, which increases the production cost to some extent.
Main process equipment:
Raw material preparation
- Select natural minerals or chemical raw materials containing elements such as potassium, magnesium, and sulfur. For example, potassium ore (such as potassium feldspar, etc.), magnesium ore (such as magnesite, etc.) and sulfur-containing compounds (such as sulfuric acid, etc.). These raw materials need to be pretreated, such as crushing and grinding, to achieve a suitable particle size for subsequent reactions.
- Extrusion granulation: The potassium magnesium sulfate fertilizer material is fed into the double roller press extrusion granulator, and the material is pressed into granules by mechanical extrusion. The extrusion granulator usually has different molds, which can produce granules of different shapes and sizes as needed. The granules produced by this method have a higher density and high strength, and are suitable for the production of large granules of potassium magnesium sulfate fertilizer, but the equipment investment and operating costs are relatively high.
Drying and Screening
- The granulated potassium sulfate magnesium fertilizer particles contain a certain amount of moisture and need to be dried to reduce the moisture content of the particles and improve the stability and storage performance of the product. Drying is usually carried out in drying equipment, such as rotary dryers, fluidized bed dryers, etc. The dried particles are screened by screening equipment to separate the particles that do not meet the particle size requirements and return to the granulation process for reprocessing to ensure that the particle size of the product meets the standard requirements.
Packaging
- After drying and screening, the potassium sulfate magnesium fertilizer particles can be packaged. According to the purpose and sales requirements of the product, choose appropriate packaging materials and packaging specifications, such as plastic bags, paper bags or ton bags, etc. for packaging, so as to facilitate storage, transportation and sales.
Application-Raw Materials:
The raw material of potassium magnesium sulfate fertilizer is a multi-element potassium fertilizer. In addition to containing potassium, sulfur, and magnesium, it also contains elements such as calcium, silicon, boron, iron, and zinc. Potassium sulfate or potassium chloride is compounded with magnesium sulfate and other substances through a certain process. It can be made by directly extracting or removing impurities by physical methods using salt lake brine or solid potassium-magnesium salt ores, such as extracting potassium magnesium sulfate fertilizer from the picromerite ore in salt lakes. The Double roller press granulator can be used in the granulation process of the compounding technology.
