Chengxiang Disc Granulator For Sale, NPK Fertilizer Machine
Npk compound fertilizer production line: How is compound fertilizer produced? Of course, it is produced through npk fertilizer machine. For example, the disc granulator. The disc granulator of Chengxiang Heavy Industry has the advantages of high granulation rate, good granules shape, high granules hardness, suitable for a variety of materials, environmental protection and energy saving, and low noise. Let’s take a look at Chengxiang’s disc granulator.
Structure of Chengxiang Disc Granulator
1. Granulator disc: The granulator disc adopts an overall arc design, and the bottom of the granulator disc is also reinforced by multiple radiating steel plates, which are durable and non-deformed, and the disc body is strong and durable, with a high granulation rate and good granules forming.
2. Adjustment part: The granulator plate is the most important part of the whole machine. Its entire center of gravity is installed on the adjustment part.
3. Frame part: The transmission part and the rotating working part of the whole structure are supported by the frame, and the frame of the machine is welded with high-quality carbon channel steel.
4. Transmission part: The transmission part of the whole machine is very important, and the whole granulation work is completed through it.
5. Automatic cleaning part: This part is installed above the granulation tray, and the lower frame shape is equipped with an automatic cleaning plate to remove the material stuck to the disc body during the production process.
6. Our company specializes in the production and sales of fertilizer equipment. The disc granulator is sturdy and durable, and the product has passed ISO quality certification and CE certification.
Working principle of disc granulator
The disc granulator is mainly composed of a swash plate and a base, with adjustable angles. During the granulation process, the mixed materials are transported to the top of the disc by the conveyor and are continuously and quantitatively added to the disc. The material in the disc is adhered by the adhesive under the spray and wrapped into granules. As the disc rotates, granules gradually form. Because the Chengxiang disc granulator has significant classification capabilities, the formed large granules continuously flow out from the bottom of the disc. The small granules continue to be granulated with the newly added materials. It has the characteristics of uniform granulation, less granules return material, and large production capacity.
Process of disc granulator in compound fertilizer production line
1. Raw material preparation: First, according to the formula requirements of compound fertilizer, various raw materials are accurately weighed, such as urea, ammonium phosphate, potassium chloride and other basic fertilizers, and may also include some fillers and additives, such as clay, trace elements, etc. The selection and ratio of these raw materials are determined according to the nutrient content and function of the target compound fertilizer.
2. Mixing: The weighed raw materials are crushed to make the granules size of the raw materials reach the appropriate range. The crushed raw materials are put into the mixer and fully mixed to ensure that the various components are evenly distributed.
3. Granulation: The material rolls continuously under the rotation of the disc and gradually forms granules. The speed of the disc is generally controlled at 15-30 rpm, which can make the material have a good rolling and agglomeration effect.
4. Drying and screening: The wet granules after granulation contain a certain amount of moisture and are dried. The dried granules are screened through a vibrating screen to separate the granules that do not meet the granules size requirements (too large or too small). Oversized granules can be crushed and returned to the granulator, while undersized granules are returned to the raw material mixing stage as fine powder and re-granulated.
5. Cooling and packaging: The dried granules need to be cooled by cooling equipment to reduce the granules temperature to near room temperature. The cooled granules are screened by screening equipment, and qualified granules enter the packaging process, usually using fully automatic packaging equipment for weighing, packaging and storage.
