Double screw extrusion fertilizer granulation equipment
Double screw extrusion fertilizer granulation equipment is a type of granulation equipment that uses a double screw system to compress and shape fertilizer materials into granules. It is commonly used to produce compound fertilizers, but can also be used for other types of fertilizers.
The double screw extrusion granulator consists of a feeding system, mixing system, extrusion system, cutting system, and a control system. The feeding system delivers the raw materials to the mixing system, where they are thoroughly mixed. The mixed materials are then delivered to the extrusion system, where they are compressed by the double screws and forced through a die plate to form pellets. The pellets are then cut to the desired length by the cutting system and conveyed to the dryer or cooler.
Double screw extrusion granulation equipment has several advantages. It can produce a wide range of compound fertilizers with different nutrient ratios and can handle a variety of materials, including urea, ammonium sulfate, ammonium chloride, and phosphate. The granules produced by this equipment have high strength and are uniform in size and shape.
One disadvantage of double screw extrusion granulation equipment is that it is relatively complex and requires more energy to operate than other types of granulation equipment. It is also more expensive to purchase and maintain
Double screw extrusion granulation equipment is a useful option for large-scale producers looking to produce high-quality compound fertilizers with a high level of control over nutrient ratios and other properties.

Organic Fertilizer Vacuum Dryer
Organic Fertilizer Vacuum Dryer is a type of drying equipment that uses vacuum technology to dry organic fertilizer. In this process, the pressure in the drying chamber is reduced to create a vacuum, which lowers the boiling point of the water in the organic fertilizer, causing the moisture to evaporate more quickly. The moisture is then drawn out of the chamber by a vacuum pump, leaving the organic fertilizer dry and ready for use. Vacuum drying is an efficient and energy-saving way to dry o...
