The introduction of double roller press granulator

The DZJ series double roller press granulator is an improved pressing granulator equipment based on years production experience and feedback from customers in the production practice. The double roller press granulator is widely applied to Fertilizer Production ,Feed Production and Chemical Industry for granulating powder material.

Double roller press granulator is a widely used equipment in fertilizer manufacturing process. It presses powdered or granular materials into dense flakes by applying high pressure to the materials, and then forms uniform granules through crushing machine and fertilizer granulator machine processes.

The working principle of this double roller press granulator is as follows

The raw material enters the roller gap of the double roller press granulator through the feeding device. After the material enters the roller granulator, it is squeezed under high pressure under the action of the relative rotation of the two rollers. The high pressure makes the particles in the material closely contact and bond together to form a dense flake material. The crushing device crushes large pieces of flake material into smaller particles. The particles after preliminary crushing enter the shaping device and are further homogenized through rolling, screening and other processes. The shaping device can adjust the size and shape of the particles as needed to meet specific product requirements. The final formed particles are discharged through the discharge port and enter the next process or are directly packaged.

Here are some common materials that can be used in a double roller press granulator for producing different types of fertilizer granulator.

The common materials for nitrogen fertilizers include urea and ammonium nitrate.

The common materials for phosphate fertilizers include MAP and DAP.

The common materials for potassium fertilizers include potassium chloride (MOP) and potassium sulfate (SOP).

The main type of compound fertilizer is NPK fertilizer, which combines NPK elements and can be produced in NPK fertilizer production line.

Organic fertilizers can be processed into granules using a double roller press granulator, where fermented organic materials such as animal manure and crop straw are compacted into pellets

By using a double roll press granulator, these different types of fertilizer raw materials can be effectively converted into uniform particles, improving the use efficiency and application convenience of fertilizers, and meeting the nutritional needs of different crops.

The advantages of double roller press granulator

The double roll press granulator,adopts to No-Drying technology,granulating at normal temperature ,forming one time ,reasonable structure design,stable and reliable operation ,convenient operation and maintenance,with less investment ,quick effect ,considerable economic benefit characteristics and so on.

In addition, the transmission part of DZJ-ǁ Double Roller Press Granulator adopts double input powder transfer mode to improve the input powder ratio and ensure the lubrication and sealing performance of the transmission gear.
