A double roller press granulator is a molding equipment that transforms powdered materials into regular granules based on the principle of dry extrusion. Also known as a double roller granulator, it is widely used in various industrial fields due to its high efficiency, energy saving, and convenient operation, becoming one of the core equipment in modern particle processing. It eliminates the need for complex drying and cooling processes, relying on mechanical high pressure to achieve material molding, and is suitable for the granulation needs of various powdered raw materials.
Its working principle is simple and efficient. The core structure consists of two parallel, counter-rotating extrusion rollers and auxiliary systems such as feeding, transmission, and lubrication. Powdered material is evenly fed between the two rollers by the feeding system. Under the high pressure driven by hydraulics, the intermolecular forces of the material are enhanced, and the material is forcibly squeezed into the grooves of the roller surface to form block-shaped granules. After crushing and screening, unqualified powder is returned for reprocessing, and qualified granules are formed. The entire process does not require the addition of binders or extra water, which maintains product purity and simplifies the process.
The core advantages of this equipment are prominent: firstly, it is energy-saving and environmentally friendly. The dry process eliminates the drying step, significantly reducing energy consumption, and there are no wastewater or exhaust gas emissions, aligning with green production; secondly, it produces high-quality granules. Adjusting the roller gap and pressure can precisely control the particle size and hardness, with a granulation rate of over 90%; thirdly, it has strong adaptability and can process various materials such as compound fertilizers and mineral powders, adapting to different scenarios; fourthly, it is easy to maintain. It has a compact structure, occupies a small area, and the rollers are wear-resistant, requiring only regular lubrication and inspection for stable operation.
In practical applications, its role is significant: in the fertilizer industry, it can be used in various compound fertilizer production lines, improving storage and transportation convenience; in the environmental protection field, it can transform industrial waste such as fly ash and sludge into usable granules, achieving resource utilization; it is also widely used in chemical and building materials fields, processing catalysts, refractory materials, etc., improving the production environment and material utilization rate.
As an efficient and environmentally friendly particle molding equipment, the double roller press granulator, with its unique advantages, simplifies processes and reduces costs, contributing to the green and efficient development of various industries, and becoming an indispensable important equipment in modern industry.
