Product Description

The double roller granulator (also known as the double roller extrusion granulator) is a device that forces powdered materials to be compressed into granules through the mechanical pressure of rollers. It is widely used in the fields of fertilizers, chemicals, organic fertilizers, etc. The following is a systematic analysis based on market data and industry practices in 2025, covering aspects such as core features, technical parameters, applicable scenarios, and procurement suggestions.

Youdaoplaceholder0 I. Core features and working principle ‌
Youdaoplaceholder0 Working principle ‌ : The equipment uses hydraulic or mechanical drive to squeeze the roller. Through the flat die and the roller thread clearance adjustment device, wear is reduced and the service life is increased by about 30%. The low-temperature extrusion process (usually ≤60℃) ensures a high granulation rate and no nutrient decomposition.
Youdaoplaceholder0 Key advantage ‌ :
The granulation rate is as high as over 90%, and the compressive strength of the particles is greater than 8 Newtons, making it suitable for the demand of high-hardness particles
Energy-saving and highly efficient: The dry granulation process does not require a drying step, and its energy consumption is 50% lower than that of the wet method. It is suitable for heat-sensitive materials (such as nitrogen-containing compound fertilizers).
Low cost: Short payback period for equipment investment, simple operation and maintenance, suitable for medium and small-scale production lines.
Youdaoplaceholder0 2. Applicable scenarios and capacity fit ‌
It is applicable to the granulation of powdered materials such as NPK compound fertilizers, organic bio-fertilizers, fine chemical raw materials (such as antioxidants, rubber additives), and metallurgical auxiliary materials. Specific scenarios include:

Youdaoplaceholder0 Small and medium-scale production ‌ : Output 1-5 tons per hour, annual production capacity 10,000-50,000 tons, especially suitable for family farms or regional fertilizer processing enterprises 110.
Youdaoplaceholder0 Special material handling ‌ : Dry powder materials with moisture content < 5% (such as compound fertilizer powder) are directly formed by extrusion, avoiding the drying step of the wet process
