Feeding System
Equipped with precision feeding hoppers and material conveying devices that ensure uniform, continuous material supply between pressure rollers. Intelligent feeding control automatically adjusts feed rates based on material characteristics, laying a solid foundation for subsequent processes.
Roller Assembly
As the core of the granulation process, this pair of adjustable rotating rollers is manufactured from high-strength alloy materials. By precisely controlling roller gap and pressure parameters, accurate forming of different specification particles can be achieved to meet diverse production requirements.
Crushing System
Professionally designed crushing devices efficiently break extruded sheet materials into small pieces. Unique blade structure and optimized crushing angles ensure uniform material fragmentation, creating ideal conditions for subsequent screening processes.
Screening System
Composed of multi-layer precision screens, the screening system accurately separates qualified particles from substandard products. Innovative vibration screening technology ensures maximum screening efficiency while reducing material clogging incidents.
Control System
An intelligent control system integrating drive units, speed control, and pressure monitoring enables precise regulation of equipment operating status. User-friendly operation interfaces make parameter setting more convenient and production processes more stable and reliable.
Cooling System
Advanced cooling devices provide rapid temperature reduction for materials after granulation, effectively stabilizing internal particle structure. Precise temperature control prevents material quality degradation due to overheating, ensuring excellent performance of final products.
Precision Process Flow
From raw material feeding to finished product output, the six systems of the double roller press granulator form a complete process loop. Raw materials are first evenly distributed through the feeding system, then formed into sheet materials under the powerful pressure of roller assemblies. The crushing system breaks these sheet materials into appropriately sized pieces, while the screening system selects high-quality particles meeting specifications. Throughout the process, the intelligent control system monitors the operating status of each stage in real time, and the cooling system ensures structural stability of final products. This interlocking design philosophy enables the double roller press granulator to consistently produce high-quality pellet products with stable performance.
The Crystallization of Engineering Wisdom
The structural design of the double roller press granulator embodies the essence of modern engineering technology. Each component undergoes meticulous calculation and optimization, achieving near-perfect coordination between different systems. This precision mechanical construction not only ensures efficient equipment operation but also provides users with stable and reliable production assurance. Whether processing fertilizers, chemicals, or food ingredients, this equipment consistently demonstrates with its outstanding performance that superior mechanical design is the fundamental guarantee of quality production.
