Also known in the industry as a pan granulator or disc granulator, this machine is a mainstream wet granulation device used in the processing of organic fertilizers, compound fertilizers, and bio-bacterial fertilizers. It utilizes the centrifugal force generated by the rotating disc, along with the material's own weight and friction, to agglomerate powdered materials into granules. It is widely used in small- and medium-sized fertilizer processing plants, facilities for the resource utilization of livestock and poultry manure, and production lines for granular agricultural fertilizers.
The Huaqiang Heavy Industry standardized disc granulator consists of four main modules, all fabricated from heavy-duty industrial steel; individual components are detachable, facilitating easy operation, maintenance, and repair.
Frame and Base Assembly: Constructed from integrally welded, heavy-gauge channel steel with a weighted base, allowing for stable placement without the need for embedded anchor bolts—ideal for flexible factory layout adjustments.
Tilt Angle Adjustment Mechanism: Utilizes a combination of a lead screw and angle shims, allowing for stepless adjustment of the disc tilt angle between 35°and 60° to directly control granule size.
Drive and Power System: Features a motor paired with a flexible belt-drive reducer; the main gear undergoes high-frequency quenching for wear resistance, cushioning startup impact and minimizing gear wear.
Granulation Disc Body: Features a seamless, curved disc face reinforced with radial steel plates at the bottom to prevent deformation, and is lined with anti-corrosive, non-stick fiberglass (FRP); equipped with three sets of non-powered scrapers that simultaneously clear material buildup from the disc bottom and walls.
The disc granulator is highly adaptable to various materials and can process a wide range of non-sticky or lightweight, fine-powdered substances. Specific examples include:
Organic fertilizer raw materials: Composted livestock and poultry manure (chicken, pig, cattle, etc.), humic acid, straw powder, spent mushroom substrate, sludge, peat, etc.
Compound/mixed fertilizer raw materials: NPK raw materials, urea, ammonium chloride, ammonium sulfate, ammonium bicarbonate, etc.
Mineral powders: Bentonite, kaolin, mineral powder, coal dust, cement, iron ore pellets, etc.
Others: Animal feed, chemical raw materials, pharmaceutical raw materials, food ingredients, etc.

Compared to rotary drum granulators and extrusion granulators, the disc granulator offers the following distinct advantages:
Disc granulator features a simple structure and low manufacturing costs; investment costs can be reduced by over 40% compared to large-scale extrusion granulation equipment, and total investment savings of 30% can be achieved relative to other compound fertilizer production processes.
High granulation rate and excellent granule quality: The granulation rate reaches 93%-95%; the finished granules are round, uniform, high-strength, and consistent in appearance.
The unit features a compact layout with a small footprint, eliminating the need for complex civil engineering foundations. Installation and commissioning are straightforward, and routine maintenance involves only periodic checks of disc liner wear, residue removal, and lubrication.
The flexible belt drive ensures smooth startup and absorbs impact forces; the thickened, weighted base design allows for stable operation without the need for anchor bolts.
Both the disc inclination angle (adjustable between 30°and 60°) and the rotation speed can be adjusted, allowing for precise control of granule size.
It can process a wide variety of materials and is highly adaptable to formula changes.
The disc granulator typically operates as part of a completefertilizer production line; common auxiliary equipment includes:

Pre-processing equipment: fermentation compost turner, crusher, mixer, automatic batching system
Conveying equipment: belt conveyor
Granulation core: disc granulator (equipped with a spraying device)
Post-processing equipment: dryer, cooler, screening machine
Packaging equipment: automatic packaging machine
Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd. is a specialized manufacturer of organic fertilizer equipment with extensive experience in the R&D and production of granulation machinery. The Huaqiang disc granulator offers the following key advantages:
The disc body is formed from a single piece of thickened, high-quality steel plate and reinforced at the bottom with multiple radial steel ribs, ensuring exceptional structural rigidity and load-bearing capacity. The disc surface features a wear-resistant, anti-corrosive lining (high-strength fiberglass) that significantly reduces material abrasion and enhances corrosion resistance. Its thickened, weighted, and sturdy base design ensures stable operation without the need for anchor bolts.
The design features a seamless, arc-shaped disc corner, eliminating production "dead zones." The granulation rate consistently reaches 93%-95% or higher. The resulting pellets are round, uniform, and strong, with an adjustable output size ranging from 2mm to 6mm.
As the original manufacturer, Huaqiang Heavy Industry eliminates intermediary markups. We offer custom specifications and dimensions, supply complete organic fertilizer production line equipment, and provide one-stop services including site surveys, production line layout, equipment installation and commissioning, technical training, and after-sales support.
