Flat Die Granulator: Designed for Small Factories, Energy-Saving, Durable, and Produces Well-Formed Granules

The flat die granulator is the preferred granulation equipment for small-scale organic fertilizer production lines, family farms, livestock farmers, and small-batch processing. It is a vertical extrusion molding machine, known for its extremely simple structure, low price, energy saving, durability, easy mobility, and quick learning curve, making it the best choice for low-cost investment. The core structure of the flat die granulator consists of a frame, motor, reducer, main shaft, pressure roller, flat die plate, cutter, and discharge hopper. The core component, the flat die plate, is made of high-carbon alloy steel, with evenly distributed circular holes of 3.0-6.0mm in diameter on its surface. The pressure roller is made of wear-resistant alloy material and rotates tightly against the die plate. Under the action of centrifugal force and extrusion force, the material is forcibly extruded from the die holes to form cylindrical granules, which are then cut into uniform lengths by an adjustable-speed cutter. The biggest advantages of the flat die granulator are: the die can be used on both sides, and can be flipped over to continue use after one side wears out, effectively doubling its lifespan; the pressure rollers use an oil-free bearing design, reducing maintenance frequency; the machine is small and lightweight, occupying less than 1.5 square meters, and can be driven by single-phase electricity, making it suitable for small-scale, scattered production. In terms of process adaptability, the machine has relaxed requirements for moisture content, stable molding can be achieved between 25% and 45%, without strict humidity control; it has low requirements for raw material fineness, and can be coarsely crushed after fermentation before feeding into the machine, making it particularly suitable for common raw materials such as chicken manure, pig manure, sheep manure, oilseed cake, and straw powder. The formed pellets are cylindrical strips, with high hardness, not loose, and long-lasting fertilizer effect, making them ideal for orchards, vegetable gardens, and field use. From an operating cost perspective, the flat die pellet mill has extremely low power consumption, inexpensive and easy-to-replace wear parts, and a low total price for the pressure rollers and die, making it easily affordable for ordinary farmers. The disadvantage is that the single-machine output is relatively small, making it unsuitable for large-scale factories. However, for users with limited investment, tight space, and who mainly use the equipment for their own purposes with a small amount of export, it is the most practical, worry-free, and reliable granulation equipment.
