Flat Die Pellet Mill

flat die pellet mill

Flat die pellet mill is one important type for organic fertilizer granulation. The capacity is up to 0.08-2.5 tons per hour. Besides, it extrudes the rollers and dies to granulate all kinds of fermented organic materials. What’s more, you can choose corn stalks and other crop stalks, or factory waste as your raw materials. They have a low adhesion rate and are difficult to shape. But the flat die mill can turn them into granules efficiently. Besides, the machine is suitable for low temperature of biological fertilizer, organic fertilizer, and compound fertilizer, etc. We can provide you with various modes for granulating columnar particles of 2-10 mm diameter subsequently. The pellets have high hardness.

Here are more about detailed information about the flat die pellet mill.

Designs of Flat Fie Granulation Machine

What are the special designs for flat die granulator machines? The machine’s structure includes a wheel, two sides of which keep the same rotation speed with the dies. Besides, you can have a better understanding after viewing the three important aspects: shape, roller and dynamic structure.

The flat die granulator adopts a conical shape. This shape makes both ends consistent with the inner and outer rings of the mold plate, and there is no dislocation friction between the wheel and the mold. Therefore, we can reduce the resistance and the kinetic energy loss, but prolongs the service life of the mold. This is one major difference from similar compression molding equipment significantly.

Organic fertilizer flat die pellet mill makes pellets by extruding the rollers and dies. There are more than 20 kinds of dies with different diameters. Thus, the pore size of particle can be divided into: Φ2, Φ2.5, Φ3.5, Φ4, Φ5, Φ6, Φ7, Φ8, etc. Finally, the extruded pellets’ surface is smooth and clean, and the hardness is moderate.

It adopts the screw center pressure regulating mechanism. Its pressure roller adopts a large body and a wide groove, which is pressure-resistant and wear-resistant. The pressure roller adopts multiple uniform distribution, which ensures stable operation. They will also help increase the pressing area and improve the production efficiency. The mold gap can adjuste according to the size. Therefore, it is suitable for different materials’ granulation, and the pressing effect can also be guaranteed.

Advantages of these designs

These designs make flat die granulator making machine work efficiently in the production line. It can manufacture cylindrical organic fertilizers independently. It can also work with an organic fertilizer polishing machine. They can make one-time-shaping come true. Besides, the uniform setting of the pressing rollers in the machine ensure its smooth operation. Therefore, you can granulate efficiently and get higher fertilizer particles productivity.

After you have a basic understanding of the important designs of the flat die pellet making machine, it’s time for you to know how it works and functions.

Flat Die Pellet Mill Machine’s Working Conditions

It uses dry granulation instead of wet granulation.

Flat die granulator equipment extrudes pellets from the die hole under the extrusion of the pressure roller. You can add various additives into the pellets’ processing. The materials are dry to put in and the dry products get out from the outlet. They are convenient for sealed storage later. The natural temperature is up to 70-80 degrees, which can kill pathogenic microorganisms and parasites easily, and ensure organic matter content. Similarly, the low moisture pellets are easy for storage. They can keep for a long time in the water, which improves the materials’ utilization greatly.

Every part’s normal running makes flat die pellet mill machines work steadily.

In the process of flat die pellet press machine, we can divide it into three parts: break and separating part, transmission connection part and head working part.

(1)Break and separate part: After you put into the raw materials, they are pressed by the rollers. Then they’re going into the breaking device. You can separate the qualified pellets and the return material through this equipment.

(2)Transmission connection part: When the transmission connection parts are working, the electric motor will drive the pulley, V-belt, and reducer to rotate and granulate the fertilizer pellets. In addition, there is a transmission chain composed of sprocket and chain, which is the main motivation for driving the crushing and separate part. We also use the mutual work of the nylon pin coupling to drive the transmission reducer and the head working part.

(3)Head working part: Then for the head working part, we use a pair of open wheels to ensure that the pair of rollers are synchronized. In addition, both sides of the active and passive shafts are composed of specific bearings and bearing frames, which installs on the frame.

Four Tips to Handle Flat Die Fertilizer Granulator Easily

To operate a flat die granulation machine easily, our company will give you four tips from the beginning to the end to the pellets’ processing.

    1. After adding hyperbolic gear oil in the gearbox, the machinecan startwork.
    1. Install the granulator stably, adjust the belt’s tightness, and make sure whether the steering is normal, or whether the screws in each part are loose or not. If themachine is in a no-load stateand starts normally, it can be put into use.
    1. If there are more refined fibers during material processing, add5% of waterapproximately. The water will be lost during the extrusion proces
    1. Loosen the screwsafter processingand keep the rollers in a free state. Remove the upper and lower bins after the shutdown, especially the remaining materials under the spinner. These jobs are to avoid damage to the bearings.

Different Models of Flat Die Pellet Mills for Sale

There are mainly three flat die pellet equipment models in our company, SXPM-400, SXPM-500, and SXPM-600. They can make 2-10 mm pellets according to your needs. The granulation rate is up to 95%.
