Flat Die Pellet Mill

The choicest Granulator — Columnar Organic Fertilizer Flat Die Pellet Mill

Our company has currently developed flat die granulator, which is one of the main organic fertilizer production equipment. In addition, we design and upgrade it on the basis of the traditional organic fertilizer granulators, overcoming the problems of organic fertilizer like looseness and difficulty in granulation.

  • The machine has simple mechanism and reasonable design, and the granules are easy to dry with low water content.
  • Besides, the granular materials processed by this machine have smooth surface, moderate hardness, and can well maintain the internal nutrients during processing.

We offer a number of models with various types that are appropriate production equipment for small and medium scale fertilizer manufacturing plants. Compared with traditional devices, the flat die pellet mill has great advantages and is considered to be a more efficient way in fertilizer production.

The flat die pelletizer produces columnar pellets without drying or crushing process, which saves a lot of energy. Moreover, it will undoubtedly be the best choice for your organic fertilizer granule production!

Obvious Practical Applications of Flat Die Pellet Mill

Flat die granulator is ideal for coarse fiber granulation such as wood chips, straw, rice husk, cotton stalk, weeds and other kinds of agricultural waste, as well as domestic garbage, waste plastics, and industrial waste. Besides, it is useful for granulation and briquetting of materials with low adhesion rate and difficult to shape, and it can also be applied to low temperature granulation of bio-fertilizer, organic fertilizer and compound fertilizer.

Flat die granulator is mainly used for pellet processing of (biological) organic fertilizer and breeding industry, and it can also be used as livestock feed. Similarly, it can be used as biomass fuel for boilers, gasifiers, gas stations, and biomass power plants.

Production Procedure by Flat Die Pellet Mill

  • The complete granulation line with flat die granulator includes the following equipment: crusher, conveying machine, mixer, flat die granulator, dryer, cooler, screening machine, storage bin and packaging machine.
  • Flat die granulator‘s function is to granulate from organic fertilizer after composting.

1. Differing from the usual method, it eliminates the drying and crushing process of raw materials before granulation, and makes direct batching for processing columnar granules.

           2. After the granules form, you can omit the drying and cooling steps, or choose to carry on the finish machining.

  • The simplest process flow: conveying → compression molding → storing → packing.

Structure Overview

Batching Machine for BB Fertilizer Production

The main structure of flat die pellet mill consists of feeding and discharging system, granulation system, transmission system and control system.

Among them, the flat die and extrusion rollers are this kind granulators’ main components, whose service life and working condition will directly affect the granulating effect, service life and production efficiency of the entire devices.

Such as barrel, spiral auger axis, bearings.

Such as flat die, extrusion rollers, scrapers, cutting knives and the lever for adjusting clearance of molds.

Such as driving gears, driven gears, spindles, box body and bearings.

Such as speed regulator, electric motor, reducer.

How Does A Flat Die Pellet Mill Work?

  • Firstly, the flat die granulator is based on the mechanical circular motion and powered by an electric motor.
  • Under the action of friction, the extrusion rollers rotate themselves and the temperature increases between them and materials, which the high temperature causes the material to melt.
  • When working, the flat die granulator uses extrusion rollers and molds to extrude materials with the shape of strips through the small holes of molds.
  • Finally, while discharging from the outlet, the cutting knives cut these strips to a certain length for finished products.

Why Is The Flat Die Granulator Popular In The Market?

It applies pressing wheels to make machine run smoothly. To a certain extent, this can reduce unnecessary friction between molds and gears, lower energy consumption and production costs. The extrusion rollers and molds are made of alloy to extend the service life of the machine.

The pellets processed by the flat die extrusion granulator have smooth surface, uniform composition and neat shape. The size of granules can be Φ2-Φ10mm, and when ordering the users can choose according to actual production needs.

The flat die granulator can control moisture content of the raw material in the range of 20% to 40%. Due to the low moisture content, the finished products are easy to store, maintain the original shape in the water for a long time, which greatly improve the utilization rate of the materials.

The flat die pelletizer makes full use of the fact that organic particles attaching to each other under certain acting forces, and there is no binder needed for pelletizing.

Flat die granulator applies dry granulation, without investment in the purchase of drying equipment, which can greatly reduce the investment cost in equipment and drying energy consumption.

Flat die pellet mill mainly used for the granules processing of organic fertilizer and aquaculture processing industry. It also can be applied chemical metallurgical materials granulation such as potassium chloride, ammonium sulfate, magnesium sulfate and ferrous sulfate. Furthermore, The flat die granulator is more suitable for powder materials like coal, carbon black, kaolin and stone powder. Meanwhile, it is the ideal granulation equipment for producing biomass energy pellets.

The finished products rate almost above 90%. And the particles processed by the flat die granulator are hard and not easy to break which make transport more conveniently.

The size of the finished granules is related to size of holes on molds used. The same equipment can produce different forms of fertilizer pellets for users to gain more revenue.
