The choicest Granulator — Columnar Organic Fertilizer Flat Die Pellet Mill

Our company has currently developed granulator s ravnom matricom, which is one of the main organic fertilizer production equipment. Osim toga, 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.
Osim toga, 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. Štoviše, it will undoubtedly be the best choice for your organic fertilizer granule production!

Obvious Practical Applications of Flat Die Pellet Mill

Ravni granulator is ideal for coarse fiber granulation such as wood chips, slama, rižina ljuska, stabljika pamuka, korova i drugih vrsta poljoprivrednog otpada, kao i kućno smeće, otpadna plastika, i industrijski otpad. Osim toga, 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.

Ravni 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 granulator s ravnom matricom includes the following equipment: crusher, conveying machine, mixer, granulator s ravnom matricom, dryer, cooler, screening machine, storage bin and packaging machine.
Ravni 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.

Note:

Raw materials like livestock manure with high water content need to be dried before granulation to reduce the moisture.
Composted materials generally do not need to be finely crushed, while wood chips with suitable moisture can be directly granulated.
To avoid damage to the roller surface, raw materials with large volume or density must be crushed in advance.

Structure Overview

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

Među njima, the flat die i 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.

Feeding System

Such as barrel, spiral auger axis, bearings.

Granulation system

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

Transmission system

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

Control system

Such as speed regulator, električni motor, reducer.

How Does A Flat Die Pellet Mill Work?

Prvo, the flat die granulator is based on the mechanical circular motion and powered by an electric motor.
Pod djelovanjem trenja, the extrusion rollers rotate themselves and the temperature increases between them and materials, što visoka temperatura uzrokuje topljenje materijala.
Prilikom rada, the flat die granulator uses extrusion rollers and molds to extrude materials with the shape of strips through the small holes of molds.
Konačno, tijekom pražnjenja iz utičnice, the cutting knives cut these strips to a certain length for finished products.

Why Is The Flat Die Granulator Popular In The Market?

Reasonable Structure of Flat Die Pellet Mill

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.

Beautiful Appearance of Finished Products

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.

Keep Poor Materials Moisture Content

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.

No Binder Required in Pelletizing

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.

Low Investment Cost

Ravni 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.

Wide Range of Use

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, amonijev sulfat, magnesium sulfate i ferrous sulfate. Nadalje, The flat die granulator is more suitable for powder materials like coal, carbon black, kaolin and stone powder. U međuvremenu, it is the ideal granulation equipment for producing biomass energy pellets.

High Finished Products Rate

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.

High Applicability of Particles Size

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.
