The granulating organic fertilizer equipment commonly used in the production of organic fertilizers includes disc granulator machine, npk fertilizer granulator, drum granulation, wet granulator, roller extrusion granulator, flat die granulator, ring granulator, etc. The fertilizer granulator machine price varies. Let’s take a look at the flat die granulator.
Flat die granulator is suitable for granulation of rough fermented organic fertilizer. Mainly suitable for coarse fiber granulation, such as: wood chips, rice husks, cotton stalks, cottonseed husks, weeds and other crop straws, household garbage, waste plastics and factory wastes, granulation of materials with low adhesion rate and difficult to form , briquetting, bar making, and also suitable for low-temperature granulation of biological bacterial fertilizer, organic fertilizer, compound fertilizer, etc.
The advantages of the flat die granulator are: wide adaptability of raw materials, especially for organic substances, wide requirements on raw material density and raw material moisture, and raw materials do not need to be dried. The diameter of the pressing roller is large, the template can be used in both positive and negative directions, the material is evenly distributed in the compression chamber, the granulation is stable, the particle forming rate is high, the appearance of the finished particles is uniform and not easy to break, the production capacity: 1.0 ~ 4.0 tons / hour; % or more, less material is returned; power: 22 to 90 kilowatts. No water is added in the whole granulation and forming process, which saves the cost of subsequent granule drying. The requirements for the fineness of raw materials are not high, and the granulated raw materials (after composting) generally do not need to be finely pulverized, and small stones can be directly crushed.
The disadvantages of the flat die granulator are: the flat die granulation machine consumes a lot of energy, and the extrusion strength is large. When iron and steel waste is mixed into the organic fertilizer raw material, it is very easy to damage the granulation template and sometimes block the granulation template hole. Additional equipment care and replacement of consumables are required. At the end of each shift, it is best to add blocking materials to granulate to prepare for the next shift of workers.
