Disc granulator MKGD-5000 - 5000 kgh for organic and NPK fertilizers
Details:
MKGD-5000 Disc Granulator with 5000 kg/h Capacity for Organic and NPK Fertilizers
The MKGD-5000 disc granulator from Meelko is a high-capacity industrial machine designed for the mass production of spherical granules for the fertilizer industry. With a processing capacity of 5000 kilograms per hour and a disc diameter of 3200 millimeters, this granulator represents the most powerful solution in the Meelko product line for fertilizer plants requiring high production volumes with consistent quality in every manufactured batch.
Superior Capacity and Large Diameter Disc
The 3200 millimeter diameter disc of the MKGD-5000 is the largest available in the Meelko granulator line. This extensive working surface allows simultaneous processing of large quantities of powdered material, maximizing the efficiency of the granulation process throughout each production run. The relationship between disc diameter and production capacity has been optimized through years of experience in designing equipment for the fertilizer industry, ensuring that every square meter of surface is utilized to its full potential.
The 37 kilowatt electric motor provides the necessary torque to maintain constant rotation of the large diameter disc even when operating at full capacity with high-density materials. The high-efficiency helical gear transmission minimizes power losses between the motor and the disc, ensuring that most of the energy consumed translates into useful granulation work. The energy consumption per ton of product is remarkably low considering the production scale of this equipment model.
Agglomeration Granulation Process
The granulation process in the MKGD-5000 is based on the rolling agglomeration principle on the inclined rotating disc surface. The powdered material is continuously fed onto the disc surface while a binding solution is sprayed to promote particle adhesion and nuclei formation. As the granule nuclei roll across the inclined surface, they grow by incorporating additional particles until reaching the desired size specification. Formed granules are discharged continuously over the disc edge into the collection system below.
The disc inclination angle, typically adjustable between 40 and 55 degrees, controls the material residence time and the final granule size produced. A steeper inclination produces smaller granules with shorter residence time, while a shallower inclination allows the formation of larger granules with more time for growth. The disc rotation speed also influences the density and sphericity of the final product. These parameters are easily adjusted during operation to obtain the exact characteristics required by each product specification.
Applications in Organic and NPK Fertilizers
The MKGD-5000 is the preferred choice for large-scale organic fertilizer production plants processing compost, dehydrated manure, vermicompost, biochar, and other sources of organic matter for agricultural use. Granulation transforms these materials into uniform spherical granules that are much easier to store, transport, and mechanically apply in the field compared to the original powder or irregular form that is difficult to handle and spread evenly.
In the production of compound NPK fertilizers, the granulator allows combining nitrogen, phosphorus, potassium, and micronutrient sources in a single homogeneous granule for balanced crop nutrition. Each granule contains the exact nutrient proportion specified in the formula, ensuring balanced crop nutrition at every application point across the field. The equipment is also used in the production of granulated limestone amendments, agricultural gypsum, slow-release fertilizers, and specialty products for precision agriculture applications.
Quality Control and Uniformity
The quality of granules produced can be controlled through multiple operating parameters that the operator adjusts according to product specifications and market requirements. The quantity and distribution of binding liquid, controlled through precision spray nozzles positioned above the disc, directly affects the mechanical strength and porosity of the finished granule. A size classification system at the granulator outlet separates in-specification product from material requiring reprocessing, guaranteeing uniformity in the final commercial product.
The equipment produces granules with diameters varying between 2 and 8 millimeters depending on parameter configuration and material characteristics. The particle size distribution can be adjusted to meet commercial standards for each target market segment. The mechanical strength of the granules is sufficient to withstand stacking in bags and mechanized handling without disintegrating, while the soil dissolution rate can be controlled through appropriate binder selection and process parameter optimization.
Maintenance and Technical Support
Preventive maintenance of the MKGD-5000 includes periodic disc lining inspection, main shaft bearing verification, transmission system lubrication, and spray system review for proper operation. The modular design facilitates access to components requiring regular maintenance attention. Meelko offers specialized technical support for commissioning, parameter optimization, and comprehensive operator training programs.
Meelko maintains an inventory of original spare parts and provides remote or on-site technical assistance according to customer needs and production urgency. The company experience in manufacturing equipment for the fertilizer industry guarantees effective solutions for any technical requirement. The engineering team can advise on optimal product formulation, binder selection, and complete granulated fertilizer production line configuration for maximum efficiency and product quality.
