Disc granulator MKGD-3000 - 3000 kgh for organic and NPK fertilizers
Details:
MKGD-3000 Disc Granulator with 3000 kg/h Capacity for Organic and NPK Fertilizers
The MKGD-3000 disc granulator manufactured by Meelko is a high-performance industrial machine designed for the mass production of spherical granules from powdered materials. With a processing capacity of 3000 kilograms per hour, this equipment is ideal for fertilizer plants that need to transform raw material mixtures into uniform granules with optimal physical properties for storage, transportation, and field application in modern agricultural operations worldwide.
Disc Granulator Operating Principle
The disc granulator operates through a rolling agglomeration principle on an inclined rotating disc surface. The powdered material is fed onto the disc surface that rotates continuously while a binding solution is applied through spray nozzles positioned above the working area. The powder particles begin adhering to each other forming nuclei that grow progressively as they roll across the disc surface. The inclination angle and rotation speed of the disc determine the final granule size and the material residence time within the equipment.
The 2800 millimeter diameter disc provides an extensive working surface that allows processing large volumes of material simultaneously during continuous production runs. The lateral walls of the disc are designed with an optimal height that retains the material for the time necessary to complete granule formation before discharge. An adjustable scraper keeps the disc surface clean and prevents accumulation of adhered material that could affect the quality and uniformity of the final product during extended operation periods.
Technical Specifications and Motor System
The 22 kilowatt electric motor driving the MKGD-3000 has been sized to provide the necessary torque for maintaining constant disc rotation even when operating at full load capacity with high-density materials. The helical gear transmission system ensures smooth and efficient power transfer with minimal energy losses throughout the drive train. The disc rotation speed can be adjusted to optimize the granulation process according to the specific characteristics of the material being processed in each production campaign.
The granulator structure is built with high-strength structural steel welded with precision that provides the rigidity necessary to withstand the dynamic loads generated during continuous operation. The equipment base includes reinforced anchor points for secure attachment to the plant floor surface. The main disc shaft is mounted on high-capacity bearings with hermetic seals that protect against dust and moisture ingress, ensuring a long service life for critical rotation components under demanding industrial conditions.
Applications in the Fertilizer Industry
The MKGD-3000 is widely used in the production of organic fertilizers from compost, processed manure, vermicompost, and other organic materials available from agricultural and livestock operations. The granulation process significantly improves the physical properties of the fertilizer, facilitating precise dosing, mechanized field application, and prolonged storage without caking problems. The organic granules produced present a uniform spherical shape with good mechanical resistance that minimizes dust generation during handling and transportation.
In the production of compound NPK fertilizers, the granulator allows simultaneous mixing and granulation of nitrogen, phosphorus, and potassium sources along with essential micronutrients in a single processing step. The homogeneity of each granule ensures that the plant receives balanced nutrition at every application point across the field. The equipment also finds application in the production of granulated limestone amendments, controlled-release fertilizers, and other specialized products for modern precision agriculture practices.
Quality Control and Product Uniformity
The quality of granules produced by the MKGD-3000 can be controlled through the adjustment of multiple operating parameters during the production process. The disc inclination angle, typically between 40 and 55 degrees, determines the material residence time and final granule size produced. The rotation speed influences the density and sphericity of the product during formation. The quantity and distribution of the binding liquid affect the mechanical resistance and porosity of the finished granule for end-use performance.
The equipment allows production of granules with diameters varying between 2 and 8 millimeters depending on the configuration of operating parameters and the type of material being processed. The particle size distribution of the final product can be optimized to meet the commercial specifications required by each target market. A size classification system located at the granulator outlet separates the finished product from off-specification material that is recirculated to the process for reprocessing to minimize waste.
Maintenance and Meelko Technical Support
The preventive maintenance program recommended by Meelko includes periodic inspection of the disc lining for wear, verification of main shaft bearing condition, lubrication of critical points in the transmission system, and review of the binding liquid spray system for proper operation. The equipment design facilitates access to all components requiring regular maintenance, minimizing downtime periods and maximizing the operational availability of the machine throughout the production season.
Meelko offers specialized technical support that includes advisory for equipment commissioning, process parameter optimization for each product type, and comprehensive operator training programs. The company maintains a permanent inventory of original spare parts and can provide remote or on-site assistance according to customer needs and production urgency. The accumulated experience of Meelko in manufacturing equipment for the fertilizer industry guarantees effective solutions for any technical requirement related to the MKGD-3000 granulator system.
