LDH-15 Precision Coulter Mixing Machine 82.5kW Industrial Powder Mixer 6000-9000kg Per Batch

The LDH-15 coulter mixing machine is the largest model in the LDH series, a heavy industrial powder blender engineered for mega-scale dry blending operations that need efficient mixing and uniform quality in the biggest batch sizes available. The horizontal cylindrical chamber carries high-speed coulter (ploughshare) blades that rotate close to the inner wall, lifting material into a continuous fluidized state. This three-dimensional motion combines convective turnover with intense shear, rapidly dispersing powders, granules and trace additives throughout the charge. Rated for 6000-9000 kg per batch with an installed power of 82.5 kW and a total equipment weight of 9200 kg, the LDH-15 defines the top end of high-capacity dry blending in chemical, pharmaceutical, food, feed and building material industries.

• LDH Series Coulter Mixing Technology: High-speed coulter blades create a fluidized bed with strong convective and shear action, delivering short cycles and complete dispersion of dry solids.
• Ultimate Industrial Throughput: The 6000-9000 kg working range is the largest in the LDH series, minimizing the number of batches needed per shift.
• Uniform Quality Batch After Batch: Repeatable three-dimensional particle movement keeps composition consistent from the first charge to the last.
• Powerful 82.5 kW Drive: The high-torque drive fluidizes dense, cohesive and high-bulk-density powders reliably at maximum load.
• Massive Heavy-Duty Construction: At 9200 kg the reinforced frame and chamber provide exceptional stability and low-vibration operation under continuous industrial duty.
• Full-Volume Discharge: The bottom outlet empties the chamber completely, reducing retention and shortening the cycle between batches.
• Service-Friendly Design: Inspection openings and an accessible blade assembly simplify routine checks and wear-part replacement.

Operating the LDH-15 coulter mixing machine follows the same dependable routine proven across LDH series installations. Load the dry components into the chamber, start the blades, and let the fluidized motion blend the charge; for most free-flowing powder recipes the cycle is short, and our engineers will recommend a mixing time based on your material density and particle size. Keep each charge within the rated 6000-9000 kg window, because underloading reduces mixing efficiency while overloading restricts fluidization and extends the cycle. Position the machine on a properly engineered, level foundation with clearance below the discharge outlet, and have the 82.5 kW supply connected by a qualified electrician following the wiring diagram supplied with the unit. Between batches, wipe down the chamber interior and discharge area to prevent carry-over; for hygienic applications the accessible design supports more thorough cleaning. These practices come from real operating experience with similar machines and help plants achieve consistent quality from the first week of service.

The LDH-15 coulter mixing machine handles dry blending duties across chemical, pharmaceutical, food, feed and building material industries. Typical tasks include premixing active ingredients with excipients, homogenizing pigment and additive masterbatches, blending feed premixes and mineral supplements, mixing fertilizer and pesticide granules, and preparing detergent or seasoning powder formulations. Its very large batch size suits plants running continuous daily production of a limited number of formulations, while the low-residue design still allows quick changeover when recipes change. Materials with different particle size and bulk density are processed while maintaining uniform quality throughout the batch.

Every LDH-15 coulter mixing machine is factory test-run before shipment to verify mixing performance, power consumption and safety interlocks, and the results are recorded in the quality inspection certificate delivered with the machine. The unit is packed in an export-grade wooden case with protective wrapping for long-distance sea or air freight. Standard documentation includes the operation manual, wiring diagram and inspection certificate. Our after-sales team provides online technical guidance for installation, commissioning and troubleshooting, and spare wear parts are kept in stock for quick replacement. We provide honest, verifiable information: if your material needs special handling or a different configuration, we will tell you before you order rather than after.
