Immersion mill for pail and drum-sized batches
Streamline your production with a versatile solution that efficiently handles the milling, mixing, and dispersion of slurry across multiple batch sizes, optimizing both small-scale and large-scale operations.

Processes and Mixes Slurry for Precision Applications
The HCP Drum Mill by Hockmeyer Equipment Corporation is an engineered-to-order immersion mill designed for handling complex slurry processing needs in the chemical and pharmaceutical industries. Utilizing a circulation milling technology, it ensures efficient mixing and dispersion by rapidly pumping slurry through the media field. This system is ideal for applications ranging from fine chemicals to active pharmaceutical ingredients and specialty paints, employing robust batch and continuous operations. With a 20 Hp motor, the HCP Drum Mill features a unique water-cooled dome for temperature regulation, and an upper auger for consistent material feeding. Its compact design includes an 8-inch diameter basket accommodating up to 2.5 liters of media, enhancing energy efficiency with a variable frequency inverter. Safety features such as a height limit switch and shaft guard provide secure operation, while support legs allow floor mounting for versatile integration. Certified to meet industry standards, this mill supports cleaning and maintenance efforts with an easy-slide rail system for multi-tank servicing, ensuring reliable performance in demanding production environments.
