Conical Mill, PRM Series
Conical sieve granulating machine for milling of wet or dry granules in pharmaceutical, food, and chemical processes
The conical mill is designed for milling wet materials in pharmaceutical, food, and chemical industries. It features a vertical conical screen that ensures uniform particle distribution and high throughput. Depending on the properties of the material, round-hole, square-hole, or rasp-type screens can be selected. With a large screening area and a high-speed rotating rotor, the PRM conical mill can achieve a processing capacity of up to 1500kg/h.

For powder processing, we also provide a one-stop solution.
Which model is recommended for wet material milling requiring uniform particle size distribution?
Which model is recommended for wet material milling requiring uniform particle size distribution?
The conical mill is an ideal choice. It is designed for pharmaceutical, food, and chemical applications requiring wet granulation or particle size reduction. It delivers uniform particle distribution and excellent flow properties, making it especially effective for milling before or after granulation and drying.
What are the advantages of this mill compared with traditional hammer or high-speed mills?
What are the advantages of this mill compared with traditional hammer or high-speed mills?
Unlike traditional hammer mills, the conical mill operates with a gentle and uniform milling motion that minimizes heat generation and excessive fines. It produces granules with better flowability and narrower size distribution, ideal for heat-sensitive, cohesive, or re-granulated materials.
Can the particle size be adjusted? Is it easy to change components?
Can the particle size be adjusted? Is it easy to change components?
Particle size can be adjusted by using conical screens with different aperture sizes (Ø0.5mm–10mm). The screen can be replaced quickly and without tools, making maintenance simple and efficient for multi-batch or small-lot production.
