Lab-scale milling & processing platform

with the SLS - Scalable Lab System

5 powder milling & processing solutions in one platform


Benefits of the Scalable Lab System (SLS)

One platform with five milling, size reduction and processing solutions. 
Smart-Detect technology enables the milling and screening heads to be swapped within seconds with no set up required.

Scalable Lab System (SLS) With All Heads

Lab-scale Milling and processing to production

The SLS Scalable Lab System™ gives the reassurance that particle sizes and distributions achieved in the lab can be directly transferred to the production-scale equipment.  The operating parameters are simply transposed from small-scale to full-scale production.

Key size reduction and material processing technologies are possible from one single platform.  Using the interchangeable heads you can achieve lab-scale conical milling, hammer milling and screening.  The built-in Smart-Detect technology recognizes the head being installed and adjusts the speed range accordingly. This bench-top size milling machine is space-saving as well as cost-effective to own.
