Small Batch, Precise, Economical, and Versatile
CB Mills 
Laboratory Vertical Grinding Mills are designed for research, formulation, and small-lot production batches. Compact, economical, and reliable, these mills help manufacturers determine critical process endpoints such as color, particle size, and probable production rates before scaling up to full production.
- Built for flexibility, our lab mills can be operated on a standard utility drill press with a ½ HP drive at 2,400 RPM spindle speed. Alternatively, we offer a turnkey Power Stand ensuring a hassle-free setup.
- All models feature stainless steel contact parts for durability and contamination control, with agitators available in either cast alloy or nylon to match your formulation needs.
Key Features & Benefits
- Economical Small-Batch Milling – Ideal for producing test dispersions and short-run applications.
- Explosion-Proof Reliability – Motor design includes an explosion-proof build and 2,400 RPM spindle speed.
- Customizable Agitators – Choose cast alloy or nylon for different grinding requirements.
- Durable Stainless-Steel Construction – All contact parts are stainless steel for long life and product integrity.
- Optional Power Stand – L-3-J and L-5-P model available with integrated stand for lab convenience.
Available Models
- L-1 (1 Liter, Water-Jacketed) – Designed for 300 ml samples with temperature control. Perfect for testing color, particle size, and production potential.
- L-2 (1 Liter, Top-Feed Continuous) – Includes a 45-mesh screen and no water jacket; ideal for quick bracketing of vehicle/pigment loadings.
- L-3 (2 Liter, Top-Feed Continuous) – Same design as the L-2 but with double capacity for higher throughput.
- L-3-J (2 Liter, Water-Jacketed) – Continuous-feed grinding mill with temperature control, 45-mesh screen, and expanded capacity. Ideal for short-run applications where thermal management is essential.
- L-5-P (5 Liter, Water-Jacketed) – Continuous-feed grinding mill with temperature control and 45-mesh screen. Ideal for scaling up from lab to pilot production while maintaining precise thermal management and dispersion quality.
The Small Batch Laboratory Mills give R&D teams the ability to test, refine, and optimize formulations before full-scale production, by saving time, reducing costs, and ensuring quality.
