Pilot Mill Features


Self-Contained or External Pump
The Pilot Mill comes with a built-in variable flow rate feed pump, ideal for precise control of low to high viscosity products. For larger volumes or specialized applications, an external pump option is available.
Bead Separation Options
The Pilot Mill offers a range of bead sizes, including options for ceramic, glass, steel, and more. Bead separation options can be customized to ensure proper size distribution and efficient milling for various particle sizes, even down to sub-micron levels.
Temperature Control
The Pilot Mill is designed for efficient temperature regulation, with options for water-jacketed chambers. This ensures stable processing conditions and prevents overheating during extended milling sessions. Chillers are available if needed.
Simple Cleaning
Quick-release chamber closures and piping simplify cleaning between runs, minimizing downtime. A suitable solvent can be added during the re-circulation process for easy cleaning of the system.
Custom Controls
The Pilot Mill offers optional PLC controls, including color display and advanced programming for monitoring process variables. This includes data collection and automatic adjustments, providing full control for optimized performance.
Lab Milling and Pilot Mill FAQs
What is lab milling?
Lab milling refers to the process of reducing the particle size of materials in a controlled, small-scale setting. Media milling uses grinding media to achieve this. It is essential for R&D, quality control, determining the best milling conditions, and ensuring that results can be scaled effectively for production.
What is a lab mill?
A lab mill is a small-scale milling device used to reduce the particle size of materials. Media mills use grinding media to accomplish this. Commonly used for small batches, R&D, and gathering data before scaling up to full production.
Why is pre-mixing important for efficient milling?
Pre-mixing breaks down large particles and evenly distributes materials, which improves overall milling efficiency. This ensures more uniform dispersion, reduces wear on the mill, and shortens processing times, leading to consistent product quality. Our lab mixers are a great place to start.
What is the difference between single-pass and recirculation milling?
Single-pass milling involves feeding material through the mill once, while recirculation milling sends the material through multiple times. Recirculation can help achieve finer particle sizes and more uniform dispersion by allowing the material to interact with the grinding media more thoroughly.
What types of materials can be processed in the Pilot Mill?
The Pilot Mill is designed for a wide range of liquid and paste viscosities, including coatings, inks, cosmetics, pharmaceuticals, specialty chemicals, and more.
How does the Pilot Mill scale to production?
Data obtained from the Pilot Mill predicts production outcomes, ensuring a seamless transition from small batches to full-scale manufacturing. When you are ready to scale, find the Production Mill.
What grinding media can be used in the Pilot Mill?
The Pilot Mill accommodates various grinding media, including ceramic, glass, steel, and others, allowing customization based on your specific application. For new or replacement grinding media, visit our grinding media page.
Can the Pilot Mill be customized?
Yes! Chamber sizes, materials of construction, control systems, feed pump options, and more can be tailored to meet your specific requirements.
