VIBRO-ENERGY^®MILL

for Ultra-fine Grinding, Micronizing and Blending

Vibro-Energy® Mills
Only the Boulton design of Vibro-Energy® Mill has the vibratory generator mounted at the centre of gravity of the mill chamber with the coil springs mounted around the periphery of the chamber.

This design produces maximum grinding efficiency compared to our old, low amplitude, original design with the vibratory generator and springs mounted below the chamber, although this design is still used as it is best suited for our polishing and blending mills where a more gentle action is required.

Boulton Vibro-Energy® Mills offer versatile, low cost, controlled particle size reduction with minimal wear and product contamination. No other type of mill has so few mechanical moving parts. Power consumption is low as there are no rotating impellors or drums.

The mills utilize inert high density sintered ceramic or carbide grinding media for iron-free grinding. The media is cylindrical or ball shape and is subjected to a high frequency, high amplitude vibration producing a vibrating and tumbling vortex action within the annular shaped grinding chamber. The process material fills the void spaces within the media mass.

In conjunction with cylindrical shaped grinding media the close packed mass preferentially reduces larger particles due to the media line and plane contact surfaces, producing milled materials with a narrow particle size band distribution. All mills are adjustable for low amplitude operation if required.
Mill contact parts are either cast polyurethane at hardness 85-90 Shore “A”, polyethylene, vulcanised rubber or steel.
All mills are primarily designed for wet fine grinding in the particle size range
5 mm to sub micron, either batch, continuous - open or closed circuit operation.

Sizes range from 1 litre to 1500 litres working volume.

Dry batch or continuous mills are available for specialised applications

Dry batch mills for special pharmaceutical blending and milling processes
Suitable for vacuum or pressurized operation with gas or liquid purge facility.

Pharmaceutical Mill

Operating frequency is 16 - 19 cycles per second. Maximum vertical amplitude of vibration is 9 mm.

Internal surfaces of the chamber are crevice-free, lined with FDA approved hard polyurethane.

The mill is suitable for vacuum or pressurised operation, incorporating gas or liquid purge facility. Tri-clamp fittings and silicone rubber seals are standard.

Data acquisition instrumentation such as amplitude of vibration transducers, temperature and humidity probes are also available.

Vibro-Energy Mixers/Blenders operate at a more gentle, higher frequency than the grinding mills, producing a fast vibrating and tumbling vortex action within the annular shaped chamber for the mixing and blending of dry materials.

Inherently safe in operation

No guarding required

No ferrous contamination

Minimum space requirements

Easy to install

Low power consumption

As there are no rotating parts within the mixing chamber, the machine is completely safe in operation, is easy to clean, has no rotary shaft seals and offers a lower cost alternative to traditional screw, paddle, blade and ribbon type mixers. Sizes range from 25 litres to maximum 1100 litres working capacity.
