The VibroKinetic Energy (VKE) Mill is designed to fill the need for a fine to ultrafine grinding mill which is both low cost and economical to operate.  Optional features include air classification while dry grinding, which greatly improves the efficiency of the mill.  Wet grinding with hydrocyclone recycle for accurate sizing, and use of vibratory table for concentration of ore values is also available.

The VKE mill is the most efficient fine grinding mill available. Extremely fast and very energy efficient, the VKE mill is very versatile and can be operated either wet or dry. The air injection system provided with the dry mills can be used to elutriate the material during the grind to pull sized fines out of the mill and allow the mill to grind only oversize material.

The VKE mill is available in four sizes:

Model 624, with a 6" x 24" tube, is a 1/2 hp laboratory size mill of table top dimensions.  It is ideal for small scale continuous or batch test grinds. Learn More

Model 1040 is a 2 1/2 hp pilot mill with a capacity to produce around 300 lbs. per hour of fine material from 1/4" feed.  This size is ideal for pilot plants, small mining operations, pigments and cosmetic applications.  It is of modular design and can be used in multiples, if desired. Learn More

Model 2080 is the standard production mill, although for very heavy materials a shorter 60" tube is recommended.  Both carry a 9 hp motor and the standard unit will produce one ton per hour of fine material from hard 1/4" feed material. Learn More

Model 3080 is the newest and largest production mill and can be configured as dual mills or a single mill.  The VKE 3080 mill uses two 9 hp motors and with 1/4" and under feed material is capable of as much as 3 tons per hour production. Learn More

Any of the VKE mills can be run wet or dry, and configured in multiples with a rod equipped rougher mill feeding two fine grind mills equipped with steel balls, ceramic or any type of media that can be used to grind material down to sub micron particle size.

Our VibroKinetic Energy Mill is designed for ultra fine pulverization of minerals and metallic ores to release and concentrate maximum values.  The mill is simple, low cost and practically maintenance free.  Energy savings of 50-85% or more over other types of mills is attained by:

The unique energy saving spring-suspended grinding chamber which retains all of the energy applied except that used directly in grinding.


Use of a high speed type vibratory motor which increases grinding impact rate, resulting in faster grinding.


Directly attaching the vibratory motor to the mill, eliminating the need for complex mechanical drive components.
