The CEN-MKII introduces students to the behaviour of granular materials and is available as three units that can be purchased separately or as a complete set, as follows:
CEN-MKII-11 SOLIDS HANDLING
The equipment consists of interchangeable ball mill and Vee blender assemblies that are operated inside a protective enclosure. The enclosure, constructed from solid PVC, incorporates an electric motor with quick release coupling and manually adjustable speed control. A single-piece transparent hinged cover over the top and front of the enclosure allows access to the mill or blender and allows the user to safely observe the operation of the equipment. A safety interlock prevents the motor from operating when the cover is raised.
Ball Mill
The ball mill is a type of grinder that is used to reduce the size of solid materials using porcelain balls as the grinding medium. The ball mill can also be used to mix different powdered / granular materials. The mill supplied consists of a PVC cylindrical drum that rotates in the horizontal plane. The two ends of the drum are constructed from clear acrylic to aid viewing of the milling operation.
Vee Blender
The Vee blender is the most gentle and cost effective way to blend powdered materials together. The blender supplied consists of a shallow V shaped vessel that is constructed from clear acrylic to aid viewing of the blending / mixing operation.
CEN-MKII-12 POWDER HANDLING
The equipment consists of several different pieces of apparatus, mounted on a common backboard that is constructed from solid PVC.
Hele-Shaw Cell
The maximum stable slope of a pile of granular material is called the angle of repose and this will vary with different materials and the moisture content. The Hele-Shaw cell consists of two parallel clear acrylic plates between which the granular material is poured showing a section through the conical pile and allowing the slope to be measured. The behaviour of mixtures of solids with different grain sizes can also be observed.
Hopper Discharge
The apparatus supplied consists of a pyrex glass cylindrical hopper with a conical base that terminates in a circular outlet. A disk mounted adjacent to the outlet allows the flow of granular material through four different sizes of orifice to be tested by timed collection using a stopwatch (not supplied).
Pneumatic Conveying and Cyclone separation
It is common in industrial processing for granular materials to be moved from one location to another using compressed air as the conveyor and a cyclone to separate the material from the air stream at the final destination. The apparatus supplied provides a visual demonstration of the principles of pneumatic conveying using the cylindrical hopper as the cyclone. The low pressure created by a stream of compressed air from an external source (not supplied) through a Venturi is used to draw the granular material into the conveying system.
CEN-MKII-13 VIBRATORY SHAKER AND SIEVES
The granular materials with different particle sizes can be separated/graded using a stack of sieves with different mesh sizes mounted on a vibratory shaker. After a period of operation the different ‘fractions’ can be collected from each of the sieves and weighed using a suitable balance (supplied with CEN-MKII-00 only).
CEN-MKII-00 COMPLETE SOLIDS HANDLING STUDIES BENCH
This option consists of a CEN-MKII-11, CEN-MKII-12 and CEN-MKII-13 with the addition of a 5kg digital balance for weighing samples.
