Bearings
The flaker drum is mounted in two bearing pedestals with split roller bearings and bearing cartridges to facilitate bearing replacement without the removal of either the drum from the machine or main drive components from the drive end trunnion.

Drive
The drum is rotated by electric or hydraulic variable speed motor, through a proprietary reduction gear box where required, with a spur gear and pinion drive to the flaker drum.

Knife
The doctor blade or knife which removes the product from the surface of the drum may be of cast steel, chrome steel, beryllium copper, phenolic resin laminate, etc., depending upon the particular application. The knife is rigidly clamped to a cast iron, coated cast iron, or cast stainless steel knife bar which is mounted in front of and across the whole length of the drum. Loading of the knife onto the drum surface is normally effected by means of pneumatic cylinders located at each end of the knife bar.

Trays and Auxiliary Rolls
Feed trays and auxiliary rolls are manufactured to the relevant BS or ASME code in either carbon steel, stainless steel, or special corrosion resistant metals such as nickel/chrome alloy steel or titanium. For the majority of applications where the feed tray or box has to be heated to prevent solidification or the product, heating may be provided by steam, thermal oil, or electricity.

Enclosures
Simon Drum Flakers are supplied either as open units, for non-toxic materials, or totally enclosed. Enclosures range from simply "dust tight" to pressurised casings, complete with bursting discs, capable of operating under inert atmospheres. Materials of construction range from carbon steel to nickel/chrome alloy steels. All enclosures are provided with access/inspection panels with the necessary safety interlocks for safe operation and ease of maintenance.

Ancillary Equipment
Units can be supplied complete with feed control and distribution systems, flaked product chutes and breakers, product conveyors, product and/or coolant temperature controls and fume removal systems.
