ball mill, further demonstrating the utility of DEM simula-
tions in the design process.
The MonoRoll prototype was retrofitted in an existing
ball mill shell. A 44” diameter and 60” long, 1935 vintage
mill at Corem’s piloting facility was selected for this pur-
pose. In September 2020, A new pedestal with middle tire
support rollers was designed based on the DEM structural
force balance analysis. (Figure 6). The pedestal assembly
featured axial restraint rollers that acted on the sides of the
middle and discharge-end shell tires to limit the mill’s axial
movement as a safety feature in this prototype.
Final detailed design of the CAHM machine, as
depicted in Figure 7, was manufactured at Anmar
Mechanical in Sudbury, Canada, and installed at Corem’s
facility in Quebec City, Canada. The CAHM prototype
is 6.28 m high, 7.96 m long, 4.44 m wide, and weighs
approximately 27,000 kg. CAHM’s detailed design and
structural analysis were based on DEM simulation work
and were carried out at Comminution and Transportation
Tech. Inc. (CTTI). The CAHM Mark 1 prototype was com-
missioned in August 2022. The testing program, including
minor design modifications, is still in progress supported
