The main advantages of the cantilever mill design over the traditional ones:
Convenient and fast delivery
Thanks to its simple assembly and disassembly, cantilever mills can be easily delivered to deposits located in hard-to-reach places and quickly put into operation. Since these mills can replace all crushing stages and the ball grinding stage (for coarse grinding), fast delivery and quick commissioning make them simply indispensable in the development of small deposits.
Reduces operating costs
The use of rolling bearings instead of plain bearings significantly increases the reliability of the mills, significantly reduces operating costs, since their maintenance is limited only to periodic replacement of grease (these mills do not have oil stations)
Convenient installation
Cantilever mills have a weight of 30-50%, and the occupied area is 40-50% less than traditional ones, they do not require multi-ton cranes for maintenance, since the most difficult repair can consist only in replacing the lining
Fast installation and commissioning
The drum shaft bearings and the drive are mounted on a single frame with factory alignment, so that installation and commissioning takes no more than 5-7 days. In addition, due to the supporting frame, cantilever mills do not require massive foundations
Increased throughput
Cantilever mills, for example ball mills, due to the increased diameter, and therefore the increased area of the living section of the lattice, have a throughput 5-8 times higher than traditional
Less balls
Due to the increased diameter of the mill, and therefore the higher kinetic energy of the balls, their size can be significantly smaller than for traditional mills and, accordingly, higher quality
Increased productivity
Cantilever mills due to smaller in-drum volume as per compared to the traditional one and the same power have a specific productivity 1.4 - 2 times higher
Reduced rotation speed
The absolute speed of the cantilever drum is 15-20% lower than the traditional one, which is a positive factor in terms of reliability
No large maintenance required
Cantilever mills are of a low-maintenance type equipment, since the main units are designed for long-term non-repair operation, for example, drum support bearings - for 50 years, shaft - for 50 years, gear bearings - for 12-15 years.
Special lining
Use of special design lining with heeled lifters increase mill productivity, especially on soft ores, by 40-70%, while energy consumption is reduced by 30-40%.
Lower lattice mass
The new lattice has a mass of 10-15% less, and therefore lower cost, stronger, higher throughput ability, which helps to reduce re-grinding.
The new ore preparation technology, coupled with new lining and gratings, can give an increase in productivity of up to 80% and energy savings of up to 50%, depending on the structure of the ore
