We also supply Ball Mills, SAG Mills, AG Mills and Rod Mills. The largest gear driven mill we supplied was an 18 MW SAG mill for a project into Australia.

Does your product line include rod mills?

Yes, we do manufacture Rod Mills as part of our mill range. These can also be Skid mounted.

Are you able to quote to our company specifications?

Yes, mills are sized according to client’s metallurgical information supplied. We consult extensively with you, in order to provide the optimum solution. We also abide by all your mechanical and electrical requirements. As a standard, we adhere to the Anglo American specifications for Grinding Mills.

What are typical delivery times for the various sizes of mills?

Delivery times are dependent on a number of factors including mill size, procurement source and workshop loading.

We offer both new and refurbished mills, so if you have a time constraint, a refurbished mill may be an option to consider.

Depending on mill size and scope of supply – Refurbished mill supply can vary between 8-20weeks. New mill supply can vary between 26 – 48weeks based on the factors mentioned above.

Are warranties offered?

Yes, all new mills are offered with full OEM warranties.

Note that refurbished mills can be offered with warrantee’s equivalent to a new mill to manage client operational risk that is typically associated with pre-used equipment.

What information do I need to supply in order to get a mill sizing and quotation?

We require a minimum of the feed size (F80), product size (P80), Bond Ball Mill Work Index (kWh/mt), feed rate (tons/hr) and Ore Specific Gravity (t/m). However, we would prefer to have more detail so that a proper mill sizing assessment can be completed. Please complete the attached form with as much detail as possible.

Can you offer milling circuit simulation/optimisation at the design and operating stage of the concentrator plant?

Yes, we can assist with optimisation. To achieve this at both the design and operating stages, we will require some representative sample for specific comminution test work. The test work will entail industry standard tests such as the Bond Rod Mill Work Index, Bond Ball Mill Work Index, JK/DWi tests and then some specific batch mill tests. The results of the test work will then be used to determine the parameters required for Simulation. The simulation can then be used to size an entire comminution circuit including crushers (Jaw, Cone and HPGR), screens, SAG/AG mills, Rod Mills, trommels, classifiers, Ball Mills, Pebble Mills and the size-by-size mass balance generated by default can be used to size pumps, pipelines, liners, screens and water lines.

Do you offer second hand or refurbished mills?

Yes we certainly do, please enquire for more details or visit our website for a current listing of available mills in stock.
