projects. These vertical stirred mills were originally developed in South Africa to produce fine pigments. This early development was carried out by Deswik (Pty) Ltd. In 2011, the technology was advanced through the establishment of a joint venture between Deswik International Limited and Knelson (a corporate partnership).

Steady state conditions were achieved by maintaining the relative standard deviation (RSD) of the circuit operating variables such as AG/SAG throughput, cyclone feed flow rate, cyclone pressure, mill power draw and water addition below 5%. The plant was held at steady state condition for at least two hours, prior to conducting a survey. 2.1.

The HIG mill is available in different sizes with installed capacities ranging from 132 to 5000 kW (Astholm, 2015). The FL VXP mill was previously known as the Knelson-Deswik mill. The shaft is fitted with disc type agitators.
As horizontal ball mills show decreasing efficiency as grinding sizes are finer than 50 m, this work shows regrinding equipment alternatives to ball mills focusing on vertical mills. A number of survey campaigns were carried out on four industrial operations in which vertical mills were installed in the respective regrind circuit.
" kimberlite " means a volatile-rich, potassic ultrabasic rocks with highly variable textures and mineralogic compositions that are one of the primary hosts for diamond deposits. Kimberlite is a hybrid igneous rock crystallised from a molten liquid (kimberlitic magma) originating from the Earth's upper mantle.
