The Bond Index conforming rod charge consists of: 6 rods of 1.25" diameter and 21" length. 2 rods of 1.75" diameter and 21" length. The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.

The Hardgrove test is a standard method used wide-ly in the coal industry. To determine the relative grindability of coal, i.e. whether it is easy or difficult to pulverize, the Hardgrove grindability index (HGI) can be estimated from the test. A higher index indicates the coal is easier to pulverize.

The grindability rating is good. Soft steels (annealed plain carbon steels) grind with relatively low power consumption. Aluminum-oxide wheels are satisfactory, and the grinding ratio is quite high, but surface damage may be encountered. As a group, these materials are rated as having good grindability.

Enormous quantities of coal must be ground as feed to power generation facilities. The energy cost of grinding is significant at 5 to 15 kWh/ton. If grindability could be increased by preheating the coal with waste heat, energy costs could be reduced. The objective of this work was to determine how grindability was affected by preheating. The method was to use population …
