Testwork: Bond crushing work index - SAGMILLING.COM

The Bond low-energy impact crushing work index (more informally, the Bond crushing work index) is not as common as the Bond ball mill work index, and it is a notoriously noisy test.. The test is a 'per-specimen' test where individual specimens of prepared rock are hand-picked by the test operator and placed into the apparatus.

Geometallurgy - Wikipedia

Geometallurgy relates to the practice of combining geology or geostatistics with metallurgy, or, more specifically, extractive metallurgy, to create a spatially or geologically based predictive model for mineral processing plants. It is used in the hard rock mining industry for risk management and mitigation during mineral processing plant design. It is also used, to a lesser extent, for ...

Understanding Comminution: Compression versus impact crushing

As a basic rule, impact crushing is suitable for rocks with a low work index (<12) as well as low silica (<20%) and moisture levels (<5%). Rocks with these characteristics are soft and non-abrasive, and easily broken within the crushing chamber, keeping wear rates at a minimum, and producing high reduction ratios with a better-shaped end product.

SIZE REDUCTION BY CRUSHING METHODS

All operations in size reduction, both crushing and grinding are of course determined by the feed characteristics of the minerals (rock/ore) moving into the circuit. The key parameters we need are the "crushability or grindability", also called work index and the "wear profile", called abrasion index. 4.0 Crushing of rock and minerals:

Bond Work Index - an overview | ScienceDirect Topics

The low energy crushing work index laboratory test is conducted on ore specimens larger than 50 mm, determining the crushing work index (Wi C, CWi or IWi (impact work index)). The rod mill work index laboratory test is conducted by grinding an ore sample prepared to 80% passing 12.7 ...

Metcom Expertise - Metcom Technologies

So the Work Index of this circuit is the equivalent amount of energy (W) it would use to reduce this ore from a very large size to a P80 of 100 um. For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large ...

Aug 18, 2020· As a kind of basic first rule you could say: Impact crushing is suitable for rocks with a low work index (<12) as well as low silica (<20%) and moisture levels (<5%). Rocks with these characteristics are soft and non-abrasive material, which can be broken easily within the crushing chamber while keeping wear rates at a minimum and produce high ...

Bond Work Index Tests - Grinding Solutions Ltd

The Bond Low-Energy Impact test can be used to determine the Crusher Work index (CWi), also known as the Impact Work Index. The test determines the impact energy at which a specimen fails and allows approximation of net power requirements for sizing crushers. The open and closed sized settings for given product sizes can also be determined.
