In mining, a jaw crusher is used to reduce large rocks into smaller pieces of rock, like gravel. A jaw crusher is usually the first part of a system of several crushing machines that break down the material into the desired shape and size. Large rocks are inserted into the mouth of the crushing chamber, where hydraulic pressure is applied to the material to crush it into a roughly uniform smaller size. There are essentially two types of jaw crushers: overhead eccentric and double-toggle. Each type of jaw crusher uses a different method to power the crushing chamber of the jaw crushing unit.
Along with the scientific development, industries like railway, roadway, chemical engineering, construction materials develop rapidly. Meanwhile, the industry of sand aggregate also develops in a rapid way, also in a specific and intensive way. Basalt is the often seen aggregate in natural world. Due to the features of great hardness, strong resistance to wear, corrosion and impact force, basalt is commonly used for industrial purposes.

The HPGR product, corresponding to the best condition, is submitted to the standard Bond ball mill grindability test. The Bond ball mill grindability test measures hardness as an index, regardless of the feed size, so it does not give credit for the additional fines. Therefore, the index itself is ignored in the analysis and the results are assessed in terms of throughput rate or specific energy requirement.
The people said Giga Metals had also discussed the possibility of a deal with other automakers including Germany's BMW and Mercedes-Benz, a subsidiary of Daimler.
The site is one of the oldest known gold mines in the world, with scientists estimating that gold mining operations first began here sometime in the 3rd to 4th millennia BC. Mining operations have recently recommenced, much to the despair of local cultural and environmental conservationists.
Under the terms of the MOU, Ivanhoe has appointed R&H Rail to conduct a front-end engineering design study to assess the scope and cost of rebuilding the spur line from the Kipushi Mine to the main Lubumbashi-Sakania railway at Munama.
