Quarries around the world offer spectacular sites such as Carrara marble quarry or the beautiful elliptical patterns from copper mines, plus they provide important resources for every country. Despite the differences and the great distances between them, there are two main problems that all sites have in common: managing extracted material and productivity rates. Each quarry consistently sends engineers and operators in the field to look for new solutions that can increase their profitability.
The answer comes from MB Crusher’s range of attachments designed to transform certain operating expenses to an advantage. The units are easy to use without needing specialized machines or personnel, making them immediately operational.
Sandstone, India:
Our tour starts in India, where an MB-S18 screening bucket was installed on a Kobelco SK220SD excavator in a sandstone quarry. They saw immediate results: the extracted materials were screened to select the desired output size, ready to be sold.
Gypsum, Uzbekistan:
Moving onto Uzbekistan where the MB-R900 drum cutter has been introduced in a gypsum quarry. Thanks to the unit, they easily obtained excellent material of a smaller size, suitable to be brought to a stationary crusher and increasing its hourly production. The finished product is then sold as a base for plaster.
Copper, South America:
In South America, at an enormous open-pit copper mine, the best decision was to introduce the BF120.4 crusher bucket and the MB-S18 screening bucket to the mine fleet. Both units are suitable for situations where high-level performances and large quantities of production is required.
MB’s jaw crusher is installed on a Caterpillar 336D that works day and night to crush all of the inert material, when properly screened by the MB-S18 screening bucket, is perfect to cover the holes that contain the explosives. This way, the explosion is more targeted and efficient. The larger sized materials are used to build the mine haulage roads. The advantages? With the waste material managed directly on-site, they saved time and money, which are fundamental factors for quarry or mine’s competitiveness.
Coal, India:
Inside a large coal quarry in southern India, they needed to accurately manage materials because their surface miner was unable to adjust the output size they needed. The solution came from one of MB Crusher’s units, the MB-HDS320 shaft screener bucket. They installed the unit on their excavator working and began producing 55-66 tons per hour of material ready to be used at the power plant. There are several results: reduced waste, increased profitability in the quarry, reduced operational expenses down to the bare minimum and consistent optimized productivity.
