MB Crusher

Spectacular and famous sites such as Carrara marble quarry or the beautiful elliptical patterns from copper mines, quarries provide important resources for every country.

Despite the differences between each location 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 operational expenses to an advantage. The units are easy to insert 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.

Gypsum, Uzbekistan

Moving onto Uzbekistan where the MB-R900 drum cutter has been introduced in a gypsum quarry. Due 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 wall paint.

Copper, South America

In South America, at an enormous open copper mine, the best decision was to introduce the BF120.4 crusher bucket and the MB-S18 screening bucket to the mine. Both units are suitable for situations where high-level performances and where producing large quantities are required.

MB's jaw crusher is installed on a Caterpillar 336D and works day and night to crush all of the inert material. When properly screened by the MB-S18 screening bucket it is perfect to cover the holes where the explosives were placed inside. This way, the explosion is more targeted and efficient. The larger sized materials is used to build soft roads inside the mine.

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, specifically the MB-HDS320 shaft screener bucket.

The only thing they needed was the unit installed on their excavator working inside the quarry to produce 55-66 tons per hour of material that's 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.
