Crushing victory: MB Crusher is playing to its strengths at a Riyadh lime quarry
MB proves the toughness of its tools in the challenging conditions of a lime quarry south of Riyadh
MB Crusher’s premium but productive attachments for crushing and screening loose rock and aggregates are being used to great effect in Al Kharj, a village to the south of Riyadh, Saudi Arabia.
There, MB has found a customer in Lime & Sandlime Bricks, a Saudi company and a sizeable quarry operator established in 1978 in a joint venture between Saudi industrialists and a West German lime quarrying firm.
At present, the company is deploying two MB products: the BF135.8 crusher bucket for excavators of over 43 tonnes and the MB-S18 screening bucket for excavators of between 20 tonnes and 35 tonnes, in conditions that often see the machines work at temperatures in excess of 50 degrees Celsius.
The excavators equipped with the MB attachments are being used to recover loose debris from the quarrying blasting and excavation process — which would otherwise be costly to work with — to be reused in the construction of the Riyadh Metro.
In such scenarios, the advantage of using bucket attachments to crush and screen rock in-situ is that it avoids what would be a high-cost, low-yield process to transport the broken-up material to crushing and screening units — thereby cutting down on processing costs and increasing the company’s margins.
Aside from the obvious benefits of being able to process the material in-situ, MB attachments can deliver added value from a fleet management perspective by being coupled to excavators that might otherwise stand idle — increasing the utility of the units and, in the long-term, their return on investment.
According to MB, even large operations with large standing crushing installations — such as Lime & Sandlime Bricks — are increasingly deciding to equip MB crusher buckets, which allow them to cover a wider variety of situations and processes, including work in tight spaces or those with poor access.
The largest MB attachments, including the BF135.8 crusher bucket and MB-S18 screening bucket, have also been specifically manufactured to satisfy the needs of the operators in the quarry sector, where performance is measure in terms of hourly yields and resistance to wear over time.
MB’s screening buckets can also be delivered with a variety of interchangeable screens suited to different particle sizes — allowing aggregates to be processed in carefully calibrated batches. The buckets themselves require minimal maintenance, and the processes can be carried out by the operator.
On construction sites, MB attachments can also be used to process extracted material and render it re-usable on the same project.
