In March 2020, an electric RM 60E with an RM CS2500 post-screen was delivered to Manamah, Bahrain to recycle residues from concrete production. The customer is highly satisfied with his alternative to cost-intensive aggregate purchases and imports from the mainland.

East of Saudi Arabia and west of Qatar is a small group of islands in the Persian Gulf, which is known worldwide for its high-quality oyster pearls. The Kingdom of Bahrain, which mainly consists of desert, is also home to the Al Kobaisi Group with over 1,500 employees. Besides automobile construction, real estate, tourism and media production, the Al Kobaisi Group specializes in construction and the production of concrete blocks. Today, they are one of the three largest concrete manufacturers in Bahrain. Precisely there, or rather in the capital Manamah, an electric RM 60E recycles residues from concrete production together with an RM CS2500 post-screen since spring 2020.

 

The last Bahraini quarry was closed five years ago, which is why the company had to rely mainly on cost-intensive aggregate imports from the United Arab Emirates. Thanks to the RM machines, an alternative was created that not only saves money, but also makes the customer Al Kobaisi Block Factory much more flexible: concrete residues are now electrically recycled on site and prepared for the production of new concrete blocks. The purely electrically driven RM 60E impact crusher produces very clean end material that can be recycled entirely.

 

For the Al Kobaisi Group it’s the first crushing and screening plant ever to be invested in. After thorough research, the decision in favour of RUBBLE MASTER products was quickly made. The compact size and semi-mobility of the impact crusher as well as the excellent throughput capacity and reliable final grain quality convinced the customer. The decision was made to purchase the electrically driven and much more environmentally friendly version of the RM 60, as there is a high level of fine dust pollution in Bahrain.

 

The Al Kobaisi Group now also benefits from the excellent local after sales service. With the purchase of a RUBBLE MASTER product a long-term partnership begins. RM Lifetime Support with its dedicated, highly trained dealer network ensures the best possible support – throughout the entire machine life.

Our crushers in action

RM 60

The RM 60 is the most compact RM crusher and the ideal choice for processing smaller quantities for businesses which are looking to expand their activities and increase profits. Like all RM crushers, the 12 tonne model can also be combined with high-performance pre-screens and post-screens.

RM CS post-screens

The powerful linear oscillation screens in the CS series transform your recycling material and natural rock into high quality standardised grain sizes. Even at high throughputs, these post screens feature 100% screening accuracy between the fractions.

Natural rock

Crushing at a high output and low wear, and that in every possible and impossible location, is not an issue for RM crushers. They manage to generate the highest quality value grain from natural stone on site. Depending on the desired combination of machinery. The end result is always cubic aggregate.

Abrasive rock

Quartz gravel, granite and riverbed gravel are not easy to process because high levels of quartz cause high wear. However, RM crushers are designed for such materials: thanks to their compact size they can achieve high throughputs even in tight spaces, producing valuable aggregate directly on site at all times.

Crushing gravel with 90% quartz content

Processing 24,000 tons of gravel with a quartz content of around 90 percent to produce 0-32 mm value grain
– that was the right challenge for the RM 100GO!. The mobile power pack with its wear-resistant hammers rose to this challenge in the Vienna basin extremely economically. Excavator and loader drivers are impressed.

Endurance in riverbed gravel

Building roads to connect to eastern Mexico was difficult because of the problematic terrain. It was necessary to prepare materials on site because of the remote locations of the construction sites. The RM 70GO! is ideal for challenges like this. Its manoeuvrability make it a perfect machine.

High demand for crushed sand and grit

The Swiss company Mühlebach AG has been successfully processing gravel for 40 years. As pioneers in this business field, they demand machines that are state of the art. They have now added an RM V550GO! to their fleet of machines in order to meet the demand for crushed sand and grit.

Impressive RM V550GO! performance in Argentina

At the beginning of the year the RM V550GO! made light work of transforming 0-200 mm river rock into fine 0-19 mm value grain. The awesome capacity and low diesel consumption were key in the Argentine company’s decision to purchase the RM V550GO!.
