Transporting machines several hundred kilometres between construction sites is quite common for the Chilean company Quilín. Based in Santiago de Chile, the company has started several projects in extremely remote areas throughout Chile as part of its growth plan. Each job site places very different demands on the company and its crusher because of the terrain, varying feed materials and the various final aggregates to be produced. As part of their growth plans, Quilín decided to invest in the RM 100GO! mobile crusher.
Job site in Patagonia: 1700 km from north to south
The first challenge facing the new RUBBLE MASTER machine was the journey from Santiago de Chile to Puerto Aisén in Patagonia. The task on site: crushing river rock. Until now, this demanding material required several crushing stages and consequently several machines to produce a cubic value aggregate from the abrasive gravel. The RM crusher can do this with the built-on mesh screen in just a single pass. This results in massive cost savings for transport, because only one truck is needed to transport the crusher, the post screen and wear parts such as replacement hammers.
RM sales partner RAICO in Santiago provided training for the Quilín team on how to use the RM 100GO! with the mesh screen. The crusher was brought to Puerto Montt on a low loader, where it then drove off the low loader onto the ferry by remote control. Following the 9-hour ferry trip to Puerto Chacabuco, the crusher drove off the ferry onto another low loader – no crane was needed – and headed for Puerto Aisén. Easy logistics and the uncomplicated supply chains with RM machines are of key importance to Quilín. That is how to avoid delays. After all, the saying “time is money” applies all over the world.
Crushing and screening river rock with just one machine
Crushing river rock, river gravel and even bank gravel to form material with well-defined edges is one of the great challenges in mobile processing. The first task for the RM 100GO! was to crush 30 cm/12 inch river rock to under 4 cm/1.5 inches. The final product is used as a substructure for the airfield at the job site. This means that perfectly cuboid final aggregate was required. RM 100GO! crushing technology is perfect here. Impact crushers achieve a high crushing ratio of 10 to 1 and output a high quality, perfectly cubed product. This degree of crushing can theoretically also be achieved with the combination of a jaw and cone crusher. However, purchasing only one crusher saves money on investment costs, as well as for transport and maintenance. In addition, the RM 100GO! requires much less space on the construction site and is easier and faster to manoeuvre than a line of machines.
Perfectly cubic final aggregate thanks to flexible RM 100GO!
River rock cannot normally be assigned to one particular type of rock, it is often extremely hard and abrasive. In addition, other crushing technologies often leave smaller grain sizes uncrushed in the final aggregate. Thanks to its unique three-stage impact arm and the many adjustment options of the crushing box, RM offers the optimum settings for every material. As a result, river gravel stays in the crushing box for longer until it reaches the specified size and cubicity. This may sound complicated, but it is not, as Quilín confirmed: “The RM 100GO! is a very simple machine to operate. It is easy to maintain and configure, so we always manage to deliver a final aggregate with well-defined edges that meets requirements.”
Easy to switch between feed materials
The RM 100GO! can also be easily and quickly adjusted for other feed materials. That is why the RM crusher meets all the requirements of the Chilean customer. The result: a satisfied customer. “The RM 100GO! is a highly versatile and flexible diesel-electric crusher that is ideal for our applications in the recycling, construction, aggregate and asphalt industries.”
Our crushers in action
Der RM 100GO! ist der Star der mobilen Brecher – ein mobiles Power-Paket für jede Anwendung. Innerhalb weniger Minuten ist er voll einsatzbereit und verarbeitet rasch die unterschiedlichsten Materialien. Mit einem Eigengewicht von nur 29 t bricht bis zu 250 t Material pro Stunde.
Das Maschendecksieb wurde entwickelt, um unsere Brecher noch effizienter zu machen. In nur einem Arbeitsgang wird das gebrochene Gut auf die gewünschte Endkorngröße abgesiebt. Genauer Trennschnitt inklusive.
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.
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.
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.
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.
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.
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!.
