A Candid Chat with Metso Head Olli Vaartimo

By Bill Welgoss

The biggest manufacturer news in 2001 was the acquisition of Svedala by Metso Minerals. AggMan was invited to conduct an exclusive interview with Metso’s President and Chief Executive Officer Olli Vaartimo to discuss what the acquisition means to the industry, and what it means to Metso Minerals.

AggMan: How far do you think consolidation will go on the manufacturing side of the industry?

Olli Vaartimo: It is very difficult to say. If you talk about crushing and screening, my feeling is it will further consolidate to some extent. But, I think it will remain a somewhat a fragmented industry. There will be local manufacturers; various types of more specialized products. But, when it comes to providing full-scope offerings to major aggregate producers—that part of the business may still consolidate to some extent. You know well that the whole aggregate industry has been consolidating. And I think the consolidated equipment suppliers will be serving the consolidated part of the aggregate industry. Then, there will be smaller equipment suppliers focusing on certain niches, which will be then focusing on serving smaller local aggregate producers.

AggMan: It is interesting how markets worldwide develop at different times. Mobile crushing has developed pretty well in Europe, and now it is just starting to do so here.

Vaartimo: Mobile crushing has been in North America for a long time already, but it has been mainly wheel mounted. It has not been self-contained, track-mounted machinery. Metso minerals introduced the track-mounted concept in the late 1980s in North America. The European market accepted it in the 1990s, and in the late 1990s and early 2000s it looks like the U.S. market is accepting that concept more and more.

AggMan: Road contractors first caught on to using track-mounted equipment to recycle materials on site. But, what forces are driving this trend in the aggregate industry?

Vaartimo: In Europe, by having in-pit crushing installations, you can eliminate, for instance, truck transportation inside the quarry. I think we will be seeing more of the same in North America because it creates less noise and dust and is thereby more environmentally friendly. Big trucks always generate these things, and also require more manpower, if you have a totally fixed operation. Part of the attraction of track-mounted equipment is also the general flexibility. You are able to drive the track-mounted plant to the bench and feed it with a shovel.
You are seeing an evolution in track-mounted equipment, not only in handling different stages of crushing, but also in screening. We have a new product the ST-171, a track-mounted screening machine. We also have an ST-620 screening machine coming on the market soon. With tire-mounted equipment, there still is other equipment involved in moving it. Track-mounted is so easy. Fire it up, move it with remote control, crush and convey to a track-mounted screen and you have your product. A high level of flexibility is what we are talking about here.
We have several plants in Europe and Asia already that are three-stage track-mounted systems. Aggregate producers can also use a contractor with a tracked system to take care of fairly sophisticated crushing, and this is increasing flexibility, too.

AggMan: What was the driving force behind the acquisition of Svedala?

Vaartimo: The main driver was to gain critical mass to develop total lifetime service and support to customers. Being able to sit down with customers in the beginning and start to develop together the whole crushing process—or to sit down with customers and see how we can improve the performance of their crushing plants.
We want to provide the total lifetime aftermarket service as well. We enhanced our presence to customers through the acquisition of Svedala distribution units. On top of that, Svedala had a number of interesting aftermarket products—screen media, conveyor components—which we didn’t have. Now we have those products, so we can justify a presence in more locations.

AggMan: Explain the branding of Metso Minerals products.

Vaartimo: Crushing and screening equipment is all Nordberg. Compaction and paving equipment is Dynapac. Screen media and wear liners is Trellex. Svedala will be mainly used to brand some mining products.

AggMan: What do you want the name Metso to mean to the U.S. aggregate industry?

Vaartimo: We are targeting Metso Minerals together with our distributors as a full-scope supplier to this market. We are going to strengthen our, as well as our distributors’ capabilities to supply customers total crushing plants and systems solutions. We will help them to improve current processes. It is a capability we fully developed in Europe, and now we want to bring it to North America. We also want to be a full-scope aftermarket service and aftermarket product supplier to our customers. In addition to providing aftermarket services, we will have a broad range of aftermarket products from crushing liners, to screening media, to conveyor components, and so on. That is a clear target. Already 40 percent of our business comes from aftermarket products. Our plan is to further strengthen it.
I think our competitive advantage will be our ability to provide full-scope support to customers. I’m expecting more customers will be subcontracting a big part of their maintenance operations to suppliers like Metso Minerals. For this, you need critical mass and the confidence to take that kind of responsibility. To do this in North America, we will have to work closely with our distributors. We will have to train their people and give them the tools to provide those services.
Another area we will develop in coming years is automation intelligence, and we have a good opportunity in that area because of Metso Automation, our sister division in Metso Corporation, which consists of 6,000 people who are experts in automation. Metso Automation has been mainly supplying process automation, process control for the pulp and paper industry as well as energy and chemical industries. Our plan is to leverage that experience and incorporate more process control automation intelligence into minerals processing equipment.

AggMan: How close is Metso to realizing its goal as a full-scope processing solutions provider?

Vaartimo: It has been just over six months since closing, so our focus has been on consolidating operations. It would still take another six months to complete, so after this summer, we will start to put more emphasis on developing our future capabilities and skills.

Andreas Primary handles 34-in. shot rock
Cedarapids introduces an Andreas-type horizontal shaft impact crusher, the 1516. The unit has an unobstructed feed opening of 52-in. x 65-in., and according to the company, can handle up to 34 in. aggregates, C&D debris and concrete and asphalt recycle material. With a reduction ratio up to 20:1, the 1516 reduces feed material to 7-in. minus at throughput capacities up to 600 tph, says Cedarapids. The 61-in. diameter x 64-in. wide high inertia rotor is available in a three- or four-bar design. Other items included patented huckbolted stub shafts, spherical roller bearings with taconite seals and backer bars to secure 5-in. thick single piece impeller bars. Bars are available in manganese or steel alloys, and provide three-turn wear. A patent pending quick-turn wedge system offers easier bar rotation and replacement, according to the company.

Komatsu Loader boosts Power/efficiency
According to Komatsu America International Co., major engine power increases and fuel consumption decreases boost productivity and performance for its WA450-5 wheel loader. Powered by a 261-hp Komatsu engine, the WA450-5 is more efficient with reduced cycle times and fuel consumption.The SAA6D125E-3 engine is designed to provide optimum combustion of fuel at both low and high speed/power applications. Engine torque has been increased 19 percent. Fuel consumption has been reduced 15 percent. An optional lock-up torque converter saves fuel in both load-and-carry and hill-climb operations, according to Komatsu. When activated, the torque converter will lock-up when the travel speed reaches 6.8 mph in third gear and 13.0 mph in fourth gear. Performance features include two engine-operating modes—normal and power. A dual-speed hydraulic system matches hydraulic demands to work conditions. The hydraulic system also provides more rim pull when using the transmission kickdown switch. The automatic transmission enables selection of manual shifting or three levels of automatic shifting modes (low, medium and high).The four forward and four reverse gears permit travel speeds up to 21.7 mph in forward and 22.4 mph in reverse. The cycle time to raise, dump and empty the bucket is 11.1 seconds, according to the company.
