Fuel savings of over 100,000 euros per year
Finsveen Maskin was among the very first companies worldwide to start operating the Lokotrack LT220D in August 2014. In ten months, more than 2500 hours have been clocked and some quarter of a million tons of aggregates crushed and screened.
Rune Finsveen expects to save 60,000–70,000 liters of fuel per year with the new LT220D. With the average price of diesel about 1 EUR/liter in Norway, the total fuel savings will range between 60,000–70,000 euros per year. At the same time, he will get 25-30 tons more production per hour compared to the LT1100.
Finsveen Maskin concentrates on the contracting of secondary and fine crushing jobs. It operates in a manner commonly practiced in Norway: a dump truck feeds a static hopper silo, from which a conveyor moves the material up to the LT220D’s vibrating feeder.
The GP220 cone crusher on board the LT220D is operated at a 16-mm closed side setting, providing capacity of about 130 metric tons per hour. The patented, centrifugal lifting conveyor takes crushed materials back to the screen, saving a lot of space.
Normally, the LT220D produces end products of 0–4 mm, 4-8 mm, 8–16 (16-22) mm, 8–11 mm and 11–16 mm, with an additional mobile screen further producing 0–2 mm, 2–5 mm and 5–8 mm grades.
Screening jobs from the age of 14
Runar Finsveen’s career in the crushing and screening business has already spanned more than 25 years. He actually started his first screening job at the age of 14 and was running a crushing plant just one year later.
Runar founded his first company at the age of 19, working with an excavator and a truck. Finsveen Maskin was established after a company merger in 2007. Today, the company has 22 employees and executes contracts around the village of Bø, south of Norway’s capital city of Oslo.
Before the LT220D, Finsveen Maskin operated Lokotrack LT105 and LT110 jaw plant models for primary crushing and an LT1100 for fine crushing. This year, the company’s secondary and tertiary crushing will produce 270,000 metric tons, and it has plans to increase it to 300,000 – 350,000 tons by 2016.
Daily service breaks ensure smooth operation
Normal working days at Finsveen Maskin tend to run about 12 hours long and usually include a one-hour service break. This way, the company ensures smooth, efficient operation and avoids unexpected breakdowns. The fact that the diesel engine on the LT1100 was operated more than 16,000 hours without opening is a good indication of the effectiveness of the company’s service culture.
“The service requirement for the LT220D seems to be rather minimal. We try to handle it on our own, but we do use Metso experts when necessary. We also get all our crusher wear parts and screening media from Metso,” Runar Finsveen says.
The trust in Metso was seen already when signing the purchase deal for the new Lokotrack LT220D:
“At that point, the machine was still just a drawing, but we trusted Metso Norway. Since delivery, the machine has performed well and without major problems. In the future, we are expecting Metso to react quickly to even the smallest concerns we encounter,” Runar Finsveen adds.
*Metso Outotec was formed July 1, 2020 when Metso and Outotec merged into one company. This case study has been written prior to the merger under the old company name.
