It is no wonder that J. Koskenmäki Oy, an expert in machine contracting and property management from Hämeenlinna, is happy with the 17-ton powerhouse the company acquired last fall.
“We subjected the screen to a four-week test during which we screened fairly coarse rock material and we were impressed with what it could do. The Lokotrack ST2.3 is our first machine made by Metso, but it has to be said it was quite a safe option for us. After all, Metso’s technical support and maintenance are close to us in Tampere,” says managing director Jouni Koskenmäki, listing the company’s selection criteria.
Soil material recycling in Hattula
The new ST2.3 mobile screen is for the most part stationed at the Rahkoila clean fill dump site in Hattula. There, J. Koskenmäki processes different soil materials, recycled concrete, twigs, stumps, and sometimes also crushed stone.
The primary task of the ST2.3 is to remove any rocks and roots from excavated land material for soil production. The pure and screened soil is delivered to municipalities, parishes, and private consumers.
In addition to soil, the ST2.3 has already separated fines from recycled concrete and also screened pre-crushed stone.
