It has three quarries within 100km along the A23 highway. The lsquoSan Blasrsquo and lsquoVentorrillorsquo quarries produces limestone and the lsquoEl Poyo del Cidrsquo quarry produces siliceous ballast.

Ventorrillo is Emipesarsquos oldest quarry, operational since 2000, and El Poyo del Cid, where the initial building works started just two year ago, in 2017, is the youngest. In 2019, the company became the proud owner of the newest Metso MX3trade Multi-Action cone crusher, the first in Spain.

Back in 2013, Emipesa started operating a primary Nordbergreg C125trade jaw crusher with a Metso Rockbreaker MB352trade boom amp hammer and a secondary Nordberg HP200trade cone crusher. In 2014, they bought an additional Nordberg HP300trade secondary cone for a big contract, to produce aggregate for a 15km-long road to be built between Zaragoza and Soria.

The extremely abrasive quartzite aggregate that Emipesa processes led to shorter liner lifetimes and Emipesa having to stop production to adjust the crusher settings seven times a day every 1.5hr. Each stop represented 15 minutes of lost production time, adding up to about 100 minutes of downtime every day and, in Emipesarsquos case, 16 days per year.

Knowing that the site produces 2000-2200 tonnes of aggregates a day and a tonne of aggregates is sold for around Eur 9, the cost of this downtime represented close to Eur 290,000 per year.

Knowing about Emipesarsquos adjustment problem and the short lifetime of the liners, Metso started laboratory rock tests at the Metso factory in Macirccon, France the liners of the HP200 should have a wear life of 180 hours. As a result of the tests, Metso recommended Emipesa to reduce the speed of the crusher from 850rpm to 700rpm.

Two-thirds of the quartzite aggregate product produced at the site is subsequently used in concrete and asphalt for regional construction.

Rudus Oy, one of Finlands leading crushing contractors, will complete a major project in Inkoo in May, during which a total of 2.5 million metric tons of marine ballast will have been crushed.

The work is being undertaken with a stationary plant from Metso with an hourly capacity of 600 metric tons. The plantrsquos production level was ensured with two new ES screens, new MX series jaw crusher wear liners and GP500S cone crusher, which was delivered last year.

LdquoThe marine ballast was crushed at a fast pace, and the plant had to be running whenever necessary. At best, there were four ships at the Port of Inkoo retrieving cargo, which meant that we always needed to have some buffer inventory in hand,rdquo says Kimmo Leppikangas, production and development manager at Rudus Oy.

LdquoThis project has lasted for more than two years, and it has presented plenty of challenges. Wersquove always received quick expert and maintenance support from Metso when needed. We also have a joint meeting with Metso every month at which we can freely discuss any matters that have arisen.rdquo.

Located right next to the Port of Inkoo, thenbsp plant refines hard and relatively abrasive granite. The blasted rock is transported by truck to a feeder leading to a C125 primary crusher.

The jaw crusher, dating from the 1980s, is still operating reliably. For marine ballast production, the closed side setting is 150 mm. From the jaw crusher, the pre-crushed material is taken to Metsorsquos second-largest GP series cone crusher, a Nordberg GP500S. The S in the model name stands for secondary, and these GP Secondary cone crushers are known for their extra-large feed opening and steep cavity profile.

The cone crusher, delivered last summer, uses a closed side setting between 60ndash70 mm and stroke length of 25 mm. The wear liners feature Metsorsquos Coarse chamber profile. This is the first GP500S secondary cone crusher in Finland with the Metso Metrics remote monitoring system installed. The system wirelessly transmits the key data related to the crushing process.

After the secondary cone crusher, a Metso A132 double-deck screen separates 22ndash100 mm marine ballast. The screen uses a plate on the upper deck and a rubber mesh on the lower deck.

The weight of the crushed aggregate is an important factor in the production of marine ballast. The bulk density must be sufficient to resist the currents on the seabed.

During the project, 70 of the plantrsquos entire production has been marine ballast. The remaining 30 is forwarded for fine crushing and screening. Here, two new Metso ES series screens, an ES302 and an ES403 model, handle important tasks with GP550 and GP300 cone crushers.

The products can be divided into two kinds 0-7mm and 7-27 mm. Both of them are high-quality aggregates. The aggregates produced in the first stage of the project are used in producing the commercial concrete, mainly selling to Guangzhou, Dongguan, and Shenzhen. The aggregates produced in the second stage of the project are used as the pavement material of high-speed way.
