Quarry upgrade
A major project Mirfo SRL has been involved in recently has been the design and installation of a bespoke aggregate plant at Luscan Com SRL’s Batuta Quarry, which the company acquired in 2017 and has since produced 8 million tons of mainly diabase aggregates. Due to diabase’s structure, it is ideal when crushed for use as a construction aggregate. This has led to rock from the quarry being used on some of the largest road and railway construction projects in Romania and, increasingly in Hungary.
Since acquiring the Batuta quarry in 2017, Luscan has invested in the facilities, distribution points, haulage and production equipment. It now has three production lines, all with the necessary loading and transport equipment. However, in 2023 it was decided to update the plant with the construction of a new production line. The new line has been designed to produce the same amount of aggregates, but with 40 % lower fuel consumption than at present so as to provide a positive impact on the environment. At the same time, the haulage loading system will be automated, thus dispensing with some front loaders, which will further lead to a significant decrease in CO2 emissions.

Productive modern solution
Due to its excellent reputation for supplying some of the most productive, reliable and environmentally friendly crushing and screening equipment on the market, Mirfo was invited to provide a solution for the new production line. Luscan required new equipment for its entire primary, secondary, tertiary and quaternary crushing. Along with this, the company also required screens and conveyors to produce 0/4 mm, 4/8 mm, 8/16 mm, 16/22.4 mm, 31.5/50 mm, 0/63 mm, and +63 mm fractions to be sold as the quarry’s main products. These products will then be used for asphalt production, road and railway construction along with concrete and concrete precast production.
In order to ensure that Luscan would be provided with the best possible solution, Mirfo contacted QMS for advice on the most suitable equipment. After consulting with QMS process experts, Mirfo supplied a selection of QMS cone crushers, screens and associated equipment. The full selection consisted of three cone crushers (B6, B4XC, B4); three 2 x 7 m 3D screens and one 2 x 6 m 2D screen.
The QMS B-Series XC models are purpose designed for secondary crushing applications, boasting a significantly large intake capacity relative to their size, a feature attributed to their uniquely long crushing chamber. To optimise operational economy, the extended chamber is divided into three sections: the upper concave, lower concave and mantle. These sections can be exchanged at different intervals, enhancing both efficiency and adaptability.
The QMS B-Series cone crushers stand out with their unique hydraulic system, a hallmark of innovation in the field. This system provides automatic overload protection by allowing the head assembly to drop, facilitating the safe passage of tramp iron and other non-crushable materials. This feature is particularly advantageous for maintaining operational efficiency and protecting the crusher from potential damage. Another notable feature is the liner design. The liners do not require any backing material like plastic, epoxy or zinc. This design choice significantly reduces maintenance time as there is no need for mixing, pouring or waiting for curing processes. It also enhances safety for maintenance staff, a testament to QMS’s commitment to both efficiency and safety.
