Eesti Killustik Opened a New Plant at the Rõstla Limestone Quarry with the Support of Apeco
Since April of this year, a new crushing and screening line has been operational at the Rõstla limestone quarry, where Eesti Killustik OÜ produces various aggregate fractions. The newly completed plant is the latest production unit within the company’s quarry network and one of the most modern surface mining complexes in Estonia.
A high level of automation ensures full traceability and digital control of the entire production process. Under nominal conditions, the line is capable of producing up to 300 tons per hour of different aggregate fractions, making it a high-capacity production unit in the Estonian market.
Modern Crushing and Screening Technology
The plant’s technological solution has been carefully designed to ensure maximum productivity and reliability.
The equipment includes:
- an apron feeder ensuring uniform material feed;
- a roller screen that removes fine fractions from blasted rock mass before entering the crushing chamber;
- a 200 kW impact crusher for primary crushing;
- two-stage screening for precise separation of aggregate fractions.
All line components are equipped with walkways to ensure maximum safety and to simplify maintenance and servicing.
Digital Control and Full Traceability
The completed production unit stands out for its high degree of automation. The production line is controlled from a separate operator room, where the entire process can be monitored via cameras and control systems.
The digital solution enables:
- real-time production data collection;
- data analysis and archiving;
- accurate control of production volumes;
- continuous process optimization.
Even the hydraulic hammer is operated using camera systems, improving both safety and operational efficiency.
Apeco’s Role in the Project
Apeco was responsible for overall project management and consultancy. Our scope of work included:
- development of the initial concept design;
- manufacturing and installation of the main conveyors;
- production and integration of the main line conveyor scale;
- development of the complete technological solution in cooperation with the client.
Apeco engineers worked closely with the client to create a solution that meets both current production volumes and future expansion needs. Equipment and technology were selected based on the final concept, ensuring system reliability and scalability.
A Significant Step in Eesti Killustik’s Development
The completed project marks an important milestone in the development of Eesti Killustik’s production capacity. The new plant supports the company’s capability to produce more than 1,500,000 tons of construction aggregates annually and strengthens its position in the Estonian market.
Eesti Killustik OÜ (formerly Põltsamaa Graniit OÜ) has over 50 years of experience in mineral extraction and construction material production. The company’s main shareholders are Levalex Invest, backed by entrepreneur Andres Lõhmus, and Ambient Sound Investments through Balti Karjäärid OÜ.
A Modern Mining Complex as a Future Standard
The new crushing and screening line at Rõstla demonstrates how modern automation, well-designed technology, and strong project management can create an efficient and future-proof production facility.
