Haver & Boecker Niagara Offers Turnkey Solutions for Primary Crushing Plant Systems

MÜNSTER, Germany (June 5, 2019) — Haver & Boecker Niagara offers rugged primary crushing plants in a wide variety of configurations for pre-crushing, secondary and tertiary crushing in the mining and aggregates industries. From design to installation, the manufacturer uses its extensive industry experience and knowledge to provide turnkey systems engineered and built to individual specifications. Haver & Boecker Niagara will work with any crusher and peripheral component manufacturers to ensure customers receive the best plant matched to their requirements.

“We’re entrenched in the mining and aggregates industries and are dedicated to each customer’s profitability and success,” said Peter Grotjohann, managing director of the German facility. “We use our industry experience and work closely with each operation to design comprehensive primary crushing plant systems with the highest level of durability, service and flexible design so each customer can find the best plant for their operation.”

Haver & Boecker Niagara offers turnkey primary crushing plant solutions through customer-oriented project support, from initial concept to the production phase. In addition to coordinating the physical plant, Haver & Boecker Niagara offers structural building engineering at the start, including verifiable statics calculation. The company features transportation management, supervision or the complete package: from assembly and electrical installation to plant start-up and optimization. Haver & Boecker Niagara also offers project management, on-site services, operating supplies, components or plant control. Operations also benefit from service and spare parts planning and service contracts.

Haver & Boecker Niagara provides crushing plant systems with a variety of components, including impact, jaw, cone or roller crushers, Haver screens or rolling screens, push feeders, apron conveyors and Haver vibrating feeders. The plant systems work with all peripheral components such as maintenance cranes, de-dusting systems, compressed air systems, hydraulics and hammers.

Customers choose from two types of systems, basic or master. Basic is the classic pre-crushing plant that uses a Haver & Boecker Niagara N-Class eccentric screening machine to relieve the primary crusher. It includes a feeder, vibrating screen, crusher and several conveyors. If needed, an additional screen deck screens stony earth either to be screened away or to be fed to production.

The master system allows customers to get the most production and profitability out of their natural mineral deposit. The system provides increased flexibility for primary crushing stages, especially with non-homogeneous natural deposits. For high quality natural deposits, the operations can use the master system to feed extracted material completely to the production. The system can screen stony soil off to a second vibrating screen for moderate natural material deposits. The system can be configured to completely remove stony soil from difficult natural material deposits.

Both systems work with the Haver & Boecker Niagara N-Class vibrating screen. The screen is perfect for scalping thanks to its smooth operation and heavy-duty design making it capable of screening as much as 5,000 tons per hour. Haver & Boecker Niagara builds the equipment with an advanced four-bearing design that minimizes structural vibration and maintains constant g-force even through fluctuating material feed rates.

Haver & Boecker Niagara primary crushing plant systems feature rugged steel construction and a robust design incorporating a durable, optimum flow, low wear and maintenance friendly chute system and integrated custom conveyor technology. Accessibility is easy thanks to engineered work platforms, walkways and stairway systems. Integrated plant control systems and data management ensure intuitive operation.

Also included is comprehensive plant documentation on CE requirements and beyond and declaration of conforming with EC directives for machines 2006/42/EG (CE). Haver & Boecker Niagara gives extensive consideration of requirements for personal safety and the environment.

Underground processing plant for fluorspar

The opening up of a new mine in Germany’s Erzgebirge (Ore Mountains) in late 2013 marked a milestone for German mining, continuing the tradition in this region, following decades of stasis. The reasons for the extraction of fluorspar and baryte are closely tied to steadily rising raw material prices on the world market. The operator, the Erzgebirgische Fluss- und Schwerspatwerke, chose HAVER NIAGARA GmbH when it came to designing and installing an underground processing plant for the mine in the Erzgebirge. HAVER NIAGARA GmbH took on the challenge to set up a flexible and economically viable processing plant (Fig. 1). Despite the limited space and the high requirements to be met by the processing plant, a tailored plant was designed (Fig. 2) that fulfils the high expectations of the operator to full satisfaction.

The processing plant roughly consists of two independent production lines, which were installed in two parallel underground caverns. In the first process stage, the blasted raw material is removed from the feed bin by means of reciprocating feeders and fed to a NIAGARA scalper (Fig. 3). This reduces the load to be processed in the downstream jaw crusher. The material from the primary crusher is conveyed on a troughed belt conveyor to a NIAGARA screen, which as well as screening off the ultrafine material, splits the material into two sub-streams to feed an X-ray sorting plant. This sorter separates the raw spar from the “dead rock” on the basis of the atomic density. The raw spar obtained in this way is crushed in a cone crusher to the necessary finished grain. The crusher discharge is sent via a downstream NIAGARA screen to a loading silo, there the raw spar is loaded onto road trucks.

From there, the material is conveyed to the processing plant above ground, where it is ground and enriched in a flotation plant and then separated into the main components baryte and fluorite. After drying, two high-grade raw materials are produced, which are then sold.

Over the next years, HAVER NIAGARA GmbH will be on hand providing services for our german customer to keep the complete plant at its best both economically and ecologically.
