    NIAGARA Primary Crushing Plants & Systems

    The Niagara Turnkey Plants improve the screening performance of customers all around the world

    We offer rugged primary crushing plants in a wide variety of configurations for pre-crushing, secondary and tertiary crushing. Our wide range of services gives you the best solution for any industrial project. Whether that means helping you increase efficiency, minimize costs, improve safety or reduce environmental and economic risks, our job is to provide the first-class service and technology to help you get the job done.

    Primary Crushing Plants

    The scalper is one of the main components of each primary crushing plant. With the scalper your plant will be more efficient, low-wear and more productive. HAVER NIAGARA® eccentric screening machines are perfect for scalping because of their heavy-duty design and smooth running. We combined our experience since 1930 with the supplementary components of our suppliers and realize complex plant projects according to our customers needs.


    Pre-crushing Plant Basic

    The classic pre-crushing plant serves to relieve the primary crusher by using a HAVER NIAGARA eccentric screening machine. If needed an additional screen deck allows the screening off of stony earth. If the screening material is unsuitable
    for further processing, it can then be directly screened away.  If the natural material deposit or the application possibilities should improve, then the material can be fed to production.


    Pre-crushing Plant Master

    To get the most out of your natural mineral deposit, HAVER & BOECKER NIAGARA developed the MASTER system. It allows you to derive the greatest possible flexibility and profitability for your primary crushing stages, especially with non-homogeneous natural deposits.

    Primary Crushing with a view to the future

    The world’s consumption of raw materials is set to nearly double by 2060. As the global economy expands and living standards rise, the pressure on the environment will double from what we are seeing today. In this light, the sustainable handling of raw materials is our highest priority. We are developing primary crushing plants that are reaching more outcome by using less material. Our advanced technology is engineered to handle the most difficult applications in the aggregates industry. We understand the importance of machine reliability and design each piece of equipment to thrive in extreme conditions.

    Eccentric Inclined Screen

    The revolutionary Niagara F-Class vibrating screen features new technology that offers simplified maintenance combined with maximum performance and longevity. The new design retains the technical benefits the original F-Class is known for, such as improving performance in material stratification and reducing blinding and pegging.


    Eccentric Inclined Screen

    The Niagara N-Class vibrating screen is designed to improve efficiency and reliability in heavy-duty applications. It is built with an advanced four-bearing design that minimizes structural vibration and maintains constant g-force and can optimize crushing plants and screening operations through its ability to screen up to 5,000 tonnes per hour.



    The Niagara L-Class vibrating screen is a versatile and easy to maintain linear machine, with no timing belts or gears that need replacing. The system has proven its worth wherever smooth screening with the highest degree of separation is to be achieved. The machine is a functional, robust and economical solution for dry and wet screening.

    Your Benefits are ensured

    • Improved Product quality
    • Increased product output
    • Reduced CO2 emmissions

    The Process

    The process chamber of a pelletizing disc forms a horizontally inclined, rotating, flatcylindrical vessel. The fine concentrates are agglomerated with use of sprayed water into green balls with 9 to 16 mm.

    These balls roll

    These balls roll off a discharge chute and onto a belt conveyor that leads to a roller screen. The roller screen classifies the pellets into oversize, undersize and correct-sized grains.

    Live Material Analyse

    The pelletizing discs THE SCARABAEUS® 7500 pelletizing discs are equiped with advanced camara systems that provide you with live time analyse of your material.
