Implementing the delivered classifying screens T-Class 2100×5000 2D HT T-Class with conveying system our customer was able to reach the capacity of 600 tph. The vibrating effectively handle even the largest diabase pieces with a size of 200x500x500 and cut sizes 20-100 mm. The installation of the perforated plate rubber screen media also provides full clearance from the top to the bottom of the screen with minimal risk of material blinding.

There are no unsolvable tasks for our processing technology. In this project, we supplied the Niagara T Class 180 2100×6000 1D for basalt processing. By using it in his operation, our customer has the ability to screen the material in cut sizes of 63 mm and achieve a capacity of 570 t/h. Even the largest pieces, measuring 90 x 90 x 90 mm, are successfully processed thanks to the innovative Niagara T-Class two-bearing vibrating screen, which offers a high degree of versatility. The concentric shaft arrangement of the vibrating screen features a range of speed and stroke combinations to handle a variety of loads and tonnages. By including the in-house manufactured Niagara Ty-Deck polyethane panels, featuring opencast and permanent curing after hardening, we provided our customer with the chemical properties required for wear resistance, further strengthened by the use of the Niagara Snap-Guard® system.

Efficiency enhancing support for our customers in their processing endeavors – our mission. Our customer processes basalt in Germany. As a building material basalt is as old as mankind itself. What has changed over the millennia is the technology of how basalt is mined and processed. As the responsible handling of natural resources is the top priority for our customer, he was looking for an innovation: a resource-saving and profit-oriented solution that have to replace his old technology. We offered him our eccentric driven N-Class DSS 1400 x 3500 with reduced loads and energy requirements. He trusted us and now he is able to process up to 400 tph, successfully handle the largest basalt pieces measuring 950x950x700 mm, and increase his efficiency, capacity, and quality – all with an awareness of our environment.

We have collaborated on extensive projects with one of the largest manufacturers in the world to improve the performance of railroad ballast processing. In this case, we successfully supplied six of our eccentric drive F-Classes of the type D1930x5260_5000 for processing of rail ballast at 900 TPH with cut sizes 22 – 63 mm. The vibrating screens are equipped with the innovative Flex-Mat screen technology that allows to vibrate independently from hook to hook for faster material stratification.. Covering of the screen surface with the special Flex Mat screen media is the best solution to increase plant uptime, screening performance and productivity. Sounds interesting?

What would you do at an altitude of 2200 meters above sea level in Alps? Skiing? Wouldn’t be a bad idea, but the great Niagara team is building the highest altitude machine in Europe there! A dam is being built in the Tyrolean Alps and we are thus involved in one of the major dam construction sites in Europe that intends to focus on green energy and sustainability in the long term. Our innovative N-Class S 1600 x 4600/3000 2D was installed there and is able to smoothly running even under the severe winter conditions in the Alps. The one-and-only eccentric drive technology makes possible to screen up to 550 tons of granite pro hour at cut-sizes of 32mm. We delivered the vibrating machine with in-house produced Niagara lubrication and screen media. Do you also have such advanced projects in mind? Share them with us – we will best advice you how to put them into live!

There is another Niagara project on the right track for success: We successfully supported a customer of us facing problems with his screening performance to improve his screening results by implementing our single deck NIAGARA F-CLASS S 1600×5000 1D vibrating screen with eccentric drive in his basalt processing operation. The innovative Niagara eccentric technology enables him to process more than 400 tons of very abrasive basalt per hour and all while using the perforated plate screen media to easily deal with the largest pieces of 500 mm in diameter. Do you also want to achieve such results? Contact us now!

Can eccentric technology improve screening capacity? The Niagara N-Class is proving it. The machine pictured is headed to a mineral processing operation that screens a variety of large materials, from granodiorite and porphyry to diorite and andesite.
Thanks to the N-Class 2000 x 6000 1 D’s innovative eccentric design, it can reach capacities of more than 2,150 tph with cut sizes up to 300 mm. The eccentric screening action optimizes the machine for heavy-duty applications such as classifying and scalping. The eccentric shaft forces the screen body to follow the shaft movement. While it travels upward, the counterbalance weights move in the opposite direction, creating an equal force to that generated by the screen body. These two opposing forces cancel each other out while maintaining a consistent positive stroke that minimizes structural vibration and handles material volume spikes without losing momentum. Additionally, the N-Class transmits fewer vibrations to the structure, maximizing component wear life.

The scope of supply of the primary crushing plant included Niagara push feeder and the eccentric heavy-duty screen of type N-Class. The overall planning and engineering was carried out by Haver & Boecker Niagara. The project involved the conveying technology, dedusting, steel and solid construction. In the quarry, our customer produces up to 750 tons per hour of the high-quality natural stone product from greywacke – a quartzite sandstone with very high compressive strength.
The largest pieces have a diameter of up to 1200mm and the first cut is made at 150mm, and the second at 32mm. The challenge of the project was the high requirements of the customer in terms of quality, immission and environmental protection, as well as the tight schedule for implementation. An example of the flexible production is the water building block screening plant, in which the weight classes 5 to 40 kg. and 10 to 60 kg. can be processed individually or simultaneously as required via 2 eccentric heavy-duty screens of the F-Class type.
The sound-insulated building facade, energy-saving electrical components and the dedusting system ensure immission and environmental protection. The implementation period from project start to commissioning took 12 months. The successful implementation of the project was achieved through many years of joint and close cooperation with the teams from Haver & Boecker Niagara and the operator. It is the result of bundling the experience of the specialists from both companies. The detailed implementation of the operator’s specifications is an impressive example of the solution competence of the Haver & Boecker Niagara experts, especially with regard to the efficient design of primary crushing plants and their precise implementation.

In 2016 we developed this amazing gravel and split plant for medium-hard and hard rock in Steinbruch Schelmberg. There we implemented three of our screening machines type T-Class and two Niagara Feeders. They support our customer to classify his pre-crushed material of the secondary crushing stage by specific sizes, to re-crush the coarse excess material to a minimum size and finally to transport the classified material to the heap. A modern, robust built of this installation allows the processing of more than 200 t/h and crushes the feed material up to 90 mm. The processed material satisfies the needs of asphalt and concrete industry. Our customer is impressed with the fluid process of classifying fillers from fines and realizes that he is saving resources, increasing his productivity, and reducing his costs due to our innovative processing technology.

Quarry operation and environmental protection cannot go hand in hand? Let’s rethink this statement by taking a look at our great primary crushing plant for diabase. By using our F-CLASS eccentric vibrating screen and combining it with Niagara push feeder and jaw crusher, our customer achieves a capacity of more than 500 t/h, i.e. 30% more screening capacity with the same machine size. This yields a more efficient utilization of the machine and the screening media. Our technology also takes into account the extensive requirements for human safety and the environment, such as CE machine directives, dust and noise emissions, and energy efficiency. Still think quarry operations and environmental protection don’t belong together?
