Many sand and gravel processing plant operators struggle with challenges such as lack of efficiency and clogging material. They need quality processing equipment that promises versatility, durability and wear protection. Wear protection in the sand and gravel industry is primarily about three sources of problems: Abrasion, corrosion and caking. The Niagara L-Class Double Shaft 2D Type FL-MD 1500 x 5000 has supported our customer in effectively addressing all of these challenges in his round gravel operation. Now he is able to process more than 250 t/h with cut sizes ranging from 0-45 mm. We do not leave him alone with our products, neither in the selection process nor in the ongoing operation. After an on-site inspection, our team of technical experts is able to support the customer and avoid expensive downtime at any time. Would you also like consultation from our processing experts?

Where construction takes place, material with different compositions need to be excavated. This customer’s non-contaminated clean gravelly excavated material is processed in a separate excavation washing plant in the factory, sorted according to the different sizes and used as concrete gravel for the production of concrete. The customer had an old screen, built in 1961, which needed constant repair work and was looking for spare parts that could no longer be found. Therefore, the customer decided to replace this old machine with a Niagara screen. The company was unable to find any other manufacturer who could build a horizontal screen in the same size as the old machine in one piece. Therefore, the customer decided to buy two Haver & Boecker Niagara screens.
The new screen is divided into two 5-ton elements, each 1.5 by 7 meters – the only one of its kind and size in the world. They are driven by four motors. The new plant is used by the customer for rough screening of 16/32, 32/45 and 45/90 gravel from washing plant. The operation of the new screening plant is started by pressing a button from the semi-automatic system of the plant control.

The Lafarge Presque Isle quarry, located adjacent to Lake Huron in Michigan, is one of nearly 1,600 worldwide production sites under the Lafarge umbrella. As a leading materials producer in the U.S., offering everything from standard construction and asphalt stone to unique high calcium limestone (HCL), the Presque Isle quarry relies on the heart of its operation to ensure uptime remains high: a fleet of 14 Niagara F-Class vibrating screens, which operate on a 24-hours-a-day, five-days-a-week schedule. To say the equipment has been crucial to the company’s success is certainly a strong statement — and one backed by solid numbers. In the last decade, Presque Isle has become the largest producer in Lafarge North America’s family, consistently averaging more than 2,400 tons per hour, and an average annual production of nearly 8 million tons per year. Featuring advanced, double eccentric shaft technology, the F-Class vibrating screen produces a constant, positive stroke that handles material volume spikes without losing momentum. As the eccentric shaft turns, the screen body is forced to follow the shaft movement. While it travels upward, the counterbalance weights move in the opposite direction and create an equal force to that generated by the body. As a result, the forces cancel each other, allowing a dynamically balanced system that transmits virtually no vibrations into the structure, and enables optimum production and reduced CAPEX.

To keep up with the demand of sand and gravel products, the quarry requires top-performing machinery. There are 11 vibrating screens, two crushers and dozens of loaders, trucks and excavators on-site, all of which need to be performing efficiently. There we installed our Niagara T-Class concentric inclined screens. The T-Class machines are highly efficient and durable, which is important to the success of any screening business. This is especially true for this particular operation, which runs year-round and sees the effects that cold weather can have on material and screening equipment. “The T-Class machines are on their third season with us, and we haven’t had a single issue,” Nilson Ostero said. “They allow us 20% more capacity than our old screens, but more importantly they are stronger and more reliable.” Do you also want to improve the performance of your sand and gravel plant?

One Canadian producer operates a unique quarry that it is far deeper than most pits. The producer had been using two portable vibrating screens, but the equipment wasn’t holding up to conditions, causing decreased performance and productivity. Our engineers custom-built a chassis around the 6- by 20-foot, three-deck Niagara F-Class, factoring in the desired tonnage and the material that the operation processes to determine what the machine’s stroke should be. Additionally, we equipped the portable plant with a specially sized jaw crusher on the chassis. The producer also asked that the bottom deck of the vibrating screen be end-tensioned. In the company’s operation, the design results in longer lasting screen media and 30 percent more productivity than side-tensioned machines. The machine included a hydraulic system to lift and position the vibrating screen at the optimal angle. The F-Class utilizes a base frame that attaches to the chassis. When the F-Class portable plant arrived at a quarry, they found the single vibrating screen increased aggregates production by about 25 percent, even as rain came and went.
