Bauma, the world’s largest construction industry trade show, set records this year with more than 620,000 visitors across 614,000 sq. meters of show floor at the week-long show in Munich, Germany.
The show, which took place April 8-14, featured 3,700 exhibitors from 63 countries, providing depth and diversity for visitors.
A wide array of portable and modular equipment was on display, ranging from crushing and screening equipment to wash plants. In this section, we present several developments that surfaced at the European show.
McLanahan wash plant, cone crusher go modular
McLanahan Corp. introduced a pair of modular, containerized systems at Bauma in the UltraWash wash plant and the UltraCrush cone crusher.
The wash plant
According to McLanahan, the UltraWash is capable of making three aggregate and two sand products while accepting capacities up to 400 tph. It has both a single-process water feed point and a single-effluent discharge point. The modular design offers a compact footprint, the company says.
The UltraWash system includes several features to simplify maintenance and maximize production. The underpan of the sizing screen features a fines forward slide. This steel tray spans the width of the bottom deck of the sizing screen and facilitates the diversion of a proportion of raw fines into the coarse sand processing stream to help balance downstream equipment and optimize plant capacity. It also permits the alteration of the proportions of fine and coarse deck areas above while precluding entry of coarse material into the fines processing stream, McLanahan says.
The UltraWash feed hopper and conveyor can be upgraded to come with tracks for easier conveyor maintenance.
The modular crusher
The UltraCrush modular cone crusher is also containerized, easy to set up and install, and can be transported around a site or to other locations as needed, according to McLanahan.
The modular cone crusher is made with a heavy-duty cast steel base frame and includes replaceable base frame wear liners. It features a rotating bowl for even liner wear, bronze inner and outer eccentric bushings for more load-carrying capability, and a large, unobstructed feed opening. A hydro-pneumatic tramp iron relief system reduces wear on the crusher if uncrushable material enters the crushing chamber.
All McLanahan modular systems are pre-wired and pre-plumbed for rapid on-site deployment or relocation, the company says. Systems are available in a variety of configurations, including double washing and prewashing, and they come with fully-integrated controls with remote operation.
CDE unveils automation, wet processing system
CDE, a manufacturer of wet processing equipment, launched a plant utilizing next-generation technology at Bauma.
According to CDE, its Intelligent Plant puts to use advancements in machine learning and the Internet of Things to monitor and automate processes that were previously manual in orientation. Intelligent Plant can boost productivity by up to 40 percent, CDE says, enabling the plant to make smart decisions in real time.
“We are constantly striving for innovations to help customers maximize output with minimum effort,” says Tom Houston, director of CustomCare at CDE.
“Intelligent Plant has created thinking plants that reduce downtime, maintenance and fixed costs while increasing yield and revenues for plant owners by almost half – and in some cases even more.”
Intelligent Plant uses a series of belt weighers to accurately establish the amount of material entering the plant and determine the ratio between sand, aggregate and silt output. If the plant is running below the optimal utilization where weight and output are unbalanced against set targets – or failing to maximize production capacity – the plant will respond to address the issue in real time by, for example, adjusting feed rates.
New processing plant
In addition, CDE unveiled its Combo all-in-one wet processing plant, bringing a system to the market that encompasses feeding, sizing, sand washing, stockpiling and integrated water management.
According to CDE, the Combo offers a turnkey solution that delivers control of in-spec washed products from a range of feed materials. The plant can be used in the construction, C&D waste recycling, industrial sands, mining and environmental sectors.
Additionally, the Combo offers rapid onsite setup, reduced startup costs, the ability to process both natural sand and crushed rock, lower power consumption, a smaller footprint and accessibility for maintenance, the company adds.
“The Combo is no ordinary machine, but rather a technological response to the challenges faced by materials producers,” says Sean Kerr, COO at CDE. “It has been designed with a focus on transferring greater reliability and efficiency benefits to customers.”
Sand processing plant lessens water use
Kolberg-Pioneer expanded its sand processing plant line at Bauma to include the new 9201 model.
According to the company, the system is designed to dewater and fine-tune sand to a level not typically possible with traditional sand-dewatering equipment, while also using less water.
The custom-built system is available in portable, semi-portable and stationary configurations with various types and quantities of cyclones, pumps and dewatering screen sizes, Kolberg-Pioneer adds.
“The 9201 is a very customizable unit that can be built to fit any application,” says Brett Casanova, product manager at Kolberg-Pioneer. “The plant has many adjustable features like the deck liner and discharge dam and easy-to-replace parts for quick and simple maintenance.”
Metso launches several new developments
Metso introduced a new mobile screen unit – the Lokotrack ST2.3 – at Bauma 2019 to enable new business opportunities in screening.
The product will be commercially available in 2020, according to Metso.
“For businesses thinking of expanding their operations into aggregates production, the first logical step is often screening,” says Jarmo Vuorenpää, product manager of mobile screens at Metso. “They can be already working in earthmoving or agriculture and want to utilize their existing soil property to grow their business.”
The Lokotrack ST2.3 is suitable for a range of applications, from multi-use to fine screening and recycling, Metso says. It has a 5-ft.-wide screen with a matching feeder and conveyor, as well as an aggressive stroke up to 13 mm with 5G acceleration.
The Lokotrack ST2.3 is easy to set up and can be ready to screen in minutes, the company adds. In most cases, it can be moved from one site to another using standard trailers.
MX series expansion
In addition to the screening unit, Metso introduced its latest addition to the MX multi-action cone crusher series at Bauma.
The MX3 enables improved crusher productivity and lower operating costs with a design optimized especially for midsized quarrying, Metso says.
“Our customers are constantly looking to improve their operational efficiency and to optimize yield for the most desired product fraction,” says Arto Halonen, Metso’s vice president of crushers, aggregates business area. “With MX multi-action technology, we can help our customers to achieve these targets.”
According to Metso, the MX enables cost-effective and safe operations with a high-reduction ratio, great product shape and consistency.
The multi-action technology enables higher uptime and savings in the operational costs of crushing operations, the company adds.
The MX3 is suitable for secondary, tertiary and quaternary crushing stages. Designed for both hard and soft rock applications, the MX3 will first be available for stationary solutions.
New territory for Metso
Metso also chose Bauma to detail how its product portfolio is expanding.
At Bauma, the company launched a hybrid truck body that combines the benefits of rubber and high structural strength steel, enabling mines and quarries to haul more with less, the company says.
“Hauling is one of the most cost-intensive components of a typical mining or quarrying operation,” says Lars Skoog, vice president of mining wear lining and screening at Metso. “In addition to fuel and labor, there’s plenty of maintenance involved, too. To ensure cost efficiency, a haul truck should carry as much payload as possible on every round.
“At Metso, we set out to tackle this challenge and designed a truck body that requires minimal maintenance while maximizing payload,” Skoog adds. “The result is a lower operating cost per hauled ton.”
According to Metso, its truck body is a lightweight, rubber-lined tray designed for off-highway trucks. The elastic rubber absorbs the energy of every impact, preventing it from reaching the frame and allowing for a lighter-than-usual, high-structural-strength steel frame beneath the rubber.
Thanks to this, the body can absorb maximum shock at the lowest possible weight, Metso says.
Metso has been supplying its rubber lining for haul trucks for several decades.
“Many mines prefer lightweight truck bodies because they enable the carrying of more payload,” Skoog says. “However, the problem with these traditional lightweight bodies is their lack of durability – they often have to be replaced every one or two years, or repaired, which gets expensive.”
The Metso truck body is available globally for all major off-highway truck models used in mining and quarrying. Several lining options ensure application-specific fit, the company adds, even in operations that struggle with problems such as carryback.
