Metso helps Wai Kee Holdings Ltd. produce uniform-quality aggregates cost-efficiently by supplying ten Lokotrack mobile plants

Metso will help Wai Kee Holdings Ltd. produce uniform-quality aggregates cost-efficiently by supplying ten Lokotrack mobile crushing and screening units and four CW series wheeled conveyors to its Lam Tai quarry in Hong Kong. The equipment will enable the company to crush rock in demanding and varying rock conditions.

To reach the required capacity at the quarry, the Metso fleet consists of two trains, each including five Lokotrack units: one Lokotrack LT120 jaw plant, two Lokotrack LT300HP cone plants and two Lokotrack ST4.8 mobile screens; as well as two conveyors. Both trains create the same end products.

"As a customer, we are interested in the end products: their shape, quantity and cost of production are key parameters for us. To achieve the best results, Metso offered us a complete solution - not just machines. Thanks to the process know-how of Metso's experts, the right solution to draw uniform-quality aggregates was found," says Derek Zen, Vice Chairman of Wai Kee Holdings.

The entire compact-layout crushing and screening process is tailored according to the customer's needs to produce aggregates in four size ranges. The Metso Lokotracks will operate for 10-12 hours per day to achieve the planned capacity of 1.5 million tons per year.

A cost-efficient solution

The majority of aggregates will be used in Wai Kee's own concrete batching and asphalt plants for ready-mix. "With good quality and constant cubicity, less cement additive is needed, resulting in real savings. The mobile solution from Metso was a clear choice for us. As an investment, this fleet costs less than a stationary plant, is quicker to install and easier to relocate. In this project, saving time really means a cost savings for us. We wanted a technology partner that could add value to our operations by delivering high-quality results and help us meet demanding timelines. Metso was able to address our concerns and provided a customized solution for us," Derek Zen adds.

Customer closeness leads to good results

According to Jarmo Vuorenpää, Metso's Product Manager for large Lokotracks, the solution was based on close cooperation with the customer and Metso's in-depth process knowledge. "We were able to tailor our solution to meet the customer's precise needs and provided a cost-efficient and environmentally more sustainable solution," he says.

Suhen Agarwal, Metso's VP, CSE Sales and Services, Oceania, concludes: "Our team of experts visited the customer whenever they had a query and were able to provide answers during all stages of the project. This customer closeness as well as understanding how important a quick response and delivery time was for them was central."

The order is included in the second-quarter 2015 orders received by Metso. The value of the order is not disclosed. The deliveries will take place during this autumn.
