Product feature: Metso Lokotrack LT1110

Date: 13.10.2020

MIMICO recently delivered a new Metso Lokotrack LT1110 mobile HSI (horizontal shaft impact) crusher to Ravensdown’s quarry in South Canterbury

The Lokotrack LT1110 mobile crusher is known for high capacity and reduction ratio. It’s a compact track-mounted mobile impact crushing plant, commonly used for the crushing of medium to low abrasion rock, such as limestone, and recycled materials, such as asphalt, concrete, and bricks.

The LT1110 can be used as a standalone unit or in combination with other mobile equipment to obtain a range of calibrated end products. It’s also available with an optional single deck screen module with a return conveyor to produce a calibrated end product.

Garth Taylor, MIMICO’s crushing and screening business manager, says the LT1110 was perfectly suited to Ravensdown’s requirements.

"The LT1110 is compact, productive, durable, and versatile in terms of its crushing output, so works well for Ravensdown," says Garth.

"They needed a primary crusher to produce a variety of products from their limestone feed. The LT1110 offers high reduction ratio and good-quality end products at high production rates.

"It’s also an extremely efficient crusher on several levels. Reduced operating costs derive from the unit’s durable wear parts and components. Ease of maintenance reduces downtime and increases production capacity."

Roger Buckingham, Ravensdown’s quarry manager, says he’s pleased with his company’s new impact crusher.

High Capacity and Reduction

"We needed to upgrade our crusher, as we previously ran an ageing impactor from a brand that was no longer supported globally," explains Roger. "Metso’s equipment has a very good reputation, so with the Metso LT1110 we knew we would get a robust and versatile crusher.

"This is a reliable machine and simple to operate. Quick, easy, and safe maintenance access will increase availability of the plant. Also key for us was having local support in terms of both service and parts supply. Like any operation, we can’t afford a heap of downtime, so having MIMICO handy to help, when needed, is a big plus."

The LT1110 will be used by Ravensdown for primary crushing of limestone in pit prior to secondary crushing. They produce Aglime, which is ground limestone used to improve soil health, along with face and track rock. Face rock is used in landscaping applications, while track rock is used on farm tracks and races.

About the Lokotrack LT1110

The Metso LT1110 mobile HSI crusher is built around Nordberg NP1110M HSI crushing unit.

The Metso HSI crusher consists of heavy rotor, wear-resistant materials, and an optimal crusher chamber design, which has proven revolutionary in improving capacity and product quality, as well as in reducing operating and wear costs, the manufacturer says.

The NP1110M has a unique triple wedge blow bar attachment system. With the blow bar securely aligned into the backing beam of the rotor, the attachment system reduces risks of breakage and enables pushing the use of chrome iron blow bars beyond conventional limits.

The high inertia rotor, in turn, improves crushing reduction and provides stability in the process, reducing energy consumption and increasing long-term performance.
The Metso IC process control system optimises crushing results. It enables single-button start and stop and features in-built troubleshooting as well as various parameter selections.

The Metso LT1110 is also fitted with Metso’s optional ICr remote monitor and controller. The ICr allows the excavator operator to remotely control and monitor the crusher from the excavator cab. The controller utilises a Bluetooth connection between the excavator and crusher to allow transfer of information and adjustment of vital crusher and feeder parameters.
