The landmark acquisition that strengthens Weir Minerals Europe’s comminution offering

Sebastian Rakoczy of Weir Minerals Europe explains how the company’s recent acquisition of Trio Engineered Products has underlined its status as a full-service equipment supplier to the mining industry.

Weir Minerals has made its name as the leading supplier of slurry handling equipment - our Warman® brand is a world leader in the centrifugal pump market.

At the end of 2014, we acquired Trio Engineered Products, a manufacturer of crushing and separation equipment with a well-established reputation in some of the world’s largest mining markets such as North America and China.

For our product portfolio, the acquisition has been enriching and transformative. The Trio® product range complements our existing comminution product portfolio under the Enduron® brand. As a result, we can now offer a complete set-up of highly engineered equipment that fulfils the crushing and grinding challenges of the world’s biggest mining operations.

High-volume comminution
The first product in the comminution process is the feeder. These machines are capable of accepting large surges of run-of-mine feed coming from site haul trucks. The Trio® TF series of grizzly feeders range in size up to 1.8m wide by 7.3m long, and are available in either single or double-decked configurations. Nominal capacities of up to 770m³ per hour are possible.

The acquisition has now increased our capabilities in the mining-focused primary crushing applications. With our Trio® CT series jaw crushers, the maximum available feed opening sizes are 1.5m by 2m, and capacity ratings up to 1,600 metric tonnes per hour depending on the bulk density and the feed size distribution.

Another option for primary crushing is the horizontal impact crusher. The Trio® APP series impact crushers offer high reduction ratios for feed materials with particle sizes up to 1.2m and capacities up to 1,000 metric tonnes per hour depending on the material. With rotors either cast in solid steel or fabricated in an advanced stress-relief design, these crushers are of heavy-duty design to suit the different applications and requirements to the process.

For secondary and tertiary crushing applications, Weir Minerals can now offer Trio® TC series cone crushers that feature large cone head diameters. This allows them to operate at medium speeds while still delivering high levels of output. The largest member of the Trio® TC Series range has a 2.1m head diameter, weighs 88 metric tonnes and can crush up to 2,100 metric tonnes of material per hour as a secondary cone crusher.

Our new and advanced Trio® TP series cone crushers have been developed to address the market need for heavy-duty, high-production cone crushers for construction aggregates. These high-performance units allow for maximum inter-particle breakage, which provides more cubical products for use in concrete and asphalt production. These machines provide increased application flexibility.

As well as the crusher types mentioned above, under our Trio® crusher range we also offer high-speed vertical impact crushers. These machines are perfect for cubical shaped products of small sizes. They are designed to handle the production of fine industrial mineral powders and pre-grinding of ores. In some applications, they also can be an alternative to mills in the further processing circuit.

In addition to our crushing and grinding range, our Trio® portfolio also includes separation equipment. The range of inclined, horizontal and banana screens we offer, together with our existing Enduron® portfolio, enables us to provide solutions for the world’s highest-output mining operations.

The focus is on robust and long-life construction. Therefore, all Trio® screens are of huck-bolted design, using plasma-cut and CNC-drilled side plates rather than welding to avoid the risk of stress fracturing under the pressure of high-speed vibration.

Weir Minerals’ range of screening equipment is completed by our Enduron® dewatering screens, which are in operation world-wide.

Further Process Equipment
With the acquisition of Trio, Weir Minerals can now offer different sizes of permanent and electro-magnets to separate ferrous metal from the conveyors to protect the further process and equipment from damages.

Where high surge bin loads are a factor, Trio® TAF series apron feeders complete the range and are available up to 2.8m width.

Different types of washers can be offered under our Trio® range to efficiently clean the material from adhering clay or other dirt. This prevents the following screens from getting plugged and ensures their high performance.

Cost base
Our Trio® equipment is proven to be up to the challenge presented by the severe conditions of mine sites all over the world, and is of heavy duty design and construction. Our global engineering teams work closely with our Design Centre of Origin (DCO) and two manufacturing facilities in Shanghai.

The Weir promise in a new market
The integration of the Trio® range of products into the Weir Minerals portfolio represents a step-change in our offer to the mining industry. From end-to-end, we are now able to offer complete turnkey packages for processing a large range of mined materials to almost any desired product specification.

Our overriding ethos as a supplier is to help our customers achieve maximum efficiency and the lowest cost of ownership from our equipment. With the roll out of our Trio® range of products across our network, we are now able to expand this philosophy into the mining comminution market, and we are excited about the efficiency gains we can deliver to our customers as a result.
