CNC Crushers Roadstone is operating three Trio cone crushers and an inclined Trio screen which it bought from Weir Minerals Africa.
The crushers has allowed the company to produce between 1 000 t t and 1 200 t of aggregate a day for road construction in various areas of the North West province.

Carl Crous, owner of CNC Crushers Roadstone, has opted for the Trio TC series of cone crushers, known for their rugged design.
CNC Crushers Roadstone’s TC36SH (short head) weighs 12 000 kg and has a feed opening of between 100 mm and 180 mm, as well as a head diameter of 914 mm. It has a maximum power capacity of 90 kW and has a capacity of between 27 Mtph and 186 Mtph.
Meanwhile, its TC51S (standard head) has a head diameter of 1 295 mm and weighs 22 500 kg. It has a feed opening of between 65 mm and 135 mm, and a maximum power of 200 kW. The unit has a capacity of between 36 Mtph and 255 Mtph.
In terms of the company’s screening requirements, the aggregate producer has opted for a Trio TIO5162 inclined double deck screen.
Weir Minerals’ general manager for Trio® products in Africa and Middle East JD Singleton says Trio TIO Series screens generate their motion via three timed shafts with eccentric counterweights. The combination of three shafts provides an oval strike with adjustable amplitude, speed and operating angle that are determined by application, feed size and gradation. The vibrating unit uses an oil bath lubrication arrangement.

Their plates are made from hot-rolled steel and are plasma cut with computer numerical controlled punched holes. Trio® products are manufactured utilising Huck-bolt construction techniques to ensure structural integrity and eliminate stress fatigue in the screen body.
CNC Crushers Roadstone has maximised the operation of its Trio comminution equipment by entering into an extended service level agreement with Weir Minerals Africa.
The OEM’s technical field service personnel now spend two full days a month at the operations undertaking preventative maintenance on the equipment.
It is not difficult to see why so many aggregate producers are opting for Trio equipment. As Singleton notes, they want predictability and this is exactly what they are receiving from the Trio equipment.
