New improved drymix plant offers NZ hi-tech products - Tenders Gazette

Concerned that New Zealand is ‘twenty-five years behind Europe’ in the availability of drymix cement-based products, a New Zealand businessman has invested heavily in a new plant incorporating the latest European equipment to provide the New Zealand market with a wide range of precisely formulated drymix products.

Geoffrey Clark says his new company Cemix Drimix is building a fully automated plant in Onehunga/Penrose which will have the capacity to produce between 15 to 20 tonnes of finished bagged products per hour to 48,000 tonnes per annum on one shift.

One of the salient features of this plant is that it handles dry powder material without using screw conveyors or air slides. Instead, it incorporates the patented fluidisation technology from Raute Precision Oy from Finland which makes powders (sand and cement) flow like liquid, enabling the use of double flap butterfly valves for accurate and high speed dosing.

The whole plant is computer-controlled for accuracy and consistency of finished products and fully automated, requiring only four people to operate it. Yet it has the unparalleled capability to produce products with up to 17 different ingredients.

Project manager Bhav Dhillon comments that, until now, there has been very little control over what happens on a New Zealand building site. “Concrete blocks are made to fairly rigid specifications, yet builders mix concrete and mortar are dumped on site with shovels.”

He says that future legislation will tighten up on these unsafe procedures and Cemix’s new plant will offer consistency and low cost products, enhanced product performance and a wider range of products, although they will initially supply dry concrete, quicksetting concrete, mortar mix and mason mix.
