Hazemag delivers ultra mobile crushing and screening unit

Hazemag has always focused on building a crushing and screening range for modern times. The latest Dynarox range presents its latest forward-thinking innovation.

Hazemag has a unique history within the quarrying and aggregate recycling sector, which started in the embers of wartime Germany.

The German company, registered by Dr Ehrhardt Andreas and Richard Rendemann in 1946, began in the crushing sector following World War II.

Hazemag’s original impact crusher, the Andreas-type impact crusher, was used to help process a large amount of building rubble left in the wake of German cities destroyed by the war.

The crusher proved successful as Germany rebuilt itself in the following months and years, and Hazemag’s enduring success has lived on close to eight decades later.

The German original equipment manufacturer, a European household name, has consistently built mobile crushing equipment to suit modern needs.

Hazemag and allmineral managing director of Australia Teddy Craies and project and service engineer Jaco Botha spoke to Quarry about how this concept has helped redefine their new Dynarox range of mobile crushers.

Hazemag’s designers and engineers went into the industry to better understand their customer’s pain points regarding crushing and screening equipment. There were three resounding responses: It needed to help their sustainability goals, be mobile, and help improve aggregate quality.

Craies and Botha believe Hazemag’s new Dynarox range will impress Australian customers on all three fronts.

“We’re excited to see how it will perform and how our customers will receive it,” Botha said.

“And especially to see it in Australia, we think it offers some real advantages to quarry operators here.”

Hazemag understood many of its customers and potential customers in Australia and abroad were operating across multiple sites.

As operations expanded to cover different sites and sometimes various aggregates, they wanted a machine to go with them wherever needed.

In the past, this has been a drawn-out process. The crushing and screening unit needed to be dismantled and moved onto a truck via crane, which soaked up valuable time from the operator’s standpoint.

Hazemag completely redesigned its Dynarox crushing and screening unit to be highly transportable from site to site.

The Dynarox I-120 mobile crushers’ feeding unit, which features a 5m³ hopper, has its hydraulics foldable into a compact, travel-ready design. The outfeed conveyor and the vibrating screen can fold down and towards the machine, as can the front conveyor.

The hydraulics can be controlled by an operator with the ease of a flick of a switch.

The movability of these features enables the machine to be easily moved for transport around a site or to a site further away.

Botha said if the right conditions were in play, the machine could take around 30 minutes to fold down and be ready for transportation.

“It used to take a lot longer because you had to dismantle and set up in a very intensive way and sometimes required a crane,” Craies said.

“It was hard to get away from that because the mobile crusher, traditionally, has been a bulky piece of equipment, but we’ve redefined that with this compact, lightweight model.

“This machine is much more efficient; it improves the movability in the pit and on-site, and it also improves the movability on the road due to the compact design.”

The light and compact machine can also improve fuel burn. The lessened weight compared to other units on the market allows for reduced towing load when transporting, which helps reduce quarries’ impact on the environment. The mobile crusher also features a diesel-electric direct drive, which extends fuel efficacy and allows lower emission levels.

Yet, Hazemag’s new range of mobile crushers is far from just lightweight crushers in a portable package. Hazemag has packed it with customisable options to ensure clients can alter the equipment to suit the needs of their operation and aggregate.

The pre-screen conveyor and post-screening unit, available as a single or double deck, are optional to suit the needs of the quarry.

The double deck pre-screen allows for efficient fines screening. It contains an integrated bypass flap to transfer the fines to the pre-screen or the final product.

“This came about from our experience on the market, which we saw needed a compact and customisable solution that is easy to move around,” Craies said.

“Many operators we spoke to are also moving towards the green economy, and we needed to build a machine that is more in tune with how customers are changing their footprint.

“While there is a standard model, we can work with the customer to customise it to suit their needs and how they operate best.”

Hazemag has added a wind sifter and an optional magnetic separator to the Dynarox I-120 model.

The optional separator efficiently extracts steel from the aggregate mix while the wind sifter shifts lightweight materials such as wood, plastic, and paper from the mix.

This results in quarries being able to produce aggregate with assurance about the quality of its gradings being up to specification and regulations.

“The combination of these features will reduce the amount of contamination in your product and improve the quality,” Craies said.


Few original equipment manufacturers can match Hazemag’s history within the industry.

Customers who invest in Hazemag’s Dynarox mobile crushers can the benefit of the company’s Australian-based staff, like Botha and Craies, as well as its renowned engineers in Germany.

Hazemag’s German engineers also get flown to Australia to train new customers to get the best out of their new equipment.

The company has extensive stock for all its machines in the Canning Vale warehouse, located in Western Australia.

Craies said Hazemag has invested heavily in upskilling its staff on the new Dynarox equipment and remote access capabilities.

“We’ve invested heavily in this area to help customers manage their equipment, do predictive maintenance and HazConnect, which customers can track how their machine performs via their mobile phone,” he said.

While its first-ever crusher was built to suit the era’s needs, in the new Dynarox range, Hazemag has delivered a mobile crusher to suit the needs of modern quarrying.

“There are many years of experience and development that has gone into developing what we have today,” Craies said.

“We’ve designed this technology to help get quarries to be able to move, and we’re excited to bring this to the market.” •
