ATREX® mixer simplifies Acotec precast wall production

A new crushing mixer utilizes lightweight aggregate up to grade 30

Elematic introduces an innovative crushing mixer to their Acotec non-load-bearing precast partition wall production line.

The new ATREX® continuous crushing mixer, developed by Finnish technology and equipment provider Megatrex, offers a solution for raw material procurement in Acotec wall production.

The mixer enables the use of use of lightweight aggregate up to grade 30 in Acotec panel production. This means that the panel producers do not need to buy specific grades or store several different aggregate grades anymore. The mixer will bring considerable savings and simplify the production process, especially in market areas such as Russia and China, where fine-grained aggregate is not widely available.

Leca, a lightweight expanded clay aggregate used for cement mix, is manufactured worldwide from natural materials. Leca products may vary from country to country, and Leca particles are generally larger than the size needed for the fine-grained cement mix used in Acotec production.

– Thanks to the ATREX® mixer, aggregate can be directly introduced to the Acotec production line. Otherwise it would need screening and crushing before production, explains Elematic Technical Director Lassi Järvinen.

Innovative but proved technology

ATREX® is a new application in the precast industry, but it is a well-proven technology in many other industries that need continuous processes for grinding, mixing, crushing and dispersing. The technology has been developed in Finland since the early 1990s, originally for the forest industry. Since the 2000s, ATREX® has been introduced in other sectors such as the mining and biotech industries.

– This well-tested and proved technology has been utilized to develop the ATREX® unit for Acotec wall panel production. It has many similarities with other applications such as the pigment dispersion technology needed in the continuous slurrying process of the forest industry, says Miika Partanen, Sales Manager at Megatrex.

The collaboration between Elematic and ATREX® developer Megatrex started in 2014 when Elematic’s Acotec production line was under development.

Compared to the conventional batch mixer, the continuous operation of ATREX®, combined with its simultaneous crushing and mixing properties, made it an interesting tool to improve raw material availability in Acotec production.

Acotec – production lines for any investment size

Non-load-bearing Acotec precast partition wall panels have been manufactured around the world on Elematic’s Acotec production lines for almost 30 years.  

The panels have various benefits, including excellent sound insulation, top-rate moisture resistance and an easy installation method. With Acotec panels, construction work proceeds up to six times faster than traditional brickwork and twice as fast as blockwork.

Elematic’s Acotec production line featured three new automation and capacity levels last year. These levels enable Acotec lines to better address the needs in different countries.

The SEMI line, with a production capacity of 80 m2 per hour, is a simple line with practical combined restacker-handler and automated key functions. The PRO line offers a mid-level capacity of 100 m2 per hour with automated functions for all main processes, and the fully-automatic Acotec EDGE offers a top-rate capacity of 120 m2 per hour and needs only two operators to run.
