Unique evolution over the centuries

The iron-smelting works has turned into a technology leader

Our company – The story began in 1607

BHS-Sonthofen has been around for more than 400 years. Our history is unique – what started in 1607 in the diocesan iron-smelting works in Sonthofen has been shaped into a leading technology company over the centuries. 

Milestones

1607

The company’s history began more than 400 years ago, when an iron smelting facility was built at the present headquarters. Back then, the works produced wrought iron from iron ore mined in the region.

1859

The iron smelting industry in this region was discontinued, thus ending operation of the Sonthofen Royal Bavarian Smelting Works’ furnaces. The site adapted by focusing on the production of a wide range of machinery, equipment and foundry products.

The first twin-shaft mixer for concrete production is shipped from the factory. What began small – with an initial mixing trough filling of 0.15 m³ – is constantly being developed further due to the high demand for concrete. Today, the largest twin-shaft batch mixer holds up to 9 m³ of hardened concrete per batch and is known worldwide as the ‘original product’ among concrete mixers. For major international projects, it is considered an international industry benchmark. In 2019, the company delivered the largest twin-shaft mixer in the corporate history to date with a filling volume of 28,000 liters. 

1912

The first jaw crusher was built and used at local construction sites. The advantages of mechanical assistance at major construction sites became quickly apparent, prompting BHS to develop further shredding machines over the coming decades. This was the origin of today’s range of shredding machines.  

1927

In the wake of WWI, “Hüttenamt Sonthofen” became part of “Bayerische Berg-, Hütten- und Salzwerke AG” together with other Bavarian state-run enterprises. During this change, it was renamed “BHS-Hüttenwerk Sonthofen.”

1953

BHS developed the first rotary pressure filter. Based on this, BHS engineers started to develop different filter types for the efficient separation of solids from liquids. This lay the foundation for today’s Filtration Technology division.

1996

In the early 1990s, the State of Bavaria sold its shares in “Bayerische Berg-, Hütten- und Salzwerke AG.” This resulted in the BHS plant Sonthofen becoming the legally independent company “BHS-Sonthofen GmbH.” Management, under the leadership of Dr. Christof Kemmann, took over all the company shares.

1997

Upon special request, BHS delivered the first rotor impact mill for an application in the recycling industry – the customer was more than just satisfied. This marked the beginning of the Recycling Technology division.

 

2015

Starting in the 1990s, BHS has been doing business on an international scale. Initially, the company mainly operated in German-speaking countries. At the end of the 20th century, BHS expanded across the globe. Starting in Europe, BHS then established self-owned subsidiaries in North America (1998), China (2001), India (2007) and finally Australia (2015).

2018

BHS acquired AVA GmbH & Co. KG, a leading process technology company based in Herrsching am Ammersee (Germany), to strengthen its market position in the field of mixing technology. This move furthermore supplements the company’s competence in the field of solid-liquid separation with AVA’s drying technology.
