Bredenbeck lime works
The lime works in Bredenbeck is a listed ensemble in the municipality of Wennigsen (Deister) . The disused factory is located on Frauenweg in Deister .
history
The factory employed up to 250 workers around 1900. There were three specially built rail connections. A narrow-gauge railway from the limestone quarries in Deister, a horse-drawn tram from the nearby coal mine "Gute Hoffnung" and the standard-gauge railway line Weetzen – Bredenbecker Kalkwerke, which went into operation in 1890 . In 1924 production was discontinued, the railway line was shut down and the chimneys were blown up in 1925.
Lime kiln
Initially, two ovens were used for lime burning . The chimneys were comparatively low and square. Around 1910 new types of ring kilns were in operation, the chimneys of which were 110 and 90 meters high. The larger of the two ovens was "three-leaf". This means that all three individual processes of lime burning - running in (setting), burning and clearing - could run in parallel. The kilns were worked in chord . The shift started at 6 a.m. and ended at 6 p.m. To avoid getting burned, the workers placed wet bags over their heads and torsos. Gewecke gives the earnings at 6 Reichsmarks per hour. The kiln could not be fed with coal from the Deister alone , as the calorific value was too low. Therefore, coal supplied from Westphalia was used as an additional energy source.
raw material
In the Bredenbeck area there are natural occurrences of Serpel limestone with 98% lime and only 2% sand. It is a natural stone that represents a unique local special development of the Upper Jura in the Münder Mergel . The fossil rock is fossilized tubes of tube worms. The benches are located in the Lehmbrink and Speckenbrink sections up to the Deisterkamm on the border with Springe.
