Overview
Cummins Milling is a family-owned flour milling and stockfeed business based in Cummins, on the Eyre Peninsula of South Australia. It describes itself as one of the oldest operating flour mills in Australia, having processed wheat for over 80 years. The business was established in 1930 during the Depression by Aubrey Heidenreich, and the current mill building dates from 1934 after the original mill burnt down in 1933. The mill is heritage-listed and is one of only a few original flour mills still operating in rural Australia. The company operates an integrated site where flour milling and stockfeed production are co-located — a configuration it says is unique in Australia. It produces a range of premium cereal flours for commercial bakeries, flour distributors and food retailers, as well as a home baker range, and manufactures stockfeed and pet feed for livestock producers, stockfeed distributors, racehorse trainers, hobby farmers and pet owners. The company states it is the only Australian mill to fortify flour through a batch mixing process, ensuring consistent mixing with no variation between bags. Located in the heart of South Australia's 'grain country', Cummins Milling sources wheat grown on the Eyre Peninsula, selected by the farming family that owns the business. A stockfeed plant was established in the late 1960s to utilise by-products from flour milling, and both the flour mill and stockfeed plant underwent a substantial upgrade in 2008. The company emphasises accessibility, personal service and responsiveness, offering an out-of-hours service and tailoring products to customer requirements. It distributes across all parts of Australia.
History
Cummins Milling was established in 1930 during the Great Depression by Aubrey Heidenreich. The original mill burnt down in 1933, and the existing building was rebuilt in 1934. It was constructed with local freestone for the walls and large timber uprights and beams; much of the timber was recovered from an old graphite mine near Port Lincoln on the Eyre Peninsula. The mill carries a heritage listing and represents a significant link to the past, being one of only a few original flour mills still operating in rural Australia. A stockfeed plant was established in the late 1960s to utilise some of the by-products from the flour milling process. This co-location of flour and stockfeed production on one site is described by the company as unique in Australia, giving both environmental and operational advantages. Following a substantial upgrade in 2008, both the flour mill and the stockfeed plant produce consistently high quality products serving a wide range of markets. The business has remained family-owned and is operated by a farming family that selects quality grains grown on the Eyre Peninsula. The company states it is the only Australian mill to fortify flour through a batch mixing process, so ingredients are thoroughly mixed with no variations between bags. Its location in the heart of the 'grain country' in Cummins provides an ideal central position for sourcing raw materials and delivering to all parts of Australia. The company has developed a versatile, state-of-the-art mill that can tailor production to exact customer requirements, and it serves customers including livestock producers, stockfeed distributors, flour distributors, racehorse trainers, hobby farmers, pet owners, bakeries, food retailers and home bakers.
