Among all the mills, the largest and most striking was undoubtedly Franjo Pust's mill. At the beginning of the 19th century, before milling production began, the site housed a factory for the production of snuff tobacco (burmut), which was run by Mirko Markić. In 1831, the factory was taken over by Franjo Pust and his associates, who successfully operated it until 1848.

Following the introduction of Austrian absolutism and the state monopoly on tobacco, the private factory was converted into a roller mill in 1849. Based on the size of its rollers, it is believed to have been the first mill of this technology in Croatia, imported from Vienna by the company L. Nemelka. The mill was powered by an 8-meter-high overshot water wheel, which received water from a large wooden channel (flume) over 200 meters long, directed above the village houses. According to data from old business records, the mill processed up to 25 wagonloads of wheat monthly.

In 1923, the mill was electrified by installing an alternating current generator powered by a turbine located in a sawmill 450 meters upstream. This electricity supplied the entire upper part of Ivanec.

After 1932, the mill was leased by Emil Obsiger, the son of the former owner of the "Janje" hotel inn in Varaždin. Over time, the mill was often referred to as the Pust-Obsiger Mill. This mill produced very high-quality white wheat flour, known as “nuler” and “cvajer.” The popular name for the facility was “Mašina,” (machine) due to the use of large machines in the production process.

The mill ceased operations in 1970, functioning as a work unit of the company “Bednja-Mlin” from Ludbreg. The management ordered the dismantling of all machinery, which was then transported to Ludbreg. Unfortunately, the building was left to decay and was later demolished down to its foundations.
