13/11/2017: MilIsidoro Onos' Roller Mill at Sant Martí de Provençals, Barcelona (Turner’s System)

by Mildred Cookson, The Mills Archive, UK

In 1895 Barcelona, besides being the leading mercantile centre of Spain, was also the principal milling centre

The suburb of Sant Martí de Provençals featured many substantial mills, not the least striking of which was the "handsome building" erected to Turners’ design, for Isidoro Onos.

Described in detail in the June 3, 1895 issue of The Miller, the complete roller plant had a design capacity of 30,000 kilos per diem.

The mill building proper was a substantial three-storey erection, 22 and a half metres long by five metres wide, with an engine house, five metres wide by 13 metres long, added to one end, with a boiler house adjoining.

The building was built with ample expansion room should trade justify such a course. The wheat-cleaning department at the opposite end of the mill was five metres wide by 13 metres long and divided from the mill by a party wall.

Occupying three floors, it held two bins, each having a capacity of 1,100 bushels, to which the dirty wheat was elevated on entering the building.

From these bins the wheat passed by means of an elevator to a Zigzag separator on the top floor, after which it was treated on a machine for removing stones, and then passed to a system of cockle and barley cylinders, specially arranged for taking out the numerous seeds found in Spanish wheats.

The grading to the cylinders was accomplished by one of Turner’s patent Vibromotor sieves, whose action was found to be effective for grading the wheat.

From the cylinders, which were on the second floor, the wheat fell to a Eureka smutter, and was then elevated to a Eureka brush machine. These two machines were placed on a platform on the ground floor in order to avoid sinking the elevator bottoms below the floor level.

The Zigzag, smutter, and brush machine were each connected to Turner’s patent Whirl dust collectors. In the mill itself two bins received the clean wheat elevated from the brush machine in the wheat-cleaning department; each bin had a capacity of 600 bushels.
