This combined milling machine, made in the early 1900's, has the name "Henry Bamford & Sons", a forerunner of JCB, cast into the supporting frame. It was designed to produce animal feedstock, either by crushing between a pair of adjustable rollers or by coarse grinding, or 'kibbling', using a pair of conical grooved steel plates, one fixed, the other rotating. The gap between the plates is adjusted depending on the material being milled and  the quality of the product being produced to be suitable for a range of animals and purposes. After the required product had been transferred
into sacks, a label indicating the contents would be attached to the tie around the neck of the sack.

The machine is driven by the Diesel Engine through a series of shafts, pulleys and belts. Farmers sometimes use similar machines for producing animal feed, driving them with a belt from a tractor or a stationary engine.
