The hammers are free to swing on the ends of the cross, or fixed to the central rotor. The rotor is spun at a high speed inside the drum while material is fed into a feed hopper. The material is impacted by the hammer bars and is thereby shredded and expelled through screens in the drum of a selected size. Hammer mill apple shredder for juicing.

The hammer equipment has been kept fully operational. From the hammer mill pond above the mill a hammer mill channel or ditch leads water to the wooden overshot wheel with a diameter of almost four metres. The octagonal driving shaft is made of oak; it has a weight of about 7 tonnes (15,000 lb) and a length of 9.5 metres (31 ft).

Occasionally, the mill is preceded by a hot-air-swept hammer mill which does most of the drying and produces millimetre-sized feed for the mill. Ball mills are rather inefficient, and typically require 10–20 kW·h of electric power to make a tonne of rawmix. The Aerofall mill is sometimes used for pre-grinding large wet feeds.

The first mill on the site was built in 1576, but it was only linked to weapons production from 1601, when the gun foundry was built nearby. It was used to power the Kronborg weapons factory. It then produced weapons until 1870, peaking in the 18th century, when the factory employed 200 men and produced 6000 guns a year.
The hammer stands in close proximity to the dam of Huťský pond. The adjacent drive feeds water through a wooden trough to the water wheels that drive the hammering equipment through the transmission system. [1] Originally the iron-mill had five water wheels, today three are functional. [4] [5] The mill hall dimensions are 32×12 meters.
