Hammer mills are particularly suited for grinding soft to medium-hard products such as grains, herbs, spices, protein-rich ingredients, nutrients, premixes, and minerals. Dinnissen’s new range of multitasking hammer mills enables the user to screen output particles ranging in size from 3 mm down to 150 microns.

Single hammers or double hammers are used depending upon the specific ingredients to be grinded down. A crucial feature of the new product range is the enormous range of screening panels, surfaces and perforations available, as these features determine the capacity, quality and effectiveness of the screening process and make it possible for Dinnissen to offer its clients an effective solution for practically any grinding and/or screening challenge.

Two rather striking members of the new product range are the small Easy-to-Clean Dinnox Mill and the Dinnissen D-Topline Hamex Hammer mill with automatic screen changer.

From the small Easy-to-Clean Dinnox Mill …

The Easy-to-Clean Dinnox Mill is a very compact hammer mill with a minimum capacity of 30 kg per hour. The small Easy-to-Clean Dinnox Mill is fitted with exchangeable grinding rotors, providing it with a variety of breaking, cutting, and grinding functionalities, as well as exchangeable screening panels and adjustable RPMs. This allows the user to easily and quickly switch between an almost endless variety of grinding and screening applications, depending upon the specific ingredients process and the desired end result.

In spite of its very compact design, the new Easy-to-Clean Dinnox Mill is also fitted with completely detachable grinding rotors and extra-large inspection hatches, making it easy to access all the components, including the screening panels, and to clean everything quickly and thoroughly. The Easy-to-Clean Dinnox Mill is available in stainless steel 304, RVS 316L, and polished or electrolytically polished RVS. It can also be fitted with an automatic cleaning system based on compressed air, CIP, or hot steam/air for extra hygienic applications, and complies with all EHEDG requirements.

Dinnissen’s largest hammer mill will also be on view at Powtech in Nürnberg. The new D-Topline Hamex Hammer mill with automatic screen changer can handle grinding capacities of up to 45,000 kg per hour, and the screen changer has space for 4 to 6 different sets of screening panels. The mechatronic screen changing system automatically selects and places the appropriate set of screening panels in the hammer mill. After the production process has been completed, it also removes and stores the screening panels in less than 40 seconds. This makes it possible to change screens extremely quickly and greatly reduces downtime.

The D-Topline Hamex Hammer mill features a new design which greatly increases the surface area of the grinding and screening panels inside the hammer mill, which in turn provides increased grinding and ringing capacity. The screen storage facility is also fitted with an extra-wide chamber that can be automatically opened. This makes it easier to carry out maintenance and remove damaged screens if necessary, thereby minimizing downtime. The new hammer mill has a maximum speed of 1500 RPM, giving it a longer usable lifetime and in lower energy consumption than its predecessors.
