Tietjen presents solutions for fine grinding


Tietjen presents its new developments for the compound feed and petfood/aquafeed industry. 

With the large chamber mill FD, Tietjen presents the latest of its hammer mills optimised for fine grinding of petfood. It achieves a very high throughput of over 15 t/h and reaches a high fineness at the same time.  

For the large chamber mill FD, Tietjen has enhanced its proven design. The durable, optimised rotor design is dynamically balanced and now allows, depending on the recipe, a loading of more than 15 t/h with almost the same installation space compared to other large-capacity mills from Tietjen. The new optimised design and the optional enlargement of the impact zone ensure the very high fineness of the ground material with simultaneous high loading. Particle sizes of < 500 µm at a fineness of 99 percent are achieved even for demanding petfood recipes. 

In combination with a metering screw and the new air-gravity separator AGS AD, the efficiency of the grinding system is increased even further. 

Thanks to the separation of foreign particles with the AGS AD and the subsequent automated discharge with a collecting screw, a smooth operation of the system is guaranteed. To make this possible, the separation of magnetic foreign bodies was optimised compared to the AGS. Pneumatically swivelling magnets and flaps clean the bulk material from foreign bodies fully automatically and then channel the foreign bodies into a collecting screw, which discharges the foreign bodies out of the system. 

Thanks to almost identical installation space and flange dimensions, the predecessor AGS can easily be replaced by the new AGS AD.
