Gypsum mining - more coarse grain, less fines

Two 550-13 sizers were delivered under the condition of producing a coarse grain with the lowest possible proportion of fines. Our sizers are to be used for the first time in the production of coarse grains in raw gypsum. The special feature of the application is the high compressive strength of up to 250 MPa that our sizer can process. This makes it possible for the customer to achieve this efficient process for the first time.


The two crushers are used in the secondary crushing of raw gypsum.


Compressive strength: 250MPa

Feed grain size: 0-300mm

Final grain size: <70mm with avoidance of fractions <20mm

Throughput: 150t/h


The drive technology and tool geometry developed in-house ensure outstanding results in terms of the quality of the final grain size and make our sizer the perfect choice for use in limestone and gypsum rock.
