Separation of the grinding media fillings of two grinding
chambers or retaining the grinding media in the grinding
chamber in the case of discharge diaphragms
Restriction of the maximal grain size of the grinding
material which is transferred from one grinding chamber
into the following one as a function of the slot width
Transport of the grinding material from one grinding
chamber into the following one or from the grinding
chamber into the mill discharge.
Requirements to diaphragms
Ensuring a grinding material level in the grinding chambers
optimal for the grinding process
As large free cross section as possible to ensure a sufficient ventilation in the mills
Utmost stability and safety of the frames and of the fastening systems of the diaphragms
High wear resistance and security against fracture
of the slotted plates and back wall plates
A Intermediate diaphragm B Discharge diaphragm
C Central discharge diaphragm
D Central discharge diaphragm
with separation of the material streams
For more than 50 years, ThyssenKrupp Fördertechnik have been
planning, constructing and supplying diaphragms for tube mills for
any possible application.
On the basis of this experience, for every application, the optimal
materials are selected for the slotted plates.
ThyssenKrupp Fördertechnik are using the following materials:
Slotted rubber plates
Heat-treated slotted plates of rolled steel
Cast slotted plates
Slotted plates of composite materials
Upon request, also diaphragms with mass flow control systems
can be supplied.
