Cement mill shell modification (inlet section) we are intending to replace parts of old fls ball mill body due to old cracks on inlet section and even part of shell welded repeatedly in recent years: trunnion shaft (mat. gs 2o mn5) of cast steel (mat. gs 20 mn5).
Cylindrical mill shell, which under high pressure is able to grind raw materials, clinker, slag and other materials with a no replacement has been necessary of the original cast steel linings, which are believes it is better to rely on two cement mills to take into consideration a certain degree of redundancy.
Design of cement mill liners there are several types of cement mill liners: feedendliners, liftingliners, classifying all have some features in common. magotteaux determines the optimum design and alloy for cement mill liners to give the best mill protection. this is done according to a variety of factors such as shell liner type, rotation speed, maximum ball diameter, grinding.
Especially, the company has designed a new type of single drive tube cement mill which is shellsupported and mounted on the new type of double slide shoe bearings, which feature great lubrication, light weight, easy replacement and maintenance, etc.
Turkey: korfez eng. has signed an order with a cement producer to supply a new shell lining system. the scope of the order is a complete replacement of a wear shell lining for a singlecompartment mill with an effective grinding length of 4m and 14.5m, the mill discharge and complete new manhole covers in modified execution.
It protects the shell while ensuring optimum lifting of the mill charge. in the second compartment (and also in our onecompartment cement mills) we use a corrugated lining designed to obtain the maximum power absorption and grinding efficiency. for special applications, we can supply a classifying shell lining for fine grinding in the mill.
