Is it possible to cement a liner with two cement slurry densities. In our case, we are drilling with a MW of 1.62sg and LOT EMW is 1.67sg. We are drilling in a very narrow window because we had a kick earlier and we cannot reduce MW less then this value. If we use a slurry of 1.90sg of density, we will exceed the fracture gradient.

Classifying-liners are the best form of cement mill liners to adapt the grinding charge to the feed material´s granulometry while keeping a smooth material flow going. They are efficient energy wise because of the constant optimum grinding charge. Magotteaux produces several types of these. Xclass® is easy to handle and has increased safety ...
liners, where the thickness is still sufficient to protect the shell. It is crucial to point out that shell protection is only one function of the mill liner. It also needs to optimise the grinding process. Clinker grain sizes depend on pre-crusher settings but are in some cases still up to 50mm when fed to the ball mill

Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
The ball mill cylinder is a hollow barrel, which is rolled and welded by several steel plates. The two ends of the cylinder are connected to the ball mill trunnion with end covers. As the main part of the ball mill, it has to bear the weight of the lining plate, grinding media, compartment plate, and grinding materials.
Where grinding efficiency meets mill shell protection. The MVL TM, Magotteaux Variable Lift, liner range covers a large bandwith of shell liners for coarse, medium and fine grinding. The liners are energy efficient and ensure a very low grinding media consumption. Your key benefits: Optimum compromise between lifetime and grinding efficiency
Choice of mill lining A mill lining should be optimized to suit each specific mill. Choosing an appropriate type of lining and design in terms of lining material, thickness and profile is vital for optimizing mill throughput and total grinding costs. Choosing the correct liner material and design ensures that the mill itself is well protected.
and head liners. Besides their protective function, liners are also responsible for the energy transfer from the mill to the charge. In the case of the shell liner, the efficiency of the energy transfer is characterized by its lifting ability. This is the ability of the liner to move the charge to a higher position in the mill due to its par-
