The SJet is a jetmilling system, which has the advantages of drygrinding with superheated steam. It is used for ultrafine grinding of soft to extremely hard materials in a fluidised bed. By using an air classifier, integrated in the mill, the maximum particle size is limited and it is possible to achieve fineness in the submicron range.

The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

Modeling of grinding mill and circuit is and continues to be a challenging theme for many researchers. Grinding models are mainly used in grinding circuit simulators for process optimization [1], design of control strategies [2,3] and for the analysis of the effect of a change of operating conditions (ball size, shape, rotation speed etc.) on the mill efficiency [4,5].

Wet milling, also known as wet grinding, is a process through which particles that are suspended in a liquid slurry are dispersed in that liquid by shearing or crushing. Once the milling process is complete, these particles are ready for use or can be dried and separated for incorporation into additional products.

Generally speaking, the finished product size below 1500 mesh is generally produced by dry grinding process. For product size from 1500 to 2500 mesh can be produced by dry gridning process or wet gridning process. For products from 2500 to 6500 mesh, wet grinding process is usually appropriate for production. Ground calcium carbonate.

Dry grinding mills are wellsuited to metal powder requirements such as homogeneity of the mixture, uniformity of the morphology and relatively narrow particle size distribution. Milling offers a number of advantages over atomization, the other major production method for metal powder. These advantages include:

Dry ball mill is a grinding equipment that uses dry ball milling process to grind materials. Different from the wet ball mill, the dry ball mill does not need to add water when performing the grinding operation, only relying on the impact and crushing effect of the grinding media on the material to grind the material.

Planetary ball mills are used for the pulverization of soft, hard, brittle, and fibrous materials in dry and wet mode. Extremely high centrifugal forces result in very high pulverization energy and therefore short processing times. Planetary ball mills are ideally suited for tasks in research like mechanochemistry (mechanosynthesis, mechanical ...
