Summary of the invention
It is an object of the present invention to provide and a kind of will be dried or the material of non-dry grinds to form the method for abrasive material of very fine for economical and reliable, and optimize the pumped (conveying) medium (fluid) flowing in grinding container.
Additionally, the present invention also aims to create a kind of stirring ball mill, dry or non-dry material can be ground to form by this stirring ball mill the abrasive material of very fine, also can economic and reliable ground mill-drying or the material of non-dry.
Disclose a kind of for running stirring ball mill and for mill-drying or the method for the material of non-dry.Directed fluid in grinding container by the fluid passage being arranged in shaft.This fluid is introduced in the spatial neighborhood of last grinding element, and this last grinding element is connected to the upstream of the exit region of stirring ball mill.In the preferred form of implementation of one, fluid is introduced in stirring ball mill between grinding element and last grinding element.In another kind of form of implementation, fluid sprays into, is blown into or is drawn in grinding container between last grinding element and exit region of stirring ball mill.The parameter run according to stirring ball mill, changes fluid and enters the mode of stirring ball mill.If stirring ball mill such as runs with negative overvoltage (vacuum), then during fluid is inhaled into grinder.
Fluid moves in grinding container with the speed of 0 to 50m/s after entering or injecting.Fluid preferably moves in grinding container with the speed of 0 and 5m/s.How this speed and fluid flow through the free cross section that the mode of grinding container depends in grinding container.Compared with the grinding container with a small amount of component/grinding element, be blown into speed identical in the case of, due to less free cross section, in the grinding container with many component/grinding elements, flowing velocity is higher.Flowing through of being made up of fluid and abrasive material is exported from grinding container by segregation apparatus.It is connected to this segregation apparatus downstream for separating another separation assembly of fluid and abrasive material.
When mill-drying material, it is preferred to use air, noble gas or steam are as fluid.In order to ensure dry grinding, use the overheated steam being dried as fluid.Can be as desired to regulated fluid to the addition in the grinding container of stirring ball mill and/or adds frequency.
Additionally, the invention also discloses a kind of for mill-drying or the stirring ball mill of non-dry material.This stirring ball mill includes grinding container, and this grinding container at least local is filled by abrasive body.This grinding container has for the entrance of material to be ground and the outlet of the abrasive material for having ground.Segregation apparatus is arranged in the exit region of stirring ball mill.Shaft is in central authorities' extension of grinding container, and multiple grinding elements are arranged on this shaft.Fluid passage extends through this shaft, and fluid can be imported in grinding container by this fluid passage.Be arranged on last grinding element before the exit region of stirring ball mill at spatial neighborhood equipped with at least one for the tap of fluid.One in these taps is configured to nozzle.
At least one tap is arranged between grinding element and last grinding element.In another embodiment, at least one tap is arranged between last grinding element and exit region.At least one is connected to this exit region and the segregation apparatus downstream being arranged in this exit region for the separation assembly separating abrasive material and fluid.This at least one separation assembly is wind separator.
