The object of the invention is, provide a kind of, for economical and reliable, dry or non-dry material are ground to form to the method for the abrasive material of very fine, and optimize pumped (conveying) medium (fluid) flowing in grinding container.
Above-mentioned purpose reaches by having the method for the feature of claim 1.Other favourable feature can be drawn by dependent claims.
In addition, the present invention also aims to create a kind of stirring ball mill, by this stirring ball mill, dry or non-dry material can be ground to form to the abrasive material of very fine, also can economical and reliable ground mill-drying or non-dry material.
Above-mentioned purpose is achieved by having the stirring ball mill of the feature of claim 8.Other favourable feature can be drawn by dependent claims.
Disclose a kind of for moving stirring ball mill and for the method for mill-drying or non-dry material.By the fluid passage being arranged in shaft, fluid is incorporated in grinding container.This fluid is introduced near the space of last grinding element, and this last grinding element is connected to the upstream of the exit region of stirring ball mill.In a kind of preferred form of implementation, fluid is introduced in stirring ball mill between grinding element and last grinding element.In another kind of form of implementation, fluid in the end sprays into, is blown into or be drawn in grinding container between grinding element and the exit region of stirring ball mill.According to the parameter of stirring ball mill operation, change the mode that fluid enters stirring ball mill.If stirring ball mill is overvoltage (vacuum) operation to bear for example, fluid is inhaled in grinder.
Fluid moves at grinding container with 0 speed to 50m/s after entering or injecting.Fluid preferably with 0 and the speed of 5m/s in grinding container, move.How the to flow through mode of grinding container of this speed and fluid depends on the free cross section in grinding container.Compare with the grinding container with a small amount of member/grinding element, in the situation that the speed that is blown into is identical, due to less free cross section, in having the grinding container of many member/grinding elements, flowing velocity is higher.Flowing through of consisting of fluid and abrasive material exported from grinding container by separator.Another separation assembly for separating of fluid and abrasive material is connected to this separator downstream.
When mill-drying material, preferably adopt air, inert gas or steam as fluid.In order to ensure dry grinding, adopt overheated dry steam as fluid.Can regulate as required fluid to the addition in the grinding container of stirring ball mill and/or add frequency.
In addition, the invention also discloses a kind of stirring ball mill for mill-drying or non-dry matter.This stirring ball mill comprises grinding container, and this grinding container is at least local is filled by abrasive body.This grinding container has for the entrance of material to be ground with for the outlet of the abrasive material that ground.Separator is arranged in the exit region of stirring ball mill.Shaft extends in the central authorities of grinding container, and a plurality of grinding elements are arranged on this shaft.Fluid passage extends through this shaft, and fluid can import in grinding container by this fluid passage.Last grinding element being arranged on before the exit region of stirring ball mill is equipped with at least one for the tap of fluid near space.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 separation assembly for separating of abrasive material and fluid is connected to this exit region and is arranged on the separator downstream in this exit region.This at least one separation assembly is wind separator.
Accompanying drawing explanation
By accompanying drawing, embodiments of the invention and advantage thereof have at length been set forth below.Each element size in the accompanying drawings is not always equivalent to real size, because some shape simplification, but another shape is in order better to show and to compare and expanded with other element.
