Definitions
- the invention relates to a method for operating a grinding plant through which the product and a carrier gas flow, in which an inert gas is used as the carrier gas.
- the invention also relates to a device for carrying out this method.
- Mills working with carrier gases are widely known.
- the carrier gas is swirled in grinding chambers in such a way that the product breaks apart mainly due to mutual collisions.
- Such comminution is much gentler than the comminution brought about by the grinding material coming into contact with stationary or rotating machine parts.
- the present invention has for its object to significantly reduce the inert gas consumption in a method for operating a grinding system of the type mentioned.
- this object is achieved in that the inert gas is circulated.
- the losses of inert gas are limited to amounts of inert gas which leak out through leaks, but which can be kept small.
- the grinding system shown comprises the mill 1, which via the feed funnel 2 the ground material and at 3 the inert gas, e.g. Nitrogen.
- the regrind-inert gas mixture leaves the mill 1 through the outlet 4 and flows through the line 5 to the cyclone separator 6.
- This separator 6 is followed by a further separator 7, which is designed as a filter cyclone.
- the regrind obtained in the separator 6 is transported by means of a screw 8 into a funnel 9, into which the regrind also passes from the filter cyclone 7.
- a cellular wheel sluice 11 serves to empty the funnel 9.
- a branch line is provided parallel to line 15 and includes line sections 17 and 18.
- a dust filter 19, a compressor 21 and a storage tank 22 are arranged one after the other in the line section 17, into which part of the inert gas circulated passes.
- the compressed inert gas in the storage tank 22 can additionally serve to shake off the filter cyclone 7.
- the line 25 with the valve 26 is connected to the line section 18, which leads to the compressed air distributor 27 above the filter cyclone 7.
- the filter bags located in the cyclone 7 are cleaned by pressure pulses. The inert gas used for this is also not lost since it is recycled.
- the oxygen measuring point should ideally be arranged directly in the main circuit. There, however, it is endangered by the dust content of the gas. It is therefore advisable to arrange them in a bypass to line 15, behind a dust filter. In the grinding system shown, it is in line section 17 behind dust filter 19 arranged, which simultaneously protects the compressor 21 from dust. Of course, other locations for the arrangement of the O2 measuring point in the grinding system are also conceivable. For example, it can be connected to line section 18 (see dashed line of measuring cell 32zelle).
