For solving the problems of the technologies described above, the technical solution of the utility model is: vertical grinding machine, comprise the cylindrical shell and the end cap that are fixedly installed togather, and be filled with abrasive media in the described cylindrical shell, described end cap is provided with discharging opening; By the main shaft that power set drive, described main shaft rotates and is installed in the described cylindrical shell; Classifying turbine, described classifying turbine are set on the described main shaft and close described end cap; Multilayer sanding disc, described sanding disc are fixedly installed on the described main shaft; Be provided with slurry outer circulation loop between described discharging opening and the described cylindrical shell; Described slurry outer circulation loop is provided with the slurry bucket of at least two parallel connections, and the upstream and downstream of described each slurry bucket is respectively equipped with valve, is used to control described each slurry bucket and participates in circuit cycle separately.
As a kind of improvement, described discharging opening place is provided with mozzle, and described shrouding ring is around described main shaft and be fixedly installed on the described end cap, and the space between described mozzle and the main shaft forms tapping channel, and described mozzle peripheral ring is arranged with filter screen.
As a kind of improvement, described sanding disc is provided with some through holes, the through hole interlaced arrangement on the adjacent sanding disc.
As a kind of improvement, described vertical grinding machine also comprises the abrasive media adding set, and described adding set is fixedly installed on the described end cap, and described adding set comprises casing drum and the intermediate cylinder that connects by pipeline; First valve, described first valve is installed between described casing drum and the intermediate cylinder; Second valve, described second valve is installed between described intermediate cylinder and the described end cap.
Owing to adopted technique scheme, the beneficial effects of the utility model are: because circulation cooling circuit is provided with at least two slurry buckets outside, make slurry in process of lapping, the slurry that has ground is pressed in the slurry bucket by kinetic pump, the slurry that grinds does not continue to grind in cylindrical shell, if the silicon carbide micro-powder granularity in the slurry bucket does not reach requirement, then is pumped into by kinetic pump and continues in the sand mill cylindrical shell to grind, qualified then collection has improved the production efficiency of sand mill greatly.
Because vertical grinding machine has adopted classifying turbine, classifying turbine drives down rotation at a high speed by main shaft, under the action of the centrifugal, the bulky grain abrasive media and not grinding material be thrown out of, silicon carbide micro-powder is discharged in the slurry bucket by mozzle, while realized grinding in process of production classification, cycle operation, reduce the manpower milling time, improved production efficiency.
Because sanding disc is provided with some through holes, the through hole interlaced arrangement on the adjacent sanding disc, it is more abundant to make that silicon-carbide particle grinds in the cylindrical shell of sand mill, has improved production efficiency.
Because vertical grinding machine also is provided with the abrasive media adding set, in process of lapping, be provided with according to electric current and add medium in the production process, replenish the quantity of abrasive media, make product stability improve.
