Usually, chute is dropped into, the raw material input chute of side chute-type that the raw material that there is the center chute-type that the vertical rotating shaft alignment vertical direction along turntable extends drops into chute and extends obliquely relative to the vertical of turntable for raw material being dropped into raw material on turntable.
The raw material on turntable is supplied to via raw material input chute, rely on the centrifugal force that rotates along with turntable and move to radial outside, thus being pulverized between multiple pulverization roller of being pressed of the acting surface (crushed face) of nipping towards turntable and turntable.
To nip pulverized raw material between pulverization roller and turntable, be discharged to radial outside from turntable by means of the centrifugal force of turntable, thus the raw material (powder) being crushed to desired granularity (particle diameter) is graded, and is recovered.In this classification operation, utilize import the inside of mill shell via hot-air channel and the blast of the gas blown afloat (hot blast), with the separator of inner upper being configured at mill shell.
But, in vertical roller mill by the raw material of pulverization process, that wet feed materials as many in water content slag (slag) is attached to the tack of surrounding structure thing etc. is high, therefore need prevent the raw material attachment when raw material drops into and be stranded in the inner surface that raw material drops into chute.Therefore, in the vertical roller mill of the pulverization process for wet feed materials such as slags, mostly adopt and vertically configure the center chute mode that raw material drops into chute.
On the other hand, the dry raw materials such as slag (clinker) are hardly containing moisture, thus the tack being attached to surrounding structure thing etc. is low, therefore there is the raw material attachment when raw material drops into hardly and are stranded in the problem that raw material drops into the inner surface of chute.Certainly, when dry raw materials such as slags, exist and discharge and the raw material collided with turntable from the lower ending opening of raw material input chute, beat on a spinstand because of impulsive force during collision, thus make raw material unstable to the supply in the gap of pulverization roller and turntable, and then the problem that the crush efficiency of raw material reduces.
Particularly, when the raw material of center chute-type drops into chute, it is large that the falling speed of raw material drops into chute than the raw material of side chute-type, therefore because of dry raw material on a spinstand takeoff and the problem of the destabilization of raw material supplying that causes becomes deep.
Therefore, in the vertical roller mill of the pulverization process for dry raw material, in order to reduce the speed of raw material when arriving turntable, suppressing raw material takeofing on a spinstand, and mostly adopting the raw material of side chute mode to drop into chute.
