摘要： PURPOSE: To easily obtain a high-concn. coal/water slurry suitable as a boiler fuel even if difficultly combustible coal is used as a raw material, by previously crushing the feed coal to such an extent that the max. size of the coal particle is not more than a specified value, followed by wet crushing.
CONSTITUTION: Feed coal is previously crushed to such an extent that the max. coal particle size is not more than about 1,000W150μm by subjecting the feed coal to dry crushing, to drycrushing and dry classification, to wet crushing, or to wet crushing and wet classification. A coal/water slurry of coal concn. ≥about 500μm is prepd. by subsequent wet crushing. Thus it is possible to obtain a high-concn. coal/water slurry suitable as a boiler fuel even when difficultly combustible coal of a fuel ratio of about 1W3 is used as a raw material.

摘要： PURPOSE:To restrain the occurrence of self-excited vibration in the case the vibration level of a pulverizing part consisting of a turntable and pulverizing rollers exceeds a prescribed threshold by repeating respective operations for instantaneously performing the feeding stop and the excess feeding of a raw material until the vibration level becomes lower than the threshold. CONSTITUTION:A raw material 1 in a raw material bunker 14 is fed into a raw material feeding pipe 2 by a constant amt. by a belt wheel 16 of a raw material feeder 15. Next, the raw material 1 is dropped onto a turntable 3 and is pulverized by pulverizing rollers 4. Then, after the pulverized raw material 1 is transported upwards through between throat vanes 10, it is centrifugally classified by a rotary classifier 12 to discharge product fine powder from a fine powder discharge part 13. In this case, a rotating base 23 of a roller mill is provided with a vibration sensor 19 to detect the vibration amplitude and the vibration acceleration. When the detected vibration amplitude exceeds a prescribed threshold and is amplified as self-excited vibration, the belt wheel 16 and a damper member 17 each are controlled by a drive command device 22 through a signal processing device 20 and an arithmetic unit 21.

摘要： PURPOSE:To provide a tube mill which has good slurry pulverizing efficiency regardless of its large capacity, and size of whose shaft part and bearing is reduced by installing a means for holding the optimum quantity of slurry near the slurry outlet side inside a shell part. CONSTITUTION:A reduced diameter part 14 is extended from the slurry outlet side of a shell part 2 in which a raw material is pulverized into a slurry, and further, a trunnion shaft 20 of a trunnion bearing 24 for discharging the slurry is provided. Near the slurry outlet side inside the shell part 2, a partition plate 3 having an opening in the center which serves as a means for holding the optimum quantity of the slurry is installed. The reduced diameter part 14 is provided with scrape-up blades 15 for scraping up the slurry on the trunnion shaft 20 side. Then, the slurry is retained and held up to a level to maintain the suitable holdup quantity. The slurry in the reduced diameter part 14 is not retained in the bottom part of the reduced diameter part 14 but moved successively by the scrape-up blades 15 to be discharged even if the inner diameter 21 of the shaft of a tube mill 1 is small.

摘要： PURPOSE:To obtain the title apparatus economical for an increase in mill capacity by providing a slurry outlet port to the outer peripheral part of a mill outlet body and providing a coarse particle separating screen to the outside thereof. CONSTITUTION:In a coal slurry manufacturing apparatus grinding solid fuel coal along with water and a small amt. of an additive by a wet tube mill to slurry the same, a screen 19 removing the coarse particle solid contained in the prepared slurry is provided to a mill outlet and the removed coarse particle solid is returned to a mill inlet to be re-ground. A slurry outlet port 23 is provided to the outer peripheral part of a mill outlet body and the coarse particle separating screen 19 is provided outside the slurry outlet port 23. As a result, the size of a mill outlet bearing is set to a small diameter within a manufacturing limit and an achoring space can be contracted by arranging a mill screen to a mill outer periphery and, therefore, even after capacity is increased, the economically superior coal slurry manufacturing apparatus can be obtained.
