摘要： PURPOSE:To improve grinding efficiency and to eliminate the need for a disintegrator and to grind the brittle material such as cement clinker by alternately forming an annular recessed part and an annularly projecting part to a pair of respective rolls and forming the oblique faces to the respective annular recessed part and forming the oblique faces whose width is made narrower as reaching the tip parts to the respective annularly projecting parts. CONSTITUTION:Both rolls 1, 2 are mutually rotated to the inside at the same velocity and cement clinkers 8, 9, 10 are supplied thereto. The clinker 8 introduced into the vicinity of the bottom part 6 of a recessed part 4 is compressed in the direction A7 by the tip part 7 and ground. The clinker 8 receives shearing force by difference of the circumferential speed together therewith and becomes fine powder. Further in this case, since the oblique face 11 of a projecting part 5 is tilted, compression force is made slightly weaker than the tip part 7. Therefor this clinker is partially moved in the direction A8. Deviation due to shearing is added to this partial movement. The ground brittle material is discharged from this roll device as fine powder without becoming a flake shape. Thereby the brittle material is pulverized at high efficiency.

摘要： PURPOSE:To eliminate easily a noise by multiplying an acoustic signal and a detecting end signal of an external noise signal by a ratio coefficient, taking a difference of both the signals, deriving a ratio of noise components in the detecting end signals of immediately before and after the generation of the noise, and setting the ratio coefficient to a correct value. CONSTITUTION:A sound of a crusher is detected by a sound detecting end 2, and an acoustic signal of a desired frequency band is amplified by a selecting amplifier 4. As for a detecting signal of a sound detecting end 3 for detecting an external noise, an acoustic signal of the same frequency band as the amplifier 4 is amplified by a selecting amplifier 5. Ratio multipliers 6, 7 multiply output signals of the amplifiers 4, 5 by the respective optional ratios, and vary an amplification degree of each acoustic signal. When an external noise is generated, an increase portion of the noise caused by the generation of the external noise is derived by a difference of the detecting signals of immediately before and after its noise, a ratio of an increase portion of the detecting signal of the sound detecting end 2, to said increase portion is derived, this ratio is multiplied to a ratio coefficient of the ratio multiplier 6, and this result becomes a ratio coefficient of the ratio multiplier 7. This ratio coefficient which is changed is multiplied to signals of the selecting amplifiers 4, 5, and the external noise is eliminated by taking a difference.

摘要： PURPOSE:To stably carrying out the pulverization by pulverizing brittle materials with a pulverizing means, classifying into coarse powder and fine powder with a classifying unit, taking out the fine powder as the product, compression-crushing the coarse powder, and supplying the compressed and crushed material to the pulverizing means together with the brittle material. CONSTITUTION:Classifying air SA is sent into a classifying chamber 11 through guide vanes 4 to form free eddy flow, and is formed into forced eddy flow by revolving classifying blades 3, and these eddy flows are discharged from a fine powder discharge duct 6 while swirling in the classifying chamber 11. In this state, fine powder Sb and coarse powder Sc are classified in the classifying chamber 11 by the balancing action between the centrifugal force and the reactional force of air. The classified fine powder Sb is entered into the fine powder discharge duct 6 to be recovered. The coarse powder is made into the compressed and crushed flakes in the compressing crushing unit 33, which are supplied to the pulverizing unit 14 together with clinker and gypsum as brittle materials SB. The flakes are effectively pulverized in the pulverizing unit 14 where the flakes and lumps of material to be pulverized are mixed, scattered and collided.

摘要： PURPOSE:To prevent the contact of the head part of a roller with the inner periphery of a table by forming a tolerant abrasion part to a tire on the side of the bottom part thereof and providing ribs to the outer peripheral surface of the tire in the axial direction thereof. CONSTITUTION:A roller 2 externally fitted with a tire 5 is placed on a table 1 in an inclined state and a gap 8 is formed between the outer peripheral surface 5c on the side of the head part 5b of the tire 5 and the part on the side of the center 1c of the table 1. When a vertical roller mill M is operated in this state and a stock to be ground is supplied to the gap between the table 1 and the roller 2, the stock is ground by the pressure between the table 1 and the roller 2. The tire 5 begins to abrade on the side of the bottom part 5a thereof by grinding work to be consumed but there is the gap between the head part 5b of the tire 5 and the inner periphery 1c of the table and grinding is performed without bringing both of them to a contact state. By this method, grinding work can be efficiently carried out.

摘要： PURPOSE:To keep the biting gap between a roller and a table by providing a cone inclined at an angle larger than the angle of repose of a material to be ground to the central part of the table and positioning the base end part of the cone in the vicinity of the head part of the roller. CONSTITUTION:When a material to be ground is supplied to a vertical roller mill M, the material to be ground is guided to a cone 2 to enter a biting gap 10 and ground by the pressing force between a tabel 1 and roller 3 while it receives centrifugal force to move toward the outer periphery 1c of the table 1. The cone 2 is inclined at an angle larger than the angle of repose of the material to be ground and the base end part 2a thereof is positioned in the vicinity of the head part 6b of a tire 6 and the material to be ground is bitten in the gap 10. Since the gap L between the head part 6b of the tire 6 and the inner periphery 1a of the table 1 is larger than the thickness dimension D of a tolerant abrasion part 7 even when the tire 6 is abraded on the side of the bottom part 6a thereof, the head part 6b of the tire 6 does not come into contact with the inner periphery 1a of the table 1.
