摘要： PURPOSE:To provide a vertical pulverizer capable of executing operation with good pulverizing efficiency by holding the height of fall of a feed raw material at the fixed appropriate one according to the variation in the thickness of a raw material layer during operation. CONSTITUTION:A movable chute 30 which is connected to a raw material throw-in chute 17 and is freely vertically ascendable and descendable, and an elevating/descending means (a hydraulic cylinder 40 or a servomotor 42) are installed, and a controller 50 for giving an operation command signal for changing the height of the lower end of the movable chute 30 according to the variation in the thickness of a raw material layer during operation to the elevating/ descending means is equipped.

摘要： PURPOSE:To reduce the quantity of coarse grains falling on an air port and discharged outside a mill without increasing the velocity of gas flow at the air port more than required. CONSTITUTION:In a vertical mill 13 constituted so that material to be ground 3 fed on a rotating grinding table 2 may be ground between the grinding table 2 and grinding rollers 4 which rotate, in press-contact with the grinding table 2 and following it, and the fine particles 5 obtained by grinding may be carried upward, laided on the flow of gas 7 from an air port 14 annularly arranged around the grinding table 2, the air port 14 constituted of a grating plate 17 whose upper surface is conical with an inclined angle larger than the angle of repose of the material to be ground 3. The size of the opening of open spaces 18 in the grating plate 17 is made smaller than the particle diameter of the material to be ground 3 and also the size of the depth of the open spaces 18 is made larger than that of the opening.

摘要： PURPOSE:To provide a vertical pulverizer less apt to cause sticking and developing of raw material powder and the clogging by it due to moisture in a raw material feeding chute. CONSTITUTION:A hot air feeding pipe 18 is concentrically arranged over the outer periphery of a raw material feeding chute 17 hanging down to the center of a vertical pulverizer 1 and also a hot air source for feeding hot air to the hot air feeding pipe 18 and an intake 18a of the hot air feeding pipe 18 are connected.
