In such a vertical crusher, the raw material supplied to the central portion of the rotary table by the raw material feeding chute 17 receives the centrifugal force in the radial direction of the rotary table 3A and slides on the rotary table 3A. At times, the rotary table 3A receives a force in the rotation direction, and the rotary table 3A
It slides with A and performs a rotation somewhat slower than the rotation speed of the rotary table 3A. The above two forces, that is, the radial direction force and the rotational direction force are combined, and the raw material is the rotary table 3.
A spiral locus is drawn on A to move to the outer peripheral portion of the rotary table 3A. Since the roller is pressed against the outer periphery and is rotating, the raw material in which the spiral is drawn enters the crushing roller 4 and the rotary table 3A from a direction forming an angle with the roller axial direction and is bitten. It is crushed and crushed.

In recent years, the demand for the product particle size of pulverized raw materials has been increasing year by year, and it has become more and more desired to make the product particle size finer, which is called fine pulverization or ultrafine pulverization. Therefore, it becomes difficult to meet the demand with a single crusher. Therefore, for example, before the raw material is put into a finishing mill such as a ball mill, a vertical crusher is used as a preliminary crusher. A method has been adopted in which pulverized products are sieved with a vibrating screen and only fine powder is supplied to a finishing mill. FIG. 6 shows a flow sheet in this case, in which the raw material of the raw material hopper 60 is pulverized by the vertical pulverizer 1 through the constant feed ware 70, and the product is guided to the vibrating screen 90 through the bucket elevator 80 and screened. Only the fine powder is crushed by the finishing mill (ball mill) 100, and the oversized product is again preliminarily crushed by the vertical crusher 1.

In the above-described two-stage crushing by the preliminary crushing and the main crushing, the product of the preliminary crushing is sieved by the vibrating sieve, and the maintenance of the sieve becomes a problem. That is, for example, in the case of a raw material that is particularly abrasive, such as when crushing cement clinker containing slag, it is generally necessary to inspect and replace the vibrating screen every 2 to 3 months. However, it was inevitable to stop the operation for several hours, and the decrease in productivity due to the operation stop was unavoidable. In addition, it was difficult for the vibrating sieve to easily change the sieving / classifying point of the vibrating sieve according to the change of the raw material type and the change of the properties of the supplied raw material (grindability, water content).

Embodiments of the present invention will be described in detail below with reference to the drawings. 1 to 4 relate to an embodiment of the crushing equipment of the present invention, FIG. 1 is a flow sheet of the crushing equipment, and FIG. 2 is a longitudinal section showing another embodiment of an inertial utilization type classifier (hereinafter referred to as inertial classifier). Fig. 3 is a vertical sectional view showing another embodiment of the inertial classifying device using a table feeder in place of the belt feeder, and Fig. 4 is a track diagram of particles horizontally discharged into the air. .6 shows the case where sand particles having a particle size of 0.15 to 1 mm are discharged at an initial velocity of 15 m / sec. As can be seen from Fig. 4, the track varies depending on the particle size depending on the air resistance, and the coarser particles reach farther. The inertia classifier is a type of gravity classifier that applies this principle. As the initial velocity increases, the tracks move to the right in the figure, so the classification point can be adjusted by the speed of the belt conveyor. Sh and Sv in the figure indicate the horizontal distance and the vertical distance (m), respectively, and Dp indicates the particle diameter (mm).
Indicates. In this type of classifier, it is important to improve the dispersion of particles, and if the supply amount is too large, the particles collide with each other and the accuracy of classification deteriorates.

The operation of the crushing equipment of the present invention constructed as described above will be explained. The crushing raw material is cut out from the hopper 60 by the constant feed ware 70, preliminarily crushed by the vertical crusher 1, and the fine powder is collected. The coarse particles are discharged from the lower annular space passage 14 while being directed to the dust device 120, and are guided to the inertial classification device 110. Then, the particles are discharged horizontally to the classification chamber by the high-speed belt conveyor 110a, and the fine particles are discharged from the front compartment, and the coarse particles are discharged from the far compartment.
And, the product granules and powder are bucket elevator 80b.
The powder is entered into the finishing mill 100 via the and pulverized. On the other hand, the coarse particles of the product are returned to the vertical crusher 1 by a transportation means such as a bucket elevator 80a. The fine powder product of the vertical crusher 1 collected by the dust collector 120 may be used as it is as a final product depending on the particle size, but when it does not reach the desired particle size, it is guided to the finishing mill 100.

Instead of the inertial classifying device 110 using the belt conveyor 110a shown in FIGS. 1 and 2, an inertial classifying device 110 using a table feeder 110m shown in FIG. 3 may be used. In any case, when the inertial classifier 110 is used, it is easy to change the classification point, and it is not necessary to replace parts in a short cycle (2 to 3 months) when using a vibrating sieve, and maintainability is improved. Is significantly improved. The inertial classifier generally has a drawback that the classification point is not sharper than that of a vibrating screen. However, the function of the inertial classifier 110 in the crushing equipment of the present invention is not a strict method of particle size selection of the final product, but a preliminary crushed product. Since the selection is for supply to the main crushing, the above-mentioned disadvantages do not become apparent.
It is durable enough to use.
