能も有している。First, the granular material is loaded into the cone-shaped portion 2 of the main body of the apparatus. The cone-shaped portion 2 is a device for vibrating by the vibrating element 1 to perform quantitative cut-out of powder and granules, and since it can have a considerable capacity, it functions as a hopper (storage tank). I also have.

Go away. The amount of the powder or granules to be sent out is restricted by the height of the spiral fold from the inner surface of the cone and the protruding length of the partition plate 3 on the way to the drop port. That is, the higher the height of the spiral fold from the inner surface of the cone or the shorter the overhanging length of the partition plate 3, the more the amount of powder or granules delivered. The partition plate 3 effectively acts on the quantitative cutout.

かった。Next, an example of use of the embodiment apparatus shown in FIG. 1 will be described. 50 g of coal having 100 mesh or less and 80% is charged into the continuous feeding apparatus shown in FIG. The continuous supply test was conducted according to 3 out of 5 vibration intensities of the vibration element 1. Figure 2
Is a plot of the coal supply amount with respect to the elapsed time at this time. The vertical axis is the coal supply amount, the horizontal axis is the elapsed time,
The gradient shows the coal feed rate. In addition, the straight line numbers in the figure represent the vibration strength of the vibration element, and the larger the number, the stronger the vibration. In this figure, since the gradient is a straight line, it can be seen that the supply rate is constant. When the vibration intensity of the vibrating element 1 was set to 2 and 5 in 5 steps, the vibration element 1 was also placed according to FIG. From this result, it was also found that the supply amount of coal can be controlled by changing the vibration intensity of the vibration element 1.
