SU77325A1 - Ball mill with oscillatory motion of the hull - Google Patents

Description

We offer, according to the invented 1-: o, ball mill with oscillatory motion of the body is designed d .; grinding different materials (ore, coal, grain, etc.).

The mill (Fig. 1 to 2) consists of a massive bowl 1 connected by means of inclined springs or springs 2 with a plate 3 mounted on shock absorbers 4. A vibrator 5 is placed on the plate, which creates rocking vibrations through elastic spring of inclined springs 2, operating at a resonant frequency, are transmitted to a cup / filled with crushing bodies 8.

Under the action of these vibrations, the crushing bodies 8 jump at a frequency that is different from the frequency: the bowl vibrations, whirling along its bottom. The amplitude of oscillations of crushing bodies is several times greater than the amplitude of oscillations of the bowl itself.

The work of the mill is as follows.

With the help of the feeder 6, the material to be crushed is fed into the bowl, which, under the action of circular vibrations, begins to move along the bottom of the chap: n 1. The tearing bodies jumping around the bowl hit and fall to the material and crush the material. The crushed material under the action of inclined oscillating vibrations, r rises upwards along the conical surface of the bead of the bowl and unloads through the opening 7. The tank dimensions and the form of its section can be selected for the tank, at which particles crushed to the required dimensions will be poured over the edge of the bowl. The rest of the material is in the bowl until it is crushed by crushing bodies to the required size. This process occurs continuously and automatically.

In some slips, to speed up the process of separating the crushed product, the bead of the bowl will be provided with special wrinkles, grooves (or grooves) or holes.

To increase the capacity of the mill, it can be equipped with several bowls installed one hell to another.

Subject invention

1. Ball mill with oscillatory dvilieniem case, about t825

l and h with the fact that the mill housing is made in the form of a bowl, mounted on the inclined plank springs, arranged around the circumference of the mill housing.

2. Sharov-mill no. 1, about tlc chu HI and the fact that for the oscillatory movement

(Cornus) mill1, s used a vibrator mounted on the bottom of the bowl on the bottom or on the mill support frame.

3 Sharov Mill in p. 1 and 2, characterized in that openings, grooves and grooves are arranged in the edges of the bowl to remove the finished material.
