SU1650251A1 - Vibratory mill - Google Patents

Abstract

The invention relates to the grinding of ores. rocks by vibration mills (VM) in the mining and processing, chemical, and other industries. The goal is to increase efficiency. The grinding drum (PB) 1 with its trunnions or ends 2 is mounted in the right and left autonomous gearboxes (AP) 3, each of which contains a central gear wheel, several gears with unbalances and a housing elastically connected to the frame 5 of the VM. The gears of the AP are synchronized by the PB itself while rotating the gears of the AP from the engine 11 through the transmission 12, as a result of which the PB is rotated and simultaneously oscillates with respect to the 5 VM frame. The central low-speed shaft AP can also be a PB axle bearing the gear wheel AP. 2 Il.

Description

The invention relates to the grinding of ores, rocks, solid materials, namely, vibratory mills, and can be used in mining, construction, chemical and 5 other industries for grinding, activation, mixing and surface treatment.

The purpose of the invention is to increase the efficiency of the mill. 10

Figure 1 shows a diagram of a mill; figure 2 - diagram of the gearbox.

The mill drum 1 (Fig. 1) with its ends or trunnions 2 is mounted in the right and left gears 3. When performing a drum with feedthrough trunnions during continuous grinding mode (Fig. 1), each trunnion can directly carry the gear wheel of the gearbox, and without feedthrough trunnions when in cyclic operation, the end of the bar-20 ban can be articulated with the gear shaft through an intermediate detachable connection (figure 2). In both cases, the right and left gears 3 are structurally autonomous, and kinematically synchronized by the drum 1 itself.

Each gearbox 3 is elastically connected by its body 4 with the frame 5 of the mill, and the frame can be supported on the base 6 by means of elastic elements 7.

In the housing 4 (figure 2) mounted gear 8 on a low-speed shaft and gears 9 with unbalances 10 on high-speed shafts. A low-speed shaft with its supports of 30 ductors and together with them a drum, i.e. a pair of gears 3 is the drive at the same time and rotation, and vibrations of the drum 1.

In FIG. 2, circular oscillations are generated, and in the general case, each gearbox can be with a different number of gears and gears, generating oscillations of the desired path. The drive motor 11 can be mounted on the gearbox or on the frame above it and is equipped with a transmission 12 preferably on a high-speed shaft.

In an embodiment with a pin, the grinding chamber by means of hoses 15 can be connected as a part of the vacuum system with a feeder 14, a pipe 15 and a separator 16 with a product pipe 17. In the process of the mill, the drum 1 rotates and simultaneously oscillates together with gears on elastic elements relative to the frame 5.

With sufficient massiveness of the frame, its vibration can be minimized, thereby increasing the efficiency of the mill.
