Abstract

The invention relates to the grinding of ores, materials by means of drum mills (BM) in enrichment and production of building materials. The purpose of the invention is to increase the reliability of BM in operation. Two grinding drums (PBs) are parallel, symmetrically mounted by means of bearings in the faceplate, which acts as a carrier. The BM drive shaft located adjacent to it has at its ends an eccentric neck and counter-bar, which are carried along the connecting rod. The ends of the rods are rigidly attached to the opposite ends of the corresponding PB. When the shaft rotates, the PBs make a circulating motion. The eccentricities of the location of the necks of the shaft and PB are the same. 2 Il.

Description

The invention relates to the grinding of ores, materials, namely, drum mills of centrifugal action, and can be used in the enrichment, production of construction and special materials.

The purpose of the invention is to increase the reliability of the mill in operation.

FIG. 1 shows a structural diagram of the proposed mill in side view without a bed; in fig. 2 - the same plan view.

The washer, 1 of the mill, mounted on the bed 2 by rotation supports and acting as the carrier, carries the main and additional floor drums 3 with the working medium 4 in them. The drums are located in the faceplate parallel and diametrically opposed to the possibility of 4 relative rotation in a portable rotation with the faceplate 1. The eccentric shaft 5 mounted on the base 2 in the supports 6 and driven through the transmission 7 is made with an eccentric neck and countershielding 8 bearing the heads of the main and additional rods 9, the ends of which are rigidly attached to the opposite end parts of the respective drums 3. It is obvious that the eccentricities of the axes of the necks 8 relative to the axis of rotation of the shaft 5 and the axes 10 b The arabanas relative to the axis of rotation 11 of the faceplate 1 are the same. Drums 3 can be oriented in space both horizontally and vertically. The mill can be equipped with a product pneumatic discharge system (not shown). During the operation of the mill, the drums 3 with medium 4, as a result of the rotation of the shaft 5, make a circulating motion, i.e., they retain, together with the rods 9, orientation in space, which leads to intensive grinding of the material. Symmetrical arrangement of the drums provides a dynamic balance melstad
