(54) DRAN BARREL

(57) The invention relates to the beneficiation of minerals, in particular, to the technology for processing alluvial deposits. The goal is to improve the quality of the distribution of screening products across ipuses. In a barrel consisting of a drum screen 1, a subarm casing 2, an exhaust port 3 and a rubber distributor 4, the subbarrelle 2 is not manufactured from screen 1. For this, it is suspended on a longitudinal axis 6 with the possibility of rotation around it. Suspension axis 6 is located above screen 1. During operation, one side of the distributor 4 is overloaded, the other side is underloaded. As a result, a torque occurs, which tends to turn the distributor 4 in the direction of underload. Moreover, the angle of rotation is proportional to the magnitude of the rotating MCH-LH-one, which in turn is projected to the magnitude of the overload. Thus, by means of the suspension, the armrest casing 2 is self-regulating. 2 Il.

The invention relates to the enrichment of minerals, in particular, to the technology of processing alluvial deposits, and can be used in the mining industry and other parts of the national economy, where there are operations for screening products.

The aim of the invention is to improve the quality of the distribution of screening products by gateways.

Figure 1 shows a barrel, a general view; Fig. 2 is a diagram of the occurrence of torque.

The drum barrel consists of a drum screen 1, a podbonechny casing 2, an exhaust port 3, a rubber dispenser 4, brackets 5, an axle 6. Due to the brackets 5 fixed on the casing 2, the latter is suspended under the screen 1 on an axis 6 with air rotation around it: axis 6 is mounted above screen 1, for example, in sub-pickles.

Due to the suspension with the location of the axis above the screen, the sub-housing casing becomes independent of the latter and becomes self-regulating. This is ensured by the fact that when the screen rotates, one side of the casing is always overloaded with screening products, which causes a torque M (Fig. 2), which tends to turn the casing against the rotation of the screen. Consequently, if this casing is rotated at a certain angle about, the outlet and the rubber dispenser will be displaced in the direction of a correspondingly weak sluice or other beneficiary device located under the distributor: the load on the right and left sides of the screen is more uniform; . uniformity of distribution of screening products is increased.

The distributor works as follows.

When the screen rotates 1, a product is caught out of the perforation through it, which is caught by the case-side casing 2. In this case, one side of the casing is underloaded, and the other side is overloaded. The greater the overload, the greater the turning moment M, which causes the housing 2 to be rotated by means of the brackets 5 on the axis 6, by an angle corresponding to the overload. At the same time, the exhaust port 3 with a rubber distributor is also shifted towards the underloaded concentrating apparatus installed under the screen 1. Depending on the load on any side of the casing 2, its installation is self-regulated and the corresponding distribution of the screening product occurs.
