Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separator equipment, in particular to a magnetic separator which can evenly separate ore and has a slag separation screen recovery function. Background Art

[0002] In the magnetite beneficiation production process, magnetic separation is the core component of the beneficiation process. The effect of magnetic separation directly affects the concentrate recovery rate. The slurry concentration is one of the main factors affecting the magnetic separation effect of the magnetic separator.

[0003] If the pulp concentration is too high, resulting in too high a separation concentration, it will seriously affect the concentrate quality. This is because the concentrate particles are easily covered and wrapped by finer gangue particles and cannot be separated, and they are selected together, which reduces the grade. If the pulp concentration is too low, that is, the separation concentration is too low, it will increase the flow rate and shorten the separation interval, causing some fine magnetic particles that should have had a chance to come up to fall into the tailings, increasing the tailings grade and causing losses.

[0004] When traditional magnetic separators are performing separation operations, uneven ore distribution by the feeder will cause large differences in local concentration in the magnetic separator, thereby reducing the magnetic separation effect, affecting the quality of the concentrate or causing metal loss. At the same time, the existing magnetic separator feeders are often blocked during use due to large particles or debris in the ore flow, causing long-term shutdowns, troublesome handling, and reduced equipment utilization.

DETAILED DESCRIPTION

[0020] like Figure 1-4 As shown, a magnetic separator capable of evenly separating ore and having a slag screen recovery function comprises a magnetic separator body 1, a fan-shaped ore separation bucket 2 is provided above the feed trough of the magnetic separator body 1, and the fan-shaped ore separation bucket 2 is installed on the magnetic separator body 1 through a support frame 7.

[0021] The fan-shaped ore separation bucket 2 is provided with a V-shaped ore separation guide plate 3, through which efficient flow diversion is performed, so that the ore can be evenly fed to the feed trough of the magnetic separator.

[0022] An inclined slag screen 4 is provided on one end of the fan-shaped ore separation bucket 2 away from the feed trough. An inclined slot 8 is provided on the fan-shaped ore separation bucket 2 , and the slag screen 4 is inserted into the slot 8 .

[0023] A pre-storage component is provided on the right side of the slag screen 4, and the pre-storage component includes a pre-storage tank 10 connected to the fan-shaped ore separation bucket 2, an inclined plate 11 is provided inside the pre-storage tank 10, a pressure sensor 12 is provided below one end of the inclined plate 11, and the other end of the inclined plate 11 is hinged on the pre-storage tank 10, and the side of the pre-storage tank 10 close to the lower end of the inclined plate 11 is an opening, and a baffle 13 is provided on the outside of the opening, and the baffle 13 is controlled to rise and fall by a cylinder 14 installed on the ore feeding chute 6. A collecting basket 9 is provided below the pre-storage component. When the pressure sensor 12 senses that the material in the pre-storage tank 10 reaches a set value, the cylinder 14 controls the baffle 13 to rise, so that the opening opened on the side wall of the pre-storage tank 10 is opened, and the material rolls into the collecting basket 9 by its own weight through the inclined inclined plate, and does not need to be cleaned manually, which is very convenient.

[0024] L-shaped guide plates 15 are provided outside the two side walls of the baffle 13 , and the L-shaped guide plates 15 are fixed on the side walls of the pre-storage tank 10 .

A channel is reserved between the guide plate 5 and the slag screen 4, and a feeding chute 6 is connected to the right side of the pre-storage component, so that the minerals will not fall directly into the pre-storage tank 10 after passing through the feeding chute 6, but will flow back to the top of the slag screen 4 through the guide plate 5, and roll down due to their own weight. Small particles of material will directly pass through the slag screen 4, and large particles of material will fall into the pre-storage tank 10.
