Description

Technical Field

[0001] The utility model relates to the technical field of feeding, in particular to a raw material crushing and feeding machine dedicated to high carbon ferromanganese production. Background Art

[0002] High carbon ferromanganese is an alloy composed of manganese and iron, produced by blast furnace method and electric furnace. Among them, electric furnace high carbon ferromanganese is mainly used in steelmaking as a deoxidizer, desulfurizer and alloy additive. In addition, with the advancement of medium and low carbon ferromanganese production technology, it can also be used to produce medium and low carbon manganese steel. It is still widely used in China. In the specific production process, raw materials such as manganese ore, coke and lime need to be crushed and sent into the blast furnace for smelting through a feeder.

[0003] Prior art, such as a mineral crusher for mining disclosed in announcement number CN213825201U, comprises a box body, two sides of the box body are provided with rotating holes, bearings are sleeved in the rotating holes, rotating columns are sleeved in the bearings, stone crushing rollers are mounted between the rotating columns, stone crushing rollers are mounted with stone crushing blades, two sides of the box body are provided with support plates, a motor is mounted on the support plates, a rotating column is mounted on the output end of the motor, a fixed rod is mounted on the inner wall surface of the box body, a movable plate is rotatably mounted on the fixed rod, a movable rod is rotatably mounted on the movable plate, a telescopic rod is mounted on the inner wall of the box body, and a movable rod is mounted on the end of the telescopic rod.

[0004] The device demonstrated by this technology can drive the rotating column to rotate through the output end of the motor, and the rotating column drives the crushing roller to rotate. As the two crushing rollers rotate in opposite directions, the crushing blades crush the ore. The device only uses one crushing operation. The crushing rollers have to process ores of various sizes at the same time. The crushing knife is slower when processing large-volume ores, which affects the processing of medium-sized ores and results in slower ore crushing efficiency. Therefore, this device has certain shortcomings. Summary of the invention

[0005] The utility model aims to solve the problem of low crushing quality of crushing feeders in the prior art, and proposes a raw material crushing feeder dedicated to high carbon ferromanganese production.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0012] Preferably, crushing teeth are welded on the crushing roller, and the crushing teeth are evenly arranged in a fan shape on the outer surface of the crushing roller.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The utility model performs preliminary crushing of raw materials by arranging rotor crushing knives and stator crushing knives. Large-volume raw materials are crushed here, and raw materials with a diameter smaller than the distance between the rotor crushing knives and the stator crushing knives directly fall to the bottom and are crushed by the crushing roller. Large-volume raw materials above will also fall to the crushing roller after being crushed.
