Description

TECHNICAL FIELD

[0001] The utility model belongs to mica processing equipment technical field relates to a mica ore shot blasting crusher. BACKGROUND

[0002] Mica ore often adopts the stone crusher to break, the stone crusher is through the rotor frame to throw out the material, makes the ore block to hit the impact plate and realizes the broken of the stone block, this kind of mode can only preliminarily refine the large size ore block, and the small particle size and small size ore block are difficult to continue to refine due to the weak impact strength after throwing out and hitting the impact plate, therefore, generally need to carry out multiple classification crushing and grinding to the small size ore block, in addition, the noise of this kind of ore crusher is big, and the dust pollution is big. SUMMARY

[0003] The utility model discloses a kind of mica ore shot blasting crushers for the above problems existing in prior art, and the technical problem to be solved by the utility model is how to avoid dust.

[0004] The utility model discloses a kind of mica ore shot blasting crushers, it is characterized by including transversely fixed on the mounting shaft of rack, rotationally connected on the mounting shaft of drum and the separation rod in drum, the drum is rotated by a drive mechanism, the separation rod is fixed on the mounting shaft, the separation rod is close to the inner wall of drum above mounting shaft axis, the outer wall surface of drum is intermittently provided with several permanent magnet strips, the drum has several iron impact balls.

[0005] Further, the permanent magnet strip and the axis of drum are 70~90 ° inclination.

[0006] Further, the separation rod is the rotationally connected rod of mounting shaft.

[0007] Opening is set on the flat side wall of drum, opening is closed by openable material door, material is placed in drum after rotation, its rotation speed can be smaller, impact ball is lifted to high position by permanent magnet strip, under the action of separation rod, impact ball loses magnetic attraction and falls, and impact force is generated to material in drum, the breakage of ore block is realized, in addition, material can be constantly turned over, and grinding effect is formed between material and impact ball in material turning process, which can further refine ore block, in a crushing cycle, larger size ore block can be directly refined to the state of coexistence of fragments and powder, dust can be avoided, and noise is smaller due to lower speed. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 It is the structure diagram of the crusher.

[0009] Figure 2is a lateral cross-sectional view of the rotary drum.

[0010] In the figure, 1 is a mounting shaft; 2 is a rotary drum; 3 is a separating rod; and 4 is a permanent magnet strip. DETAILED DESCRIPTION

[0011] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0012] As shown in Figure 1 and Figure 2 The mica ore shot blasting crusher includes a mounting shaft 1 fixed transversely on a rack, a rotary drum 2 rotatably connected to the mounting shaft 1, and a separating rod 3 located in the rotary drum 2. The rotary drum 2 is driven to rotate by a driving mechanism. The separating rod 3 is fixed to the mounting shaft 1 and is close to the inner wall of the rotary drum 2 above the axis of the mounting shaft 1. A plurality of permanent magnet strips 4 are arranged on the outer wall surface of the rotary drum 2 at intervals. The rotary drum 2 has a plurality of iron impact balls.

[0013] The permanent magnet strips 4 are inclined at an angle of 70-90° to the axis of the rotary drum 2. If the permanent magnet strips 4 are inclined, the dropping time of each ball is different when the separating rod 3 forces the impact balls to drop, and the probability of mutual impact of the impact balls is relatively small, and the damage to the lining of the rotary drum 2 is also relatively small. The separating rod 3 is a rotary rod rotatably connected to the mounting shaft 1.

[0014] A material port is formed on the flat side wall of the rotary drum 2 and is closed by an openable material door. After the material is placed in the rotary drum 2, it is rotated at a relatively low speed. The impact balls are lifted to a high position by the permanent magnet strips 4, and under the action of the separating rod 3, the impact balls lose the magnetic attraction and drop, producing an impact force on the material in the rotary drum 2, achieving the damage and refinement of the ore blocks. In addition, the material can be continuously turned over, and a grinding action is formed between the material and the impact balls during the turning process, which can further refine the ore blocks. In one crushing cycle, the large ore blocks can be directly refined to a state where fragments and powders coexist, and dust can be avoided. Since the rotation speed is low, the noise is also low. This equipment is equivalent to a ball mill with low rotation speed, but the impact balls can be lifted by magnetic attraction, and the movement trajectory of the impact balls is more regular to a certain extent.

[0015] The specific embodiments described in this document are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
