Embodiment 1

[0023] like figure 1 As shown, a cone crushing structure for ore crushing includes a shell 1, a material inlet 2, a crushing cone 3, a crushing receiver 4, an exhaust fan 5, a main rotating shaft 6, a main motor 7 and a discharge port 8 The feed inlet 2 is arranged on the top of the shell 1, the both sides of the feed inlet 2 are provided with damping plates 21, the crushing cone 3 is arranged directly below the feed inlet 2, and the crushing cone 3 and The main rotating shaft 6 is fixedly connected; the crushing cone 3 rotates under the drive of the main rotating shaft 6; the central axis of the crushing cone 3 is on a straight line with the central axis of the feeding port 2, and it is characterized in that, Described pulverizing receiving body 4 comprises two semi-ring receiving bodies on the left and right, and described two semi-ring receiving bodies surround pulverizing cone 4 annularly; Described semi-ring receiving body comprises upper crushing surface 41, lower crushi...

Embodiment 2

[0029] like Figure 2~Figure 4 As shown, a cone crushing structure for ore crushing includes a shell 1, a material inlet 2, a crushing cone 3, a crushing receiver 4, an exhaust fan 5, a main rotating shaft 6, a main motor 7 and a discharge port 8 ; The feed inlet 2 is arranged on the top of the shell 1, and the both sides of the feed inlet 2 are provided with shock absorbing plates 21, and the shock absorbing plates 21 are arranged on both sides of the feed inlet 2, and the shock absorbing plates 21 is set in multiples, and the shock absorbing plate 21 is arranged at intervals up and down. When the ore is transported into the material inlet 2, it will directly fall from the material inlet 2 to impact the crushing cone 3, and the long-term impact will affect the crushing cone. 3, the initial velocity of the ore entering can be slowed down by the feeding damping plates 21 on both sides. After repeated shock absorption, the ore will enter the surface of the crushing cone 3 at a l...

Abstract

The invention discloses a conical crushing structure for crushing ores. The conical crushing structure comprises an outer casing, a material inlet, a crushing cone, a crushing receiving body, an air suction fan, a main rotary shaft, a main motor and a material outlet, wherein the material inlet is arranged at the top part of the outer casing; damping plates are arranged at both sides of the material inlet; the crushing cone is arranged just under the material inlet, and is fixedly connected with the main rotary shaft; the crushing cone is driven by the main rotary shaft to rotate; the middle axis of the crushing cone and the middle axis of the material inlet are positioned on one straight line, the crushing receiving body comprises a left semicircular receiving body and a right semicircular receiving body, and the crushing cone is annularly surrounded by the two semicircular receiving bodies; each semicircular receiving body comprises an upper crushing surface, a lower crushing surface, an upper spring, a lower spring, a connecting rod, an air pressure cylinder, a pressure detector and a control unit; each upper crushing surface is connected with the corresponding upper spring, andeach lower crushing surface is connected with the corresponding lower spring; a piston rod of each air pressure cylinder is fixedly connected with the corresponding fixing rod.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a cone crushing structure for crushing ore. Background technique [0002] Ore is generally divided into lean ore, common ore and rich ore. Sometimes it is only divided into poor ore and rich ore, and there is no uniform standard for this division. During the mining process, a portable microscope is used to observe the ore. The ore observed by the portable microscope is called ore dilution. Ore dilution will increase transportation and processing costs and reduce production capacity and recovery rates in the ore processing sector. If the waste rock contains harmful impurities, it will also reduce the quality of the final product. The ore dilution is mainly expressed by the ore dilution rate, the ratio of the difference between the industrial ore grade and the mined ore grade to the industrial grade, expressed as a percentage. [0003] After the ore is mined, the ore needs to be...
