Problems solved by technology

However, for some minerals with relatively high hardness, they need to be crushed for a long time to form the required size. For the crushing equipment, the above-mentioned minerals not only lead to slow processing efficiency during the processing process, but also large-sized minerals Long-term impact with the crushing equipment will aggravate the wear of the crushing equipment and affect the service life of the equipment

Embodiment 1

[0027] Such as figure 1 The shown hot ore crushing equipment based on liquid auxiliary treatment includes a crushing body 1, and a crushing roller shaft 2 is arranged inside the crushing body 1, which is driven by a drive motor 3 arranged outside the crushing body 1; the crushing roller A plurality of crushing end teeth 4 extending perpendicular to the axis of the crushing roller shaft 2 are arranged on the shaft 2, and a plurality of auxiliary crushing end teeth 5 are arranged on the inner wall of the crushing body 1, and the crushing end teeth 4 and the auxiliary crushing end The teeth 5 are distributed alternately with each other. Each crushing end tooth 4 and auxiliary crushing end tooth 5 are respectively provided with a plurality of pressure sensors 6; the crushing roller shaft 1 adopts a hollow structure, and a plurality of injection chambers 7 are arranged inside it, and a plurality of injection chambers 7 It is evenly distributed in the axial direction of the crushin...

Embodiment 2

[0032] As an improvement of the present invention, such as Figure 4 and Figure 5 As shown, among the crushing end teeth 4 and the auxiliary crushing end teeth 5, the corresponding position of each group of pressure sensors 6 is provided with a circularly extending detection tank 14, and the pressure sensors 6 are all arranged in the detection tank 14; the inside of the detection tank 14 is provided with a rubber protection layer 15, which extends annularly along the detection tank 14, and the pressure sensor 6 is arranged between the rubber protection layer 15 and the detection tank 14; the rubber In the protective layer 15 , a plurality of detection port holes 16 extending from the end surface of the pressure sensor 6 to the outer end surface of the rubber protective layer 15 are provided at corresponding positions of each pressure sensor 6 .

[0033] By adopting the above technical scheme, it can prevent the pressure sensor from protruding from the surface of the crushing...

Embodiment 3

[0036] As an improvement of the present invention, such as Figure 5 As shown, each detection port hole 16 is provided with an air storage chamber 17 extending perpendicular to the axial direction of the detection port hole 16, which can increase the air inside the detection port hole, so that the air pressure formed by it is more effective. Obviously, the detection accuracy of the pressure sensor is further improved.

[0037] The remaining features and advantages of this embodiment are the same as those of Embodiment 2.

Abstract

The invention discloses liquid auxiliary treatment-based hot ore crushing equipment. The equipment comprises a crusher body, wherein a crushing roll shaft is arranged in the crusher body; a plurality of crushing end teeth which extend along a direction vertical to an axis of the crushing roll shaft are arranged on the crushing roll shaft; a plurality of auxiliary crushing end teeth are arranged on the inner wall of the crusher body; a plurality of pressure sensors are arranged on the crushing end teeth and the auxiliary end teeth; a plurality of liquid injection chambers are arranged in the crushing roll shaft; a cutting liquid slot which is communicated with the liquid injection chamber is formed outside the crusher body; a pressure pump is arranged in each liquid injection chamber; and auxiliary cutting nozzles are connected with the pressure pumps. According to the liquid auxiliary treatment-based hot ore crushing equipment, high-pressure liquid flow injection can be carried out on ores through the liquid injection chambers in the crushing roll shaft in the working process of the hot ore crushing equipment, so that the ores can be crushed under the cutting of the liquid flows, and then the ore crushing efficiency and precision can be effectively improved.

Description

technical field [0001] The invention relates to a mineral processing equipment in a metallurgical process, in particular to a hot ore crushing equipment based on liquid auxiliary treatment. Background technique [0002] In the process of deep processing of minerals, it is necessary to preliminarily process the mineral raw materials into the size required by the relevant process, so as to avoid damage to the relevant process equipment and improve processing efficiency. The existing preliminary mineral processing procedure is usually to crush the heated mineral raw materials, that is, to carry out hot ore crushing processing. However, for some minerals with relatively high hardness, they need to be crushed for a long time to form the required size. For the crushing equipment, the above-mentioned minerals not only lead to slow processing efficiency during the processing process, but also large-sized minerals The long-term impact with the crushing equipment will aggravate the w...
