[0004] In the prior art, when processing barite powder, a jaw crusher is usually used to perform preliminary crushing of the barite ore, and further processing is performed through grinding, flotation and the like.

DETAILED DESCRIPTION

[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] like Figures 1 to 14 A barite powder jaw crushing device for mining and processing shown in the figure comprises a frame 1, the top of the frame 1 is rotatably connected to an eccentric shaft 2, a movable jaw frame 3 is arranged inside the frame 1, the top of the movable jaw frame 3 is rotatably connected to the center position of the eccentric shaft 2, a fixed jaw frame 4 is movably connected inside the frame 1, a crushing jaw plate 5 is arranged on one side adjacent to the movable jaw frame 3 and the fixed jaw frame 4, a movable restraining mechanism is connected to the movable jaw frame 3, and a driving mechanism is connected to the eccentric shaft 2; The crushing jaw plate 5 is connected with a disassembly and fixing mechanism, and a plurality of contact strips 6 are arranged on the adjacent sides of the two crushing jaw plates 5, and a fractal contact mechanism is connected between the contact strips 6 and the corresponding crushing jaw plates 5, and a fitting crushing mechanism is connected to the contact strips 6; when working, the prior art usually uses a jaw crusher to perform preliminary crushing of the barite ore when processing barite powder, and further processes it by grinding, flotation, etc. When the barite ore is jaw-broken, the barite ore is crushed between the moving jaw and the static jaw by the reciprocating movement of the moving jaw. When the volume of the barite ore is large, the contact area between the barite ore and the surface of the moving jaw is small and relative sliding is easy to occur, thereby making the barite powder The barite ore is always located above the movable jaw and the static jaw and cannot be squeezed and crushed. In addition, since the distance between the movable jaw and the static jaw is always fixed, when multiple barite ores are crushed at the same time and are of different sizes, it is difficult for the movable jaw and the static jaw to effectively crush the smaller barite ores, thereby reducing the crushing effect and uniformity of the barite ore. The technical solution can solve the above problems. The specific working method is as follows: the barite ore for crushing is continuously transported between the two crushing jaw plates 5, and the eccentric shaft 2 is eccentrically rotated along the rotating connection of the frame 1 through the action of the driving mechanism, so that the movable jaw frame 3 moves along the rotating connection of the eccentric shaft 2. And the movable jaw frame 3 is constrained to move by the action of the movable constraint mechanism, so that the movable jaw frame 3 is reciprocated by the eccentric rotation of the eccentric shaft 2. When the barite ore is located between the movable jaw frame 3 and the fixed jaw frame 4, the crushing jaw plates 5 on the adjacent sides of the movable jaw frame 3 and the fixed jaw frame 4 form a crushing cavity, and contact the barite ore through multiple contact strips 6. In the contact process, the multiple contact strips 6 are moved in coordination according to the lateral profile of the barite ore by the action of the fractal contact mechanism, so that the multiple contact strips 6 are adapted to the lateral contact positions of the barite ore, thereby increasing the lateral contact area between the barite ore and the corresponding contact strips 6, so that when multiple barite ores are crushed, Multiple contact strips 6 can perform corresponding fractal contacts according to the sizes and shapes of multiple barite ores, thereby improving the crushing effect and crushing rate of the barite ores. During the process of the contact strips 6 on the two crushing jaw plates 5 squeezing and crushing the barite ore, the longitudinal contact area between the single contact strip 6 and the barite ore is increased through the action of the fitting crushing mechanism, and corresponding fitting is performed according to the longitudinal profile of the barite ore, thereby reducing the relative sliding between the barite ore and the contact strip 6 during the crushing process and increasing the contact friction, so that the larger barite ore can smoothly enter between the two crushing jaw plates 5, reducing the situation where the barite ore cannot enter the crushing chamber due to its large volume.

One end of the movable bar 12 on the limit baffle 9 moves inside the strip shell 11, and as the contact bar 6 and the barite ore are in contact and squeezed, the movable bar 12 is in contact and squeezed with the metal balls inside the strip shell 11, and the metal balls are freely rolled inside the strip shell 11 for active filling until the space inside the strip shell 11 is completely filled with one end of the multiple movable bars 12 and the metal balls. The movable bars 12 cannot move, so that the multiple contact bars 6 move in coordination with the lateral profile of the barite ore during contact with the barite ore, thereby increasing the lateral contact area between the contact bar 6 and the barite ore, improving the crushing effect and crushing rate when multiple barite ores are crushed at the same time, and reducing omissions during the crushing process.
