Mineral aggregate screening device

Abstract

The invention belongs to the technical field of mineral aggregate processing, and particularly relates to a mineral aggregate screening device. By aiming at the problems that the mass of mineral aggregate is large, large kinetic energy is generated when the mineral aggregate falls from a high position, irreparable wear can be generated in equipment due to long-term impact and scouring of the mineral aggregate, consequently, part of structures in the equipment of this kind need to be replaced or maintained regularly, and durability is poor, the following scheme is provided, wherein the mineral aggregate screening device comprises a screening box, base blocks are fixed to the inner wall of the top of the screening box through screws, and long shafts are fixed to the outer walls of one sides of the base blocks through screws. By arranging sliding plates, protruding strips and tension springs, mineral aggregate makes contact with the sliding plates when sliding downwards, friction force with the mineral aggregate is increased under the action of the protruding strips, the sliding plates are pulled out, the tension springs drive the sliding plates to be recycled, the sliding plates generate reciprocating pulling-out and returning dynamic states through the action, kinetic energy of the falling mineral aggregate can be effectively counteracted, the impact force during falling is relieved, and the durability of machinery in the device is improved.

Description

technical field [0001] The invention relates to the technical field of mineral material processing, in particular to a mineral material screening device. Background technique [0002] Due to the large-scale development and utilization of mineral resources, the amount of available resources is continuously decreasing, resulting in a decrease in the quality of raw ore mining, and subsequent processing such as smelting has increasingly high requirements for the quality of beneficiation products. Therefore, it is necessary to use beneficiation equipment to screen the mined ore. [0003] In the process of mineral material screening, the mineral material needs to be poured into the screening equipment from above the screening equipment. Although the internal mechanism of this type of screening equipment is set to be made of strong rigid materials, due to the large quality of the mineral material, A large kinetic energy is generated when falling from a high place, and its long-ter...

[0003] In the process of mineral material screening, the mineral material needs to be poured into the screening equipment from above the screening equipment. Although the internal mechanism of this type of screening equipment is set to be made of strong rigid materials, due to the large quality of the mineral material, Large kinetic energy is generated when falling from a high place, and its long-term impact and erosion will also cause irreparable wear and tear on the inside of the equipment. Therefore, some internal structures of this type of equipment need to be replaced or maintained regularly, and the durability is poor.
