Crushing and screening integrated machine

Abstract

The invention provides a crushing and screening integrated machine. A rack, a fixed jaw, a first movable jaw and a second movable jaw are included. A first toggle plate is arranged between the first movable jaw and the second movable jaw. A crushing cavity is formed between the fixed jaw and the first movable jaw, and a discharging port is formed in the lower portion of the crushing cavity. A first screen frame and a second screen frame are arranged at the lower portion of the first movable jaw and the lower portion of the second movable jaw correspondingly. The first screen frame moves alongwith the first movable jaw and is located below the discharging port and used for bearing and screening ore falling down from the crushing cavity. The second screen frame moves along with the second movable jaw, the first screen frame and the second screen frame are arranged in a suspension manner, the height of the first screen frame is larger than that of the second screen frame, and the secondscreen frame is used for bearing and screening the ore screened through the first screen frame. According to the crushing and screening integrated machine, through the arrangement of the two movable jaws and the two screen frames, secondary crushing and secondary screening of the ore are achieved, the screen frames are directly arranged at the lower portions of the movable jaws, a power device ofa vibrating screen is removed, and a crushing production line is further optimized.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, in particular to a crushing and screening integrated machine. Background technique [0002] In the prior art, the crushing operation and screening operation of the crushing production line are completed by two independent equipment, and a conveyor is used to connect the two to complete the mineral material transportation, which constitutes a part of the crushing production line. This layout leads to The result is: three equipments of crusher, conveyor and vibrating screen are needed, and the manufacturing cost, operating cost, maintenance cost and energy consumption are all high; 18°, if the angle is too large, the material will be dropped, and the crushing and screening equipment and its base have a certain height, so the length of each conveyor is 20-35m, resulting in a large area of ​​the entire crushing production line; the equipment must be pulled It is inconvenient to install and ...

[0002] In the prior art, the crushing operation and screening operation of the crushing production line are completed by two independent equipment, and a conveyor is used to connect the two to complete the mineral material transportation, which constitutes a part of the crushing production line. This layout leads to The result is: three equipments of crusher, conveyor and vibrating screen are needed, and the manufacturing cost, operating cost, maintenance cost and energy consumption are all high; 18°, if the angle is too large, the material will be dropped, and the crushing and screening equipment and its base have a certain height, so the length of each conveyor is 20-35m, resulting in a large area of ​​the entire crushing production line; the equipment must be pulled It is inconvenient to install and operate at a distance, which is not convenient for unified use and management; and the traditional jaw crusher is mostly used in the initial crushing station, and the particle size of the crushed mineral material is large, which cannot be screened or the screening effect is not good
