Double-motor-driven simple pendulum type planar motion vibration crusher and parameter determination method

Abstract

The invention discloses a double-motor-driven simple pendulum type planar motion vibration crusher and a parameter determination method. In a vibration system, a plastid is connected with a rack through a vibration isolation spring; two vibration exciters which rotate reversely are installed on a pendulum, each vibration exciter is provided with an eccentric rotor, and the eccentric rotors are driven by respective induction motors and rotate around the center of a rotation axis at a high speed, so that the plane motion function of the equipment is achieved; the vibration exciters and the pendulum jointly form a pendulum bob, the mass and the pendulum bob are connected through a torsion spring, the pendulum bob can swing around a connecting point in a reciprocating mode, materials between the pendulum bob and the mass are extruded and collided in the swinging process of the pendulum bob, and the crushing function is achieved. By establishing a kinetic model and a motion differential equation, solving the motion response of the system, deducing a synchronism condition and a stability condition and performing numerical simulation verification, the working efficiency of the vibration system can be effectively improved, and the working quality of the equipment can be improved. The crusher is particularly suitable for crushing high-hardness brittle materials and construction wastes.

Description

[0001] field of invention [0002] The invention belongs to the technical field of vibratory crushing devices, and relates to a two-machine driven single pendulum planar motion vibratory crusher and a parameter determination method thereof. Background technique [0003] With the rapid development of our country's economy and the mining and utilization of mineral resources, we are facing the dilemma of depletion of high-quality mineral resources, and with the current development level, it is difficult to use low-quality mineral resources economically and efficiently. Therefore, recycling and utilization of various mineral resources The need to develop technological advances is becoming more and more urgent. [0004] At the same time, with the expansion of resource development and utilization, my country needs to process a large number of refractory materials such as high hardness, brittleness and special structure every year. Taking steel slag in metallurgical slag as an examp...
