C-series European type jaw crusher

Abstract

The invention belongs to the field of jaw crushers, and particularly relates to a C-series European type jaw crusher. The C-series European type jaw crusher comprises a fixed jaw plate, a movable jaw, a movable jaw plate and a toggle plate. The included angle between the fixed jaw plate and the movable jaw plate is the engaging angle alpha, and the included angle between the movable jaw and the toggle plate is the transmission angle beta, wherein the engaging angle alpha ranges from 20.6 degrees to 23.6 degrees, and the transmission angle beta ranges from 46.9 degrees to 49.9 degrees. The engaging angle and the transmission angle of an existing traditional C-series European type jaw crusher are reduced at the same time and are reasonably matched, the up-down oscillation amplitude of the movable jaw can be reasonably increased, and the left-right oscillation amplitude of the movable jaw can be reasonably reduced; under the situation that the motor rotating speed of the traditional series of crusher is increased by 30%, the crushing effect can still be guaranteed, and the phenomenon of material spitting or blocking does not happen; and meanwhile, the yield can be increased by 30% or above, the traditional technicist concept is broken through, and a large difference exists between the C-series European type jaw crusher and the current series of crusher equipment in performance.

Description

technical field [0001] The invention relates to a C series European-style jaw crusher, which belongs to the field of jaw crushers. Background technique [0002] Jaw crusher is a commonly used crushing equipment at present, which can crush raw materials such as stones of different sizes into small pieces with uniform particles. Among them, the C series European jaw crusher has relatively better crushing effect. Its working principle is as follows. Raw materials continuously fall into the crushing chamber composed of fixed jaw plate, movable jaw plate and side guard plate from the upper end, and the motor drives the pulley to drive the eccentric shaft. Rotate to transmit the power to the movable jaw, and drive the movable jaw on the movable jaw to approach and leave the fixed jaw periodically. When the movable jaw rises, the angle between the toggle plate and the movable jaw (that is, the transmission angle) becomes larger. In this way, the movable jaw plate is pushed close t...

Problems solved by technology

[0003] However, in the actual application of the C series European jaw crusher, if you want to ensure the crushing effect of raw materials and improve the crushing efficiency, you need to increase the speed of the motor that drives the pulley, but if the speed continues to increase, there will be a situation of spit. That is to say, the raw material will jump up during the crushing process (up to the upper end of the crushing cavity), but the problem of material discharge has not been solved, so the current maximum speed of the motor can only be controlled at 230r / min, and the crushing effect is difficult to obtain improve
