The Research and Development of Crushing Cavity of Compound Pendulum Jaw Crusher

As for the compound pendulum jaw crusher, the shape and size of the crushing chamber should satisfy the following four requirements: the quantity of the materials that go into the crushing cavity in unit time should not be more than that can be crushed and discharged; the materials should be distributed evenly in the crushing chamber; the crushed materials should be able to be smoothly discharged out of the crushing chamber; there should be a horizontal area on the bottom of the crushing cavity. The researchers of Hongxing Machinery do a lot of research and design on the crushing cavity of this jaw crusher.

With the establishment of the math model of the crushing process, precisely describing the crushing process has become a reality, for example, use the principle of statistics to research the crushing rule of the materials and establish the crushing matrix model; plus the popularity of the computer, establishing a model that is based on the actual operation of jaw crusher and conduct numerical calculation have been made possible and provided foundation for further simulation and optimization.

When examining the actual moving condition of the materials to be crushed inside the compound pendulum jaw crusher, the complicated swing property of the movable jaw should be considered. On the basis of the and flowing of the materials inside the crushing chamber and the movement property of all the points on the crushing teeth surface, the crushing chamber designed can be divided according to the shape of the fixed jaw and the movable jaw: linear-linear type, curve, linear-curve, linear type, curve, linear-linear type and linear-curve, linear type. The optimized designing of the crushing chamber can be optimized adopting the separated optimizing method.

Due to the establish of the supporting model of precisely describing the crushing process, the design of the crushing cavity is developing gradually toward high and deep cavity, and the blocking phenomenon is less and less.
