Advantages of the old-style fine crushed jaw crusher after technical transformation: 2. The angle of the teeth changes from zero to a negative value, so that the material will not only be blocked, but it will form a longer “equilibrium zone†with the linear moving plate. The effective length is 30-60mm, which makes the discharge material parallel for a period of time. Extrusion (grinding) pressure, further thinning the material, and strengthening the discharge, the material to the bottom of the discharge area, the opening of the crushing chamber is increased, the discharge is accelerated, and the blockage defect of the discharge is fundamentally eliminated, and the discharge is improved. The output. 3. In order to ensure the number of extrusions in the material crushing chamber and increase the crushing ratio, the technology appropriately raises the height of the crushing chamber to form a so-called "high-depth" crushing chamber; and in order to increase the output, a new eccentric shaft speed is derived. The formula, the eccentric shaft speed of the patented product, can reach 330-350 rpm. This increases the number of swings, which not only enhances the crushing effect, but also increases the machine output. 4. The wear law of the composite pendulum jaw crusher is generally that the fixed jaw plate wears faster in the upper part of the discharge area. For this reason, the technology will make the fixed plate into a “straight line-corrected Gaussian curve typeâ€. This innovative design has achieved excellent results. Practice has proved that it has improved the wear of the jaws of the crusher and is made of a new alloy material, which has improved its life by more than 2-3 times.

1. Adopted Professor Dai Shaosheng's “fixed volume†straight line—corrected the Gaussian curve high-depth crushing cavity, so that the material received a certain degree of “lamination and crushing†in the crushing cavity, and the pure pressure crushing effect was five times that of the shearing. Stress, the material is subjected to multiple lamination and pulverization in the crushing chamber, so the machine crushing effect is significantly improved, the crushing efficiency is high and the average particle size of the discharge can reach 5-10mm.
