The structure of the jaw crusher’s chamber affects the crushing performance of the jaw crusher. This article will teach you the improving methods of the jaw crusher’s crushing chamber to improve the crushing efficiency of the jaw crusher. Now let’s talk about it in detail.

1. Improve the shape of the crushing chamber to a steppe shape. The angle formed by the two faced jaw plates is smaller and smaller from the top to bottom. The working surfaces of the two jaw plates that locate in the lower of the crushing chamber is long narrow structure. So that the material feeding of ladder shape crushing chamber is very enough and level sets level, which greatly improve the crushing efficiency of the jaw crusher.

2. Improve the tooth structure of the working surfaces of the two jaws. The tooth height becomes gradually lower level by level, and the tooth width is gradually narrowed level by level, so that it can appear as tooth stepped structure. Materials are fed from the upper port and discharged from the lower port, and during this process, large materials are crushed by the big tooth structure device, while the small size of the materials are crushed by the small tooth structure device, so that materials are evenly fine crushed into small sizes.

3. The working surfaces of the two jaws that locate at the last level of the crushing chamber is strip-type structure. The range of the angle formed by the standoff is ± 5 °, and the width of the elongated structure working surface is 1-3 times of the size of the discharging material particles. Therefore, the particle size of materials discharged form each working cycle of the crushing chamber is controlled within the desired size range, and the improvements have achieved a uniform finely crushing, and improved the crushing efficiency of the jaw crusher.
