Advantages of the Jaw Crusher’s Long and Narrow Type Crushing Chamber

Aug 07 2014

According to the improving analysis of the jaw crusher, the paper presents a long and narrow type of crushing chamber. That is to say change the old structure of the crushing chamber into the stepped ladder structure, and design the structure of the working surfaces of the two jaws as long and narrow type structure. What advantages does this type crushing chamber have? I will explain to you below.

1. The long and narrow type crushing chamber regards the state of the tight side as the standard. The range of the angle between the two jaws is ±5. when choose negative angle, it is conducive to discharge; while choose the positive angle, it is in favor of crushing, and when choose zero angle, the discharge of materials is the most even.

2. The length of the crushing chamber’s transverse cross-section is long, while its width is narrow. The depth in the crushing direction is deep. The connection precision of the materials and jaws is high, which is more conducive for crushing materials.

3. The long and narrow crushing chamber has the characteristics of "little tight side, big stroke," so that its occlusal state is better, and the particle size of the crushed material is uniform.

4. The long and narrow crushing chamber is conducive to realize laminated crushing mechanism so that the big size materials can be directly crushed. It achieves the beat crushing result with the simplest tools.
