Most sand and gravel plants are equipped with a single production line, requiring several machines to work together. Recently, some users have asked whether the stones produced by a fine jaw crusher are usable. Can a single jaw crusher produce 12 or 13mm stones? Can a jaw crusher process these stones independently? Below, we will answer this question for you.

Can the stones produced by a fine jaw crusher be used?

Those familiar with the sand and gravel market know that jaw crushers are primarily primary crushers, renowned for their large feed opening, high output, strong compressive strength, and large crushing ratio. They are often combined with secondary crushing equipment (impact crushers or cone crushers) to form crushing production lines, and with tertiary crushing equipment (sand making machines) to form sand making production lines. These are well-known features. What users may not know is that it can also perform one-step crushing, breaking stones of a certain size into construction sand.

In fact, jaw crushers have evolved to three series: jaw crusher, HD German-style jaw crusher, and CJ jaw crusher. Jaw crushers are further divided into two series: coarse jaw crusher and fine jaw crusher. As the name suggests, coarse jaw crusher is the primary crushing equipment commonly found in multi-stage crushers, while fine jaw crusher is designed for crushing smaller stones. The finished product particles are much finer than those from coarse jaw crushers, and the crushed stones can be used directly, but the output is relatively low.

Can a jaw crusher produce 12mm and 13mm stones?

From the parameters above, we can see that its discharge port adjustment range is adjustable. The finished product particle size can be controlled by adjusting the discharge port range. Additionally, a screening machine can be installed downstream. The stones produced by the jaw crusher can be screened by the screening machine. On one hand, it can simultaneously screen out 12mm and 13mm stones, transporting them to the corresponding finished product stockpile; on the other hand, it can return stones that do not meet the particle size requirements to the fine jaw crusher.
