How To Increase The Capacity Of The Jaw Crusher

Do you want to know how to increase the capacity of the jaw crusher? This article we will discuss the impact of feeding methods on production capacity, taking Jaw Crush as an example.

Jaw crusher is generally a crushing device at the front end of the whole line, so its efficiency has a great influence on the production line. And feeding is the first step in stone crushing. Mastering certain feeding skills is essential for the entire production.

Strictly control the size of the feed, and no jamming or blockage occurs

The design size of the jaw crusher feed port has such a formula: feed port size=(1.1~1.25)*maximum particle size of raw materials.

Many users do not understand it, and always use the measured feed port size as the maximum feed size. Therefore, it is easy for the raw material to block the cavity if the raw material exceeds the prescribed large particle size. Although it is not blocked repeatedly, every time it is blocked, the equipment will not operate normally for a long time. Therefore, strictly controlling the particle size of the raw materials is one of the important prerequisites for ensuring the normal operation of the jaw crusher.

Strictly control the feeding amount to prevent clogging due to excessive

Since the working principle of jaw crusher is half-rhythmic work, if too much material is put in, the material will be too late to be broken. The broken materials cannot be eliminated in time, resulting in material jams. Therefore, material interruption and excessive feeding will affect the production capacity of the jaw crusher.

Adjust the angle of the feeder and make full use of the feeder’s screening function to achieve pre-screening

Vibrating feeders are often equipped with grate bars with some screening functions. However, in practical applications, due to the amplitude, feeding angle and other reasons, the equipment is prone to block jamming of the grate during the screening process.

In fact, when adjusted properly, the efficiency of the grate bar of the vibrating feeder is extremely obvious. Adjusting the amplitude, the angle of the jaw breaker, and fully releasing the sieving function of the feeder are the best ways to increase the total throughput.

Reasonably adjust the jaw crusher discharge opening and engagement angle

The size of the discharge opening of the jaw crusher determines the processing capacity of the equipment. The jaw crusher is often used as a coarse crushing equipment, and the size of its discharge port should be based on the optimal feed size of the second-stage crushing, and the size of the discharge port cannot be increased or reduced arbitrarily.

The adjustment of the engagement angle (the included angle between the movable jaw and the fixed jaw) needs to be strictly carried out, generally within the range of 17~26° (specifically subject to actual conditions).
