Choosing a JAW CRUSHER

When choosing a JAW CRUSHER, you need to consider several factors. These factors include: Adjustable crusher settings, crushing chamber size, Jaw movement mechanism, and feed material. You’ll also need to think about how to feed coarse and fine materials to a jaw crusher. Learn more about jaw crushers here!

Adjustable crusher settings

Adjustable crusher settings for jaw crushers can be crucial for producing the proper particle size distribution. The final particle size will depend on the type of material and the crusher settings. Smaller jaw crusher settings will produce a higher proportion of elongated particles than larger ones. This can result in bridging problems in downstream machines.

Jaw crushers are constructed with stainless steel housings. The moving jaw and the eccentric shaft are made of high-grade forged steel, while the toggle is made of cast or welded steel. The toggle is held in place by a compression spring and is adjustable. Jaw crushers may be single or double-toggle. Single-toggle jaw crushers usually have fewer shafts and bearings.

Crushing chamber size

When selecting a jaw crusher, it is important to consider the crushing chamber size. This factor will determine the size of the finished product. Crushing chamber size is important for a variety of reasons, including the material’s hardness and the amount of material to be crushed. It also affects the efficiency of the crusher, which is the ratio of energy required by the machine to the amount of work done.

The operating geometry of a jaw crusher is generally nearly parallel. However, the angle between the two jaws can be increased or decreased. The resulting size is known as the compression ratio, and it is related to the capacity of the jaw crusher. It is also important to consider the size of the feed material.

Jaw movement mechanism

The movement mechanism of a jaw crusher works by compressing and releasing a fixed jaw. The jaws are then driven by an eccentric shaft and controlled by a toggle plate and spring. The movable jaw then moves back toward the fixed jaw and crushes the feed material. The resulting product is then discharged through the bottom opening.

The size of the crushed particles is controlled by the size of the gap between the moving and fixed jaw plates. This gap is known as the closed side setting (CSS), and it generally measures the distance between the peak of one jaw plate and the trough of the other.

Feeding coarse and fine material to a jaw crusher

A jaw crusher is a comminution machine that uses jaws to crush rock. The jaws have a wide range of capacities and are available in different sizes. The capacity of a jaw crusher depends on the type of rock and its moisture content, as well as the area of the discharge opening.

Jaw crushers typically choke feed their feed materials to maximize production capacity. Choke feeding ensures uniform particle size reduction and promotes stone-on-stone crushing, which breaks up flaky particles. However, feeding coarse and fine materials to a jaw crusher using a trickle feeder will reduce output and reduce wear life.
