Differences between jaw crusher and hammer crusher

With the continuous development of the mining industry, the crushing equipment has also obtained greater development space, and various types of crushing equipment have been developed, among which the most commonly used are jaw crushers and hammer crushers. So, what is the difference between these two crushers? Which is better to use? Let's take a look.

I.   The difference between jaw crusher and hammer crusher

1. Differences in working principles

The main crushing components of jaw crusher are two jaw plates. During operation, the movable jaw repeatedly approaches and leaves the fixed jaw, and exerts multiple crushing forces on the material to make the material smaller until it meets the requirements and discharges to complete the crushing.

The main crushing component of the hammer crusher is the hammer head. During the hammering operation, the high-speed rotating rotor drives the hammer to continuously hit and cut the material, so as to achieve the purpose of crushing the material.

2. The difference between applicable materials

The jaw crusher has a wider range of applications and is suitable for crushing various materials whose compressive strength does not exceed 350MPa.

Hammer crusher is mainly suitable for crushing materials with compressive strength less than 200MPa and moisture content less than 15%, such as cement, coal, coke, limestone, etc.

3. The difference between the particle size of incoming and outgoing materials

The jaw crusher has a feed size range of 125-1200mm and a discharge size range of 10-300mm, which is mainly used for coarse crushing of materials.

The feeding particle size of the hammer crusher cannot exceed 1200mm, and the output particle size range is between 10-90mm. It can "one-hammer forming" the material. One hammer crusher is equivalent to jaw crusher + counterattack crusher, combining two crushers into one crusher. , more energy saving.

II.   Which one is better, jaw crusher or hammer crusher?

The jaw crusher is often used together with the secondary and tertiary crushing equipment in the production line. It is a coarse crusher for stone materials; the hammer crusher can be used alone and can achieve one-time crushing. Therefore, it cannot be said which equipment is better to use, but which equipment is more suitable for your stone production line. Whether it is suitable or not is mainly from the aspects of crushed materials, production line scale, application method, etc.

If you are crushing materials with high hardness such as granite, quartz stone, iron ore, etc., it is recommended to choose a jaw crusher; if you are crushing materials with low hardness such as limestone and coal gangue, it is recommended to choose a hammer crusher.

If your work site is small, it is recommended to choose a hammer crusher, which can be crushed at one time. It only needs to be matched with auxiliary equipment such as a feeder to form a production line, which covers a relatively small area; and a jaw crusher needs to be matched with medium, which will occupy a relatively large area when configured.

In short, when choosing equipment, you must be clear about your own needs and the actual operation situation, in order to choose suitable equipment, build a suitable crushing production line, achieve better operation results, and bring higher economic benefits to the enterprise.
