Hammer Crusher Vs Jaw Crusher

Different Working Principle

The principle of heavy hammer crusher is similar to that of an ordinary hammer crusher machine. It mainly relies on the impact, shearing, tearing of the rotating hammerhead, the mutual impact of materials and the impact of the liner to crush the materials.

Jaw crusheris a typical representative of crushing by squeezing. The crushing cavityof jaw crusher machineis composed of two jaw plates, a movable jaw and a static jaw, which simulates the movement of the two jaws of an animal to complete the material crushing.

Different Uses

Hammer crusher is mainly suitable for materials with medium hardness, such as limestone, bluestone, coal gangue, chalk, etc. And the particle size of the feeding material can reach more than 1 meter.

Jaw crusher is used for coarse crushing of various ores and bulk materials, especially suitable for crushing hard rock, granite, quartzite, pebble, iron ore, etc.

Different Discharge Adjustment

Many hammer crusher machines are not equipped with grate bars and the discharge of materials can be controlled by adjusting the gap between the hammerhead and the impact plate, which can reduce the material blockage rate.

The discharging particle size of jaw crushing plant can be adjusted by gasket, hydraulic or inclined iron adjusting device, among which gasket and hydraulic adjustment are common methods.

Different Structure and Wearing Parts

Hammer crusher is mainly composed of the casing, the rotor, the main shaft, lining plate and the striking plate, among which the hammer head on the rotor is the key vulnerable part.

The jaw crusher is composed of a frame, transmission mechanism, adjusting device, tension device, safety device, and lubrication system. The jaw plate is the main vulnerable part of the stone jaw crusher.

The main advantage of hammer crusher is that the crushing of low hardness ore can be formed at one time. For the production line with an hourly output of less than 300 tons, single hammer crusher plant can replace the configuration of the jaw crusher and impact crusher.

Jaw crusher has the advantages: simple structure, convenient maintenance, high wear resistance, high-cost performance, which is suitable for ore with various hardness. However, due to the high content of needles in the discharge of stone jaw crusher, it is necessary to cooperate with impact crusher for shaping.
