Comparison of Jaw Crusher and Impact Crusher

The demand for crushers is in creasing in the market, and its models and working methods are also diversified. Today, the ZKCORP has a simple comparison of jaw crushers and impact crushers to see how much you know.

The demand for crushers is in creasing in the market, and its models and working methods are also diversified. Today, the ZKCORP has a simple comparison of jaw crushers and impact crushers to see how much you know.

First, comparison of working principles

1. The working principle of the countercrusher

Impact crushers use impact energy to breakmaterial. When the material enters the impact area of the hammer, it collideswith the hammer (on the rotor driven by the motor) on the rotor rotating at ahigh speed, and then it is thrown on the counterattack device to be broken, andit is broken again by the rebounding hammer. Repeat until the material iscrushed to the desired particle size and exit the discharge port. Adjusting thegap between the counter-rack and the rotor can change the particle size of thematerial and the shape of the material.

2. Working principle of jaw crusher

A jaw crusher works like an animal chews onthe same principle, except that the crusher chews material that needs to becrushed. The motor drives the belt and the pulley. The eccentric shaft movesthe jaw up and down. When the jaw rises, the angle between the bracket and thejaw becomes larger, so that the jaw is approached to the fixed jaw, and thematerial is crushed at the same time smashing, to achieve the purpose ofcrushing. When the jaw is down, the angle between the elbow and the jaw becomessmaller, and the jaw is removed from the fixed jaw under the action of thespring and the pull rod, and the broken material is discharged from thecrushing cavity discharge.

Second, the application area comparison

1. Counter crusher crushing field

The counter crusher can handle variouscoarse, medium and fine materials (dolomite, granite, limestone, quartz stone,iron sulfide, concrete, etc.) with a side length of not more than 500mm and acompressive strength of not more than 350MPa, and is widely used in hydropower,highways, artificial gravel, broken and other industries. Its performance characteristics:unique structure, no key connection, high chromium plate hammer, a uniquecounterattack liner; hard rock crushing, high efficiency and energy saving;product shape is a cube, adjustable size of the discharge size, simplify thecrushing process.

2. Crushing field of jaw crusher

The movable jaws are reciprocated against thefixed jaws and crushed and rubbed, then separated and then approached. When thetwo seesaws are separated, the material immediately enters the crushingchamber. At this time, the finished product has been discharged from the bottomof the crusher. When the two sampan plates come together, the material enteringthe crushing chamber is subjected to two sampan plates. The pressing force ofthe pressing belt knead the material, thereby bending and crushing the materialand breaking the material. The entire process of breaking the material isrealized.
