Difference between the jaw crusher and the hammer crusher

 

Jaw Crusher: It can process and crush more than 200 kinds of hard and soft stones. Generally, it is not used alone, but is often used as a preliminary crushing equipment, which can process raw materials with large block size (≤1200mm). It is often used in both crushing and sand making operations. The production capacity of large-scale jaw crushers can reach 1000t/h per hour, and the small-scale jaw crushers can be used for medium and fine crushing operations. Directly combine sand production with sand making mechanism.

Hammer crusher: It is a medium-sized crushing equipment that can be formed at one time. It mainly processes brittle stones with a compressive strength of not more than 150 MPa and medium hardness, and can crush various stones with a feeding particle size of not more than 1700 mm. If the user's budget is limited and the requirements for sand and gravel products are not strict, the hammer crusher can be used alone to form a crushed stone production line. The large hammer crusher has a production capacity of 3,000 tons per hour, and can also be used for stone sand production.

 

Hammer crushing relies on the impact, impact and crushing effect of a high-speed hammer to break stones. It is also equipped with a grate bar, and the crushed stones are discharged through the grate bar with a mesh size smaller than that of the sieve, while the coarse particles that pass through the sieve mesh must continue to be hit and broken by the hammer.

 

 

 

The jaw crusher relies on the moving jaw to move up and down temporally. When the moving jaw rises, the angle between the bracket and the moving jaw becomes larger, crushing the stones, the angle between the bracket and the moving jaw becomes smaller, and the moving jaw becomes smaller. Under the influence of the pull rod and spring, it leaves the constant jaw plate, but the broken stones are discharged from the lower mouth of the machine cavity to complete mass production.

 

 

 

There are three adjustment methods of jaw crusher, pad type, wedge block type and hydraulic cylinder type. The pad type and the wedge-shaped block type are more commonly used now. These two methods have their own shortcomings. The hydraulic cylinder type just combines the advantages of the first two methods. It is believed that with the continuous development and progress of the society, hydraulic pressure Cylinder type will be widely used.

 

The discharge adjustment method of the hammer crusher is relatively simple, which is realized by replacing the bottom sieve plate, which is more suitable for the crushing and discharging of the stone containing a certain amount of moisture.

 

 

The jaw crusher belongs to the first crushing equipment, which is one of the indispensable equipment in the large-scale crushing production line. It is often matched with the secondary crushing equipment to process materials. Hammer crusher belongs to one-time forming equipment, and its operating cost and production cost are relatively low.

 

These 2 types of stone crushers have their own advantages and handle different types of materials in different crushing production applications. Different construction environment requirements and production requirements determine whether to choose a hammer-type stone machine or a jaw-type stone machine. Therefore, there is no good or bad for the stone crusher, only whether it is suitable or not, whether it can meet the production standards of different users, and whether it can bring more production economy to customers!
