Principle and advantages of hammer crusher
The plate crusher is also called a jaw crusher, because the crushing principle of the jaw crusher is that two movable jaw plates simulate the movement of the animal’s two jaws to complete the material crushing operation, so it can also be called a plate crusher. The hammer crusher is so named because it mainly relies on the rotation of the hammer head in the crushing cavity to complete the material crushing operation.
1. The principle of crushing
The main working part of the hammer crusher is the hammer head. During operation, the high-speed rotating hammer head exerts impact and shearing force on the material. At the same time, the material will rush from the high-speed rotating hammer head to the inner baffle and screen bar of the machine. The sieve material is blocked on the sieve plate and continues to be broken until it is broken into the required particle size and then discharged from the sieve plate.
2. Applicable materials
The hammer crusher can be widely used for crushing various ores with compressive strength not exceeding 100MPa and moisture content less than 15%, such as cement, coal, coke, oil shale, chalk, limestone and other brittle, medium hardness and soft materials. Crushing and fine crushing processing.
3. Scope of use
The hammer crusher has a relatively small crushing ratio and is a medium to fine crushing equipment. It is mainly used in cement, mining, coal preparation, power generation, chemical and building materials departments, and is responsible for the secondary crushing or primary crushing of materials.
4. Feed and finished product size
The feed size of the hammer crusher is less than or equal to 1000mm, and the output size is between 10-90mm. It is formed at one time and does not need to be returned.
5. Model and output range
Hammer crushers can produce up to 3-3000 tons per hour. The types and models are mainly divided into two categories, namely PC hammer crushing and PCZ heavy hammer crushing. Among them, the performance of heavy hammer crushing is relatively good.
Jaw crusher is used for the primary crushing of high-grade materials in the production line. It usually needs to be used with secondary crushing equipment, cone crusher or impact crusher. Hammer crusher can be formed at one time, and usually can be used alone. In the actual production application, which equipment is better to use, it needs to be combined with the actual material characteristics that need to be crushed, the output size, the output size, the quality of the finished product, the investment budget, and the crushing process to comprehensively select and judge
