crusher main usage and performance features introduced

Crusher as viewed from the structure, some as hammer crusher, but there are many important differences: Crusher hammerhead rigidly fixed to the rotor, broken rotor time to take advantage of the energy is conducive to breaking big block material; have counter devices and larger crushing chamber, broken only by the hammer of material impact, but also with the back plate using materials and materials in the crushing impact of the collision between the cavity; broken does not grate on the bottom, broken granularity of the product from the back plate and hammer the gap between the decision, they were able to avoid the wet material clogging the phenomenon of grate bars, the advantages of this crusher:! be broken by the impact, so that the object along the fragile surface of fragmentation, crushing, high efficiency, less energy consumption, production, particle size uniformity; 'broken screen than the shock, simple structure, convenient manufacture; selective crushing the features that the density of materials broken particle size is small, the density of small particles of material broken degree.

Material than is usually broken by the largest diameter before breaking with the broken material in the ratio of the maximum particle diameter, said. Crushing the material mainly by mechanical methods. By the rotor hammer crusher is divided into the number of single rotor and double rotor types. In the coal preparation plant for crushing of large, hammer crusher is the use of high-speed rotary hammer blow to the role of the broken. Broken in the closed system, breaking through the screen to check the product, then the screen return to the coal crusher, until through the sieve so far. Featured the coal particle size machine can handle a certain range, beyond this range can be large to go through the broken washing.

The most common case is returned to the primary election in the coal-crushing machine to 13mm or 6mm following, and then into the re-election re-election machine. Crusher hammer main disadvantage is that wear faster, and more dust. The main disadvantage is the high moisture material easy to plug the grate; hammer and grate wear fairly quickly; In addition, if the rotor is not balanced, high-speed rotation when the harmful vibration; If the hammer does not meet the requirements of combat balance , will also produce harmful forces, extra energy consumption and reduce bearing life.

Crushing operations can also be based on their position in the production system for crushing and finally broken into. Some coal is a mixture of coal and waste rock symbiotic partings of coal, in order to choose the coal, it needs to be broken into smaller size, grading machine, stone machine prices, cement, coal and machinery to separate waste rock. The river system of the sand gravel materials cracking machine blocks the processing of small particles called broken, called for the crushing machine, crusher, or screening plant at the coal preparation plant, such as the crushing operation has the following purposes:

Meet the requirements of selected size. Commonly used in Coal Impact Crusher is mainly medium and small. What kind of crushing materials used mainly crusher broken manner, you need based on the physical and mechanical properties of materials, particle size and the required reduction ratio to decide. Preparing the next crushing operational requirements for the granularity of the fragmentation of the job; eventually broken is broken into the commercial coal coal particle size of the job requirements.

Impact Crusher is broken by the impact of the role of the machine. Compared with other types of crusher, hammer crusher has the advantage of simple structure, a single cement production equipment, compact structure, production capacity, and power consumption reduction ratio and less.

There are simple swing Crusher and complexity of the swing are two types of crusher. Impact Crusher can be used as materials coarse, medium, small and fragmented, can be used in coal and coal in the coal preparation plant in crushing the coal. Crusher has the advantage of reliable, capable of crushing hard materials. Roll Crusher is split pieces dominated, the role of both impact and bending the crusher.

Size to meet user requirements, the products or coal broken after the election to a certain size. According to the granularity of broken products, crushing operations can be divided into coarse pieces (the material crushing to 50mm and above), the broken (broken into the 25mm-6mm), small and fragmented (broken into 6mm-1mm), crushed (1mm or less). In a variety of crushing machine, often the main way is a broken, accompanied by other broken way.

Impact Crusher is mainly compression methods, both bending, impact and grinding effect of stripping the broken machinery. Coal crushing operations, there are two systems: open systems and closed-circuit breaking system broken, broken system is used for breaking open the product's size is not strictly required, or broken when the situation does not produce too large, closed-circuit crushing and milling system device called the loop broken system for broken products must be strictly less than the specified size to ensure that, while the broken machine itself can not meet this requirement of the situation. Single-rotor hammer crusher type is divided into reversible and irreversible two.

The disadvantage is due to intermittent work, discharge weight, so the processing power is low; broken coal, the coal than the teeth roll crusher and more. The disadvantage is that roller tooth wear, hard materials can not be broken, productivity is low. Crusher for waste rock hard or content of large number of coal pyrite broken. Coal use more single-rotor hammer crusher. Preparation for use with a single and double-Roll Crusher Roll Crusher Two, Roll Crusher has the advantage of a small degree of fragmentation products, powder, power consumption low. Suitable for crushing brittle materials can be broken into the coal (13mm-3mm) below, but also to ensure that the product is not mixed with large size of the particles in the coal preparation plant in the medium used for breaking and crushing operations. Coal in the use of open-circuit breaking system.
