A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.
Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Crushing is the process of transferring a force amplified by mechanical advantage through a material made of molecules that bond together more strongly, and resist deformation more, than those in the material being crushed do. Crushing devices hold material between two parallel or tangent solid surfaces, and apply sufficient force to bring the surfaces together to generate enough energy within the material being crushed so that its molecules separate from (fracturing), or change alignment in relation to (deformation), each other. The earliest crushers were hand-held stones, where the weight of the stone provided a boost to muscle power, used against a stone anvil. Querns and mortars are types of these crushing devices.

Mining operations use crushers, commonly classified by the degree to which they fragment the starting material, with primary and secondary crushers handling coarse materials, and tertiary and quaternary crushers reducing ore particles to finer gradations. Each crusher is designed to work with a certain maximum size of raw material, and often delivers its output to a screening machine which sorts and directs the product for further processing. Typically, crushing stages are followed by milling stages if the materials need to be further reduced. Additionally rockbreakers are typically located next to a crusher to reduce oversize material too large for a crusher.

Crushers are used to reduce particle size enough so that the material can be processed into finer particles in a grinder. A typical processing line at a mine might consist of a crusher followed by a SAG mill followed by a ball mill. In this context, the SAG mill and ball mill are considered grinders rather than crushers.

In operation, the raw material (of various sizes) is usually delivered to the primary crusher's hopper by dump trucks, excavators or wheeled front-end loaders. A feeder device such as an apron feeder, conveyor or vibrating grid controls the rate at which this material enters the crusher, and often contains a preliminary screening device which allows smaller material to bypass the crusher itself, thus improving efficiency. Primary crushing reduces the large pieces to a size which can be handled by the downstream machinery.

Some crushers are mobile and can crush rocks as large as 60 inches. Primarily used in-pit at the mine face these units are able to move with the large infeed machines (mainly shovels) to increase the tonnage produced. In a mobile road operation, these crushed rocks are directly combined with concrete and asphalt which are then deposited on to a road surface. This removes the need for hauling over-sized material to a stationary crusher and then back to the road surface.

Become a professional Manager - Everyone who wants success should have the nature of a diligent, persevering, serious, and honest. What is reflected by the mirror of you? Did you behave as befits a really professional? Have you been following proper norms? Do you already know the rules of conduct?

As players of pool are subject to the norms of geometry, the entrepreneurs anywhere should be strict ground rules of professional conduct.

When talking about such professionalism Protocol written more and more people think on the procedures required in situations of "micro" very distinctive, such as selecting the form of fork to a junket or a polite way of introducing ourselves. However, there are rules that nature "macro" underlying all the guidelines for such things at the top. Understanding these rules allow an Executive can always behave worthy, both in situations as desired or not. What is called "The Golden Rule of Business" is a grammar rule which is very macro staple.

Concentrated attention
Each Executive had to learn was able to use its energies appropriately; don't throw it to things that are useless. You should concentrate on the things that actually become your assignment and not squander its attention on issues that are not relevant or activities that are not productive.

In the different levels of each other, in every organization there are things that can potentially grow the unproductive activities such as infidelity, envy, gossip, attitude or grudge-the grudge which is private. All that energy dispersed, in other words capable of making the course work to become ineffective.

Take an example of the case of an Assistant sales manager in a big company. People point fingers at the disadvantage in drawing up the reports of the sale or advised him in order to improve the ability of the management.

The Assistant Manager should respond to such comments as something personal. He treat his ego that plagued earlier with trying to gain sympathy and support from co-workers se-professions, among others with the utterance which underestimate the advantages actually belonged to him. He was throwing out a lot of energy by being that should not be and ignore what he was supposed to do: correcting the shortcomings of the implementation of its work. It means ignoring the opportunity of being able to show improved his performance, as should those who are truly professionals, who receive any criticism that is constructive and learn from it.

An Executive should focus directly on energy use to the actual implementation and not spend that energy to reactions that the emotional nature.

Another important aspect in this regard the need for concentration is the realization that in a professional environment, human relationships is also its nature should be professional. One of the greatest dangers arise when each person trying to build a relationship with the style of social intercourse. There is no harm in being warm, kinship and friendly, but clever executives will still be aware that the corporate environment is not golfing venues or a group meeting.

Let the Office in an atmosphere of social guidelines could be very pleasant, but this attitude to wither care with formality and professionalism-the very things necessary to achieve high standards in appearance, such as the business office where people are interconnected more as a friend than as a colleague. This means opening the door wide for the arrival of a serious problem. In the life of the company, the quality and productivity of work can be set because the employees assume each other first as a friend and colleague, as the latter.
