Cone Crushers

Wednesday, 30. July 2014

Cone crushers are widely used around the world. Crushers of this kind, produced in Russia are among the best, as adapted to the peculiarities of our climate. They have high abrasion resistance and, if necessary, they are always easy to find all the parts at very affordable prices can not be said of the equipment are imported. Cone crushers are used at all stages of crushing the processing of most variety of ores and materials, such as by size crushability material and the diversity of physical and mechanical properties. Except, perhaps, should be considered only materials having structure or containing clay fraction at high humidity.

In the first case can occur overload the driving motor grinder or an increase in size crushability material in the second – frequent operation of the system and amortization clogging of the crushing chamber. Classification of cone crushers, depending on the destination as follows: sac – boulder crusher; dcc – secondary crushing mills; kmd – crushers tertiary crushing; mrc – crushers reducing fragmentation. The crusher ksd and cmd main characteristic is the diameter of the rolling cone, which is in production of industrial sizes of crushers is 600 – 3000 mm. In crushers process fragmentation is the compression of material between the two cones, placed one inside another. The first samples of such machines have a workspace in the form of two truncated conical surfaces, from whence they name – the cone. Workspace modern cone crushers produced more complex surfaces are often curved shape.

Types of cable produktsiiKabelem called a device consisting of one or more cores enclosed in a metal or non-metallic shell, over which may be subject to a protective cover, including armor. In the presence of armored cable is called armored shell. Cables without the armored shell are classified as naked. Conductor – a device is not an isolated one, or one or more cores that are protected Non-metallic coil or braided fibrous materials or wires. Cord is a kind of wire and consists of two or more insulated flexible or very flexible live wires up to 1,5 mm twisted or laid parallel. Superimposed on top of live non-metallic shell and a protective cover.

Types kabeleyV depending on the application, the cables are divided into several groups. Power cable designed for transmission and distribution of electric power in stationary installations. For the production of live use copper or aluminum wire, insulation made of paper tapes impregnated with oil or special structures, as well as pvc plastic, polyethylene, crosslinked polyethylene, rubber. Shells can be lead, aluminum or plastic. Range of ac voltage, which uses power cables ranging from 660 to 500 kV. Communication cable is wired to the organization and signaling. Communication cables are divided into high (cable telecommunications) and low frequency (a local cable connection). Veins cables made from copper, insulation – made from paper, polyethylene, pvc plastic or a combination (air-and-paper or air-PE). Sheath cable connection can be leaden, aluminum, steel, plastic or metalloplastmassovymi. Control Cables used for connection of electrical appliances and devices, control of objects, alarms and other conductors made of copper, aluminum, bimetal copper and aluminum.
