Stone Crusher startup and normal operation: Confirm bore no material crusher to open after the start sequence followed by dust collector, discharging belt conveyor, crusher, belt conveyor feed, feeder and more. Mediation feeder to quantity, from small to large slowly increased, the material should be controlled as usual in the height of the jaw jaw bore bore a high degree of four-fifths of the feed should also be valued less than the maximum size pieces into the four-fifths of the width of the mouth, into the continuous and uniform particle size, crushing machine to play its best talent normally listen to. Beware of the items or parts falling steel breaker, a conditional time, the feed conveyor can be detected on the settled iron device. Check the SKF bearing operating temperature is usually, prefer SKF bearing temperature of more than sixty degrees. The material should be checked in operation size pieces, such as exceeding the prescribed mediation should stop the width of the discharge port. Downtime, material flow direction should be followed by parking along both the feeder, feed conveyor, crusher, the material delivery machine, dust collector, should be used and the composite crusher no material configuration, or again start time difficult. Check whether all configuration after stopping prejudice. Good operating records.
Jaw Stone Crusher application scope is wide, large, medium and small concentrator can be selected. Jaw Crusher The main advantage; simple structure, light weight, low cost, ease of maintenance and transport, the appearance height of a small, less need for plant height; In the process, its work, reliable, easy to adjust the port of discharge, broken wet containing clay minerals and ore and more difficult to jam. The main drawback is: liner easy to wear, handle than the gyratory crusher is low, too large particle size and more uneven, and require even to mine, to be set to the mining equipment.
Metal ore mining concentrator is generally handled by a hard or medium hard ore, suitable for use jaw crusher or gyratory crusher; in some non-metallic mineral or cement industry, when dealing with the hard or soft ore, we also Impact Crusher can be used.
Gyratory Crusher is a high breaking capacity of the equipment, mainly for medium-sized processing plant. Compared with jaw crusher, the main advantages: large capacity, in the same row of ore to the mine mouth and the mouth width, the handling capacity of the jaw crusher is 2.5-3.0 times; power consumption less; crushing chamber lined Plate wear uniform, uniform particle size; specifications of more than 900mm gyratory crusher can be packed to the mine, no to the mining equipment. The main drawback is: the more complex device structures, equipment, heavy, require a solid foundation, the body, requiring a higher plant.
For medium and large mineral processing plant, in determining the use of jaw crusher or gyratory crusher before, the general should be the total weight of equipment, installation of power, infrastructure investment, operating expenses, equipment configuration and process operation in areas such as technical and economic advantages and disadvantages of comparison, based on merit .
Currently manufactured and used in the production of maximum size of jaw crusher is 1500mm 2100mm, maximum size of gyratory crusher as 1400mm/220mm. Shenyang Heavy Machinery Plant Company introduced the United States Fuller gyratory crusher technology, large size is 1829mm. Many foreign manufacturers of jaw and gyratory crusher, and its structural parameters, technical performance is different, should be based on actual production data and information on manufacturers to choose.
Gyratory Stone Crusher made of ordinary type and the points of light, light is generally used to crush limestone, such as hardness is not high, density is not the ore. In addition, there are two special conditions for use of the jaw crusher and gyratory crusher. One is the disintegration of large lifting the crusher can be applied to underground mine pit crushing operations; other fixed or semi-mobile crushing machines, suitable for underground mine pit crushing operations; the other semi-fixed or mobile crusher is suitable for open pit mining, the location of regular or irregular movement of rock or ore crushing operations.
