The size requirement of the primary rock crusher is a function of grizzly openings, ore chute configuration, required throughput, ore moisture, and other factors. Usually, primary crushers are sized by the ability to accept the largest expected ore fragment. Jaw crushers are usually preferred as primary crushers in small installations due to the inherent mechanical simplicity and ease of operation of these machines. Additionally, jaw crushers wearing parts are relatively uncomplicated castings and tend to cost less per unit weight of metal than more complicated gyratory crusher castings. The primary crusher must be designed so that adequate surge capacity is present beneath the crusher. An ore stockpile after primary crushing is desirable but is not always possible to include in a compact design.
Many times the single heaviest equipment item in the entire plant is the primary crusher mainframe. The ability to transport the crusher main frame sometimes limits crusher size, particularly in remote locations having limited accessibility.
In a smaller installation, the crushing plant should be designed with the minimum number of required equipment items. Usually, a crushing plant that can process 1000s of metric tons per operating day will consist of a single primary crusher, a single screen, a single secondary cone crusher, and associated conveyor belts. The discharge from both primary and secondary crushers is directed to the screen. Screen oversize serves as feed to the secondary crusher while screen undersize is the finished product. For throughputs of 500 to 1,000 metric tons per operating day (usually 2 shifts), a closed circuit tertiary cone crusher is usually added to the crushing circuit outlined above. This approach, with the addition of a duplicate screen associated with the tertiary cone crusher, has proven to be effective even on ores having relatively high moisture contents. Provided screen decks are correctly selected, the moist fine material in the incoming ore tends to be removed in the screening stages and therefore does not enter into subsequent crushing units.
All crusher cavities and major ore transfer points should be equipped with a jib-type crane or hydraulic rock tongs to facilitate the removal of chokes. In addition, secondary crushers must be protected from tramp iron by suspended magnets or magnetic head pulleys. The location of these magnets should be such that recycling of magnetic material back into the system is not possible.
Crushing plants for the tonnages indicated may be considered to be standardized. It is not prudent to spend money researching crusher abrasion indices or determining operating kilowatt consumptions for the required particle size reduction in a proposed small crushing plant. Crushing installations usually are operated to produce the required mill tonnage at a specified size distribution under conditions of varying ore hardness by the variation of the number of operating hours per day. It is normal practice to generously size a small crushing plant so that the daily design crushing tonnage can be produced in one, or at most two, operating shifts per working day.

The development and utilization of mineral resources plays an enormous part in the development of social economy. It accounts for a large proportion in national economy. In particular, gold reserve is an important means for a state to stabilize the national economy, curb inflation and improve the international credit. Gold is not only the important manifestation form of universal money, but also widely applied in science and technology and the industrial sectors. We can see from the recent stock market that the gold market has grown by leaps and bounds. As a consequence, gold ore mining also become a sweet pastry in the field of mineral exploration. As the primary processing equipment of gold ores, gold ore impact crusher exerts a crucial role at the early stage of beneficiation process.

There is no metal in the world that can intervene in human economic life like gold, and have such a major impact on human society. Its dazzling luster and unparalleled physical and chemical properties have a magical eternal charm. Although the social status of gold has experienced vicissitudes, ups and downs, and ups and downs in the history of human civilization for thousands of years. But so far, it still maintains a sacred aura among many people, the wealth that the world seeks together.
The process of gold ore processing and production mainly includes three processes: crushing, grinding and beneficiation.In the crushing process, the three-stage closed-circuit crushing is more modern and suitable for high-hardness gold ore crushing, which can complete the work of ore crushing and partial dissociation, thereby improving the subsequent grinding efficiency;In the grinding process, the second stage and one closed grinding is an efficient grinding process, which can make the gold ore grinding more fully;Among the beneficiation processes, the representative new processes that have emerged in recent years mainly include: gravity separation, amalgamation, cyanidation, flotation, etc.
