Stone crusher is mainly used to crush stones into sand. With the increasing demand for aggregates of sand and gravel, with the development of science and technology, there are more and more types and models of large-scale stone crushers on the market, and the crushing effects of different specifications of equipment are not the same. At present, there are many models of large-scale stone crushers, such as jaw crusher, cone crusher, impact crusher and heavy hammer crusher. There are so many types, how do you know how to choose? How much can I buy? Is this a question in everyone's mind?
1. Primary crusher-jaw crusher (primary crushing)
The jaw crusher is simply referred to as jaw crusher, which is used for coarse crushing of materials. Its main advantages are: It is suitable for crushing materials with medium hardness and above. Compared with other crushers, the jaw crusher has a simple structure, convenient maintenance and low price. In addition, the output range of the jaw crusher is very wide, as small as 7t/h, up to 1500t/h, suitable for large, medium and small crushing lines. Therefore, the jaw crusher is currently the best-selling crusher on the market.
2. Secondary crusher- cone crusher, impact crusher (cone crusher, impact crusher: secondary and fine crushing)
Cone crusher is abbreviated as cone crusher. It has the advantages of large crushing ratio, low efficiency and low energy consumption, uniform product size, suitable for medium and fine crushing of various ores and rocks, and its light abrasion and less dust during work. The impact crusher is called impact crusher for short, which is mainly used for the next crushing (secondary crushing and fine crushing) of the jaw crusher. It is mainly suitable for the crushing of soft materials. The main advantage is that the crushing ratio is large, and the crushed material has a good particle shape, and it is more cube-shaped. Its discharge size can be adjusted, and it is a high-yield, low-consumption, structure-ordering equipment. Cone crushers are mostly used for crushing materials with relatively high hardness, generally used in large construction materials and mineral processing fields. Impact crushers are mostly used for materials with low hardness and good brittleness, and are mostly used in construction materials and construction industries. But both crushing capabilities are very strong, such as GPY single-cylinder cone crusher capacity up to 2188t/h, HPY multi-cylinder hydraulic cone crusher capacity up to 2388t/h, PFQ impact crusher capacity up to 1200t/h.
3. One-time molding-hammer crusher
The hammer crusher is abbreviated as hammer crushing, which is mainly used for medium and fine crushing of materials and layered crushing. Its advantages are: simple structure, easy operation, light equipment quality and convenient maintenance. The output of the hammer crusher can reach 2000t/h, which is suitable for the production line that does not have high requirements on the particle size of the finished product.
What determines the cost of large crushers?
1. Equipment output: the performance characteristics of each crusher, the output level are different, the customer should determine how much output needs to be achieved per hour according to their own needs, and let the manufacturer give a reasonable quotation.
2. The breadth of applicable materials: Crusher not only crushes one kind of material, one crusher can be applied to many materials, and the types of materials applicable to the crusher are more expensive than those with fewer materials.
3. The production technology used: production technology is a factor that affects the price, such as the principle of crushing, what is the installation system, and the level of configuration, etc. Once you understand these, you have a budget for the price of this equipment.
4. Feeding size: The size of the feeding size determines the size of the processing capacity. The larger the feeding size, the greater the processing capacity, and the price is relatively expensive.
