Crusher is the main equipment in stone production line. There are many kinds of crusher equipment on the market, each kind of crusher plays a different role in the stone crushing line. If the crushing equipment is selected properly, the production efficiency of the entire stone crushing plant will be greatly improved. So how to choose suitable crushing equipment for the stone crushing production line?
Generally speaking, a complete stone crushing plant production line needs to go through a series of technological processes, such as primary crushing, secondary crushing, fine crushing and screening. The following is a detailed introduction to the equipment selection of each crushing process.
Primary Crushing
In the rock crushing production line, the primary crushing is the first crushing. The first crushing equipment often used is jaw crusher and gyrating crusher. A general-scale sand and gravel plant will choose a jaw crusher as the first crushing equipment. Because jaw crushers' moderate price, applicable materials, output, feed, and discharge which can meet customer needs, so its application range is very wide. Customers with a larger scale of sand and gravel plants will choose the gyratory crusher as the first crushing equipment. The application range of gyratory crusher is relatively small because of its large volume, large weight, high output and high investment cost. The specific choice should be based on the actual needs of customers.
Secondary Crushing
In the stone crusher plant, the stone enters the crusher through the belt conveyor for secondary crushing after the first crushing by gyratory crusher or jaw crusher. Commonly used secondary crushing equipment includes cone crusher, impact crusher or hammer crusher. Among them, as the most widely used secondary crushing equipment, cone crusher has the biggest advantages that large output, low energy consumption, fine crushing particle size, uniform particle size, and long service life, so it has become the first choice of many quarry owners. The impact crusher and hammer crusher are more widely used because of their simple structure and low investment cost. For the rock with low hardness and brittleness, hammer crusher is the most suitable choice.
Each type of crusher has different advantages and disadvantages. Therefore, which crusher to choose as the second crushing machine needs to be combined with the customer's own requirements, such as crushing material properties, output size, discharge granularity, and investment budget. In terms of production efficiency and cost, cone crusher is more suitable for stones with higher hardness. Although the initial investment cost is higher, it can save a lot of operating costs in the long run.
Fine crushing and screening
In the process of gravel crushing production line, the stone material needs to be finely crushed and sieved after the first and second crushing. There are many types of fine crushing equipment, such as cone crusher, hammer crusher, vertical impact crusher, etc., which have fine crushing functions. The vertical impact crusher produced by Nile Machinery has obvious advantages for fine stone crushing and shaping of stone. There are many screening equipment in the market, such as circular vibrating screen, linear vibrating screen and so on. Nile Machinery can customize two-layer and three-layer vibrating screens according to customer needs, and the size range of the screening can be adjusted according to actual needs. For example, a circular vibrating screen is used to screen the materials completed by the second crushing. Generally, materials of 10mm or smaller can be screened and sent to the finished material area. After screening, the materials of 10-40mm enter some kind of fine crusher for fine crushing operation, and the materials of more than 40 mm are returned to the secondary crushing machine for re crushing through the conveyor belt.
Through the above process flow of the stone crushing production line, it can be found that each process can choose different crushing equipment to operate, including the subsequent screening equipment. Therefore, Nile Machinery reminds customers that they must choose according to their own needs, and don't be greedy for cheap crushers that are significantly lower than the market price. If you need to invest or build a sand and gravel production line and you are not sure which equipment to choose, you can contact us at any time. We will recommend more suitable equipment for you, and even design customized production line schemes to ensure that you can get greater benefits with the smallest investment.
