For a sand making production line, from raw materials to finished products, it generally has to go through three to four crushing and shaping processes, and in different crushing processes, it needs to be applied to different crushing equipment, and use the different characteristics of the equipment to play a role in the crushing production process. The following article will analyze and introduce the advantages and disadvantages of common crushing equipment from the three stages of coarse crushing, fine crushing and shaping.
　　
Coarse crushing stage:
  　　
In the sand making production line to get the coarse crushing stage, the general application equipment is: jaw crusher.
  　　
The jaw crusher is one of the most common crushing equipment in the sand making production line, responsible for the first step of processing the larger raw stones. Its advantages are simple structure design, easy maintenance, reliable performance during work, and the price is cheaper than other crushing equipment, and the most coarse crushing cost performance is extremely high. The disadvantage is that the liner of the equipment is easy to wear as a wearing part, and the discharge particle size is large, the needle content is more, the finished product cannot be used directly, and it must be further processed with other sand making equipment.
  　　
Medium and fine crushing stage:
  　　
The commonly used equipment in the middle and fine crushing stage of the sand making production line are: cone crusher and fine jaw crusher.
  　　
Cone crusher is the star product of medium and fine crushing stage, common models are single-cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher. The cone crusher has the advantages of good wear resistance, large crushing ratio, high efficiency and low consumption, stable quality of finished products, and good particle shape. However, there are also shortcomings, its structure is more complex, maintenance and replacement parts are more troublesome, and the single machine is expensive, and the initial investment cost is high.
  　　
Fine crushing stage:
  　　
If the production line does not have the requirements for sand making, the cone crusher and fine jaw crusher can already be used as the final fine crushing stage. However, if the product requirements are higher, it is necessary to equip a sand making machine, that is, a high-efficiency impact crusher.
  　　
Its advantage is that it can shape the sand and gravel, and the finished grain type obtained is good and the needle is less, which is the most common and widely used sand shaping equipment on the market. The disadvantage is that the equipment mechanism is complex, and the cost of repairing and replacing parts is high, and the particle size of the feed material is required.
