Sand casting crusher Wear parts are very common in China, such as jaw plate, high chromium plate hammer, crushing wall, rolling mortar wall and so on, because in the crusher equipment, as a relatively large wear-resistant castings, relatively precision is not very high, especially such as jaw plate, out of the finished product almost no lathe grinding, crushing wall, rolling mortar wall, Roller and so on is only part of the casting parts need lathe Grinding, it is particularly suitable for sand casting, because the sand casting jaw, high chromium plate hammer, crushing wall, rolling mortar wall, roller skin and so on these crushing equipment wear-resistant parts than other such as lost foam casting process products More durable more than 20%.
But the EPC casting has the dimension precision high, the processing allowance is small, the dry sand falls the sand to be convenient, the clean and grinding work quantity reduces more than 50%, saves the labor cost, therefore the vanishing mold casting price is relatively low. Sand Casting is one of the casting process, the mold used in sand casting is generally composed of sand type and core. Because the molding material used in sand casting is cheap and easy to produce, the mold is easy to manufacture, it can adapt to the single piece production, batch production and mass production of castings, which has long been the basic process in foundry production.
At present, internationally, in all castings production, 60~70% castings are produced by sand, and about 70% of them are produced with clay sand. The main reasons are as follows: The sand casting method has the advantages of low cost, simple production process and short production cycle compared with other casting methods. So like the engine cylinder block, cylinder head, crankshaft and other castings are made of clay wet sand process production. When the wet type can not meet the requirements of the use of clay sand table dry sand type, dry sand or other sand type. The casting weight of clay wet sand castings can be from a few kilograms up to dozens of kg, while the clay dry type castings can weigh up to dozens of tonnes. Because of the advantages of sand casting, it is more and more widely used in foundry industry.
In the future, it will play an increasingly important role in the foundry industry.
