Development Trend of Sand Making Machine
At present most of impact crushers made in our country are imitative. Independently developed crushers are few. They start late and develop slowly. Products manufactured by all manufacturers are largely identical but with minor differences. Although there are advantages in the sales quantity on the market by virtue of price, there is gap in technology and quality compared with foreign advanced level: the service life of the quick-wear parts (material-discharging head, runner plate, material supporting plate, impact plate and impeller body) on domestic crushers is commonly shorter than that of foreign advanced products.
There is gap between domestic impact sand making machines and foreign large crushers. To shorten the gap, improving domestic technological level of impact sand making machines should take the following measures: owing to severe service condition of crushers, the working life of quick-wear parts is extremely critical. Therefore, processing technology of special materials should be introduced. We can stay on the conventional high-chromium iron, ultrahigh manganese steel levels such as inlaying of hard alloy, composite pouring and industrial ceramics etc.
Impact sand making machines with 3, 4 sections develop toward 2-section crusher, and approach the level of impact crusher and cone crusher. To improve domestic impact sand making machine, staying only on the basis of introduction and imitation is not enough. We should make innovation based on digestion and absorption. We must adopt modern design methods and vigorously launch experimental work such as flow condition of materials in impellers, abrasion rule of runner lining plate etc.
With the continuous progress and development of science and technology, economic construction has higher and higher requirements on industrial automation, and puts forward new requirements on operational skills and sand making machines. Sand making machines play a larger and larger role in national economic field. Nowadays, the competition of sand making machines is increasingly keen, and supermatic, intelligentized, multifunctional, efficient and low consumption mine equipment are more and more popular in the industry.
Further reducing production costs, management costs and increasing production efficiency make the third generation of sand making machines, including artificial sand making plant etc, achieve high quality and low price, further improving competitiveness of the market at home and abroad to expand increasingly competitive market in our country.
