Domestic large screening machine reaches advanced level
In the development of mining industry, in order to make technical management more convenient for and improve overall economic efficiency, different countries are increasing large-scale concentrator, coal preparation plant and quarry, construction project, therefore, the development of large-scale screening machinery is increasingly urgent. Germany on the basis of small and medium-sized screening machine developed a large-scale screening machine with maximum width of the screening machine for 5.5 m and length of l0 m and screening area of 55m2. SCHENCK (SCHENCK) Company manufactured a coke screening machine with 4m width, 8.5m length, covering an area of 34m2 , the processing capacity is of 800mz / h . KHD produced a 3.6m-width USI-screening machine, which has been used in many countries. Japan Kobelco developed the HLW screening machine, the maximum size is 3.6m 7.5m. Area is 27mz, has been used for many years in our country.
Sand Production Line, also known as sand making line, is mainly composed of jaw crusher, vertical shaft impact crusher (sand making machine), vibrating screen, sand washing machine and conveyor belt. Sand making machine is a new type of crusher unique combining the principle of "PL" and "PLST", which makes the sand making production line more efficient and less costly. Considering the situation of the decreasing natural sand, Hongxing Group has developed series of sand making machine which are dedicated to the production of artificial sand, and the machine has the characteristics of good grain shape, little attrition, high into the sand, adjustable fineness modulus, low cost, etc. Sand making machine is more suitable for crushing materials of high hardness such as Granite, Basalt and so on.China do a lot of work in the development of large-scale screening machine to for mining and stone screening, producing a2.1m width, 5m length, 12m2 Screening area machine. Maximum specifications for screening sinter cold mine sieve is 3m 9ni. Maximum sieve for Coal grading is with width of 3m, a length of 5.25m, area 16mz. Maximum dehydration de-referral screening, manufacturing width is 3. 6m, length 7. 5m, with an area of 27m linear vibrating sieve.
In order to accelerate the development of screening technology and screening machinery, from the 1950s to the 1960s in the former Soviet Union and Poland, we introduces various screening machine, improve our level of screening technology. The introduction of Japanese household system helps the HLW-type vibrating screen technology, the main horizontal mounting linear shaker. This sieve can also be changed to tilt installed Vibrating screen, six kinds of specifications, the maximum size is of 3. 6m x 7 - 5m, area 27mz, is a large-scale screening machine.
