In recent years, transportation and road construction industry has been developing in a more and more quickly way. Recently, the Ministry of Railways raised 200 billion Yuan so that in railway construction the supports from the nation have been continuing to be powerful. As for road construction, it is very important to select the appropriate crusher and stone and sand production line. In the stone and sand production line, in order to increase the production efficiency, it often needs to form a complete set of crushing machines; while the traditional cone breaking machine cannot satisfy the current contradiction between supply of and demand for sand. For this reason, Zhengzhou Great Wall Heavy Industry Machinery Co., Ltdstrongly recommends you to apply hydraulic cone crusher machine in the stone manufacturing line.
And compared with other crushers, when used in the infrastructure construction and processing ...view middle of the document...
The crusher avoids the disadvantages of impact crusher like low average crushing ratio, large energy consumption, and fast abrasion of blow bar, impact plate and lining board.
3. Between-layer pressuring crushing and better finished product shape.
â€”â€”The crusher adopts between-layer pressuring crushing principle and suitable turning speed, not the traditional single particle crushing principle. The special crushing cavity can make the crusher crush materials selectively, thus the proportion of fine product and product of cubic shape is increased distinctly and product of lump size is decreased by a large extent.
4. Hydraulic protection and hydraulic cavity clearing, high automatization and less stopping production and repairing time.
â€”â€”Discharge opening is adjusted by hydraulic device and overload protection makes performance of the crusher increased by a large extent, maintenance and operation are easier, repairing time is shorter.; the bidirectional metal releasing hydraulic vat makes slab pass through crushing cavityï¼›the crusher can discharges material automatically when the hydraulic device works under the condition of iron passing and instantaneous overloading, thus there is no trouble of stopping the crusher to discharge material by hand.
