For highway construction, it is high requirments to grain shape and gradation of sand and concrete aggregate. Therefore, the famous mining machinery manufacturer in China, Red Star Co., has developed the matched sand making line accordingly. And the new processing line is high efficiency, low opreation costs, large production, reasonable finished product gragation, uniform particle size and good grain shape. The standard far exceeds the national high-speed material requirements.

Red Star launched the latest generation of broken machine, SDY cone crusher, which adopts the most advanced international crushing technology and manufacturing level . Compared to the traditional two-stage jaw crusher and impact crusher, this new type cone crusher shows its unparalleled superiority in service life and repair rate. Besides, as to the set of equiped machine cone crusher and stone shaping machine, SDY cone crusher is low cost.

In the crushing production processes, production efficiency has always been the concern to users and manufacturers. And the feed configuration directly decides the high efficiency of cone crusher. If the amount of feed material is properly and evenly covered in the crushing chamber, the cone crusher will be able to achieve maximum efficiency. We can take measures in advance to install the feed configuration by thoughtful checking installation map and cone crusher space size. The feed device should be easy to dismantle when mantainance. So, before final opreration, we shall make out the detailed and rational feed configuration to ensure the high efficiency in crushing production.

The consequences of incorrect feeding: 1. a lower production capacity, 2. defective particle size is too big 3, the adjustment ring shift is too large, 4. bearing pressure is larger, 5. larger power consumption. Therefore, the correct feeding way is good for both efficiency and maintenance of the machine.

 Feeding method: the right way of feeding should combine with sub reel of cone crusher. The feeder bins will help to ensure the well-mixed material being evenly distributed along the entire crushing chamber and ensure the segregation of fines and coarse material remains in the smallest degree to minimize liner wear. Whether the short head type or standard cone crusher, we had better do pre-screening to screen the compound of the fines and viscous materials. This will avoid problems such as material clogging, excessive movement of the adjustment ring and low production efficiency. We should also install a metal detector to get rid of the foreign metal object.
