Plate feeder Mainly divided into three types, heavy plate feeder,light plate feeder,middle-size plate feeder. The working process is divided into two parts: firstly, the dynamic is produced by motor and transited to connecting rod and ratchet wheel by reducer. Secondly, the dynamic prompts the connecting rod of eccentric device to reciprocate.

The design of the annular cooler is now essentially composed of a rigid ring frame construction for easy and sustainable material centering. The advanced design of the cooler charging chute ensures a more homogeneous distribution of the sinter onto the sinter cooler, keeping pieces with larger diameters near the bottom and the smaller at the top.
For San-Xin gold and copper mine, deep blasting large block rate is high resulting in difficulty in transporting the ore out; secondary blasting not only increases blasting costs but is more likely to cause the top and bottom plate of the underground to become loose causing safety hazards. Based on the research background of Sanxin …

The gold ores are usually big and have to be crushed to reduce them to a size of about 12mm diameter before pure gold can be extracted from them. The ore usually has to pass various crushing stages, each reducing the ore to a certain size. Crushing plant layout is of vital importance. Gold-containing rocks are crushed for several reasons.
