Problems:
1. Dry low efficiency, butt unusually severe, resulting in production costs and enormous waste of resources;
2. Hammer Crusher crushing capacity is limited, can not provide a good Dry feeding machine, hammer wear very serious, 3 days to go for a hammer;
3. Jaw Crusher did not play its due function, make no use of electricity without the formation of effective crushing operations;
4. Crushing process layout is unreasonable, there are a lot of material handling work, engineering machinery consume a large amount of production costs;
Analysis:
1. Dry low efficiency, butt unusually severe, resulting in cost and enormous waste of resources;
Selections are generally adopted the open-loop design (not set back to the broken material), into the dry granular material sorting machine is not under control, after a lot of blasting, transport, thick broken, thin broken material (there are huge costs ), when the dry election is not magnetic, so it is wasting the waste. Is only the magnetic material fine weathered broken and a small part of the fines. Reason that led to this result, broken system does not provide sufficient crushing capacity of dry granular materials are not selected under control, in fact, throw away the wastes contain large quantities of iron.
If the broken system can provide-10mm material, then dried significant increase in efficiency will be selected to not cause such a massive waste.
Therefore, be sure to ore crushing to-10mm below, then Dry operation. To achieve such a crushing effect, it must be from the crushing process and to study the impact of broken equipment and configuration. The current rough jaw crusher(PE400 * 600, PE500 * 750,
