Magnetite sand: Some beach and river sands contain high concentrations of magnetite. Magnetite-rich "black sands" are commonly encountered by people panning for gold. Although magnetite sands and other heavy mineral accumulations are common, they are infrequently developed as mineral deposits because their size or grade is inadequate. The pile in the photo is approximately four inches (10 centimeters) across.
The PC-based electrical control system monitors every function of the crushing plant and will shut it down if any problem occurs. The system includes Allen Bradley full-voltage and redundant motor starters: 4,161-volt for motors 200 hp (149 kW) and over; 480-volt for all others. The plant has the same kind of sophisticated filtering and sensing system as an aircraft, according to the manufacturer. And outside programmers can access the system from a remote location for troubleshooting if necessary.
Want even more control? We offer a complete automation program with touchscreen to adjust the gap settings either for hammer wear or ever-changing product demands. This full automation feature also includes hands-free calibration capability. Just give the command and let the crusher adjust accordingly.
Although the upfront cost of purchasing mobile crushing plant is relatively high, the economic and social benefit are great after putting into production. When users choose mobile crushing plant, they can have reasonable configuration on the basis of their actual requirement, or they could choose a good manufacturer who is fully responsible for the configuration. You get what you pay off, so do not stick to the price, and choosing a good equipment is foundation.
Cone crushers are used to grind down rocks, which are fed into the top of the crusher and pressed between the mantle and the cone. This breaks the rock down into smaller fragments, which are then passed through lower levels of the crusher where they are broken down further.

Nordberg® MP Series™ cone crushers feature a push button disassembly for routine maintenance. If needed, modular components can be easily replaced.
NW4MXS™ Rapid portable cone crusher has a four-deck inclined screen on the same chassis, providing high capacity for various applications such as aggregates production and recycling.
The liner profiles are designed for a range of product sizes, from extra coarse to extra fine. The extra fine liner profile will result in the highest fines proportion for a given cone crusher.
The particular crushing chamber adopting principle of intergranular lamination and matching rotor speed obviously improves the crushing ratio and productivity, largely increase the amount of cubic final product. Adopting hydraulic protection and hydraulic cavity clearing, high degree of automation, the hydraulic system can be up top and discharge automatically when the crusher is blocked instantly or over-iron, which eliminates trouble of halting to clear the material manually. It makes the maintenance more easier, cost lower. The hydraulic adjustment and oil lubrication make the crusher more steady and reliable. It also adopts labyrinth sealing mode, which avoids oil mixing with water easily.
Water conservancy and chemical industry: In dam construction, jaw crusher takes an important part in crushing process.
