Problems May Appear in Crusher Process

It is understood that the heavy plate feeder frequency control system under normal operating conditions, according to the primary crusher, load status (current signal) with the broken machine automatically adjusts to the mining speed conditions allow the formation of the largest capacity in abnormal case that the primary crusher, the crusher belt conveyor current overload alarm signal, according to process requirements at the same time reducing the running speed of the mine in the case of downstream equipment downtime, heavy plate feeder immediately interlock stop the stagnation points the buffer silo in ultra-high material level, automatic stop to the mining machine running. Downstream equipment downtime by-interlock according to process requirements.
The crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. The common crushing machine are impact crusher, winnowing mill, roll crusher, compound crusher. Jaw crusher (jaw crusher), with a crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic these advantages.    

Primary crusher units PX90/150 gyrating crusher: 380v, 180K; crushers units PYB2200 ; crushing machine are 3 units PYD2200Cone broken, 6kV. 280kW Crusher interlock start and stop and fault protection software PLC controller logic to achieve its start and stop on by the operator in ipc the Human Interface painting of direct manipulation or instructions issued directly by the logic software, its status signal into PIC in the IPC on the man-machine interface screen display, the current signal from the transmitter into the PLC in the IPC display and storage, there exception will automatically alarm or interlock shutdown coarse crusher handling capacity by iron feeding capacity of the board to the system machine decided to coarse crusher such as overload. Automatically reduce the frequency inverter and automatically improve the feeding speed Sizzling feeder feeding speed, reduce the feeding amount; coarse crusher appears underrun, increased feeding capacity ensure coarse, broken system neither downtime but also to achieve the maximum processing capacity of crushing.
  

As the crushing machine with coarse crusher belonging to two conveyor chains , the crusher incoming gravel surge bin feed into the crushing machine crushing Crusher feed tape. Crusher crushing the ore mountain with a belt conveyor, belt conveyor ingredients car distribution is further broken into the crusher. These are all very important parts of the beneficiation process, so we should pay extra attention to them.
