In mining, apron feeders play a major role in ensuring smooth operations and increasing uptime. They are very diverse in their …
Monitoring and preventing coal–rock dynamic disasters are essential for ensuring sustainable and safe mining. Induced charge monitoring, as a geophysical method, enables sustainable monitoring of coal–rock deformation and failure. The induced charge signal contains crucial information regarding damage evolution, making it …
In-stream analysis (ISA) systems provide continuous on-line analysis of metals and density in slurry streams around the flotation process. This information allows plant operators or a process control system to fine-tune and optimize the process much quicker after normal disturbances caused by variations in feed-rates, pulp density, grinding, head-grade, and …
Basic criteria that should go into properly sizing an apron feeder should include feed rate (peak and normal), material characteristics (such as moisture, gradation and shape), maximum lump...
Coal processing description from its geology mineral property to how to extract coal, and how to increase coal heating, related processing plant flow chart and layout design.
This learning resource will give you an an overview of the different ways coal is mined: drift mining; open cast mining and deep mining.
In a gravimetric feeder, control and local panels load cells to measure the load, a digital tachometer senses the belt speed, and a belt feeder conveyor shaft operated by an AC motor connected through the gearbox completes the system. The gravimetric feeder may be a loss-in-weight system or a gain-in-weight system, depending on the overall process.
