WhatsApp: +86 18838072829The first step in the cement process is the recovery of the limestone and sometimes the extraction of clay. Online elemental analyzers can monitor material chemistry in real time, allowing for adjustments that will help extend the life of the quarry. Belt scales and tramp metal detectors help monitor the process.
WhatsApp: +86 18838072829As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. The drum is generally divided into two or three chambers, with different size grinding media. As the clinker particles are ground down, smaller media are more efficient at reducing the particle size still further.
