Aactive limestone production line process
Active limestone production line consists of vertical preheater, rotary kiln, three main host of vertical cooler and exhaust gas treatment system,consisting of pulverized coal preparation system.
Broken qualified limestone is stored in bins, and is brought into preheater upper hopper through the conveying system. The feeding amount of Preheater top hopper is controled by 2 up and down level gauges , and then limestone evenly distributed to the Interior of preheater through a feeding tube.
Limestone in the preheater kiln is heated high temperature smoke, and then is pushed into the rotary kiln by the hydraulic push rod, limestone in a rotary kiln calcined through high temperature, burnt active limestone enter vertical cooler, and is discharged after being cooled by cold air in the cooler. The preheated secondary air enters the kiln, the exhaust gas in kiln outlet is discharged through gas treatment system.

Main equipments of Active limestone production line


Desulfurization Limestone Powder Preparation Method

There are basically three kinds of methods for existing desulfurization limestone powder’s preparation: dry tube mill, wet ball mill and dry vertical mill which have their own advantages and disadvantages. The mill set of crushing, drying, grinding, classifying, conveying as one, so compound crusher, Raymond mill, mobile crusher, and vertical milling machine become main Limestone flour equipment.

Due to preparative raw materials is a limestone ore, the same is grinding mechanism and cement raw material’s preparation, and the only difference is that the fineness of finished product, so most of the cement raw material’s preparative experience is applied to the limestone powders.
