Ball mill in the application of the reuse of fly ash

<p>Ball grinding can be after the original grey or separation of crude ash mixture of ultrafine grinding, make it has a certain hydraulic activity, can produce a mixture of high performance concrete advanced blending superfine ash, achieve the goal of full use of fly ash, create greater economic benefits.</p><p>In addition, in the concrete mixed with fly ash saves a large amount of cement and fine aggregate; Reduce the water consumption; To improve the workability of concrete mixing; Enhance the pumpability of concrete; Reduced the creep of concrete; Reduce the hydration heat, heat expansion; Improve the ability of concrete permeability; Increase the concrete modification. This would require the ball mill to grinding depth, fly ash for reuse. Ball grinding mill is used to analyse the fly ash powder grinding mill, this kind of technology in the cement industry has been used for many years, has been quite mature, ball mill products are relatively series.</p>

<p>Various high fine at home and abroad for reference, the high yield and the principle and structure of cement grinding mill, our country has successfully developed the fly ash for fine grinding ball mill, the original grey or coal-fired power plants emit to carry on the fine grinding, coarse ash to ash fineness of finished product.</p>

<p>Add a sorting device, after the ball mill will have a sorting after ball mill grinding of coal ash and return after sorting will be thick ash ball mill ultrafine grinding, can produce a senior preparation of high-performance concrete admixtures (powder), improve the comprehensive utilization of fly ash. Ball mill in the application of aerated concrete equipment: fly ash by electromagnetic vibrating feeder, belt conveyor into ball mill, grinding fly ash after fine fly ash pump were sent to the slurry storage tank. Lime by electromagnetic vibrating feeder, belt conveyor into the jaw crusher for crushing, after crushing limestone by bucket elevator into lime storage, then through screw conveyor into the ball mill, after fine grinding of the material by screw conveyor, bucket elevator and into the powder mixing tank.</p>
