According to the different methods of discharging material, cement ball mill can be divided into central discharging type and circum discharging type.The diameter of the hollow shaft neck of the discharging part is much larger than that of the over-flow ball mill with the same specifications which is to reduce the slurry level and to speed up the cement mill speed through the pulp.It grinds the rock and ore by way of the pressure of the cement and the grinding force.When the cement hits the ore, firstly it is broken into thick bead, and then grinded to smaller magnetic particles.Cement and concrete is the line between contact, and the ball and the goal contacts with dot, and therefore, when inner goes up along the rotation, during which clip thick bead is taken, which is like article cement screen effect makes fine grain go through from cement seam which also is helpful for breaking thick bead and make the coarse grain concentrate where grinding medium blows.For this reason, this grinding machine has excellent selective grinding effect and the granularity of the finished products is even and the over-grinded products are few.
Grinding aids can give benefits of 5-15 per cent in production but need to be continuously evaluated for cost effectiveness.Unfortunately, their cost has risen more rapidly than the cost of energy in recent years and the economic balance has to be re-evaluated.The benefit of aids on cement flowability has to be considered, along with the added scope for reduction of cement clinker content with some modern additives.Correct timing on the maintenance of a first chamber cement mill lining and the successful implementation of an expert system on a cement mill both offer benefits in terms of power consumption (see case studies panel).Accurate process measurements are also key to energy saving opportunities.Air compressors are another area for attention.Often, these are multiple units operating on a cycle of on- and off-load.Replacement of one (of three) with a variable-speed type (see table 2) can provide rapid payback.Even lighting and buildings offer excellent opportunities for power savings.Table 3 shows the 40-80 per cent energy savings that can be achieved by simply replacing old lighting systems.Buildings such as the new italcementi group research and innovation centre (i.Lab) in bergamo, italy, demonstrate that good building design creates significant savings.
