  1. In general, Portland cement is the main production of cement industry. Portland cement is kind of meticulous powder, usually gray, which consists of calcium (from limestone), silicate, aluminate (clay) and ferrite. Limestone is the main raw material of cement production; most factories are located in the vicinity of limestone quarries in order to minimize transportation costs. Cement Crushing Equipment Usually we extract raw materials (limestone, shale, silica and pyrite) by blasting or by using cut-off equipment. Raw materials are sent to the crusher to be crushed or hammered into fragments. Usually primary crusher is Jaw Crusher while Cone Crusher and Impact Crusher works as secondary crusher. Cement Mill In the Raw Mill plant, we use vertical grinding mill and Ball Mill for cement further grinding. At this stage, vertical mill works by using the pressure of cylinder leakage to break the materials; ball mill is dependent on the steel ball grinding upon materials. Grinding Equipment works with higher capacity and saves energy greatly by using an electrical automation system which optimizes the grinding process. Apart in the raw mill plant, ball mill is also widely applied in the clinker grinding process. Here the cement clinker is grinded into fine powder together with other raw materials, such as gypsum. Primary crusher: For cement primary crushing, we recommend Jaw Crusher to you. With simple structure and high quality, Jaw Crusher works with higher capacity and lower cost. Secondary crusher: For cement secondary crushing, you can choose CS Series Cone Crusher or Impact Crusher. Although their working principle is different, both the crushers are widely applied as secondary crushing equipment. You can choose right one according to your requirement.

  2. <P>1. The little pineapple snaggletooth<BR>In the daily use of <a href="http://www.ksmachines.com" >Ball Mill</a>, the little pineapple snaggletooth happens most often, the reasons are as follows:<BR>(1). The little pineapple design strength is weak, and the manufacturing quality requirements is relatively low.<BR>(2). The lubricating of the little pineapple is bad, the mesh is bad which lead to localized wear, bubbling, and material quality coming off. The local stress concentration is worsened which speed up the snaggletooth.<BR>(3). Supercharge caused by the too many steel balls added into the <a href="http://www.flotation-machines.com/ballmills/Coal-Ball-Mill.htm" >Coal Ball Mill</a> in production primary which lead to the coal ball mill electric current reaches to 130A. Decrease the steel ball loading capacity, keeping the current at around 120A. (the current raises 1A with one ton steel ball added,)<BR>2. The little pineapple tooth surface abrasion<BR>The gear wheel surface generally presents bubbling, peeling, scallops, and such corrosive pitting phenomenon. Besides the little pineapple tooth surface temperature is high which makes the coal grinding ball mill gear teeth attrition condition seriously.<BR>The reasons are as follows:<BR>(1). The coal grinding ball mill protection cover sealing is not good. There is no sealing on the association point of activity and inertia between the <a href="http://www.ksmachines.com/Coal-Mill.htm" >Coal Mill</a> hollow shaft and shelter which speed up the ash entering to the big pineapple. The preheater of the boiler is the three branch warehouse, with one way the secondary air of the blower, one way the primary air of the primary air fan. As the primary air pressure is over-high, it blows down the ash accumulated from the smoke side carrying by the preheater heating surface and takes it away. The pipeline weld bond of the hot air system is unqualified which leads to serious leakage. The ash then enters to the wheel gear shield and speed up its attrition.<BR>(2) The alignment pin problem: It is regulated that the temperature difference measured along the little cutter teeth width should be no more than 8??, and the highest temperature on the tooth surface should be no more than 100??. Hit the alignment pin in after the intervals between each part is normal. When the temperature difference is more than 8??, raise the bearing end of low temperature. One of the reasons for the ball mill tooth surface attrition is that the alignment pin is not hit due to the great work amount which is also the reason why some individual little cutter teeth surface is high and the two ends temperature difference is relatively large.<BR>It consists of motor, reducer, case, milling device, separator, outlet, coal feeding pipe, loading device, control box and sealing apparatus. The fittings are all of superior performance in the world at present. We ensure good quality and durability of the whole machine.<BR><BR>1) The concrete base weight required is only 3 times of that of other similar machines thus the construction expenses is greatly reduced <BR>2) Small vibration while using and doesn't need shock-absorbing device<BR>3) Large load adjustment scope, so it can run under various environments<BR>4) Can bear very strong explosion pressure<BR>5) The grinding roller adopts new material and new craft, which ensures long service life and low maintenance cost<BR>6) There is gap between the grinding parts; it can start with load or offload.
