<h1>New Cement Crafts with Roller Press Device </h1><strong> Author: <a href='http://www.articleseen.com/profile_momorubby.aspx'>momorubby</a></strong><br /><p>Cement is a kind of solidified hydraulic cementitious material. If cement mix with water through series of physical and chemical function, it would turn into tough rock from plasticity of the slurry. When it comes to solidifying condition, the cement can get solidified both in air and water. It can sustain and further develop the hardness. Therefore, cement material can be used in ground and underground projects. The universal cement for road and bridge contains 6 giant types of portland cement, ordinary portland cement, slag cement, pozzolanic Portland cement, fly ash cement, Portland cement and composite cement. Besides, alumina cement, expansive cement and rapid hardening cement can be used in some special projects. In the project construction, portland cement and ordinary portland cement are mainly applied. The wide utility of cement increases the producing demand of cement. The cement craft is also set with high standard. In the cement milling crafts, the roller press has been widely used in the modern cement firms. The craft procedure mainly applies slipping sieve material removal and breaking system. The main steps contains: put clinker, slag and gypsum into the material slip screening. The screening would select the material in the size less than 6mm into vertical roller mill under the vibration of eccentric motor. The bigger material would completely enter into roller crusher. In order to prevent any problem of roller press to influence normal creation of vertical cement roller mill during live operation, special bypass pipe and slip material screen switch are applied with electric limit control. If the crusher meets any problem, the slip material screen would be immediately turned on to let the material enter into the bypass tunnel. Meanwhile, the roller press would be checked to ensure normal running of cement vertical roller mill. The attention tips during the producing process of roller press: when the roller press is working, the rod valves should be opened to get max material entry. The working surface of roller should get even force on working surface. When the material enters from the bypass tunnel, the rod-shaped valves should be completely shut down. Especially, we should avoid any material entry into the crusher roller during abnormal working condition. After all material gets crushed, the machine can be shut down. Otherwise, the crusher would not get normally started. To some extent, the application of roller press will ensure the operation of vertical roller mill, improve the cement manufacturing crafts and lift up the cement production amount. It would greatly satisfy the demands of different clients. Qualified roller press in V-type classifier series will meet vast demand in future market. </p><strong>About the Author:</strong><br />I have written roller press and vertical roller mill many years, I know many thing of these marketing.
