SmallParticleSize Cement SPE Production amp Operations
The particle size of Class G oilwell cement is responsible for its limiteduse in specific remedial cementing operations. Because the largest particles ina typical Class G cement are in the 100- to 150- range, cement slurries willnot penetrate fractures narrower than about 0.4 mm or sandpacks finer thanabout 1020 mesh.
OK mill The most reliable and efficient mill for raw
Improved control over particle size distribution Product quality is a function of cement particle size distribution PSD and the dehydration of the gypsum within the cement. In the OK mill, parameters such as mill air flow, separator speed and grinding pressure
Cement Roller Press Roller Press In Cement Plant
Pre-grinding system after the material is pulverized by the roller press, all or part of them with a good extrusion effect will enter the subsequent ball mill for further grinding. This system has the advantages of simple processes, less equipment, wide particle size distribution, and stable cement performance.
Our modern vertical roller mill takes you further
With the OK Mill, easy switching between different cement types is possible, along with adjustment of particle size distribution PSD to match or to improve products made in existing mills. On November 11 2020, we held a webinar on the latest developments in operating and maintenance practices as well as new vertical roller mills innovations.
