In addition, there is much other raw material used in cement manufacturing. Addition of those materials is based on the requirements of the production. After the collection of the raw materials, proportioning and grinding is done. In general, limestone and clay contents are 80% and 20% respectively.

In our labs, we have been able to develop a new chemical for Cement Additives that not only enhances the grinding and performance efficiency of cements but also increases its compressive strength. It improves the compressive strength of cement tremendously. Increases the grinding efficiency by 7-15% thus increasing the output of grinding mills.

ORE GRINDING Grinding is an important industrial opera-tion that is used for the size reduction of materials, production of large surface area and/or liberation of valuable minerals from. their matrices. In addition to mineral proces-sing, it is widely used in the manufacture o:f cement, pigments and paints, ceramics, pharmaceuticals, and cereals.

Cement additives are materials added to cement for the optimization of the cement properties and the cement grinding process. Cement additives are classified into different product groups such as grinding aids, strength enhancers and performance enhancers. ... SCM) and varying conditions during the cement grinding process. In addition, local ...

In addition, fine (700 microns) grinding of high-fiber feed ingredients has been shown to improve their feeding value. As a rule of thumb, if there are whole kernels in your feed, it is probably not ground fine enough,a nd you may be losing 5 to 8 percent in feed efficiency.
