Surface grinding machines for ceramics can be divided into (1) creep-feed grinding type and (2) reciprocating (speed-stroke) grinding type. Reciprocating grinding works with relatively small depth of cut and high speeds (up to 40,000 mm/min) and requires particular specifications of the driving system such as high damping and acceleration.

GRINDING MACHINES

reducing the gap between the wheels, grinding the work. Surface grinding produces flat, angular, or contoured surfaces by feeding work in a horizontal plane beneath a rotating grinding wheel. Work is most often magnetically attached to the table, and may be ground by either a traversing or rotating movement of the table.

GFRC Mix and Materials

Sand and cement are typically used at a ratio of about 1 to 1, although some mix designs call for slightly higher cementitious materials content (see "GRFC Mix Design," Concrete Décor, June/July 2008). With its high cement content and low water-cement ratio (0.33 to 0.38), GFRC can dry out quickly and not gain full strength.

Concrete Dust Removal | Hunker

Whenever you work on a project that requires cutting, grinding or chipping concrete, you will make concrete dust. The primary ingredient of concrete dust is crystalline silica. According to Amicus, "For many years, it has been known that breathing in fine dust containing crystalline silica can cause lung damage (silicosis)."

A History of Cement

In 1902, in his Edison Portland Cement Works in New Village, NJ, he introduced the first long kilns used in the industry-150 feet long in contrast to the customary 60 to 80 feet. Today, some kilns are more than 500 feet long. Parallel improvements in crushing and grinding equipment also influenced the rapid increase in production.
