B B1 INTRODUCTION Laboratory testing of cements and cementing materials is an essential part of the entire cementing process. Testing begins at the manufacturing sites of the cement and additives to monitor product quality, and it continues through the slurry design stages at the pumping service company or operating company laboratories as a specific formulation is developed.

The shape of the sand grains from our planet's deserts is too round to be used in concrete (1, 2, 3). This is why we are drawing the last sand resources from natural beaches for making concrete for the everincreasing human demands. Would it not make sense to crush the round desert sand grains in a mill to produce the sand required for concrete?

Abstract. Cement production is an energyintensive process. The cost of energy constitutes more than 60% of the cost of the cement; hence cement plants have to consider minimizing the cost of energy when planning production. However, there are several challenging issues regarding the production plan.

Assembling the Crush Grind Mill. Mount the crush grind mechanism into the mill body and mark the shaft where it sticks out 11/8" from the body. Cut the shaft at this mark and file the end to a taper. This removes any sharp burrs and makes the head easier to install. Now we'll use epoxy to glue the mechanism in place.
