FAM designed crushers are used for crushing minerals, raw materials and other bulk commodities.. The types of crushing machines are distinguished by their working principles: by pressure, impact, hammer, or shear. In contrast to mills, crushers process the feed materials into grain sizes from coarse to medium granulation.

14 Cement Mill and Bag House . Clinker, along with additives, is ground in a cement mill. The output of a cement mill is the final product viz. Cement. In a cement mill, there is a cylindrical shell lying horizontal which contains metallic balls and as it rotates, the crushing action of the balls helps in grinding the clinker to a fine powder.

Quick Setting Cement Features. It has a high strength of 6000 PSI within 1.5 hours. It features less cement usage and fast hardening speed.

3. 3 • Cement is a fine, soft, powdery-type substance • It is made from a mixture of elements that are found in natural materials such as limestone, clay, sand and/or shale • When cement is mixed with water, it can bind sand and aggregates into a hard, solid mass called concrete Cement.

For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. Assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7, the width should be = 45.7 × 1.7 = 78 cm.
