Crushed Limestone Uses & Benefits of This Natural Stone

Moreover,. Crushed limestone aggregates proved nearly 10% of high in strength compared to traditional gravels used in cement-concrete mixer. The strength comes from the angular shapes and sharp edges of crushed limestone aggregates compared to rounded-shaped gravels obtained from natural resources, which formed through weathering processes.

Portland Cement Lehigh Hanson, Inc.

Cement-making requires calcium, silica and small amounts of alumina and iron. Raw materials rich in these elements include limestone, sand and clay. They are quarried at the cement manufacturing plant or shipped from nearby. Limestone, the source of calcium, makes up about 80% of the raw materials for cement.

Jaw Crusher Working Principle

The ore enters from the top and the swing jaw squeezes it against the stationary jaw until it breaks. The broken ore then falls through the crusher to be taken away by a conveyor that is under the crusher. Although the jaws do the work, the real heart of this crusher is the TOGGLE PLATES, the PITMAN, and the PLY WHEEL. Forced Feed Jaw Crushers
