Clinker is the intermediate product used in the manufacturing of cement. There are two primary processes used to manufacture clinker: the dry process and the wet process. Our plants use the dry process, which is more energy efficient. In the wet process, the raw materials are mixed with water to form slurry, which is fed into a kiln.
1. READY MEXED CONCRETE PROCESS RMC. Ready mixed concrete process (R.M.C.) is the fresh concrete mix, which is produced by weigh-batching ready mix concrete manufacturing plant. under complete quality control and delivered duly mixed to the site of placement by truck-mounted agitators or dumpers.
In this process, the hydrated cement reacts with CO 2 in the air, slowly reversing some of the processes that took place in the kiln when the cement was made (this is the carbonation process; it also causes reinforcement corrosion, see Section 25.3.2). It is estimated that this may reduce the carbon footprint of the cement industry by 3–5%.
In the dry process, the raw materials are crushed first and dry mixed. Contrarily, in the wet process, the crude ingredients are wet-ground i.e., water is added whilst their crushing. Both of these methods are discussed in detail. The figure below delineates the general process diagram for the manufacture of cement.

Stage of Cement Manufacture. There are six main stages of the cement manufacturing process. Stage 1: Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite. The ore rocks are quarried and crushed into smaller …

The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. The limestone is excavated from open cast mines after drilling and blasting and loaded onto dumpers ...

Cement Manufacturing Process. Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
b) Wet Process The raw materials are firstly crushed and made into powdered form and stored in silos. The clay is then washed in washing mills to remove adhering organic matters found in clay.
In the wet process and long dry process, all of the pyroprocessing activity occurs in the rotary kiln. Depending on the process type, kilns have length-to-diameter ratios in the range of 15:1 to 40:1. While some wet process kilns may be as long as 210 m (700 ft), many wet process kilns and all dry process kilns are shorter.
Fig. 2.3 Flow diagram of a Humboldt gas suspension preheater, a multistage counterflow process which draws the gases through a series of cyclone collectors. The pulverized material, which is fed counter to the gas flow, becomes suspended in the gas stream and is heated in successive stages until discharged through the kiln-feed pipe.

A concrete truck may be able to pull up to the site and pour right into the forms. If the site is on the other side of the house or building, the truck may pour into wheel barrows or a concrete pump to get the wet concrete to the site. Concrete should not be placed when temperatures will drop below 20F.
