Cooling fans are used to blow cool air and bring down the temperature of the clinkers during the clinker process in the cement manufacturing. Once the clinkers are cooled, they are crushed to a fine powder which is considered as the cement. Exhaust fans /Dedusting fans are used to dedust the plant and also exhaust the unnecessary gases.

The basic process in a cement production plant is burning a mixture of raw material containing Carbonates and Silicates in a kiln to produce solid oxides, clinker, which is then cooled and milled to make the cement dust. Fig. 1 shows the structure of a rotary kiln with the most important variables used for control purposes in a simplified way [3].

The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

Generally, the proportion of components in cement raw materials is 67-75% limestone, 10-15% clay, 0.5-1.5% iron ore and 8.5-11% coal. The laboratory of a cement plant. With the help of vertical roller mills or other types of crushers, the raw materials are blended and further ground into smaller pieces of raw meal in the cement plant.

N. NeelRao. Cement industry relies heavily on industrial fans for key processes like raw material handling and exhaust gas removal. There are many types of process fans used in cement plants including raw mill fans, induced draft fans, cooling fans, raw mill exhaust fans, coal mill fans, and cooler exhaust fans. Each of these fans …

The grate cooler is a quenching type cement cooler applied for the cement manufacturing plant. According to the movement mode of the grate, the grate cooler can be divided into three types, rotary type, vibrating type, and push-type grate cooler, with the development of cooler technology, push-type grate cooler is considered the most common clinker …

Before starting to build a cement plant, it is imperative to know what the cement making process involves. The cement manufacturing process starts with mining of limestone followed by grinding it with other raw materials like clay, shale, bauxite, iron ore, etc. to prepare a raw meal, which is heated at a sintering temperature of 1,400 to …

The ID fan exhausts the clean gas from the bag filter. The process filter data and the technical specifications are given in Table 1. As the plant capacity was increased, the differential pressure across the bag house became a serious issue and led to the frequent failure of the filter bags, as well as reduced bag life.

As Clinkerization process is an endothermic (heat absorbing) process it requires burning of Suitable fuel. Remember almost 40 % of the total cost spent for manufacturing cement is for fuel and power. The specific heat consumption of modern plant ranges 690 to 800 Kcal/kg clinkers.

Being world 2nd largest cement producer, Indian cement industries have large requirements of Fans. Witt India supports the cement industries by supplying many types of fans with lowest power consumption than fans by any other competitor. These include the process critical fans, mainly centrifugal, for the pre-heater exhaust, kiln induced ...

At the core of this process sits the preheater and the rotary kiln, processing ground limestone and clay at temperatures of more than 1,300°C. That's a lot of heat… yet in many cement plants, much of it still disappears via flue gases and surface dissipation – as much as 40%-45% of what's put in.

In dry process technology, crushed limestone and raw materials are ground and mixed without addition of water. Dry and semi-wet processes are more energy-efficient. The wet process requires 0.28 tons of coal and 110 kWh to produce one ton of cement, while the dry process requires only 0.18 tons of coal and 100 kWh of energy [4].
