Industry 4.0 digital innovations, from advanced data analytics to intelligent networks, offer tremendous opportunity to create value and raise the efficiency of production processes. Yet few cement producers have implemented 4.0 advances in any systematic way. Producers that move quickly to employ 4.0 technologies can therefore gain a powerful competitive advantage over their peers.
In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker minerals form.

Retrofitting of a cement Plant Preheater Tower. Inspection by plant personnel revealed cracking in the concrete frame of a 326-ft-tall, 7-level preheater tower. Onsite plant engineers deemed the cracking significant, especially since the structure supports critical manufacturing process equipment.
Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
This requires energy to release. In a pre-heater or pre-calciner kiln, this occurs in the upper stages of the tower. Drying/heating Decarbonation (800C) Kiln Chemistry Decarbonation Decarbonation or calcination as it is sometimes termed, is the primary energy intensive reaction of cement kilns.
The unique retrofit resulted in a structure that is stronger, more serviceable, and more durable than the original tower. The project represented an exceptional team effort, and its success is attributable to the leadership of the owner and client, the ingenuity of the engineering team, and the resourcefullness of the contractor.
Preheater & Calciner Overview Preheater & Calciner Overview KHD Humboldt Wedag was the first company to introduce mul-tiple products to the cement industry. Most of these are still the market standard today. This fact underlines our position as technology leader and expert in the field of cement production technology.

At the time of installation, the plant had the highest capacity for single kiln. The plant was set up in the collaboration with M/s Fuller USA and its Indian associate Fuller KCP. In 2006, the plant was modernised and the capacity was increased to 2.6 million TPA. This was steadily increased to 3 million TPA (9100 TPA) till 2016.
Cement making process ... General Diagram of Preheater Reactions. In the tower, Preheaters do 40 -80% calcination. Precalciners do 70 to 96% calcination. The difference is the no. of stages, type of calciner, and often the available length of kiln.

preheater tower and the shorter kiln design. Depending on the number of stages on the preheater and manufacturer, the shorter kilns would typically be designed with three support stations or piers and be driven by a single or dual drive arrangement and girth gear. The three station kiln would typically have a length to diameter ratio of 15:1.
