| What is a Cement Silo? |

Cement silos are on-site storage containers used for the storage and distribution of various types of cement mixtures. Silos of this type come in a variety of sizes, making them ideal for use at many kinds of construction sites. A cement silo can be a permanent structure, or a portable model that can be relocated when necessary. Like many other types of silos, the cement silo usually is equipped with some type of blower to help expel the stored contents into a truck or other receptacle.
Cement powder is commonly made of lime and clay and is a key ingredient of concrete.
A cement storage silo can be structured to hold no more than a few tons of dry cement product, or be designed to efficiently hold several hundred tons. Generally, larger silos are permanent structures that cannot be moved. These are likely to be found at concrete plants, where the finished product is stored until it is time for shipment. Many building sites that utilize concrete in the construction process opt for portable cement silos that can be moved around the site as the need arises.
It is not unusual for construction companies to keep several portable cement silos available for different building projects. These simple storage devices can usually be set up in a matter of hours, then dismantled once the project is complete. Storage of the portable cement silo is relatively easy, since the components can be stored in a warehouse until the device is needed at another building site.

Cement mill is the core equipment for grinding material after clinker production. Generally, the cement mill can be called cement grinding mill. Among production cost of cement manufacturing, grinding powder consumption takes 35%-40%. The cement grinding plant is a vital link to control cement quality. To some extent, grinding quality can make up the shortage of clinker quality. In another word, the cement grinding mill can increase the cement quality and guarantee the qualification rate of cement. In general, cement mill can both apply for dry cement production and wet cement production.

| Waste heat recovery in cement plant |

It is an established practice to use alternate sources of energy to reduce cost of manufacturing. One of the proved practices is to have waste heat recovery system installed. Here is a case study with more details.
Energy is a major input in cement manufacturing process and is being met through captive power generation to run the operations cost effectively. On an average, energy cost is around 40 per cent of the production cost for cement manufacturing. Cement plants in India have installed coal based captive power plants (CPP), which are in operation for several decades. Before this technology was introduced, 30 to 40 per cent of the heat generated in the cement rotary kiln and after quenching cooler (AQC) processes of a cement plant were wasted and therefore, efforts were made to use the waste heat productively to bring down the cost of production. As a part of this process, since 2002, cement facilities started adopting waste heat recovery systems for power generation.
Waste heat recovery (WHR) power plant installed in cement plants, use the heat generated through rotary kiln preheater (PH) and AQC exhaust hot gases for power generation. These hot gases are used to generate steam in steam generator (Boiler) which is further used to generate electricity/power through steam turbo generator (STG). Typically 20 to 30 per cent power requirement of the cement plant can be fulfilled using this waste heat for power generation application, which is a substantial savings/reduction in the overall cost of production.
The number of preheater stages in a cement plant has a significant bearing on waste heat recovery potential. A preheater tower is likely to have four to six stages. Aged plants have 4 and 5 stage heat recovery in the preheater and thus have a higher potential for power generation. If the numbers of preheater stages are more, efficiency of the cement plant increases but has less potential for WHR power generation. Mid- tapping of AQC is important since it offers higher thermal energy or higher gas temperature. The potential of power generation is 25 KWh/tonne to 45 KWh/ tonne of clinker production.
There are three processes by which WHR0-based power plants are installed in a cement industry globally.
Steam Rankine Cycle System (SRC)
Organic Rankine Cycle System (ORC)
Kalina-based system
In India, SRC is widely used for WHR based power generation in cement plants. In SRC, exhaust gases from rotary kiln pass through preheaters (PH) and reach the preheater boiler. Similarly mid tapping from AQC induces hot gases to AQC boiler. One cement kiln line requires 2PH boiler and 1 AQC boiler. These boilers, based on heat source, generate Medium Pressure (MP) steam of 12 Ata to 18 Ata at temperature of 340 to 450 degree Celsius and low pressure (LP) steam of 2 Ata to 3 Ata pressure and temperature of 175 to 195 degree Celsius. For such application, Injection condensing turbines are used. Injection condensing turbines use medium pressure (MP) steam as inlet to turbine and LP steam is injected at LP side of the turbine. After this, combined steam is expanded at LP/Exhaust side to 0.1 Ata or 0.2 Ata based on water cooled condenser and air cooled condenser options.
Steam generation from hot gases is an important engineering and design aspect. Leading Indian boiler companies have developed expertise in steam generation, across various variable situations. Similarly Injection condensing turbines developed by Triveni for different MP and LP steam combinations are successfully working across Indian Cement Industry. These indigenised steam turbines and boilers helps in eliminating the dependency on Chinese boilers and Chinese turbines which were earlier being used in many WHR plants. While more than 60 per cent of cement plants have adopted WHR-based power plants, larger cement companies are considering WHR power plants for their Greenfield projects.
Triveni Turbines has supplied and installed several injection condensing turbines for cement WHR plants across India. Detailed design consideration is vital in injection and admission zone. Triveni Turbines rotors are designed with higher stability to offset the excitation caused due to fluctuating injection steam loads. Turbine mid-section and LP section is subjected to cyclic fatigue loads induced by thermal cycle and flow variations. Design and engineering teams carry out CFD analysis and creep fatigue analysis to address these issues. This design philosophy has made the turbines made by Triveni, robust and efficient for cement WHR applications.
Following are exclusive offerings of Triveni which makes it one of the preferred supplier for Cement WHR applications.
Integral Lube Oil tank: Triveni offer integral lube oil tank, for PHL and civil cost optimisation of TG house.
MRT: Triveni use live steam MRT for its turbines. Turbine is tested with live steam from boilers at Bengaluru works with job mounted turbo supervisory systems and woodward governor and gear box.
In-house manufacturing: Turbine components like blades, rotor, and casing are machined and manufactured and assembled in same work shop at Bengaluru.
Vaccum tunnel: High Speed Balancing of Turbine Rotor is done in “Schenk” Vaccum Tunnel at both Peenya and Sompura Works at Bengaluru.

A manual brick making machine is one that is operated with the help of laborers. This simply means that more human hands are required to operate these machines than automatic machines. These machines only rely on the skill of the operator. The manual brick making machines produce bricks in a variety of shapes, sizes, and types. It is available in three different specifications: 40 Ton with 10 HP power, 70 Ton with 10 HP power, and 100 Ton with 12.5 HP power.

The manual brick making machine process is relatively simple. This manual brick machine has hydraulic jacks for compression and a hydraulically operated power pack.
The workers mixed raw materials with a pan mixer. After preparing the raw material, it is loaded into the mold by the worker. Then the material is transformed into a brick shape by the machine pressing it with vibration. In this process, oil cooling system is used to keep the oil cool used in the machine. Following that, laborers will move the raw bricks to direct sunlight to dry.
