A concrete pump may be used in the construction of silo walls by slip form. As the concrete pump has accelerated the rate of concreting, so much faster progress we can expect. Through this process of concreting, we can reduce manpower engagement. Concreting by a concrete pump in slip form work gives us a better quality of concrete by reducing the handling of concrete in different stages. As the pouring time in the case of using a concrete pump is less so we can pour s complete & uniform layer well before the initial setting time of concrete. And this practice gives us a smooth surface of the wall. Concrete pouring in uniform layers well before the initial setting time of concrete has helped in the uniform lifting of the slip form so we can able get a better reading with the plumbs. By the above discussion, it is clear that concreting by slip form work gives us a lot more control over the quality of concrete, accurate plumb of the structure, and better surface of a concrete wall. Not only that it's a much more economical process to get the exact technical specification required in the actual operation of the structures, as the engagement of labour is less & the progress of work is faster.

Silos are more commonly used for bulk storage of grain, coal, cement, carbon black, woodchips, food products, and sawdust. Three types of silos are tower silos, bunker silos, and bag silos. There are different types of cement silo / Fly Silo such as the low-level mobile silo and the static upright cement silo, which are used to hold and discharge cement and other powder materials such as PFA. The Cement low-level silos are fully mobile with capacities from 10 to 75 tons. They are simple to transport and are easy to set up on-site. These mobile silos generally come equipped with an electronic weighing system with a digital display and printer. This allows any quantity of cement or powder discharged from the silo to be controlled and also provides an accurate indication of what remains inside the silo. The static upright silos have capacities from 20 to 80 tons. These are considered low-maintenance options for the storage of cement or other powders. Cement silos can be used in conjunction with bin-fed batching plants
We have cutting-edge technology that allows us in offering Construction Services for Cement Silos / Fly Silos. These storage silos are fabricated using high grade material of construction and are stringently checked on well-defined parameters. Widely used for high-grade coatings, these are provided in two different configurations such as skirted silo or spread-leg silo as per the requirement.
In RCC Cement Silos / Fly Silos construction, the formwork involves considerable material and labor costs and involves time. Thus, the overall cost depends significantly on the formwork. It is very pronounced in the case of structures of large heights. Engineers and contractors always strive to rationalize the formwork to the extent possible. For many cases, slip form is considered the right solution for these tasks.
We are an organization engaged in offering various types of Cooling Tower Construction services. We have in-depth domain knowledge, facilities, and workforce to undertake these construction services effectively. Premium-grade material is used in the construction process while adhering to industry standards. The construction services are cost-effective and timely completed to meet the growing demands of clients. The construction services are cost-effective and timely completed to meet the growing demands of clients. Construction Services for Cooling Towers are heat removal devices used to transfer process waste heat to the atmosphere. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed-circuit dry cooling towers, rely solely on air to cool the working fluid to near the dry-bulb air temperature.
This is the photograph of Blending Silo after the completion of the slip formwork. Blending has a 15m diameter & 52m tall structure. Here concrete pump had used for concreting the wall. We can see here the surface & alignment of the wall is almost accurate. The average rate of lifting achieved in this construction is 2.5m per day. So, the experiment of concreting by the concrete pump in slip formwork is successful. This experience has shown us a new way of working in slip form to achieve a better quality of construction. It was constructed in phases. 1st up to +15m (wall thickness 800mm) has taken 8 days and 2nd from +15m to +52m has taken only 22 days.
Through the successful experiment of Blending Silo slip formwork, we constructed the clinker silo by the same process of concreting and made it a second time successful. Clinker Silo is the biggest silo in our Lafarge Sonadih Project. It has 45m diameter & 26m tall. We have used here 3 nos. of concrete pump for feed the concrete during slip form works. The total wall length had divided into 3 parts and to feed each area a concrete pump has engaged. We have also been successful here by adopting this process of concreting in slip form. The duration taken in the construction of the clinker silo was only 19 days.
In the clinker silo, we have used three nos. of a concrete pump to feed the concrete into the wall during slip formwork. Photographs are showing the concrete pump used during slip-form work. The concrete pump shown in the photograph feeds a one-third portion of the silo wall.
A boom placer is also being used to feed the concrete to feed another one-third portion of the silo wall. This photograph has been taken during slip for work of clinker silo. By the above process, concrete feeding has been done for concreting work at the clinker silo.
This photograph has taken during concreting done at Clinker Silo. Here we can see the concrete has poured to slip from the shutter through the hose pipe of the concrete pump pipeline and this hose pipe has connected to the main pipeline of the concrete pump.
After the successful completion of the Blending & Reject Silo in this process of concreting, we have applied the same process of construction of another one no. of the silo (Reject Silo). Reject Silo has 12.5m diameter & 35m tall. We have completed this silo wall by slip form only by 13 days with maintaining a better quality of work & safety.
There is a chance to disturb the plumb of slip form during concreting concrete pump due to vibration produced by a concrete pump during each stroke. To avoid this vibration, we have to use a spring pad. During concreting work, the spring pad is to be placed under the concrete pump line near the slip platform where the pipeline gets bend. This can minimize the vibration produced by concrete pumps.
An industrial chimney is an arrangement for the ventilation of hot flue gases or smoke from a boiler, stove, furnace, or fireplace to the outside atmosphere. An industrial chimney / flue-gas stack is a type of chimney, a vertical pipe, channel, or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood, or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler, or another large combustion device… These types of industrial chimneys may be used in Power plants, Chemical plants, Cement plants, Hydro, and gas plants The height of industrial chimneys plays a role in their ability to transfer flue gases using the stack effect, the dispersion of pollutants at higher altitudes helps to ease down its influence on surroundings. In the case of chemically aggressive output, the tall industrial chimney allows partial or complete self-neutralization of chemicals in the air before they reach the ground. The dispersion of pollutants over a greater area reduces their concentrations in compliance with regulatory limits.
we are specialization in manufacturing industrial chimneys for diverse industrial segments. We undertake designing, erection, manufacturing as well as executing work of industrial chimneys for providing all the solutions to the clients under one roof.
Industrial chimneys are commonly referred to as flue gas stacks and are generally external structures, as opposed to those built into the wall of a building. They are generally located adjacent to a steam-generating boiler or industrial furnace and the gases are carried to them with ductwork. The use of reinforced concrete has almost entirely replaced brick as a structural component in the construction of industrial chimneys.
