Cement Conveying System - Cement/Fly Ash Feeding System

Boost in infrastructure is must for global growth. Increased investment in infrastructure projects and its rapid implementation has the potential to drive the growth story of any economy. Accelerated infrastructure investments will not only de-bottleneck the system, it will also create its own demand. This can be best seen in the growth story of country like China where infrastructure has been built and developed at a spectacular pace and this has resulted in double digit growth for China and defied the boom bust theory of economic cycles.

Construction is one such area related extensively to infrastructure. It has become imperative to use innovative technology and efficient systems to increase the overall efficiency of the process. Cement conveying system (cement/fly ash feeding system) is one such example. These systems go hand in hand in the timely completion of construction linked projects which plays a pivotal role in infrastructure growth.

Cement conveying system (cement/fly ash feeding system) is used extensively at batching plant sites where it is used for conveying or feeding cement/fly ash into silos. The optimum productivity of batching plant depends on how fast the cement/fly ash received at site is transferred to batching silos.

Cement is fed into cement conveying system (cement/fly ash feeding system) either from bags or from bulker. If cement is brought in bags, it is fed into hopper provided in the system from where it is conveyed to the silos with the help of air flow from roots blower (rotary compressor). If cement is brought in bulker, it is directly connected to the system mechanism and conveyed to the silos with the help of air flow from roots blower (rotary compressor).

All About the Twin Lobe Roots Blowers

Roots blowers equipped with impellers consisting of two lobes are referred as twin lobe roots blowers.

Operation of Twin Lobe Roots Blowers

The roots blowers are primarily of the twin lobe configuration and have a pair of impellers with two lobes equipped in each. These are eight shaped impellers rotating in opposite directions on the parallel situated shafts. In these positive displacement or PD type roots blowers the lobes work against the varying pressure to move the air trapped in the spaces between impellers. The impellers in the blower or the air compressor rotate in opposite direction thus carrying the trapped air to the outlet of the compressor.

The impellers rotate at a constant speed at a constant pressure and constant temperature to displace the required volume of air for efficient performance. The volume of air discharged by the blower depends on the speed of the impellers rotating inside the blowers and pressure of the air. The modern air blowers are equipped with the timing gears. These timing gears will control the position of the impellers relative to one another thereby helping to maintain small and definite clearances in between. Therefore lubrication is not required within the air casing in the blower.

As the operation of twin lobe postive displacement roots blower is dependent on the rotation of the impellers these are also referred as the rotary positive displacement blowers at times.

How are Twin Lobe Roots Blowers different from the Tri-Lobe Blowers?

The roots blowers are classified into two categories – twin lobe roots blowers and tri lobe roots blowers. The basic difference between both of them is the number of lobes in the impellers of each. While in the twin lobe blowers there are only two lobes, the tri lobe roots blowers are equipped with impellers consisting of three lobes each. For high pressure and heavy duty applications tri lobe roots blowers are better options than the twin lobe configurations. The tri lobe roots blowers can compress and sweep nearly 6 times the volume of air/gas in a revolution as compared to twin lobe roots blowers.

Applications of Twin Lobe Roots Blowers

Pneumatic conveying system, sewage treatment plants, central vacuum cleaning system, aeration in storage silos, charging of kilns in cement and steel plants, effluent treatment plants and water treatment plants are some of the areas where these twin lobe roots blowers are widely used. These Twin Lobe Roots Blowers are used for numerous applications in cement, steel, aluminum, power, chemical, pharmaceutical, petro-chemical, food processing, dairy, space, textile and construction industries.

Conclusion:

The roots blowers are important equipments in several industries. Their operation is based on rotation of the impellers which are responsible for movement of air for various applications in industries.

Blowers for Water Treatment Plant

Positive Displacement Blowers for Water Treatment Plant

Blowers usually referred by different names like rotary lobe blowers, centrifugal blowers, positive displacement blowers and roots blowers are the air handling devices widely employed in applications where a relatively constant air flow rate is desired at varying discharge pressures. There are mainly two types of blowers used for industrial applications – positive displacement blowers and centrifugal blowers. While the centrifugal blowers are good for higher demands, the positive displacement blowers are employed in case where lower air flow per minute is desired at a higher discharge pressure.

Working of Rotary Lobe Positive Displacement Blowers

The rotary lobe positive displacement blowers are employed in various applications including water treatment, sewage treatment, pneumatic conveying in industries, cement plants, aeration tanks and for filter backwash in water treatment plants, aquaculture aeration etc. A blower typically consists of oval shaped casing in which two eight shaped rotors (having either two or three lobes) rotate to displace the air from the inlet side of the casing to the outlet port. The pair of rotors move in a circular motion at the same speed but in opposite direction. While one of them is driven by external power source, the other is driven by a pair of equal ratio gears. These lobes rotate and therefore displace the air from one end of casing to the other thus helping to achieve a constant flow rate at differential pressures.

Application of Blower in Water Treatment Plant

The impure water in water treatment plant is purified with the help of bacteria. The bacteria will purify the water by degrading the organic matter present in it. This bacteria requires oxygen during the process and therefore blowers in water treatment plant are employed in aeration tanks to provide sufficient air amount required by the bacteria to convert into oxygen required for the purification process. The rotary lobe positive displacement blowers are available today in energy saving features and therefore can be quite economical resources for supplying air required for adding up to the oxygen content in aeration tanks in the plants. As the rotors within the blowers rotate they draw air into the blower thereby filling up the space between them. The intake then closes and therefore the air will be trapped into the casing. The rotors keep on rotating until the air exits the outlet port. You can have a look at the twin lobe roots blowers for water treatment plants offered by Acme Air Equipments Company Pvt. Ltd..

Conclusion:

Therefore the air required for oxygen in water treatment is supplied with the blowers in water treatment plants. Multistage air blowers are desired in water treatment plants because these allow variation of the flow thereby optimizing performance and minimizing power consumption required at all operating conditions in the plant.

This article educates reader about positive displacement blowers and their application in water treatment plants.

Understanding the Usage of Air Equipments in Different Industrial Processes

Air equipments are machines that can mechanically compress air to be used in doing an industrial process. Some air equipments have filters used to remove impurities from the air especially those used in the medical industry. They are composed of nozzles which control the degree of air that is let out. In this article, we are going to focus on the uses of air equipments in industrial processes and their benefits.

Why do we need Air Equipments in different Industrial Processes?

Air equipments are important in industrial processes as they convert power from an external source e.g. electric motor or diesel into stored energy. The stored energy is then released as pressurized air which can be used to power industrial tools and machinery. This greatly reduces the power costs that industries have to incur to run their businesses. The pressurized air energy is also environmental friendly. This ensures that industrial processes have a positive impact on the environment. Industries use compressors to produce stored air and industrial gas. This stored air can be breathable e.g. gas used by scuba divers and in hospitals. Other stored gas can be used in the welding industry and also by firemen.
