Which Air Compressor Should Be Select for the Cement Industry?

Compressed air is an essential utility in the cement industry. It powers tools and actuation cylinders and is used for filtration, cleaning and cooling.

In addition, it is required for plant and instrument air, pneumatic conveyors and aeration systems in the cement silos. It is easy to take these services for granted until they are not available.

Piston Compressors

Cement manufacturing is a demanding process that requires the proper compressed air operations with Industry Customized Energy-Saving Air Compressor for efficiency. Pneumatic conveying systems and pneumatically powered aeration systems are used extensively to move fine cement powder from storage to production and keep it flowing smoothly during the production process. These systems require large amounts of compressed air and can be expensive to maintain. The right air compressor design can help you optimize your operations and save money in the long run.

The piston, or reciprocating compressor, is one of the most common types of compressors for industrial use. It uses a crankshaft to move the piston back and forth in a cylinder, compressing the air with each stroke. The compressor has two operating modes: continuous and intermittent. Continuous mode is used for high volume applications while intermittent is used for lower volumes at varying pressures. The piston compressor is available in a variety of sizes to meet the specific needs of your business.

Piston technology is the oldest type of air compressor and the simplest, using very basic physics principles to function. This simple technology results in easy to understand components that are more easily obtainable and replaced by their manufacturers, providing for cost-effective maintenance.

A piston compressor has the advantage of being more quiet than most other types of compression technology. This is due to the fact that the pistons move much more slowly than other compression technology. Piston compressors are also highly durable and require very little maintenance, making them a great choice for applications with harsh environments.

Piston compressors are available in a variety of options, from the Contractor Series for home use and construction applications to the Professional and Industrial Series designed for medium-sized local businesses or factories. If you’re interested in learning more about the different series and what size piston compressor would be best for your business, talk to a knowledgeable member of our team.

Compressed air is a vital tool for a wide range of applications in the industrial world, from cleaning and conveying to aeration and combustion. CAM Technologies has the knowledge and experience to help you select the compressor and air treatment system that will make the most of your industrial compressed air.

Axial Compressors

Axial compressors utilize a combination of rotating and stationary components. A shaft drives a central drum, retained by bearings, which has a number of annular aerofoil rows attached (referred to as rotors). These are rotated between a similar number of fixed aerofoil rows (referred to as stators) mounted on a stationary tubular casing. The rotors impart energy to the air by increasing its rotational kinetic energy, while the stators convert that increased kinetic energy into static pressure via diffusion. The process of compressing the air into a smaller volume requires a large number of stages, with each stage raising the pressure by a significant percentage of Energy-Saving Air Compressor.

Stator blades are very similar to those found on a propeller, and each produces unsteady flow variations that seriously affect the overall compressor performance. The result is that axial compressors typically require complex wind tunnel testing and sophisticated computational models to determine their normal operating points, and the desirable operation map which extends beyond them.

For the cement industry, a compressor that can achieve high air-to-matter ratios is required to help keep fine, dry cement powder from clumping. The air needed to perform this task is delivered through pneumatic conveyors and aeration systems that consume large amounts of compressed air. This air must be available in sufficient quantities to meet the demand, even during the most intense periods of production.

This is where the axial compressor excels. It is a versatile, highly efficient machine that can operate at a wide range of corrected rotary speed values. The resulting operational flexibility is a major benefit in comparison to centrifugal compressors.

One of the largest current users of axial compressors is to supply air for catalytic cracking, which is an essential step in producing petroleum-derived fuels. The required pressures can vary from 50,000 to 300,000 cfm at discharge pressures of 25 to 50 pounds per square inch gauge (psig). The high capacity requirement means that a compressor with an efficiency that approaches 100 percent is usually the best option. An evaluation must be made to weigh this against the size and cost requirements, however.

Oil-Free Compressors

Compressed air is used for a variety of applications in the cement industry. This includes conveying, aeration and powering tools or actuation cylinders for the production process. This means that it is important that the compressed air is clean and dry to ensure that there is no contamination with oil. This is why an oil-free compressor is an ideal solution for the cement industry.

The oil-free compressor works in a similar way to an oil air compressor, but without the need for oil to lubricate the moving parts. This means that the machine produces less heat, and this in turn reduces energy consumption. Oil-free compressors are also quieter than oil lubricated models.

As well as reducing energy costs, an oil-free compressor will help to increase uptime and productivity. This is because the machine is less likely to be affected by mechanical wear and tear, which can often occur with a compressor that uses oil for lubrication. This is because the parts are constructed to prevent any contact or rely on another method for lubrication, such as water or Teflon coating.

When one of the base load compressors at Golden Bay Cement in Portland, Whangarei began to perform unreliably, Machinery Health Technician & Air Services Section Engineer Aaron Polwart knew that they needed to find a quick and efficient solution. With two Kaeser compressors already onsite working reliably, they decided to replace the failed compressor with a new DSDX 305 series rotary screw compressor.

The DSDX rotary screw compressors from Kaeser feature a number of technologies that optimise energy efficiency. This includes the flow-optimised Sigma Profile rotor design which reduces pressure drop across the compressor and the use of high performance IE4 drive motors, which comply with – and exceed – EECA regulations in New Zealand.

The new compressors are equipped with a Variable Speed Drive, which allows the speed of the compressor to be adjusted depending on demand. This is especially beneficial when the plant is working at full capacity, as it can cut energy consumption by up to 30%. This helps to further reduce energy costs and emissions.

Centrifugal Compressors

The centrifugal compressor is a high-pressure compressor and Magnetic Levitation Centrifuge that uses a series of stages to achieve the desired pressure ratio. Each stage takes up a part of the total pressure rise, and the overall result is a compression ratio that is higher than an axial compressor or a piston compressor. This makes it a popular choice for the cement industry, where high-pressure air is needed to power machinery and operate tools.

This type of compressor can be used to compress oil and gas, but it is also commonly used in air conditioning applications. It is an ideal option for applications that require 100 percent oil-free compressed air. The compressors are typically powered by ultra-high speed electric motors that do not need a gearbox or associated lubrication system. In addition, these compressors are generally compact and can be installed in a smaller footprint than other types of industrial compressors.

A simple centrifugal compressor has four components: an inlet, an impeller/rotor, a diffuser, and a collector. The working fluid passes through the impeller, which is a rotating wheel, increasing its kinetic energy as it moves inward. This kinetic energy is converted into potential energy, which is transmitted to the working fluid by the diffuser, which has a shape that looks like a snail shell, bull's horn, or French horn.

The collected working fluid is then discharged into a circular collector that can have different shapes and sizes, depending on the design of the compressor. It can be shaped to have a constant area or to have a varying volume, and it is designed to collect a specified volume of the working fluid at a rate that will match the requirements of the application.

Air compressors can be used to power a wide range of equipment in the cement industry, from pneumatic conveyors to ash handling systems. Compressed air is required to keep a number of processes running smoothly and quickly, including mixing and grinding. Without the help of air compressors, these essential parts of the production process would not be able to function. In addition to ensuring that the entire production process runs smoothly, air compressors also help to make sure that the resulting product is of good quality.
