The Pneumatic Group’s Role in Milling Operations

Rapid technological advances result in changes concerning the kinds of milling equipment preferred in the industry as well. Two types of systems, mechanical and pneumatic, are used to transport grains- raw material and end-product- to different locations within milling plants.

Mechanical systems are the common choice for transferring heavy and high-volume products in plants with a low transfer rate and short distances. However, when it comes to lighter products with smaller particle sizes, it is the pneumatic systems that stand out.

Mainly used in the transport of granular/powdered substances, pneumatic systems operate by transmitting the kinetic energy of the air stream moving in a line, creating an unbalanced environment within the pipeline using pressure. Thus, the product is pushed or sucked in the pipes connected to product feeding stations and then discharged. As air is a clean energy source and the system works in a completely closed environment, material losses and environmental pollution are significantly reduced.

Advantages of pneumatic systems

Depending on the existing needs and conditions, pneumatic systems offer significant advantages when designed by expert teams upon extensive examination, boosting work processes and overall plant efficiency:

Reduced maintenance as fewer moving parts are involved,
Increased work safety and flexibility,
Improvements in product quality and operational efficiency,
Reduction in product losses,
Tailored solutions with custom configurations to meet specific needs,
Easy cleaning,
Space and cost savings.

Pneumatic system components

Choosing the equipment that plays a role in the operation of pneumatic systems carefully prolongs system life and significantly enhances operational effectiveness and efficiency. The pneumatic group components used in many different parts of milling plants are categorized as below:

Valves and coils

Solenoid valves are used in controlling various fluids, such as water, air, steam, and gas. Consisting of coil-socket, sleeve-core, body-cover, and sealing elemants, these electromechanical automatic control valves are among the main components of industrial automation systems.

Pneumatic conditioners

Making the compressed air suitable for use in the pneumatic line, pneumatic conditioners play a critical role in system operation.

Pistons and equipment

Pneumatic cylinders (pistons, also known as air cylinders) generate a force in linear motion, using the power of compressed air. Equipped with a robust aluminum body, these mechanical devices offer a long service life, boosting system efficiency.

Air adjustment gates

Air adjustment gates, which can be connected to the automation system, enable automated operation for pneumatic doors. They make the air coming into the cyclones suitable for the system.

Electronic and pneumatic filter control units

Used to control the aspiration and pressure in jet filters in milling plants, these units enable a controlled and accurate operation in the system.

Limit switches

They are used for switching the power flow transmitted to the system on and off.

Pressure gauges

Enabling reliable and accurate measurement of the compressed air supplied to the equipment, pressure gauges have special measure ranges. They are manufactured in various sizes and pressure levels.

Pneumatic diverter valve with actuator

Working on the principle of utilizing the pressure generated by the gas taken into a chamber, pneumatic actuators, convert mechanical energy motion. Depending on the type of actuator that converts energy into mechanical motion, the motion may be rotary or linear. Pneumatic actuators are used for opening of closing valves, such as globe, butterfly, and directional control valves
