Pneumatic Conveyors

The Macpump offered us is an arrangement of two pressure vessels that are based on working in an automatic and phased sequence to provide a continuous transfer of material with a high material pipeline loading for long conveying distances. The Macpump® is applied to mineral transfer applications where distance and tonnage rate requirements are high.

Variflow offered by us is a single, robust & automatic system that is used for maintaining material velocity & line loading where it should be, for the air source available. These Variflow® are also designed to successfully overcome the problems related to pipeline plugging from material velocities that are too low/ pipelines that are too heavily loaded in comparison to pressure potential available at the air source.

Denseveyor systems offered by us are ultimate solutions for the handling of difficult-to-convey materials; hot, abrasive & wet materials. These are also used for providing gentle handling of products that helps in preventing degradation of friable materials/ separation of blended materials. Its precision construction standards make it perfect conveying system for:

• Handling difficult-to-convey materials including abrasive, hot and/or wet
• Friable products (Preventing degradation & separation of blended materials)

Features:

• Smooth operations
• Low-velocity dense-phase pneumatic conveying of powders, granules & irregularly shaped materials
• Conveying done without degradation/ segregation
• System designed to successfully handle hot, wet, fine/ coarse, blended/ batched material

The Control Conveyor offered by us works on continuous, batch injection system. These systems effectively utilize unique and simple concept of materials metering into a gas stream that is also subjected to back pressure variations. This concept is widely applied to achieve outstanding reliability and accuracy in the involved processes.

The Dome Valve offered by us is used in a wide variety of applications in almost every industrial process. The unique closing & sealing action of this Dome Valve® also ensures continuous reliable operations especially in working environment where conventional valves fail to perform. Further, the dome component and seal is completely shielded from flow of material & crank shaft drive that allows unrestricted flow of material through the valve.

The range of sand pumps delivered by us is designed specifically for successfully meeting the dry sand conveying requirements. Based on proven dense phase pneumatic principles, these Macawber Sandpump® features simplified system controls, provision for air introduction and top discharge. These are designed specifically for meeting the specific application demands. Further, our process expertise also allows us to manufacture Sandpump® without custom modifications that ensure fast and easy installations.

Ash conveying system offered by us is a well proven method for the transferring of ash through standard pipelines at low velocity. Featuring virtually maintenance free designs, these systems have undergone continuous development that ensure in them highest efficiency & operational reliability. Further, all systems are backed by Macawber dense-phase technology that assure customers of the successful functioning of every ash type & combustion type system delivered from our end.

Work Process:

• A s h v e y o r ® operating sequence is very simple & relaxed
• Feature small cast iron vessels that do not require a vent valve, a level probe or discharge valve
• Each cycle clears away deposited ash from feed hopper leaving them normally empty
• Each line of A s h v e y o r s ® on each ESP field economizer or bag house cycle simultaneously transfer ash through a common pipeline
• Diverter valves for each feed point are not required & system controls are equally simple

Performance:

• A major coal fired utility of 2 x 300 Mega watt units
• Uses low quality coal with high ash content
• Requires 46 tons/hour design rate over 350 meters from ESP units
• Handling high temperature ash at 350⁰ C from the economizer
