Macawber’s philosophy is a scientific approach to design with unmatched innovation and experience. They realize that every system is different and each company has different needs. Therefore, before they present any recommendations, Macawber carefully reviews the two major issues of any bulk handling system: material characterization and the system design objectives. The result? An optimized design for your individual needs, which addresses both technical and economic considerations, backed up with a wealth of experience.

A comprehensive, interlocking group of system types is required to meet the needs of a wide variety of applications in every process industry involving bulk materials handling. From pebble lime to peanuts, from coal to baby powder - and everything in between - Macawber has the technology, the hardware, and the experience to design and supply the proper technology group for reliability and life cycle economy.

Selecting the correct pneumatic conveying regime for your requirements is a vital decision for a successfully designed system. Almost all applications will benefit from a regime providing the heaviest line loading and the lowest material velocity. These attributes also provide the greatest conveying gas economies for efficient power consumption.

The Ashveyor® system is an effective low cost system for the transfer of ash or dust from a line of feed hoppers from Electro Static Precipitators (ESP) or baghouses. It is low cost and low profile and uses less energy than any other solution to multi-pickup point handling. The conveying vessel is a small casting with a heavy wall and is a simple low cost single piece item.

The well-proven Denseveyor® is a low velocity dense-phase conveying system assembly that is widely used throughout all process industries in all countries of the world.

The Sandpump® is a development of the Denseveyor® low velocity dense-phase conveying system. It is a value engineered system specifically for the special needs of sand only handling systems.

The Dome Valve ® is used in a wide variety of applications in almost every process. The unique closing and sealing action of the Dome Valve® enables continuous reliable operation where conventional valves fail to perform.

Super Denseveyor® Designed specifically for the neads of extreemly low velocity conveying to minimize material degredation over a limited distance.

Mini-Denseveyor® Designed specifically for smaller conveying rates, utilizing a heavy-duty cast body to save material and fabrication costs.
