Aerators Solve Material Flow Problems In Bins and Silos
Monitor Technologies LLC offers a broad line of aerator devices that solve a variety of bin flow problems associated with difficult powders. Monitor's product line consists of the highly popular Rectangular Air Pad, Evasser and Flo-Pad products. These devices offer different shapes and pressure ratings and provide different methods of diffusing the air. With almost five decades of experience in bulk solids applications Monitor Technologies application engineers are highly qualified to recommend the most cost effective solution available.
The Air Pad, Evasser and Flo-pad products are alternatives to using high impact pneumatic or electric vibrators that can be loud and cause damage to the bin and surrounding equipment. In fact, bin vibrators can pack material instead of fluidizing it to address the problem. Typically used in applications where the material flow into the bin is via pneumatic conveying, the entrained air in the material is evacuated during the settling of the powder material. Bin vibrators actually facilitate this de-aerating and can create packing flow problems.
Using aerators, the source of the problem (de-aerated material) is addressed and a gentle and cost effective solution is ensured. In addition, many configurations of these bin aerators can be mounted from outside of the bin, thereby simplifying installation.

SiloPatrol® SE Measuring coal powder levels when nothing else will work ….
Coal-fired power plants are commonplace around the
world. In order for these power generating stations to create
huge amounts of electricity the turbines need to be feed with steam
and the steam created by boilers that are fired by … yep,
coal. But coal as it comes from the mining operations is not
what is fed to the burners. First it is ground or pulverized
into powder. It is not unusual for the coal powder to be stored
in silos awaiting the demand for it to be fed to the burners. The
inventory of coal powder in these silos needs to be monitored to
allow for efficient operation of the power plant.
So, how do we monitor the inventory of coal powder in a silo? Not
easily. In one typical application the power plant personnel
found that the only technology that would work reliably is the modern
smart weight & cable system from Monitor Technologies LLC, the
SiloPatrol® SE.
Anhui Tongling power plant in Anhui province in China had tried
almost ever technology possible to get a reliable level measurement
in their 5 coal powder silos. Radar, ultrasonic and others
were tried, but none worked reliably. It wasn’t until
Beijing Conasen walked in and proposed that the Tongling plant use
the SiloPatrol SE smart cable-based inventory monitoring system that
the power plant personnel found a reliable solution.
Mr. William Yuan, sales manager for Beijing Conasen indicates that
the power plant tried many major brands of ultrasonic, radar, and
other technologies but that due to good relations with the Tongling
plant personnel he was able to sell three SiloPatrol SE model SMU
sensors and an HMI operator interface to them. The units were
installed by plant personnel. Because of the heavy amount of
coal dust in the silos an air purge using dry compressed air was
used. The SiloPatrol sensor incorporates the patent-pending
use of Hall-effect sensor technology, a split-compartment enclosure,
microcontroller, redundant optics and many other valuable features
and technology to ensure reliable measurement even in challenging
dust applications like coal powder.
The SiloPatrol SE system has been working reliably and the plant
has since purchased two additional sensors and connected them into
the same HMI operator interface. This same sensor technology
is working reliably at other coal-fired power stations in China as
well.
