Manufacturer of calcinated Rice Hull Ash. Product utilization is the primary responsibility of Agrilectric Research. The rice hull ash (RHA) produced by Agrilectric is approximately 20% of the rice hulls consumed in the combustion process. While this reduction is significant, the quantity of production cannot be left to chance for any one market area.


Agrilectric Research manufactures and sells high performance, renewable filter aids for all types of solid liquid separation applications. Our filter aids are superior to traditional products and deliver extraordinary value in sludge dewatering operations as well as high purity, high volume filtration applications. Agrilectric Research has developed a number of innovative filter aid technologies.

Additive & Insulator

Agrilectric has supplied the world wide steel industry since the start up in 1984. The unique characteristics of the rice hull ash (RHA) make it an exceptional insulator.

With the percentage of unburned carbon in the range of 4 to 6% and low crystalline silica values, the ash is used as insulator in the steel manufacturing process without fear of flaring up due to the unburned carbon igniting and causing heat production in an area that is not intended to produce heat. The Agrilectric combustion technology has been producing ash products for over 20 years with the customers knowing they will receive consistency in product quality.

When used as a Ladle or Tundish Cover, the rice hull ash:

Prevents Heat Loss
Extends Pouring Time
Maintains Core Temperature
Improves Yields from the Ladle
Provides a low density Insulation
Prevents Surface Oxidation
Coagulates Slag Carry Over from the Ladle
Reduces Metal Skulling
Requires Less Tundish Heat While Casting
Eliminates Tundish Covers
Physical & Chemical Properties are Completely Compatible

Unburned Carbon: Average 5%
Silica Content: Average 93%
Moisture: Average <3%
