In a method of coating a particulate material, a particulate material is fed into a mixing chamber. The particulate material is agitated within the mixing chamber and conveyed to a mixing chamber outlet. A coating is directed into the mixing chamber and the flow of the coating is controlled based on the volumetric flow rate of the particulate material into the mixing chamber. The coating includes at least one compound selected from herbicides, insecticides, nutrients, wetting agents, surfactants, fungicides, biologicals, inoculants, and mixtures thereof.

Functional treatment application to particulate materials such as mulch or potting soil

In a method of treating a particulate landscaping material, the material is fed into a mixing chamber and an additive mixture including a functional additive and a carrier is delivered to spray nozzles within the mixing chamber. At least one of the spray nozzles is operated to direct an atomized spray into the mixing chamber. The material is agitated within the mixing chamber during and/or after directing the atomized spray into the mixing chamber. The material is then conveyed with the additive mixture applied thereto to a mixing chamber outlet. During these steps, a volumetric flow rate of the particulate landscape material through the mixing chamber is intermittently determined. The determined volumetric flow rate is intermittently compared to a predetermined target flow rate of the particulate landscape material. Based on this comparison, the volumetric flow rate of the particulate landscape material through the mixing chamber is adjusted.

Apparatus and method for coating particulate material

A method and apparatus are defined for coating a particulate material. The apparatus includes a mixer having a mixing chamber. A quantity of particulate material is fed into an inlet of the mixing chamber. An agitator is provided for mixing and conveying the particulate material. A feed system is also provided for delivery of a coating into the mixing chamber. The coating is delivered as an atomized spray directed at the mixing particulate material within the mixing chamber. A controller is provided for adjusting the flow of the coating into the mixing chamber based on the volumetric feed rate of the particulate material.
