Layered particle electrostatic deposition process for making a coated abrasive article

A method comprising:

• moving a coated backing though an electrostatic field above a conveyor belt;
• and
• moving a first layer of particles positioned on a second layer of particles sitting on the conveyor belt through an electrostatic field;
• and
• wherein the first layer of particles is different in at least one property from the second layer of particles.

A system comprising:

• a conveyor belt moving though an electrostatic field;
• a coater applying a make coat onto a backing;
• a web path guiding a coated backing through the electrostatic field above the conveyor belt and the make coat on the backing is positioned facing the conveyor belt;
• a first particle feeder applying a first particle layer over a second particle layer on the conveyor belt;
• a second particle feeder applying the second particle layer onto the conveyor belt located before the first particle feeder with regard to the conveyer belt's direction of travel;
• and
• wherein the conveyor belt moves the first particle layer and the second particle layer though the electrostatic field transferring at least some of the first and second particles to the coated backing from the conveyor belt.
