Various shaped abrasive particles are disclosed. Each shaped abrasive particle includes a body having at least one major surface and a side surface extending from the major surface. The side surface can includes a toothed portion. The toothed portion can comprise a plurality of teeth. Each one of the teeth can have the same height.
ABRASIVE PARTICLES HAVING AN ELONGATED BODY COMPRISING A TWIST ALONG AN AXIS OF THE BODY
An abrasive grain is disclosed and may include a body. The body may define a length (l), a height (h), and a width (w). In a particular aspect, the length is greater than or equal to the height and the height is greater than or equal to the width. Further, in a particular aspect, the body may include a primary aspect ratio defined by the ratio of length:height of at least about 2:1. The body may also include an upright orientation probability of at least about 50%.

Preparing and storing a free flowing frozen supplementary product
A method of preparing and storing a free-flowing frozen supplementary product, including preparing a supplementary composition for freezing, dripping the supplementary composition into a freezing chamber, freezing the dripped supplementary composition into beads, and transporting the frozen beads by conveyor belt out of the freezing chamber.

Process to produce nanoparticles
A process for producing nanoparticles of a substance, including in a first chamber, forming a dispersion of a substance in a fluid and bringing the fluid into a supercritical state; passing the dispersion from the first chamber through a cooling device or into a cooling zone in a second chamber, wherein the cooling device or cooling zone configured to reduce temperature of the dispersion below a temperature at which the fluid forms solid particles such that nanoparticles of the substance are formed, wherein the second chamber comprises a surface configured to receive the solid particles of the fluid and the nanoparticles of the substance; allowing pressure to decrease and/or temperature to increase in the second chamber to transform the solid particles into a gaseous state, removing the fluid in the gaseous state and with the nanoparticles remaining on the surface; and collecting the nanoparticles from the surface.

APPARATUS AND METHOD FOR GRANULATING LOW VISCOSITY MATERIALS
An apparatus to batch or continuously form solid polymer particles, the apparatus comprising the following components: A) at least one pastillation unit comprising a pastillation head, said unit used to form discrete molten polymer particles from a polymer melt; B) a moving belt to receive and transfer the discrete molten polymer particles from the pastillation head; C) a means to transfer water onto the moving belt, such that the water comes into contact with the discrete molten polymer particles on the moving belt to form the solid polymer particles; and wherein the water of component C is sprayed onto the discrete molten polymer particles, such that the ratio of “the rate of water spray” to “the discharge rate” is ≥3.0; and wherein the belt residence time is ≤50 seconds.
