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.

A device for spherification of a liquid includes a first device for storing a first liquid; and a spherification tank for storing a second liquid, arranged so that a dripper or entry funnel controls a level of the second liquid in the spherification tank. A device meters the first liquid coming from the first tank into the spherification tank. An extraction device extracts spheres generated in the spherification tank as a result of the metering. The extraction device includes a worm screw located in the spherification tank, the worm screw being arranged at an angle to the level, and a motor for rotating the worm screw.

An abrasive grain is disclosed and may include an elongated body. The body may define a length (l), a width (w), and a height (h), where the length is the longest dimension. The elongated body may have a first end face, a second end face, and a side surface extending between the first end face and the second end face. The body can include a twist along an axis body.

A method of treating a powder material includes classifying a powder material within a vessel by using a fluidized bed of the powder material to separate smaller particles of the powder material from larger particles of the powder material, and degassing the separated smaller particles and the larger particles within the vessel by heating and fluidizing the larger particles and the separated smaller particles.

Various shaped abrasive particles are disclosed. Each shaped abrasive particle includes a body having at least one major surface and another surface extending from the major surface.
