A shaped abrasive particle including a body having a first major surface, a second major surface, and a side surface joined to the first major surface and the second major surface, and the body has at least one partial cut extending from the side surface into the interior of the body.

[Solution] Provided is a plant-derived water purifying agent used for water purification for industrial wastewater, etc. and including a granulated product of a plant powder, such that when a wastewater purifying treatment using the plant-derived water purifying agent is performed by an automated purifying treatment device, the water purifying agent can be suitably used in the automated purifying treatment device. It is more preferable that a Carr's fluidity index of the water purifying agent obtained by measuring 3 items of the water purifying agent, which are an angle of repose, a degree of compression, and a spatula angle be 40 or greater.

A device for granulating coarse material is disclosed herein. Examples of course material include pulverulent solids such as powder, grain, or mixtures thereof. The device includes a rotor, a screen, and an automatic distance adjusting unit. The rotor is configured to rotate/oscillate and press the coarse material through the screen in order to produce a granulate with a smaller granulate unit size compared to the coarse material. The automatic distance adjusting unit is configured to adjust a distance between the rotor and the screen.

The manufacturing method includes a granulation step. The granulation step is a step of forming a plurality of granules by performing extrusion granulation on a granulation material using a granulation machine. The granulation machine includes a die and a roller. A through hole that allows the granulation material to pass therethrough is formed in the die. The roller pushes the granulation material into the through hole while rolling on the surface of the die. In the granulation step, low-speed pushing in which the granulation material is pushed while the roller rolls at a first speed, and high-speed pushing in which the granulation material is pushed while the roller rolls at a second speed that is higher than the first speed are executed.

The present disclosure provides a process. The process includes (i) melt blending, in an extruder, (a) a polyolefin phase and (b) an aqueous phase in the presence of (c) at least one dispersant selected from an acrylic dispersant, a poloxamer dispersant, and combinations thereof; (ii) producing an interfacial tension from 0.1 dynes/cm to 25 dynes/cm; (iii) forming a polyolefin aqueous dispersion having from 25 wt % to 90 wt % solids content of dispersion; and (iv) removing the water from the polyolefin aqueous dispersion to form a powder. The powder has a mean volume average particle size from 10 m to 300 m, a sphericity from 0.92 to 1.0, a particle size distribution from 1 to less than 2, and a particle density from 98% to 100%.

A pelletizing system including a supporting rail, a pelletizer that is suspended from the supporting rail, a suspension base, a supporting arm, and an articulated arm. The supporting arm is supported at a first end on the suspension base by means of a first swivel joint and is hinged to the supporting rail at a second end by means of a second swivel joint. The articulated arm includes a first articulated arm branch which is connected to a second articulated arm branch by a third swivel joint. The first articulated arm branch is supported on the suspension base by means of a fourth swivel joint, and the second articulated arm branch is hinged to the supporting rail by means of a fifth swivel joint. In an embodiment, the first through fifth swivel joints each have an essentially vertical swivel axis.
