Enclosures for vertical pulverizer systems are disclosed. The enclosure may include a vertically oriented cylindrical body forming an internal cavity. The enclosure may also include a cover positioned above the cylindrical body. The cover may have a curved surface. Additionally, the enclosure may include an inlet channel formed through the cover, where the inlet channel may be in fluid communication with the internal cavity of the cylindrical body, and an outlet channel formed through the cover, adjacent the inlet channel. Furthermore, the enclosure may include a base component positioned within the internal cavity of the cylindrical body, opposite the cover, the base component having a curved surface, a journal opening formed through the cylindrical body between the cover and the base component, and a journal opening cover coupled to the cylindrical body. The journal opening cover may cover the journal opening.

A wear-resistant element for partial insertion into a recess on the surface of a wear area of a comminuting device. The wear-resistant element includes particles made of a highly wear-resistant material which are embedded in a matrix material.

This invention relates to methods of preparing nanotherapeutic compounds and compositions comprising nanotherapeutic compounds. The nanotherapeutic compounds prepared according to the methods provided herein are useful for the treatment of disease, for example, cancer, in a subject in need thereof.

A system for adjusting a depth of a material bed in a pulverizer mill is provided. The system includes a rotatable bowl, an extension ring, and an extension mechanism. The rotatable bowl has a surface operative to support the material bed while the bowl rotates such that particles of the material bed are pulverized against the surface by one or more grinding rollers of the pulverizer mill. The extension ring is disposed about a circumference of the rotatable bowl extending away from the surface and defines a depth of the material bed. The extension mechanism adjusts at least one of the extension ring and the rotatable bowl while the rotatable bowl rotates. Adjusting at least one of the extension ring and the rotatable bowl via the extension mechanism moves the extension ring in relation to the surface so as to adjust the depth of the material bed.

A tool for a food processor has a first member driven in rotation and a second stationary member which have complementary working surfaces for rolling engagement formed of a stone-like material for working ingredients into a thin paste-like form, the surfaces being conical or cylindrical.

A mill roller (6) is provided with a roller main body (62) that rotates about an inclined axis line (O2) and has an outer peripheral surface (64) for pulverizing an object to be crushed against the mill table (4). The outer peripheral surface (64) is convex outward in a radial direction of the roller main body (62). The outer peripheral surface (64) has a first outer peripheral surface (641) and a second outer peripheral surface (642). The first outer peripheral surface (641) has an arcuate shape formed to have the same radius of curvature on both sides of a maximum outer diameter point (A). The second outer peripheral surface (642) is further receded inward in the radial direction than an imaginary circle running along the first outer peripheral surface (641).

A variable orifice for a pulverized coal pipe of a pulverizer includes a pipe body connected to and installed on a pipeline of the pulverized coal pipe for supplying a pulverized coal from the pulverizer to a boiler and including a diameter expansion portion having a diameter expanded more than a diameter of the pulverized coal pipe; an opening and closing portion installed inside the diameter expansion portion of the pipe body; a rotation actuating portion configured to rotate the inner opening and closing plate and the outer opening and closing plate in mutually different directions; and an opening and closing plate protection member coupled to an inner circumferential surface of each of the inner opening and closing plate and the outer opening and closing plate.

A mill for crushing a bed of materials by compression includes: a horizontal-axis cylinder the interior wall having a runway track for a crushing roller placed inside the cylinder, a unit rotating the cylinder at a speed that spins the material outward, the crushing roller, a unit for pressing the crushing roller against the runway track of the cylinder, an inlet for supplying material for crushing at one end of the cylinder and an outlet for crushed material at the other end, a unit for controlling the movement of the material so it travels over only a fraction of the length of the cylinder in each revolution and passes between the cylinder and the roller several times before reaching the outlet. The runway track is followed by a downstream lip opposing material flow, downstream of the crushing roller in the direction in which the material travels.

A crushing mill with a single roller inside a driven cylindrical shell inner surface, both with horizontal and parallel but offset axes is disclosed. In some embodiments, the roller has protrusions such that as the roller and shell rotate rock or other material may be crushed between the shell and the roller, respectively. In some embodiments, the shell and the roller each have surface protrusions such that rock or other materials may be crushed between the shell and the roller as they rotate. In some embodiments the shell and the roller operate at differential speeds with respect to each other to induce shear forces on the material to be crushed.
