Which achieved success in distributing Uniformity of fine particles passing through a rotary sorter to a fine particle outlet channel Which is at four points When conveying pulverized coal in a roller mill with an air stream, the roller mill structure is characterized by the release of pulverized coal obtained by crushing raw coal. It is inserted into the mill body (11) from the fine particle outlet (14) formed on the top of the mill body. In order to separate into four parts In the direction along the line Around the circle to the outside by air flow. The structure of the roller mill includes a platform which rotates in the crusher body (11), three rollers for rotating on that platform and crushing raw coal and a rotary screener (20) on the origin side of the channel. The fine particle outlet (14), where the movable impeller (21) for the narrow part of the flow channel cross-sectional area, is provided at the midpoint of the flow channel for the stream of fine particles flowing into the section. Inside of Rotary separator (20) and further to the fine particle outlet (14) Conclusion 10/06/15 provides a roller mill structure.

The structure of the roller mill consists of a platform which rotates in the mill body (11), three rollers for the upper rotation only. And crushed raw coal And a rotary sorter (20) located on the source side of the fine particle outlet (14) where the movable impeller (21) for partially narrowed the cross-sectional area of the flow channel was provided. At the midpoint of the flow channel for a stream of fine particles flowing in In the interior of the rotary sorter (20) and on to the fine particle exit channel (14).

Claims (5)

Revised 10/06/58 1. The structure of a roller crusher is designed to release fine particles obtained from crushing the material to be crushed, which are fed into the crusher body, from a number of particle outlets formed on the outer end of the crusher, to be separated in a circumferential direction to the outside by air conveyance. The structure of such a roller crusher consists of: a shaped platform that rotates inside the crusher body; a number of shaped rollers that rotate on the platform and crush the material to be crushed; and a rotary separator positioned directly at the upstream end of the particle outlet, where correction devices for partially narrowing the cross-sectional area of the flow channel are provided within the rotary separator at the center of the flow channel for the stream of fine particles to flow into the interior of the rotary separator and continue towards the particle outlet, where several correction devices rotate independently and where some correction devices are shaped with damping elements. 1. A number of panels rotating around a vertically driven rotating shaft mounted on the side wall of the rotary separator to correct the cross-sectional area of the flow channel. 2. The structure of the roller crusher according to claim 1, in which the fine particle outlet channels are separated circumferentially and positioned adjacent to each other on the roller crusher structure, and a number of correction devices are arranged between the fine particle outlet channels. 3. The structure of the roller crusher according to claim 2, in which the rollers are arranged symmetrically axially relative to the fine particle outlet channels. 4. The structure of the roller crusher according to claim 1, in which the rollers are arranged symmetrically axially relative to the fine particle outlet channels. 5. The structure of the roller crusher according to claim 1, in which a number of correction devices, each shaped to rotate over a range from a position with the smallest far channel cross-section which significantly corresponds to the diameter passing through the axial center of the flow channel. The rotary sorter reaches the second position with the largest cross-sectional area of the flow channel, which is then significantly rotated 90 degrees to the left around its axis of rotation. 1. The structure of a roller crusher is designed to release fine particles obtained from crushing the material to be crushed. These particles are fed into the crusher body and exit through a number of particle outlets formed on the outer end of the crusher. They are then separated in a circumferential direction to the outside by air conveyance. The crusher body consists of: a rotating platform; several rollers that rotate on this platform and crush the material; and a rotary separator located upstream of the particle outlet. A correction device for partially narrowing the cross-sectional area of the flow channel is provided at the center of the flow channel for the fine particle stream to flow into the interior of the rotary separator and then to the particle outlet. 2. The structure of the roller crusher according to claim 1, in which the correction device operates to allow for the correction of the cross-sectional area of the far channel. 3. The structure of the roller crusher according to claim 1 or 2, in which the correction device is arranged between separate fine particle outlets along the circumference and in adjacent positions. 4. The structure of a roller crusher is designed to discharge fine particles obtained from crushing the material to be crushed. These particles are fed into the crusher body through a number of particle outlets formed on the top of the crusher body, where they are separated in a circumferential direction to the outside by air conveyance. The crusher body consists of: a rotating platform within the body; several rollers for rotation only, crushing the material to be crushed; and a rotary separator located at the opposite end of the particle outlet, which feeds a portion of the air-conveying fluid from the outer surface of the rotary separator, positioned on the inner upper part of the crusher body, into the crusher body. 5. The structure of a roller crusher as described in any of the claims 1 through 4, in which the rollers are arranged symmetrically axially to the fine particle outlet.
