Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rigid mill having a rotary table and rollers, and more particularly to a rigid mill for adhesive material for smoothly crushing adhesive material.

[0002]

[Prior art]

 Conventionally, when crushing highly adherent materials such as clay, pigments, etc. into a rigid mill, some of the feed materials and crushed products adhere and deposit on the inner surface of the rigid mill. In some cases, the smooth milling action in the rigid mill may be hindered and sufficient milling efficiency may not be exhibited.

In order to avoid such adhesion and accumulation, for example, a scraping body is slidably provided inside a supply chute of a rigid mill (Japanese Utility Model Publication No. 2-9899).

In this type of rigid mill for adhesive materials, during scraping action, the scraping body is slid back and forth during mill operation to prevent the adhesive material from adhering and depositing inside the mill. I am allowed to do so.

[0005]

[Problems to be solved by the device]

 However, the above-mentioned conventional configuration is effective in preventing the adhesion and deposition on the inner wall of the supply chute in the rigid mill, but it is possible to prevent the adhesion material from adhering and depositing on the inner wall surface of the casing. It is not possible because it cannot be done.

When the scraping body is applied to the inner wall surface of the casing, the structure of the rigid mill is complicated and the crushing action during the mill operation may be hindered, which is not preferable.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and the adhesive material can be removed under a pneumatic structure without attaching a mechanical scraping body to the casing. It is an object of the present invention to provide a rigid mill for adhesive material, which can prevent the adhesive material from adhering to and deposit on the inner surface of the casing and can efficiently grind the adhesive material with a smooth grinding action.

[0008]

[Means for Solving the Problems]

 In order to achieve such an object, according to the present invention, in a rigid mill having a rotary table and a roller for crushing the adhesive material, an outer side for storing a crushing element composed of the rotary table and the roller is provided. A casing is erected, an inner casing made of a porous chamber material is provided inside the outer casing with an air chamber interposed, and air is blown into the mill from the inner casing.

[0009]

[Action]

 By doing so, during the operation of crushing the adhesive material of the rigid mill, air is blown into the inside of the mill from the inner casing made of the material of the porous chamber, so that the material is separated from each other and into the inner casing. The adhesive force of the adhesive material is significantly reduced, and it is possible to prevent some of the feed material and crushed material from adhering to and depositing on the inner casing, and efficiently crush the adhesive material under a smooth crushing action. can do. Further, since it is possible to intermittently blow the air into the inside of the mill, it is possible to reduce the amount of blown air.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a rigid mill for adhesive materials according to an embodiment of the present invention. In FIG. 1, a compact mill 10 has a rotary table 12 which is a crushing element and a roller 14 driven by the table 12 stored in an outer casing 22. The rotary table 12 is rotated by a drive unit 16. The roller 14 is adapted to actuate the pressing means 20 to press the rotary table 12 forming the material layer through the supporting member 19 tilted around the support shaft 18, and to press the material. A supply pipe 34 having a supply port 36 is provided, and a classifier 38 is mounted below the ceiling portion 28 of the outer casing 22.

A rotating force is applied to the classifier 38 via a transmission member 40 that is rotated outside the supply pipe 34. Reference numeral 30 denotes a support member, which is fixed above the ceiling portion 28, and a transmission member 40 is rotatably supported via a bearing 39. Reference numeral 56 is an inlet for air or the like introduced into the crushing chamber 54.

The outer casing 22 is formed by vertically arranging a cylindrical straight tubular portion 24 in the lower portion, an inverted conical intermediate portion 26 in the upper portion, and a ceiling portion 28 in the upper portion, and is used as a constituent material. Is usually a steel plate or the like.

The inner casing 42 is provided inside the outer casing 22 via an air chamber 52, and faces the straight tubular portion 24, the intermediate portion 26, and the ceiling portion 28, and the straight tubular member 44 of the inner casing 42, the intermediate portion 42, and the intermediate portion 26. A member 46 and a ceiling member 48 are arranged over the entire surface, and a porous material such as campus or a perforated steel plate is used as a constituent material.

Reference numeral 50 denotes a fumes connecting pipe mounted below the straight cylindrical portion 24, which is connected to the air pipe and blows air from the entire surface of the inner casing 42 into the rigid mill 10 through the air chamber 52. Is being done.

For blowing air into the mill 10, a control valve (not shown) is provided in the fumes connecting pipe 50 so that the air can be operated continuously or intermittently, and further, the blowing air amount and the blowing time can be adjusted. The optimum operating condition is obtained. It is also preferable to use dehumidified air as the blowing air.

Next, the operation will be described. With the operation of the compact mill 10, the adhesive material is supplied from the supply port 36 to form a material layer between the rotary table 12 and the roller 14 to perform a crushing action, and the air from the introduction port 56 is removed. Under the introduction, the crushing chamber 54 is brought into a fluidized state, and the crushing action between the rotating table 12 and the roller 14 is circulated, and the particle size is successively reduced.

The crushed product rises in the crushing chamber 54 and reaches the classifier 38, where it is classified and separated into coarse particles and fine particles. The fine particles are accompanied by the air flow and exhausted from the exhaust port 32. Then, the coarse particles are again settled in the crushing chamber 54 and the crushing operation is repeated.

Under the above-mentioned crushing action, a part of the feed material and the crushed product made of the adhesive material starts to adhere to each other and to the inner casing 42, but is introduced from the fumarolic connection pipe 50. The air is blown out through the air chamber 52 from the entire surface of the inner casing 42 made of the porous chamber material into the rigid mill 10, and the air is blown between the material particles or between the material particles and the inner casing 42. By acting to reduce the adhesive force of each, the adhesion / accumulation on the surface of the inner casing 42 is prevented.

In addition, the swelling and deformation of the inner casing 42 is repeated due to the intermittent blowing of air, so that the material particles that have started to be in the adhered state are exfoliated to prevent the adherence / accumulation on the surface. The amount of air blown out can be reduced as well as being promoted.

Thus, the circulating flow of the material and the air in the rigid mill 10 can form a continuous flow without causing a stagnation such as adhesion and deposition of the material, and thus is a sticky material. Regardless, it can be efficiently crushed under a smooth crushing action.

[0021]

As described above, according to the present invention, air is blown into the rigid mill from the inner casing made of a porous material without mounting a hammering device on the outer side of the casing, thereby adhering the adhesive material. Can be prevented from adhering to and depositing on the surface of the inner casing, and the adhering material can be efficiently crushed under a smooth crushing action, which is very effective.
