Abstract

PROBLEM TO BE SOLVED: To realize the efficient crushing and mixing operation by a vibration mill by installing a vibration means which is filled with a medium for crushing or mixing, on a drum supported elastically by a mounted spring. SOLUTION: A drum 1 with a spring 5 is elastically supported on a frame 6 and is with media 4 of stainless steel, ceramic or the like such as a ball, a rod and a cylinder for the purpose of crushing and mixing. In addition, the drum 1 is equipped with a vibrating means 3. Further, a weight 2 is attached to the drum 1 to keep the drum 1 well balanced mechanically. A rotary power is transmitted to the vibrating means 3 by a motor 10 through universal joint 11 so that a vibration is generated. Thus it is possible to enhance the crushing and mixing efficiency of the vibrating mill and further, simplify its operating structure and reduce its weight to contribute to the saving of a required power.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a vibration mill for crushing or mixing an object to be crushed or an object to be mixed.

[0002]

2. Description of the Related Art A conventional vibrating mill has vibrating means (Japanese Utility Model No. 61-95442, Japanese Utility Model Application No. 61-130) on both sides of a drum.
90) was generally used. There was no baffle provided inside the drum.

[0003]

Problems to be Solved by the Invention
The mixing efficiency was not always good because the vibrating means had two lines, the structure was complicated, and there were no baffles in the drum.

[0004]

Means for Solving the Problems As a means for simplifying and reducing the weight of the vibration mill, this problem is solved by using the vibration means on one side of a drum. In addition, a baffle plate is mounted inside the drum as a means for increasing the efficiency of grinding and mixing of the vibration mill.

[0005]

According to the present invention, the vibration means is provided on one side of the drum like the vibration mill, so that the vibration mill can be simplified and reduced in weight, thereby reducing the manufacturing cost and the required power. In addition, by placing a baffle plate in the drum, the efficiency of pulverization and mixing increases.

[0006]

Embodiments of the present invention will be described. As shown in FIGS. 1, 2, 3, 4, and 5, an elastically supported drum 1 provided with a spring 5 is filled with a medium 4 for crushing or mixing, and a vibration means 3 is attached. Is activated by the electric motor 10, the medium 4 filled in the drum 1 moves. The medium is steel, stainless steel, ceramic, such as balls, rods, cylinders, etc.
Use etc. Weight 2 for mechanical balance
To the drum. In the illustrated example, rotational power is transmitted from the electric motor 10 to the vibration means 3 through the universal joint 11 to generate vibration. As a method of generating the vibration, a vibration motor which itself becomes the vibration means 3 can be used instead of using the electric motor 10.
In this case, the electric motor 10 and the universal joint 11 become unnecessary. As shown in FIG. 5, as the size of the drum 1 increases, the vibrating means 3 and the weight 2 also have their scores depending on the size of the drum 1 and the weight of the medium filled therein. The size will be set to meet the required power. The raw material supply port 8 and the discharge port 9 are provided above one end of the drum 1, but the mounting positions of the raw material supply port 8 and the discharge port 9 are not necessarily fixed positions. Further, a baffle plate 7 is provided inside the drum 1.
To provide the medium 4 filled in the drum 1
Can be exercised strongly. The baffle 7
Although the example shown in FIG. 3 has a three-sheet configuration, there may be two or three or more pieces. It is also conceivable to insert the baffle plate 7 in a free state without fixing it to the drum 1 or to fix it inside the drum 1.

[0007]

The vibration mill in which the vibrating means is attached to only one side of the drum has a low manufacturing cost because the number of parts constituting the machine is small, and the weight of the machine is lower than that of the conventional vibrating mill having the vibrating means on both sides. The running cost is also reduced because the weight is reduced by about 20%. On the other hand, by providing a baffle plate inside the drum of the invention, the efficiency of crushing or mixing the material is increased.
