Description
Technical Field
The invention belongs to the technical field of grinding, and mainly relates to a high-speed flowing ball mill.
Background
The high-speed flow ball mill is used for grinding materials by virtue of rolling force and shearing force between high-speed flow grinding media, and the fineness of the ball mill is dozens of micrometers to less than one micrometer;
however, the ball mills used at present continuously rotate in one direction at a constant rotating speed, when the mill cylinder rotates, the milling media are lifted to the upper part of the milling chamber and then fall freely, impact is generated on the materials, the lower milling media and the lower lining plate, and due to overlarge impact instant stress, the load overload on the materials to be milled is caused, most of energy is converted into heat energy and noise, and the energy utilization rate is low;
meanwhile, the ball mill has critical rotating speed, and when the rotating speed exceeds the critical rotating speed, the milling media are attached to the inner wall of the milling cavity and do not move relative to the milling cavity, and the ball mill cannot work, so that the flowing speed of the milling media of the ball mill cannot be increased, the rolling speed and the shearing speed cannot be increased, the grinding energy is weak, and the energy density per unit volume is small and is 18-20kw/m3。
The filling rate of the grinding medium in the grinding chamber of the continuous ball mill is less than 45 percent, and the space utilization rate is low.
Disclosure of Invention
In order to solve the technical problems, the invention aims to disclose a high-speed flowing ball mill.
The invention adopts the following technical scheme:
a high-speed flowing ball mill is characterized in that one or more swing driving mechanisms are connected to the outer surface of a powder grinding chamber with a swing center or a power shaft, and drive the powder grinding chamber to swing left and right in a reciprocating manner around the swing center; the two pushing plates are both positioned at the lower part of a horizontal line passing through the swinging center and are respectively positioned at two sides of a vertical line passing through the swinging center of the grinding chamber; one ends of the two pushing plates are connected and closed into an integral structure on a vertical line passing through the swinging center of the grinding chamber, the other ends of the two pushing plates are respectively connected and closed with the inner surface of the grinding chamber on two sides of the vertical line of the swinging center of the grinding chamber, and the pushing plates are arranged along the axial direction, namely the length direction, of the inner cavity of the grinding chamber and are connected and closed with the inner wall surfaces of two axial ends of the grinding chamber; the pushing plates positioned on two sides of the vertical line of the swing center of the grinding chamber are connected to form an integral plate surface which serves as the bottom surface of the inner cavity of the grinding chamber, and the grinding chamber cavity positioned at the lower part of the pushing plates and the grinding chamber cavity positioned at the upper part are isolated and sealed; the pushing plates located on two sides of the vertical line passing through the swing center of the grinding chamber are protruded towards the direction of the swing center, and the highest point of the whole plate surface formed by connecting and closing the two pushing plates is located on the vertical line passing through the swing center of the grinding chamber.
The two pushing plates in each inner cavity are identical in shape and are arranged in bilateral symmetry along a perpendicular line passing through the swing center of the powder grinding chamber.
The shape of the integral plate formed by connecting and closing the two pushing plates in each inner cavity is an arc surface.
The shape of the integral plate surface formed by connecting and closing the two pushing plates in each inner cavity is a curved surface.
The straight line connecting the two pushing plates with the connecting closed parts at the two sides of the inner surface of the grinding chamber is parallel to a horizontal line passing through the swing center of the grinding chamber, and the vertical distance between the two pushing plates is 0.6-0.95 times of the radius of the inner cavity of the grinding chamber, preferably 0.75-0.85 times of the radius of the inner cavity of the grinding chamber.
The height of the protrusions of the two pushing plates towards the direction of the swing center is 0.001-0.1 time of the radius of the inner cavity of the grinding chamber, and preferably 0.005-0.01 time of the radius of the inner cavity of the grinding chamber.
The positions, sizes and shapes of the push plates in the cavities of the two adjacent grinding chambers are the same.
The position, the size and the shape of the push plates in the cavities of the two adjacent grinding chambers are different.

The flow speed of the grinding media and the materials in the cavity of the grinding chamber can be adjusted by changing the swing frequency and the swing angle of the swing driving mechanism, and the higher the swing frequency and the larger the swing angle are, the higher the flow speed of the grinding media and the materials is.
