Magnetic powder water mill with rotary pieces

Abstract

The invention discloses a magnetic powder water mill with rotary pieces. The magnetic powder water mill with the rotary pieces comprises a container (1) and a water mill rubber wheel (2). The water mill rubber wheel (2) is arranged in the middle of the container; the bottom end of the water mill rubber will (2) is connected with the inner wall of the bottom of the container (1); and a plurality of rotary pieces (3) are arranged on the lateral wall of the water mill rubber wheel (2). According to the magnetic powder water mill with the rotary pieces, because the rotary pieces are arranged on the lateral side of the water mill rubber wheel, grinding balls and a magnet are prevented from gathering at the bottom of the container because of being driven by the rotary pieces, the collision and friction speed of the grinding balls and the magnet is increased and accordingly production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of magnetic force sensing, and in particular relates to a magnetic powder water mill provided with a rotor. Background technique [0002] In the process of preparing magnet particles, magnetic powder water mills are often used. In the past, magnetic powder water mills used the principle of vibration to break a large magnet into multiple small magnets. However, due to the effect of vibration, most cases can only It takes a long time to split the magnet into small magnet pieces, and it takes a long time to obtain smaller magnet particles; or to crush the magnet into magnet particles by direct crushing and crushing, the rolling force is not easy to control, and the obtained If the magnet particles are too small and become powder, they will be mixed into the air and pollute the working environment.

[0002] In the process of preparing magnet particles, magnetic powder water mills are often used. In the past, magnetic powder water mills used the principle of vibration to break a large magnet into multiple small magnets. However, due to the effect of vibration, most cases can only It takes a long time to split the magnet into small magnet pieces, and it takes a long time to obtain smaller magnet particles; or to crush the magnet into magnet particles by direct crushing and crushing, the rolling force is not easy to control, and the obtained If the magnet particles are too small and become powder, they will be mixed into the air and cause pollution to the working environment

The effect of the magnetic powder prepared by the rotary water mill is good, but during the operation of the magnetic powder water mill, it is necessary to continuously add magnets, balls and water to the container. It will gradually settle to the bottom of the container, and the rotation of the container is more difficult to drive the material at the bottom of the container to rotate, thus weakening the effect of the grinding ball and the magnet. In order to make the grinding ball and the magnet rub to obtain the required magnet size, it takes a lot of time. reduced production efficiency
