Main principle:
The vertical eccentric pendulum shaft is adopted. When the motor is running at high speed, the vibrating platform eccentrically swings, generating a certain centrifugal force and inertial force moving in the direction of rotation, driving the three tanks on the platform to perform three-dimensional movement up and down, left and right, and back and forth, and the grinding balls in the tank correspond to Do three-dimensional movement, high-speed impact on the tank wall to grind the sample, and the heat generation ratio is low, the milling energy input is 2-3 times higher than the traditional planetary two-dimensional movement.
The sample realizes mechanical alloying in a very short time to form nano ultrafine powder or amorphous material.
Application range:
Grinding of trace and small samples in laboratories of major universities and research laboratories in biology, chemical industry, materials, construction, environment, geology and mining, pharmaceuticals and other industries;
Mechanical alloying and new material development in electronics and materials industries;
Various industries, dry and wet ball milling or mixing various solids, suspensions and pastes with different particle sizes and materials.
Design Features:
○Vertical eccentric shaft design, three-dimensional movement of the tank
○It can grind three different materials at the same time, with good synchronization and repeatability
○The instrument has a stable center of gravity and a double-layer design to prevent the phenomenon of "off-tracking" during the grinding process
○Tensile spring balance system to prevent damage to the vibration platform caused by huge impact
○Asynchronous motor to ensure continuous operation of the instrument for up to 72 hours
○The tank body is sealed, which can realize dry and wet grinding and mixing
○The tank can be immersed in liquid nitrogen to realize low-temperature grinding
