Product Description
Laboratory mixer-grinder is a kind of equipment used for scientific
research, teaching or small-scale experiments to evenly mix, grind
and refine materials. Its core function is to make different
materials fully contact through mechanical forces (such as
stirring, rolling, shearing, etc.) to achieve component
homogenization, particle size refinement or physical and chemical
property modification. It is widely used in materials science,
chemistry, geology, pharmacy and other fields.
Main types and working principles
According to the working principle and structural characteristics,
laboratory mixer grinders are mainly divided into the following
categories:
1. Stirring Mixing Mill
Principle: The rotating impeller (such as paddle, anchor, turbine)
exerts shear force and convection on the material to disperse and
mix the particles. Some equipment can be equipped with grinding
beads (such as glass beads, ceramic beads) to enhance the grinding
effect.
Features: Simple operation, suitable for mixing liquids, slurries
or low-viscosity materials. The mixing efficiency is affected by
the rotation speed, blade shape and material viscosity.
Applications: coating preparation, ink mixing, nanomaterial
dispersion, etc.
2. Roller Mixing Mill
Principle: The material rolls with the grinding media (such as
steel balls, ceramic balls) in the rotating drum, and is mixed and
ground through impact, rolling and friction. The drum can be placed
horizontally or tilted, and the speed determines the grinding
intensity.
Features: Suitable for fine crushing and uniform mixing of brittle
materials. The grinding effect is related to the ball-to-material
ratio, ball diameter distribution and drum speed.
Applications: ore sample preparation, ceramic raw material
crushing, battery electrode material mixing, etc.
3. Planetary Ball Mill
Principle: Multiple grinding jars revolve around the central axis
while rotating themselves, generating strong centrifugal force and
impact force, causing the grinding media to collide and shear with
the material at high speed.
Features: The mixing and grinding efficiency is extremely high, and
nano-level particle size refinement can be achieved. It is suitable
for hard and brittle materials or high hardness materials (such as
metals and ores).
Applications: Nanopowder synthesis, catalyst preparation,
geological sample analysis, etc.
4. Double Cone/V-Type Mixer
Principle: The rotation of the container causes the material to
repeatedly flip and spread under the action of gravity, achieving
shear-free mixing, which is suitable for powdery or granular
materials.
Features: The mixing process is gentle and does not easily destroy
the particle structure of the material. It is suitable for samples
that are sensitive to particle size (such as drug powders).
Application: formula mixing in the pharmaceutical industry,
preparation of food additives, etc.
5. Three Roll Mill
Principle: Three parallel rollers rotate towards each other at
different speeds. When the material passes through the gap between
the rollers, it is squeezed and sheared to be refined and mixed.
Features: It can accurately control the thickness and fineness of
materials, and is suitable for high-viscosity slurries (such as
inks, slurry coatings).
Applications: preparation of printing inks, production of
electronic pastes (such as silver paste), etc.
