Our Introduction
The twin - shaft laboratory mixer is an experimental equipment commonly used in fields such as materials science, construction, and chemical engineering. It is mainly used for mixing various powders, slurries, or viscous materials. Its core feature is the adoption of two parallel horizontal (placed horizontally) mixing shafts, which achieve efficient and uniform mixing through rotation in opposite directions.
Structure and Composition
Mixing Shafts
There are two horizontally parallel mixing shafts, usually equipped with spiral blades or paddles. They rotate in opposite directions (one clockwise and the other counter - clockwise), generating strong shear and convective mixing.
Mixing Tank
Generally, it is a U - shaped or circular tank. The material can be selected as stainless steel, wear - resistant steel, or plastic (chosen according to the corrosiveness of the materials).
Drive System
Composed of a motor and a speed reducer, it controls the mixing speed and torque. Some devices support variable - frequency speed regulation.
Discharging Device
There is a manual or electric discharge door. Some models are equipped with pneumatic discharge to improve efficiency.
Control System
It can be a simple button control or a PLC touch - screen, where parameters such as time and rotation speed can be set.
Working Principle
When the two shafts rotate, the materials move axially and radially simultaneously:
Axial Movement
The spiral blades push the materials to move back and forth along the axis.
Radial Movement
The paddles throw the materials from the center to both sides, forming cross - mixing.
Shearing Action
A high - intensity shearing force is generated in the area between the two shafts, which is suitable for dispersing agglomerated particles or high - viscosity materials.
Core Features
Efficient Mixing
The twin - shaft design enables more uniform mixing compared to single - shaft mixing, especially for high - viscosity or easily agglomerated materials.
Flexible Adaptability
The blades can be replaced or the rotation speed can be adjusted to adapt to different materials (such as concrete, coatings, ceramic slurries, etc.).
Small - batch Processing
The capacity of laboratory models is usually 1 - 50 liters, which is suitable for research and development or small - scale experiments.
Controllable Data
It can record parameters such as mixing time and power consumption, which is convenient for experimental analysis.
Typical Application Fields
Building Materials
For experiments on the mix proportion of cement mortar and concrete.
Chemical Industry
For testing the uniformity of pigments, coatings, and inks.
