square cone mixer

What is a square cone mixer?

The square cone mixer is a material mixing equipment commonly used in the pharmaceutical, food, chemical and other industries, suitable for uniform mixing of powders and granular materials. The equipment consists of a square cone container, which repeatedly rolls, diffuses and convects the material in the container through rotation, thereby achieving efficient mixing. 

The typical volume is between 100L and 2000L, which is suitable for different batch production needs. The material usually needs to be sieved before mixing, and the sieve mesh is generally 60 to 120 mesh to ensure the uniformity of the mixing effect. The square cone mixer has a simple structure, complete material discharge, and a mixing uniformity of more than 95%. It is suitable for process occasions with high requirements for material mixing accuracy.

Working principle of square cone mixer

Square cone mixer usually achieves material mixing in the following ways:

①Container rotation: The square cone container rotates around an axis, so that the material in the container is constantly flipped and mixed under the action of gravity.

②Baffle function: Some square cone mixers are equipped with fixed baffles inside the container. When the container rotates, the material will be blocked and impacted by the baffle, thereby enhancing the mixing effect.

③Spiral stirring: Some designs use cantilevered spiral stirrers to rotate in the conical container, lifting the material from the bottom to the top, and then falling by gravity to form a circular flow to achieve mixing.

Structural composition of square cone mixer

The basic structure of the square cone mixer mainly includes:

Square cone mixing cylinder: It is the main container for mixing. It is generally made of stainless steel and the inner wall is polished to prevent material adhesion.

Transmission system: It is usually composed of a motor, a reducer and a sprocket/belt, which is used to drive the mixing cylinder to rotate.

Bracket and rotating mechanism: Support the entire mixing cylinder and provide rotational power.

Discharging device: After mixing is completed, the cylinder rotates to the bottom of the discharge port at a certain angle and discharges the material through the valve.

Control system: It is used to set functions such as mixing time, speed, automatic shutdown, etc. Some models can realize PLC control.

Features of square cone mixer

When the charging ratio is 0.8, the mixing uniformity is as high as 99% or more, and the charging rate can reach between 50% and 80%.

The inner wall of the hopper is smooth and easy to clean, without dead corners. The mixer mixes in a fully enclosed state, forming a dust-free production environment without cross contamination.

The square cone structure and rotational motion of the square cone mixer can effectively make the materials of different components fully contact and mix.

The bottom of the cone is conducive to the smooth discharge of the material after mixing, with less residue. The feed valve is equipped with an anti-misoperation device for easy disassembly and cleaning.

The working parameters such as mixing time and speed can be set, frequency conversion speed regulation, smooth start and stop, and no vibration. It can be customized according to different production needs, such as adding vacuum feeding, liquid spraying and other functions.
