SMG Series Wet Mixing Granulator

Ⅰ. Overview and classification of SMG series wet mixing granulator

Wet mixing granulator is widely used in pharmaceutical, chemical, food and environmental protection industries, particle molding equipment, mainly used for powder raw materials by adding an appropriate amount of liquid adhesive (such as water, alcohol, etc.) for wetting, mixing, granulation, the formation of a certain strength, uniformity and fluidity of granular products.

According to the different structure and working principle, wet mixing granulator can be roughly divided into mixing granulator, extrusion granulator, spray drying granulator and other categories.Among them, the mixing granulator is the most common because of its simple operation and strong adaptability.

Ⅱ. SMG series wet mixing granulator working principle

The working principle of the wet mixing granulator is mainly based on the wetting and agglomeration of powder materials.

Inside the equipment, after the powder raw materials and adhesives are added in a certain proportion, the powder particles are uniformly wetted and gradually gathered to form larger particles through the rotation and cutting of the agitator.

With the continuous agitation, the particles are further combined tightly, and the wet particles that meet the requirements are finally formed.

In the whole process, the control of parameters such as stirring speed, adhesive dosage and mixing time has a crucial influence on particle quality.

Ⅲ. SMG series wet mixing granulator main components

Wet mixing granulator is mainly composed of the following key components:

3.1 Mixing system: including mixing shaft, mixing paddle, etc., to fully mix powder with adhesive and promote particle formation.

3.2 Mixing container: Stainless steel, corrosion resistant and easy to clean, used to hold materials for mixing granulation.

3.3 Adhesive feeding system: Used to precisely control the amount of adhesive added to ensure uniform adhesive distribution during pelleting.

3.4 Cutting system: Used in the pelletizing process to cut too long or too large particles to ensure the uniformity of particle size.

3.5 Discharge device: such as scraper, vibrating screen, etc., used to discharge the wet particles from the container.

Ⅳ. SMG series wet mixing granulation process

The basic process of wet granulation includes: preparation of raw materials → adding and mixing of adhesives → stirring granulation → cutting of pellets (if necessary) → drying of pellets (next step) → screening and packaging.

In the entire process, controlling the process parameters of each step, such as mixing time, mixing speed, binder ratio, etc., is essential to obtain high-quality particles.

Ⅴ. SMG series wet mixing granulator control system and operation

The wet mixing granulator manufactured by Jiangsu Bohong Company is usually equipped with an advanced PLC control system, which can realize automatic operation and remote monitoring.

The control system can precisely control key parameters such as mixing speed and adhesive supply, and adjust flexibly according to process requirements

At the same time, the system also has fault alarm and emergency shutdown functions to ensure the safe operation of the equipment.

The operation interface is friendly, which is easy for the operator to quickly get started and accurately execute the process instructions.

Ⅵ. SMG series wet mixing granulator performance indicators and parameters

The performance index of wet mixing granulator mainly includes particle forming rate, particle uniformity, equipment production capacity, energy consumption and so on.

Specific parameters vary according to equipment model and configuration, such as mixing power, mixing container volume, maximum particle diameter, etc.

In the selection of wet mixing granulator, these performance indicators and parameters should be comprehensively considered according to production requirements and product characteristics.

Ⅶ. SMG series wet mixing granulator maintenance and maintenance points

In order to ensure the long-term stable operation and extend the service life of the wet mixing granulator, regular maintenance and maintenance are required.

The main maintenance points include:

7.1 Clean the mixing container and mixing system regularly to prevent material residue and corrosio

7.2 Check and replace worn impeller blades, bearings and other parts.

7.3 Check the working status of the adhesive supply system and control system to ensure normal operation.

7.4 Check the lubrication of motor, reducer and other transmission parts regularly, and add lubricating oil in time.
