The difference between granulation dry mixing and wet mixing

In the chemical industry, the processing of granular materials is a complex and critical process, in which "granulation dry mixing" and "wet mixing process" are two common particle processing methods. This paper will analyze the differences, advantages and disadvantages of these two processes in depth, and explore their application scenarios in actual production, so as to help chemical practitioners better understand and reasonably select the processing methods suitable for the process.

1. Definition and characteristics of granulation dry mixing process

the granulation dry mixing process is a process method widely used in the processing of granular materials, the core of which is to dry mix the granulated particles with other components (such as additives, fillers, etc.). This process has the following characteristics:

• drying and granulation separation: The granulation dry mixing process first completes the granulation of the particles to ensure the uniformity and shape of the particles, and then performs drying treatment to prevent the particles from affecting the mixing effect due to humidity during the mixing process.
• Efficient mixing: Mixing under dry conditions can effectively avoid friction between particles and improve mixing efficiency and uniformity.
• wide applicability: Suitable for scenarios that require high-precision mixing, such as medicine, food, pesticide and other industries, to ensure uniform distribution of ingredients.

The advantages of granulation dry mixing process:

• suitable for scenarios that require high-precision mixing.
• Helps improve mixing efficiency and uniformity.
• Suitable for products with strict requirements on particle shape and size.

Disadvantages of granulation dry mixing process:

• high requirements for equipment, the need for professional equipment and control systems.
• The operation is complex and the initial investment is large.

2. Definition and characteristics of wet mixing process

the wet mixing process is a process in which particles are mixed with other components in a wet state during the processing of the particulate material. This process has the following characteristics:

• wet mix: The wet mixing process mixes the particles before they are dry, which can reduce the friction between the particles and improve the mixing uniformity.
• Wide scope of application: Suitable for scenes that require uniform mixing but have certain requirements for humidity, such as chemical raw material processing, powder mixing and other fields.
• Low equipment requirements compared with the dry mixing process, the equipment requirements of the wet mixing process are relatively low and the operation is simpler.

Advantages of wet mixing process:

• suitable for scenes that require uniform mixing but have certain requirements for humidity.
• Simple operation and low equipment requirements.
• Applicable to enterprises with limited investment in equipment.

Disadvantages of wet mixing process:

• the mixing efficiency is relatively low, especially for high-precision mixing scenarios.
• It is susceptible to changes in humidity and temperature.

3. Application analysis of granulation dry mixing and wet mixing process

• pharmaceutical Industry: In the processing of pharmaceutical raw materials, the wet mixing process is often used to improve the uniform distribution of active ingredients, while the granulation dry mixing process is suitable for products with strict requirements on particle shape and size.
• chemical raw material processing: The granulation dry mixing process is often used to produce high-precision chemical raw materials, while the wet mixing process is suitable for enterprises with limited investment in equipment.
• food industry: The wet mixing process is often used to produce uniform food additive mixtures, while the granulation dry mixing process is suitable for food products that require extremely high mixing uniformity.

4. Problem analysis: Which process is more suitable for your production needs?

The following issues need to be considered when selecting a dry or wet blending process for granulation:

• production target: Is it the pursuit of high-precision mixing, or is there a certain requirement for mixing uniformity?
• Equipment conditions: Does the company have advanced equipment and control systems?
• Cost Requirements: Are equipment investment and operating costs within budget?
• Process complexity: Does the company have a professional team and experience to operate complex processes?

Through the above analysis, it can be clearly seen that the granulation dry mixing and wet mixing processes have their own applicable scenarios and advantages and disadvantages. Choosing the right process can not only improve production efficiency, but also reduce production costs to meet the actual needs of enterprises.

5. Summary: How to choose granulation dry mixing and wet mixing process?

In chemical production, granulation dry mixing and wet mixing processes are two important particle processing methods, and each process has its own unique advantages and application scenarios. The key to choose which process depends on the specific production needs and enterprise conditions. The granulation dry mixing process is suitable for scenarios that require high-precision mixing, while the wet mixing process is suitable for enterprises with limited equipment investment and low process requirements. Through in-depth analysis of production objectives, equipment conditions and cost requirements, chemical practitioners can better choose the right process, improve production efficiency and improve product quality.
