What are the discharging methods of mixer

Mixer is an important and indispensable equipment in modern industrial production, its role is to mix different materials to meet the diverse production needs. In the use of mixing machine, the choice of discharging method is particularly critical, it directly affects the production efficiency, material quality and ease of operation. According to different material characteristics and production needs, the mixer can be roughly divided into the following discharging methods, each of which has its own unique advantages and scope of application.

A common way of discharging is gravity type discharging, which uses the material's own gravity from the bottom of the mixer discharging port natural outflow. This method is usually applied to powder or granular materials with good fluidity, fast discharging speed and relatively simple equipment structure, so it is widely used in mass production scenarios. However, gravity discharge also has certain limitations, such as viscous materials may be blocked, and easy to cause part of the material left in the equipment, increasing the difficulty of cleaning.

Another common way is the screw discharge, through the rotary movement of the screw conveyor to push out the material. This method is not only suitable for powder and granular materials, but also can be very good to deal with some poor fluidity or slightly adherent materials. Screw discharging allows for quantitative discharging and is particularly suitable for production lines with high requirements for refinement. However, due to the mechanical movement of the screw conveyor, it may cause damage to some fragile materials, in addition, its structure is relatively complex and costly.

For some light powders or materials that are easy to adhere, pneumatic discharge is a very effective option. This method uses the propulsion of compressed air to blow the material out of the mixer and transport it through the pipeline to the next process. The advantages of pneumatic discharging are high speed and low material residue, especially in large-scale continuous production. At the same time, however, this method requires a high degree of sealing of the equipment, the use of dust removal systems to avoid dust contamination, and relatively high energy consumption during operation.

In the laboratory or in small mixing plants, the tilting discharge is a simple and easy way. By tilting or turning the entire mixer body, the material is poured directly out of the mixer. This method is suitable for scenarios where the material needs to be switched quickly, and not only is the discharge clean and thorough, but cleaning is also very easy. However, due to the limitation of equipment size and weight, the tilting type discharging is usually only used for small-scale production, and in the process of dumping may generate dust, which needs to take certain protective measures.

In addition, scraper discharge is ideal for certain viscous materials or mixtures that tend to agglomerate. In this way, the material is pushed out by the mechanical scraper, ensuring that even highly viscous materials can be discharged smoothly from the plant. Scraper discharge is suitable for specific material types and is effective in minimising residue, but discharge speeds can be a little slower, while the complexity of the equipment and maintenance costs can be relatively high.

Comprehensively speaking, there are many kinds of mixer discharging methods, each of which has its own unique advantages and applicable scenarios. Choosing the right discharging method can not only improve production efficiency, but also reduce equipment maintenance costs and operating difficulties. In practice, many manufacturers will be based on the characteristics of the material, process requirements and production scale of different, customized discharge method or combined with a variety of technologies for optimization, in order to achieve maximum production efficiency.
