Talking About The Problem Of Material Wall And Excessive Loading Of Double Cone Mixer

Whether it is stainless steel or not, the Double Cone Mixing Machine has encountered the situation that the mixed materials will not stick out on the inner wall. This is not only the reason that the inner wall is not smooth enough, but also the material properties are different but not targeted. Factors such as temperature, feed volume, speed, etc., so whenever this happens, we need to investigate the cause of it in order to avoid and reduce the occurrence of such problems. In addition, there is a common Failure is a headache for everyone. It is very easy to accidentally install too much in the process of installing materials. So how can this situation be resolved? The following Double Cone Blender suppliers will take everyone to take a look.

How to alleviate the problem of material wall formation of double cone mixer?

1, lumen wall coating

According to the specific properties of the material, a specific anti-caking wall protective layer is coated on the double cone rotary vacuum mixer to prevent the material from forming a wall. However, this requires higher coatings. On the one hand, it must consider the physical properties of the coating; on the other hand, it must consider whether it will cause cross-contamination.

2, to improve the smoothness of the cavity wall

Before each batch of materials is mixed, improving the smoothness of the cavity wall can effectively reduce the degree of material wall formation, but before mixing, regularly cleaning the cavity wall of the mixer, which also greatly increases the workload of the workers in the drying room.

3.Optimization of step control such as feeding, temperature rise, speed, etc.

According to the nature of the material, prior to mixing, optimizing the steps of feeding, temperature rise, and speed of the mixer can also effectively reduce the degree of material wall formation. However, for special materials, the optimization of the feeding, temperature rise, speed and other steps of the mixer requires related orthogonal optimization tests to obtain the optimal mixing conditions. Under normal circumstances, variable temperature mixing is usually better, that is, the temperature is low at the beginning of the mixing, and the temperature is gradually increased to increase the mixing speed.

4, dry mix back

Before each batch of wet product is mixed, add a certain amount of dry product from the previous batch. Using the method of mixing can effectively eliminate the wall of the material and possibly improve the mixing efficiency of the material.

5.Improve the crystallization effect of the material pre-process

This method is mainly to change the crystal structure of the material from the process, and to change the crystallization or desolvation process of the material, which can fundamentally eliminate the wall of the material. Risks, and fundamentally change the process, it is more difficult.

6.Add the media ball to the mixture

In the process of mixing materials, adding inert media balls to mix with the materials can effectively reduce the material wall. However, in the process of selecting the media balls, it is necessary to fully consider the effect of the shape of the media balls on the inner liner of the mixer, and more importantly Separation and recovery process with materials in the later stage.

What to do if the double cone mixer has too much loading?

Because the loading volume of the double cone mixer is related to the bulk density of the material (referring to the mass of the material per unit volume), in general, the material specific gravity of the double cone mixer is calculated at 0.6 g / cm3. If it exceeds this specific gravity, On the one hand, it will affect the drying efficiency of the material; on the other hand, if it is operated for a long time, it will reduce the service life of the motor, the turbine reducer, and the sprocket, chain, and bearing. Under normal circumstances, the filling rate of the double cone mixer (the ratio of the actual filling volume to the volume of the drying cylinder) is usually between 30% and 50%, and the vacuum cover in the double cone mixer cannot be covered, otherwise it will affect drying rate.

The above is the method shared by the suppliers of Ribbon Mixer Machine on how to minimize or avoid the phenomenon of double-cone mixer material wall formation, as well as the analysis of the problem of excessive loading, I hope it will be helpful to you.
