Ribbon Blender VS V-cone Mixer

Ribbon Blender VS V-cone Mixer

V mixer

Ribbon Blender VS V-cone Mixer：

There are many effective mixing machines for blending ingredients, but Ribbon blenders and V-cone mixers are both commonly used in industrial processes to mix and blend different substances. They all can be used in the food industry, chemical industry, pharmaceuticals, plastic industry, etc. They are both designed to achieve the same purpose- a thorough blending of materials. While they both can be used for a variety of materials, there are several key differences between the two that make them suitable for particular applications. In this article, we will discuss the differences between the two, and how to decide which is best for your individual needs.

V-cone mixer working principle：

The V-cone mixer is a type of industrial mixing equipment that uses a v cone-shaped mixing chamber and two impellers to create a 360-flip mixing action. Its basic configuration is the motor, the electric panel, the barrel, the feeding port, and the discharge port. it rotates in 360 opposite directions, creating a strong vortex that draws material from the sides of the cone and down to the bottom, where it is then drawn back up to the top of the cone. This creates a powerful mixing action that ensures a thorough blend of materials. The v mixer rotates at a pre-set constant RPM to mix the homogenized materials in a short time to get a uniform mixture. Sometimes a force agitator is recommended for the bad fluidity materials.

Ribbon mixer working principle：

The ribbon blender is a type of mixer that uses a helical ribbon agitator to mix and blend dry powders and granules. It consists of the base, the motor, the electric panel, the discharge port, a drive system, and a horizontal U-shaped trough with a double helical ribbon or blade running along the length of the trough to do the rotation action in opposite directions. The ribbon rotates at a slow speed, which helps to mix various ingredients thoroughly and evenly. And the RPM of the ribbon mixer is adjustable according to the different machine types, with big capacity, the slower speed to keep stable and more effective in the mixing process. The ribbon blender is most effective when used to mix various natural ingredients, such as powders, granules, pellets, 10-20% liquid, etc.

Advantages of Ribbon Mixers and V-Mixers：

To make the material mixing effect more uniform and effective, no matter what kind of mixing equipment needs to be empty enough space to make the mixing process more smooth and to ensure the materials are mixed properly. Of course, the filling volume for the mixer is also based on the specific material natural such as the density, the specific application, etc. The difference in the optimal filling volume for the ribbon blender and the v-cone mixer is obvious.

According to our rich experience in mixing machines, the optimal filling volume for a ribbon blender is around 50%-80%, but the v-cone mixer is around 40-50%. The difference is caused by the machine shape, the mixing principle, the applicable materials, etc to lead to the same mixing target, v-mixing requires the use of larger models to achieve the target capacity. So the budget will be different.

There are four ways for the ribbon blender cover, but the v-cone mixer adopts the round opening at the top of the cylinder. It can also be seen from this point, the spiral mixer is more suitable for mixing large quantities, V mixer is suitable for more refined mixing. But they are all suitable for the screw conveying method to uploading the powder, it is easier and faster than the manual uploading way.

For the ribbon blender, we recommend two options normally: 1. pneumatic valve 2. manual butterfly valve. And the height between the discharge port and the floor is adjustable. It depends on the different reception methods, if you use a bag or box to package directly, the normal height of 50-60cm is a suitable range, but if you want to connect a hopper to convey to the next handling production line, the height can be customized to 90-1000cm.

For the v-cone mixer, it adopts the sanctity manual butterfly valve mostly. With the one-touch return function, it is possible to keep the discharge opening at the bottom at all times, which is convenient for receiving materials. However, if you need to connect the transfer system, you need to connect it manually after the mixing is finished.

Whatever discharge way to adopt, the horizontal ribbon blender always leaves residue on the barrel’s bottom. The vertical v-cone mixer can complete 100% discharging

Overall, the ribbon blender and the v mixer are two different tools designed to achieve the same purpose. Both are effective at mixing a range of materials, but the ribbon blender is best suited for large capacity and various material mixing processes, and the v mixer is ideal for mixing with small differences in material properties and good flowability.

Why is the trommel sieve clogged?

Why is the trommel sieve clogged?

Cause Analysis

When the trommel screen works for a long time, its screen may be clogged. The operation mode of the drum screen is to install the drum device on the frame obliquely, and the motor is connected with the drum device through the reducer through the coupling, and the drum device is driven to rotate around its axis. According to the analysis by Chenwei technicians, the main reasons for the clogging of the screen holes are as follows:

  • Contains a large number of particles close to the separation point;
  • The moisture content of the material is high;
  • Spherical particles or materials with multiple contact points to the sieve holes;
  • Static electricity occurs;
  • The material is fibrous;
  • There are many flaky particles;
  • The wire diameter of the woven screen is too thick;
  • For thicker screens such as rubber screens, the hole shape design is unreasonable, and the upper part is not small and the lower part is large, so that the particles are stuck.
  • Screening materials with very fine particles or high moisture content.

The solution to the clogging of the trommel screen:

  • A device can be added to the fixed frame of the drum screening machine, and then the device rotates to drive the belt mounted on it to continuously beat the surface of the screen hole, so as to pump out the raw material particles blocked in the screen hole.
  • A bumper can be used for impact, which requires a sufficiently large wall thickness of the supporting ring bushing to withstand the impact of the bumper when removing clogged raw material particles.
  • Use the method of water flushing to wash away the impurities that block the screen. A stainless steel steel pipe with many small holes can be installed on the top of the drum screen, and the impurity that blocks the screen can be washed away by the momentum of the water flow.
  • When the particle size of the material is fine, the mud content is large, and the screening particle size is small, the moisture will play a decisive role in the blockage of the screen. When the moisture in the material is greater than 5%, if there is no condition to dry the material, the sieve surface and sieve holes should be selected in a targeted manner. When the moisture is greater than 8%, wet sieving should be used.
  • For materials with more flaky particles, it is necessary to change the material crushing method and the particle size matching of different crushing methods.
  • Reasonably adjusting the tension of the screen is an effective method to reduce the hole blocking of the screen. Reasonable tension makes the screen and the supporting beam produce slight secondary vibration, which effectively reduces the occurrence of hole blocking. The specific method is to make the tensioning hook into a constant force tensioning mechanism, that is, to install a spring on the tensioning bolt.
  • The screen frame of the screen machine is equipped with a small hammer, which continuously hits the screen frame, and the materials blocked on the screen will fall off automatically with the impact of the small hammer. Or add an external cleaning device to clean up the sundries attached to the screen.

What is electric vacuum conveyor?

Electric vacuum conveyor, also known as vacuum conveyor, is a dust-free closed pipeline conveying equipment that transmits particles and powder materials by means of vacuum suction.

It uses the pressure difference between vacuum and environmental space to form airflow in the pipeline and drive the movement of powder materials, so as to complete the conveying of powder.

Mainly used for conveying powder and granular materials, such as raw material medicine powder, chemical powder, metal oxide powder, powder, etc; capsules, tablets, pills, small food particles, etc. It is not suitable for conveying materials that are too wet, too viscous, and too heavy. Using a single air as a power source, it belongs to intrinsically safe explosion-proof equipment, which can be used for conveying flammable and explosive materials on occasions with high explosion-proof requirements. At the same time, because only the use of stainless steel, PVC or PU pipe, and soft connection, the installation, repair, and maintenance are quite convenient.

How to use Ribbon Mixer?

How to use Ribbon Mixer?

Select Ribbon Mixer based on daily production. Because each batch of materials per batch of materials is about 10 minutes, and the time for materials and feed, each batch of materials can be calculated in 15 minutes, and 4 batches of materials can be processed continuously in 1 hour. If you choose a mixer of 100 kg per batch, 400 kg can be processed per hour. Users can choose a horizontal Ribbon Mixer according to their needs.

According to the working principle of the horizontal Ribbon Mixer, the ability to push the material in the opposite direction should be basically the same. Because the spiral band of the internal spiral band should be less than the external spiral band, in order to achieve the consistency of the push material, the spiral band spiral distance should be less than the external spiral belt, and the width should be greater than the external spiral belt, otherwise the material will concentrate in one direction. Therefore, pay attention to this when choosing a horizontal hybrid.

Due to the different friction coefficients of shattered particle size and material, the materials of various components can participate in the mixed time, resulting in the unevenness of the product. It has been realized and improved the product. One is to pay attention to the processing accuracy to reduce the bottom gap to about 3 mm

When choosing a horizontal Ribbon Mixer, you should pay attention to the method of raising. You should communicate with the supplier in time to choose a valve form that is suitable for your own craftsmanship, and do not choose the form of the side port. The reason is that when the mixer is mixed at the specified time, it can be cleared at once in a short time to ensure the uniformity of the material; if the spiral band of the side port is gradually cleaned, the first is to delay the time and reach the expected productivity. The material book has reached the best degree of uniformity. Excessive stirring will cause the material to distinguish the material and destroy the uniformity, thereby losing the significance of using a horizontal mixed machine.Use the horizontal Ribbon Mixer to pay attention to the order of the feeding. Generally, it is to cast large ingredients, such as corn flour, soybean meal powder, etc., and then submit the group to divide, such as premix. Note that premix must not use a spiral increase, apply disposable rollover feed, or use artificially feeding, so as to avoid the loss of the out -of -analysis of the effective ingredients in the premix.

Using a horizontal Ribbon Mixer, it should be applied in batches after the mixed machine is started. Do not stop when the mixing is erected, and then mix a batch after the net is out. If it starts after full load, the motor will be burned too much after full load.
