Many users choose the original domestic vertical cone mixing equipment for powder and powder mixing equipment, but experts suggest that because the vertical cone mixer has many shortcomings and a high maintenance rate, the powder / powder When mixing bulk or granular materials, a horizontal mixer should be selected. The equipment has high mixing efficiency, good mixing quality, short discharge time, and little residual amount. However, the selection and use of horizontal mixers should pay attention to the following points:

1. Select the horizontal mixer according to the daily production volume. Because the processing time of each batch of materials in the mixer is about 10 minutes, plus the time of discharging and feeding, the processing time of each batch of materials can be calculated as 15 minutes, then 4 batches of materials can be processed continuously in 1 hour. If you choose a mixer with a processing capacity of 100 kg per batch, you can process 400 kg per hour. Users can choose the horizontal mixer according to their needs.

2. According to the working principle of the horizontal spiral belt mixer, the ability of the double spiral belt used for stirring and mixing to push materials in the opposite direction should be basically the same. Since the pitch of the inner spiral belt should be smaller than that of the outer spiral belt, in order to achieve the same ability to push materials, the pitch of the inner spiral belt should be smaller than the outer spiral belt, and the width should be larger than the outer spiral belt, otherwise the material will be concentrated in one direction. Therefore, pay attention to this when choosing a horizontal mixer.

3. According to the design principle, the gap between the spiral belt and the shell in the spiral belt mixer can be 4 mm to 10 mm, and the materials can be driven to participate in the mixing by friction. However, due to the different crushing particle size and the friction coefficient of the materials, the mixing time of the materials of various components will be different, resulting in non-uniformity of the product. At present, some manufacturers have realized this and made improvements to their products. One is to pay attention to the machining accuracy, so that the bottom gap is reduced to about 3 mm; the other is to make the position between the main shaft and the housing into an adjustable form, according to the amount of wear can often adjust the gap between the spiral belt and the housing . When choosing a mixer, these two forms of products should be the best choice.

4. Pay attention to the discharging method when selecting the horizontal spiral belt mixer. Communicate with the supplier in a timely manner to choose the valve form suitable for your process, and at the same time do not choose the discharge form of the side port. The reason is: when the mixer finishes mixing in the specified time, it can be cleaned once in the shortest time to ensure the uniformity of the material; if it is gradually cleared with the side mouth spiral belt, one will delay the time and the expected productivity will not be achieved, the second The material has already reached the best uniformity. Excessive stirring will cause the material to segregate and destroy the uniformity, thus losing the meaning of selecting a horizontal mixer.

5. Pay attention to the feeding sequence when using the horizontal mixer. Generally, large materials such as corn meal and soybean meal are added first, followed by small components such as premix. Note that the premix must not be fed by a screw elevator, and a one-time dumping feed should be used, or manual feeding, so as to avoid the segregation and loss of active ingredients in the premix.

6. When using a horizontal mixer, batch feeding should be done after the mixer is started. Don't stop the machine at the end of the mixing and unload. Mix a batch after the net material is discharged. If it is restarted after full load, it will cause too much power and burn the motor.

Choosing a suitable horizontal mixer and using it properly will significantly improve the quality of the mixture and will soon reflect the benign effect in the production process. If you can further master the self-compounding technology, you can also greatly reduce the cost of materials, thereby increasing profits.
