Horizontal mixers are distinguished according to the form of agitation. The mixing mechanism of the common screw type mixer is usually composed of double stud, and the rotation direction of the external stud and the internal screw is opposite, which ensures the small resistance movement of the mixed material in the barrel. The positive and negative rotating stud is installed on the same horizontal axis to form a low power and efficient mixing environment. The spiral blade is usually made of double or three layers. The outer spiral brings the material from both sides to the center. The inner spiral conveyed the material from the center to the two sides, which can make the material flow more swirl in the flow and accelerate the mixing. Speed, improve the mixing uniformity.
The selection of horizontal mixer is usually done in several ways.
1. according to the daily production selection
Because the processing time of each batch of material is about 10-30 minutes, and the time of feed and feed is added, the processing time of each batch can be 30 minutes, then 2 batches can be processed in 1 hours. Users can choose horizontal mixer according to their own needs.
2. According to the working principle of the horizontal mixer
The ability of the double screw rods to push materials in opposite directions for mixing and mixing is basically the same. Because the pitch of the inner and outer stud is basically the same, the ability to push the material is the same. Therefore, we should pay attention to this when choosing the horizontal mixer.
3. Select the material according to the characteristics of the material.
The clearance between the screw rod and the shell can be 4 millimeters to 10 millimeters, and the material can be driven by friction to participate in mixing. Because the particle size and the friction coefficient of the material are different, the mixing time of different components will be different, resulting in uneven mixing of the products. At the same time, due to different material density, the uniformity of mixing is also different. When choosing a mixer, it is necessary to choose the right diameter of the motor, reducer and mixing shaft according to the density of the material.
