The four types of vertical mixers you mentioned are all suitable for different materials in industrial production. Although they belong to the same vertical structure, there are significant differences in structural design, functional configuration, and adaptation scenarios. The following is a detailed analysis of each type of equipment:

　　PVC plastic vertical mixer

　　This type of equipment is mostly a high-speed forced mixing machine, specifically designed for mixing and coloring PVC resin powder and PVC particles. It can also be used for drying treatment before PVC molding and processing, and is one of the core auxiliary machines in plastic processing plants.

　　Core structure and principle: Equipped with high-speed rotating impellers, the barrel body is mostly made of 304 stainless steel material, and the inner wall is polished with anti sticking material. During operation, the impeller drives the animal material to make tangential motion through friction and thrust. At the same time, the material is thrown towards the barrel wall by centrifugal force and rises, then falls back to the center of the impeller due to gravity, forming a spiral upward and downward circulation motion. The material particles collide and break each other, achieving rapid and uniform mixing. During the process, the material temperature will naturally rise, and it can also assist in absorbing liquid additives.

　　Key features: divided into heating and drying type and non heating type. The heating type has an adjustable temperature range of 0-150 ℃ and can handle the drying needs of PVC moisture absorbing raw materials; Some models come with frequency conversion function, which can adapt to the speed requirements of different mixing stages. The mixing uniformity can reach over 98%, and it is easy to clean during color and material changes.

　　Common specifications: The motor power of small 100L models is about 22kW, while the motor power of large units such as 500-1000L can reach 75kW. There are also large capacity customized models ranging from 300kg to 15 tons, suitable for different needs from small-scale trial production to large-scale production.

　　Rubber granule vertical mixer

　　This device is suitable for mixing rubber particles, plastic particles, and various recycled materials, and is commonly used in industries such as cutting, plastic granulation, and recycling of recycled materials. It can solve the problem of differences in the properties and colors of rubber particles produced at different times.

　　Core structure and principle: The main body is a vertical barrel body, which can be made of stainless steel or iron plate material. The core is a spiral mixing structure that supports spiral feeding. Workers can feed materials on the ground or directly feed them into the barrel from the granulator through a fan. During operation, the propeller blades roll up and down with animal material. For rubber particles with higher hardness, some customized models will thicken the mixing blade to enhance durability.

　　Key features: Both heating and non heating types are available. The heating type can simultaneously dry and mix rubber particles, avoiding particle agglomeration; The equipment occupies a small area and has a large capacity. The bearings are installed in a built-in manner, which can avoid the problem of jamming caused by material contact with the bearings and extend their service life; It also has functions such as overload protection and timed operation.

　　Common specifications: For models as small as 100L, the motor power is 2.2kW and the speed is 350r/min; Large capacity models can reach up to 15 tons, with a bucket size of approximately 140 * 265cm for 1-ton models, a motor power of 4kW, and a speed of 460r/min.

　　Organic fertilizer vertical mixer

　　The mainstream is the vertical disc mixer, which is the key equipment for adjusting the carbon nitrogen ratio in the production of organic fertilizer. It is suitable for mixing straw powder, livestock manure, bacterial agent and other materials with large density and humidity differences, and can also be used for mixing feed, fertilizer and other raw materials.

　　Core structure and principle: The core is a tilted disc structure, lined with polypropylene or stainless steel plates for anti sticking and wear-resistant properties. It is equipped with a cycloidal pinwheel reducer, a scraper plate, a feeding device, and a grease adding pipeline. During operation, the rotating disc drives the animal material up along the edge circumference, and after reaching a certain height, it slides down along the center, forming a "rise slide" cycle. With the shear action of the scraper plate, the material is fully mixed.

　　Key features: The mixing uniformity is extremely high, reaching 92% -98%, which can accurately control the carbon nitrogen ratio of organic fertilizer and help shorten the fermentation cycle; Suitable for materials with a moisture content of 20% -70% and a fiber content of ≤ 40%, with a residual content of only 1% -3%; Low energy consumption, equipment with a processing capacity of 5 tons/hour has a power of only 7.5-15kW and occupies only 2-4 square meters. Installation does not require complex foundations.

　　Common specifications: Represented by models such as PJ1600, the production capacity can be adjusted from 2 tons/hour to 10 tons/hour, suitable for small and medium-sized organic fertilizer plants with a daily processing capacity of 10-50 tons, and also supports customized complete production lines.
