high speed planetary mixer, also known as vertical shaft planetary mixer, planetary mixer or vertical mixer, is a main form of forced mixer. Other forms include vertical shaft snail propeller type, single horizontal shaft type and double horizontal shaft type. Its core feature is that the stirring device adopts the principle of planetary motion: the stirring blades installed on the planetary carrier not only rotate around their own axis, but also revolve around the central axis of the stirring drum with the planetary carrier, forming a composite motion. This design ensures strong mixing effect, no dead corners, high mixing efficiency, and is suitable for uniform mixing of various materials such as concrete, refractory castable, UHPC, etc. Depending on the capacity, the number of planetary rotation axes can be one, two, or three [11]. Its transmission structure usually includes a planetary gear system consisting of a sun gear, planetary gears, and a ring gear
The high speed planetary mixer has the characteristics of uniform mixing and no dead corners, and is widely used in multiple industries that require high mixing uniformity.
This equipment is a powerful helper for the production and manufacturing of prestressed concrete and precast concrete. It is commonly used to produce high-quality concrete (such as dry hard, semi dry hard, and plastic concrete), high-grade concrete, fiber reinforced concrete, as well as precast components such as cement pipes, utility poles, prefabricated components, block bricks, pipe piles, and subway segments.
The refractory planetary mixer is a representative of high-quality castable mixing machinery, which can meet the demand of the castable industry for high uniformity mixing.
This device is also suitable for the ceramic industry, glass, and casting industry. For example, planetary mixers (vacuum type) can be used to heat and stir ceramic slurry under vacuum, achieving sufficient mixing of ceramic refractory powder with paraffin matrix of different particle sizes.
The specialized equipment derived from the vertical axis planetary mixer technology is suitable for the production of UHPC ultra-high performance concrete, ensuring uniform fiber distribution and avoiding agglomeration.
Vertical planetary mixer are often used as industry-specific laboratory mixers due to their high uniformity and customizable characteristics, suitable for experimental scenarios with extremely high requirements for material mixing uniformity.
