How to choose a planetary centrifugal mixer（2）?

The importance of planetary mixers as key mixing equipment is self-evident in today's industrial production and various laboratory applications. The planetary centrifugal mixers on the market are mainly divided into two types: contact type and non-contact type.

The following are the differences in mixing capacity between contact planetary centrifugal mixers and non-contact planetary centrifugal mixers:

Contact type:

Mixing capacity: The capacity of common contact planetary centrifugal mixers is generally between 1 liter and 1000 liters. For example, a 50 liter planetary mixer can meet the needs of small-scale production or laboratory small-scale production. The large contact planetary centrifugal mixers used in industrial production can have a capacity of hundreds or even thousands of liters.

Medium to large capacity materials: In the mixing of materials with medium to large capacities, sufficient mixing can be achieved in a short period of time. Its unique planetary motion allows the mixing blade to cover a wide range without any mixing dead corners, ensuring the uniformity and consistency of material mixing. It is suitable for large-scale production where high mixing efficiency and effectiveness are required.

Adapt to various material characteristics: can handle materials of various viscosities and densities, with particularly significant mixing effects for high viscosity materials, effectively preventing material agglomeration during mixing, and can be widely used in multiple industries such as chemical, electronics, and building materials.

High equipment cost: The structure of the contact planetary centrifugal mixer is complex, and the equipment cost is relatively high. Due to the presence of components such as the planetary transmission mechanism, the maintenance cost is also higher than that of ordinary mixers. For some users with limited budgets, it may increase investment costs.

Not suitable for ultra small capacity materials: When dealing with ultra small capacity materials, the advantages of contact planetary centrifugal mixers are not obvious. Due to the relatively large size of their mixing blades and containers, it is difficult to achieve precise mixing for small amounts of materials and can easily cause material waste.

Non contact:

Mixing capacity: The capacity of non-contact centrifugal mixers is relatively small, and the maximum processing capacity of common single cup equipment is generally below 1000g/600mL. The total capacity of multi cup equipment is also relatively limited,

SMIDA's non-contact centrifugal mixers come in various specifications, including 300ml, 700ml, 1500ml, 2L, 4L, 9L, and 14L standard containers.

Protecting material characteristics: In small capacity material mixing, due to the use of non-contact mixing method, there will be no direct shear and extrusion effect on the material, and mixing can be achieved under mild conditions, maximizing the protection of the physical and chemical properties of the material. It is particularly suitable for mixing materials such as biological agents and polymer materials that are sensitive to shear forces.

Small and medium-sized materials: suitable for handling small and high-value materials, able to accurately control the mixing process to ensure uniform mixing of materials, and can be used in fields such as scientific research experiments and electronic material production that require high material quantity and mixing accuracy.

Insufficient large capacity processing capability: The capacity of non-contact centrifugal mixers is relatively small, which cannot meet the demand for one-time processing of large amounts of materials in large-scale production. Multiple batch mixing is required, reducing production efficiency.

High equipment strength requirements: Due to the need to drive the mixing components to rotate at high speeds, non-contact planetary centrifugal mixers require high materials and manufacturing processes to ensure stability and reliability at high speeds, which also leads to an increase in equipment costs.
