Product Overview
The drum mixer (also known as a drum pre-mixer) is an efficient mixing machine for powders and granules. It is widely used in dry powder mixing processes across industries including pharmaceuticals, food, chemicals, feed, metallurgy, and electronics. Through the 360° rotation of the drum, the equipment causes materials to undergo multiple movements, such as translation, shearing, and diffusion, in an enclosed container, thereby achieving thorough and uniform mixing within a short time.
The drum mixer is particularly suitable for mixing applications requiring high uniformity and involving materials with significant differences in specific gravity. With its compact structure, easy operation, attractive appearance, small footprint, and excellent mixing performance, it has become an ideal choice for powder mixing processes in many industries.
Working Principle
The drum mixer consists of core components including a motor, cycloidal pinwheel reducer, base, mixing hoop, and mixing drum.
Its operating process is as follows: The motor is directly mounted on the shaft end cover of the cycloidal pinwheel reducer. The reducer output shaft transmits motion to the drive shaft on the base through a flexible coupling. The nylon guide wheels on the drive shaft use friction to drive the mixing hoop in a 360° rotational motion. The mixing drum rotates accordingly, causing the materials inside to undergo combined movements such as translation, shearing, and diffusion.
During rotation, the materials undergo forward rolling mixing, inclined mixing on both sides, and multidirectional, multi-angle mixing inside the drum. The upper and lower inclination angle of the drum can reach 40°. This multidirectional movement increases the number of cross-mixing points within the drum, significantly improving the mixing effect. The equipment can also operate in both forward and reverse directions, further enhancing mixing uniformity.
Structural Features
Drive system: Features a direct connection between the cycloidal pinwheel reducer and motor, offering high transmission efficiency and smooth operation.
Mixing drum: The drum is made of stainless steel, with finely polished inner and outer walls. It has no dead corners or material accumulation and complies with GMP standards. The drum can rotate 360° circumferentially and, together with a 40° upper and lower inclination angle, ensures all-round material mixing.
Guide mechanism: Nylon guide wheels are installed on the drive shaft and use friction to drive the mixing hoop to rotate, providing a simple and reliable structure.
Overall structure: Compact structure, small footprint, easy operation, and attractive appearance.
Closed mixing: Materials are mixed inside the enclosed mixing drum, preventing dust leakage and ensuring hygiene and safety.
Product Advantages
-
High mixing uniformity: Materials undergo multiple combined movements, including translation, shearing, and diffusion, inside the drum. With numerous cross-mixing points, the mixing effect is excellent.
-
High loading coefficient: The loading coefficient can reach 0.6, higher than the 0.4 of conventional mixers, enabling a large single-batch processing capacity.
-
High mixing efficiency: Typical mixing time is only 8–12 minutes, providing high efficiency in a short time.
-
No-dead-corner design: The inner wall of the drum is finely polished, with no dead corners or material accumulation, allowing easy discharge and cleaning.
-
Easy operation: Compact structure, easy operation, and small footprint.
-
Hygienic and safe: The drum is made of stainless steel, provides good sealing performance, and meets GMP standard requirements.
-
Wide range of applications: Suitable for the pharmaceutical, food, chemical, electronics, feed, metallurgy, ceramics, and other industries.
