High-Speed Double-Shaft Mixer

DSM Series

Features: High-Efficiency Mixing; Uniform Mixing; Energy-Efficient, Low-Maintenance; Convenient Operation with Expandable Features; Applicable to Powders with Varied Densities Across Industries.

Introduction

Designed for efficient mixing, the Double-Shaft Mixer is a high-quality, professional mixer featuring two parallel shafts with cross-shaped paddles rotating in opposite directions. This durable mixer generates centrifugal force, lifting materials to the top of the chamber, where they experience a brief "zero-gravity" effect before falling back down. This ensures thorough recirculation and uniform blending, making it an effective mixer for foodstuff, chemical, and biotech applications. The synchronized paddles shear and separate materials effectively, preventing clumping.

Mixer Benefit

- Provides a quick, consistent, and efficient mixing solution with minimal effort.
- Reduces mixing time (approximately 30 seconds to 5 minutes).
- Easy to maintain and clean.
- Quick discharge.

Operation Principle

Two parallel paddles:
The machine has two paddle shafts that are placed side by side and spin in opposite directions.
Cross-shaped paddles on each shaft:
Each shaft has paddles shaped like a cross
Synchronized operation:
The two shafts work together at the same time, with their paddles moving in patterns that cross each other but don't touch.
Centrifugal force: As the paddles spin, they create a force that throws the materials to the top of the chamber.
Also called zero-gravity mixer： When the materials reach the top of the curve, they experience a moment where they seem to float before falling back down.
Recirculating and mixing: The paddles keep the materials moving in a loop, mixing them repeatedly inside the chamber.
Shearing and separating: As the two shafts work together, they cut through and separate the materials, helping them mix quickly and evenly.
