High Shear Mixer

The Hywell machinery High-shear mixer, also called High-speed mixer, Wet mixer, or Rapid Mixer, is an efficient and versatile blending machine for mixing of dry powders with the addition of liquid binder, within a very short time and with excellent cleaning abilities. It is able to give perfect results for mixing due to the innovative design of a central impeller-type mixer with a side vertical chopper. the wet high-shear mixers are widely used in pharmaceutical, chemical, foodstuff, and electronic industries.

High Shear Mixer Introduction

GHL Series high shear mixer(Super Mixing machine)is equipped with a closed container with blending tools driven from below.

Originally, the liquid was poured into the dry powder. Today, an improved dosed distribution using a spray nozzle is preferred in order to obtain a more even blending.

the GHJ series high shear mixers often connect with the YK series oscillating granulator to get 0.5-5mm wet granules, and then directly send the wet granules into the drying machine to get dried granules (instant granules), the drying machine can use Vertical Fluid Bed Dryer or Horizontal Fluid Bed Dryer, but it decides by the treating capacity. The final step of the processing system is the granules sifter. The granules sifter will separate the large powder particles from the powder, size is determined for the separation. The off size is bagged off and the powder can be either directly packed into big bags or conveyed to a silo system for other packing systems. but if it needs to get ball shape granules, it just needs to add one set of QZL series Spheronizer. if the ball shape granules want to coat. it just needs to add one set of fluid bed coating machines. any detail of this kinds line, please contact Hywell Machinery company!

High Shear Mixers Description

Hywell Machinery vertical high shear mixers consist of two electrical motors, one reduction gear, coupling, and shafts with two agitators. The shaft is sealed with special sealing, sometimes with an air purge, in a way that there is limited contact between the material and the seal. Materials are loaded from the top side, and the discharge is located at the bottom side. Due to the consistent modular design, the Vertical High Shear Mixers can be configured individually and easily adapted to the constructional circumstances and specific requirements.

High Shear Mixer Construction Material

Hywell Machinery is able to offer our GHJ series wet high-speed blender with contact parts to be built in SS304, SS316L, Titanium, Duplex stainless steel, etc. For the control system of the GHJ series wet high-shear mixer, Hywell has choices on push button, PLC+HMI, and so on, and For the main electrical components of the wet mixer, it can choices the famous brand such as ABB, Siemens, or Schneider or others.

How does the High Shear Mixer Works

In a Hywell Machinery GHJ series wet rapid mixer, the powders are set in a multidimensional shear flow state and it needs only a short mixing time until they are thoroughly mixed. In case high uniform blending is required, the spraying system sprays the binder solution into the bowl to agglutinate with the materials, and under the combined action of the impeller and chopper, the uniform wet powder is produced. After finishing the mixing process with the high-shear mixer, wet powders are discharged through the side discharge with a valve.

Components of a High Shear Mixer

Motor and Power Transmission System

The motor and power transmission system is the backbone of a high-shear mixer. It provides the power required to drive the impeller and chopper, which creates high shear forces. This section will discuss the different types of motors and power transmission systems used in rapid mixer.


The motor is the component that provides the power to drive the impeller and chopper. There are two sets of motors used in high-shear mixers: impeller motor and chopper motor. the impeller motor passes the gearbox to drive the impeller, but the chopper is directly driven by the chopper motor.

Power Transmission System

The power transmission system transmits the power from the motor to the impeller. There are two types of power transmission systems: direct drive and belt drive. Direct drive systems are more efficient because they have fewer moving parts and less energy is lost due to friction, but for the high shear blender, just the chopper is direct to driving by the motor. the impeller needs belt drive systems that are less efficient but allow for more flexibility in terms of impeller speed.

Jacket Vessel

Mixing Vessel

The mixing vessel is the container where the mixing process takes place. It is designed to hold the product being mixed and provide a space for the impeller to operate. In this section will discuss the different types of mixing vessels and their features.

Closed Vessel

A closed vessel is a container with a lid that is sealed to prevent the product from escaping.

Jacketed Vessel

A jacketed vessel is a mixing vessel with a heating or cooling jacket. The jacket is filled with a heat transfer fluid that circulates through the jacket, transferring heat to or from the product. Jacketed vessels are commonly used in the food and pharmaceutical industries.

The cooling and heating system is used to control the temperature of the product during the mixing process. It is essential for products that require a specific temperature range to maintain their stability and quality.


The impeller is the component that creates the high shear forces required for mixing. It is a rotating blade that generates a flow pattern in the product, causing it to mix and blend. In this section, we will discuss the different types of impellers and their functions.

Chopper (Shear Zone)

The shear zone is the area where the high shear forces are generated. It is the most critical component of a high-shear mixer and determines the effectiveness of the mixing process.

Control System

The control system is used to monitor and control the mixing process. It is essential for maintaining the desired mixing parameters and ensuring product quality. In this section, we will discuss the different types of control systems used in high-shear mixers.

Manual Control System

A manual control system is operated by a human operator who adjusts the mixing parameters based on their observation of the high-shear mixing process. Manual control systems are simple and easy to use but require experienced operators.

Automated Control System

An automated control system uses sensors and software to monitor and control the mixing process. It is more accurate and precise than a manual control system and requires less operator input. Automated control systems are commonly used in the pharmaceutical and chemical industries.

High Shear Mixers Working Principle

The working principle of high shear blender follows the following processes;

1. Mixing of the powder

The high-shear mixer machine starts with the mixing of the powder in a bowl using the impeller.

2. Addition of binder liquid

Next, the impeller proceeds to mix and spread the liquid also known as a binder at a speed between 5rpm – 300rpm

3. Dampening or wetting of the powder

The high-shear blending machine’s chopper breaks the wet lump to wet powder at a speed of 200 -3000rpm.

High Shear Mixers Advantages

Hywell machinery GHJ series vertical high shear mixers had the following advantages over conventional solutions.

1. Excellent homogeneity of mixing with no dead points

Maintenance and Cleaning

Maintenance and cleaning are essential for ensuring the longevity and effectiveness of a high shear mixer. In this section, we will discuss the different maintenance and cleaning procedures for high-speed mixers.


Lubrication is necessary to prevent wear and tear on the moving components of the high-shear mixer machine. Lubricants are applied to the bearings, gears, and other moving parts to reduce friction and extend the life of the components.


Cleaning is essential to prevent contamination of the product and ensure the quality of the final product. High-shear mixing machines should be cleaned after each use using appropriate cleaning agents and procedures.
