Kneading of Green Sand

Eirich has more than seventy years of experience in manufacturing sand processing systems. The portfolio covers the entire sand processing chain, including sand recovery, sand cooling, return sand storage, sand preparation, and transfer to the molding line, for customers in Japan and overseas.
Eirich is the partner of choice when you are looking for solutions tailored to your needs, whether you are installing a completely new sand processing system, modernizing existing equipment, or partially upgrading your facilities.

At our Technical Center, we offer a flexible testing environment to meet a wide range of needs.We have test machines and measuring instruments that can handle everything from small raw material tests to scale-up trials. These facilities can be used to compare with your existing equipment or to develop new processes.We also provide rental options for our test machines and measuring instruments, so you can carry out sample production on your own.Please feel free to contact us.

Eirich Intensive Mixer is a high-speed mixer and granulator designed for a wide range of processing tasks involving raw materials, mixtures, and compounds.Optimal material processing is achieved by selecting the appropriate mixing tool shape and rotation speed according to the application.
By adjusting the operating conditions, a single machine can handle multiple processes such as mixing, granulation, kneading, and slurry preparation.The mixer features a jacketed mixing pan for both cooling and heating, and offers a wide range of customizable options to accommodate various processes.

Advantages of the Eirich mixing principles

1. Eccentrically positioned rotor tool (mixing tool)
   The rotor tool shape, rotation direction, and speed range can be selected to suit the application.
2. Tool Set (scrapers)
   It scrapes off raw materials adhering to the inner wall and bottom of the mixing pan, while simultaneously promoting efficient material transfer to the rotor tool.
3. Mixing Pan (mixing vessel)
   Through rotation, all raw materials in the mixing pan are continuously supplied to the rotor tool.

Unique Mechanisms

• Short mixing time and high homogeneity
• Capable of processing raw materials with varying specific gravities
• The rotating mixing pan promotes material movement and reduces residue.
• By selecting the rotor tool shape and adjusting the mixing pan speed, the system can handle complex material processing
• Process integration enables compact and energy-efficient production systems
• Setting optimal operating parameters ensures consistent and reproducible material processing
