DISA SMC

Product catalog summary
Introduction
The document discusses the DISA SMC system, which is crucial for maintaining optimum sand quality in mould production, thereby enhancing the performance of casting processes. It is designed for use with DISA SAM mixers and other high-capacity mixers.

Specifications
The DISA SMC system automatically regulates and monitors the sand mixing process, ensuring consistent sand quality through in-mixer analysis. Key measurements include compactability and sand strength, with optional moisture content analysis.

Key Advantages
  • Improved sand quality control through automatic laboratory testing of each batch.
  • Precise water addition based on compactability rather than just moisture content.
  • Reduced cycle times by 10-20% for dry return sand with additional moisture control.

Key Features
  • Supports up to 99 different recipes and 3 different sand types.
  • Online monitoring and control via Siemens S7 PLC.
  • Automatic rejection of bad batches.
  • Compact and easy to install, compatible with all high-capacity mixers.

Procedures
The DISA SMC process involves controlling the sand preparation in a batch mixer. Compactability and sand strength are measured from a 50 mm sand test sample. The system adjusts water and bentonite additions to achieve desired sand properties.

Additional Features
  • Optional moisture control for dry and swinging return sand conditions, allowing up to 100% pre-water addition and reducing cycle times.
  • Integrated control and water dosing in DISA mixers, with independent systems for other mixers.

Programming and Monitoring
The DISA SMC program monitors alarms and logs all relevant values for each batch, ensuring comprehensive oversight of the sand mixing process.

Sand sample testing Water dosing panel Optimum sand quality in each batch The purpose of the DISA SMC is to control the sand preparation process in a batch mixer. Based on a 50 mm sand test sample the compactability and sand strength are measured directly. The basis for the required sand properties is defined by the operator via a recipe editor. Compactability The compactability determines the quantity of water to be added into the mixer by an electronic water dosage system. The SMC adjusts the water addition to attain the required compactability, and compensates automatically for varying fines...
