Mixing tools Mixing plough The DISA TM Turbine Mixer delivers unbeatable reliability, precision, durability and cost-efficient operation. Robust design, precision engineering and quality components combine with the latest process control technology to make the DISA TM superior in every way. DISA TM Mixer Important features • Efficient and economic operation due to high throughput rate and short mixing cycles • High casting quality due to homogeneous and fluffy moulding sand of consistently high quality • Full integration into any sand circulation system using the intelligent control system •...

Design and function Features that make the difference Economic and precise mixing system The mixing tools rotate continuously during loading with pre-batched material. The large double “S”-shaped mixing ploughs and the high-capacity blenders (one or two depending upon mixer size), which are mounted from above, rotate in opposite directions, while the mixing pan and guide ploughs remain stationary. This combination guarantees fast, highly intensive preparation as well as perfect homogenization of the moulding sand. • Exceptionally economic operation due to high throughput rate and improved energy...

Control systems Control Units • Main control panel • HMI PC with graphic display • Local operator panel • Sand Multi-Controller, SMC Main control panel The main control panel with a Siemens S7 PLC controls all the functions of the mixer. The controlled equipment and functions include mixer motors and cycle, water dosing systems, weighing, SMC and additive dosing systems. The control includes automatic bad batch rejection. The mixer system is based on a recipe control with 99 different recipes that can be pre-defined. Recipe number, time, target values and achieved values are stored in log files...

Sand control Sand Multi-Controller, SMC The SMC measures compactability and sand strenght from a 50 mm test sand sample extracted from the mixer. Water is added to the mix based on the compactability measurements. As options, the SMC can include measurements of return sand temperature and moisture before the mixer. This is particularly relevant for low moisture contents, or for return moisture contents and sand temperatures with large variations. From the sand strength measurements, the bentonite requirements are calculated and can be adjusted in small increments in following batches towards...
