DISA SAM Mixer - Design and features The SAM mixer is a fast, intensive mixer for the production of high strength and high quality clay bonded sand. Fast, accurate and uniform sand preparation The SAM mixer produces the consistently high quality sand necessary to attain good castings with lowest reject rates. Mixing intensity and uniformity High-intensity mixing ensures uniform coating of all sand grains, maximum bonding forces, and reduced costs for excess bentonite and additives. Short cycle times Short cycle times (no dry cycle necessary) result in high output rates, coupled with limited temperature...

DISA SAM Mixer - Function Easy maintenance Unsurpassed accessibility, easy parts exchange and reduced maintenance requirements mean more uptime and faster service. Design and function The bowl is a strong, welded construction with a convex top section supporting the complete drive unit. A rotating arm and central shaft carry the mixing turbine, wall scraper, pan plough, directional vane and water sprays. The high-speed mixing turbine circulates around the stationary bowl. A full size wall scraper and pan plough, together with an adjustable guide vane, throw the sand into the path of the circulating...

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...
