To prepare a good quality wet sand casting, you must use the excellent performance of the wet sand. Excellent quality wet sand available, in addition to the need to use high quality raw materials, it also needs to have a reasonable formula, a set of ideal sand-processing equipment, but also have to have good sand processes. Some domestic foundry is not bad, although the raw materials, sand-processing equipment is basically complete, but the mixed system of the wet sand performance is not good enough, but there are many drawbacks. For example, the most frequently encountered problems are the following: the amount of bentonite added a lot of sand, sand is also high enough blue smoke, sand machinery, but low wet strength, low toughness, from the model of the poor, much sand in the sand beans casting sand hole deficit. Most of these problems are due to the poor security Mixer poor maintenance of equipment, machinery quotation sand, sand poor preparation, lack of sand power input and other causes. In addition, sand machinery manufacturers, problems encountered in some factories that discharge a large amount of waste sand mixer S11 series of rolling wheel is mainly used for foundry sand and a single noodle mixture of sand, can also be used for large-scale foundry mixed system core sand and from the hard sand. Features: Sand high efficiency, good quality and wide range. Diabase, tungsten carbide surfacing, 2 fillers and other new materials, greatly improving the life of wearing parts. The adoption of two national patents, technical parameters meet JB / T2656-91, advanced technology, reasonable structure. Hydraulic coupling, alloy steel gear, lubrication controlled machines to ensure smooth and reliable transmission system, and can load start. Rotary discharge door (patent 98240318.6) open and flexible, and reliable. Steel base greatly facilitate the use and installation by rolling mill wheels, rub the mixture of mixture of sand making sand machine called the grind wheel Mixer. Grind wheel Mixer batch mixer is mainly used for clay, mixed sand. It is equipped with two grinding wheels, two blade, grinding wheel has rolling, rubbing action, mechanical action sand, moisture, clay, other addenda evenly distributed in the sand surface, squeegee loose sand block and so do not mix the sand blew DRUM, to continue rolling, kneading, mixing until all the sand.
