Mixer is to carry out experiments with sand casting process Experimental Research of important equipment Mixer equipment prices, experiment with Mixer, regardless of grinding wheel or rotor. Qingdao bowl Mixer equipment, plus the amount of sand are a 3 kg, the normal temperature of conventional experimental research performance (core) sand is mainly used type. When these studies the performance of sand mixer for tens or hundreds of grams per gram only by the amount of sand, such as thermal expansion when research will result in a waste of quality raw sand and binder, increasing the cost of experiments . In order to solve these problems, we have developed a first sand was only 250 g of experiments using a micro-mixer. The micro-rotor type mixer has a simple structure, easy operation, adjustable parameters, the advantages of a small amount of sand, the experimental verification of the quality of the sand, mixed with sand to reach the laboratory machine requirements, while reducing raw material consumption, reduce the cost of experiments in order to prepare a good quality wet sand casting, you must use the excellent performance of the wet sand. Wet sand get excellent quality, 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 a good sand processes. Although some domestic raw materials used foundry sand is not bad equipment, sand processing equipment is basically complete, but the wet sand mixed system performance is not good enough, but there are many shortcomings. For example, the most frequently encountered problems are the following: the amount of bentonite added a lot of sand, sand high enough to absorb the amount of blue sand equipment specifications, but the low wet strength, low toughness, from the model of the poor, sand and more sand beans casting sand hole deficit. Most of these problems are due to poor Mixer equipment repair warranty poor, poor preparation of sand, sand shortage of power input and other causes. In addition, the problem encountered is that some plants discharge a large amount of waste sand with the development of high-speed high-pressure molding automatic production line and the emergence of a mixed system of the new green sand clay mixer. Such Mixer structure is characterized by eccentric parts installed in the chassis above mixer speed of the rotor blade and with a blade chassis clockwise rotation of the rotor and blades for counterclockwise rotation, the rotor speed is higher than chassis speed. When sand, due to a sand mill having a rotor chassis opposite movement, and different speed, then the molding sand in the chassis to obtain a different speed difference generated between the sand and the shearing force corresponding to the frictional force, resulting in a mixed ﹑ ﹑ rubbing RESEARCH crushing and other effects, not only high efficiency, mixed, mixed system out of the sand quality stuff.
