Sand is a widely used in the foundry industry sand processing equipment, Mixer by sand process characteristics, can be divided into: the rolling action-oriented research ﹑ rubbing rolling wheel Mixer; mixed effect based blade mixer; rub both research ﹑ counterflow mixing or said rotor type mixer and mixing both ﹑ rolling pendulum wheel Mixer. Mixer according to the nature of work can be divided into two kinds of intermittent and continuous mixer. By rolling mill wheel rub sand mixture and mix to make a mixer called grind wheel Mixer. Grind wheel Mixer is a batch mixer is mainly used for sand, mixed clay. It is equipped with two grinding wheels, both blades, grinding wheels have rolling, rubbing effect, so that water, clay, other addenda are uniformly distributed in the sand surface, so that the blade block loose sand, and no mixing of DRUM blown sand, to continue rolling, rubbing, and mix until all the sand. Rotor type sand mill maintenance rules 1, according to the product operating instructions should be checked regularly and bottom liner and the blade gap lined circle between when the gap is too large to be adjusted. Without prejudice to the blade movement the gap should be adjusted to a minimum. When should the timely replacement of badly worn scraper blade and vane. 2, periodically check the use of the rotor blade. When the blades wear serious sand resin sand equipment manufacturers, should be replaced. But when replacing sand equipment, must pay attention to the mounting direction of the blade sand resin sand equipment company, should not hold against. Otherwise it will seriously affect the life of the blade. 3, always check the amount of lubricating oil each reducer. Should regularly check the lubrication of the upper bearing rotor reducer. Shandong resin sand sand equipment, 300-500 hours of use, they should be replaced after the first time the lubricant. Later in normal use, about six months to replace with new oil. Before replacing the new oil deal with reducer internal cleaning. At the same time remove the oil filter and magnetic plug cleaning. When refueling, the oil must be filtered to 140 mesh strainer. 4, regularly carry out professional electrical parts inspection. 5, good maintenance and repair records, maintenance process must be put up eye-catching overhaul nameplate resin sand sand equipment manufacturers around the circle on top of the machine, sand equipment, provided by Qingdao Heng Heng Machinery Co., Ltd.
