With the rapid development of China's basic industries, the market demand for gravel sand materials is increasing day by day, which also prompted the large and small gravel plant, stone field to flourish. Sand making equipment is the core of the gravel production line, which is crucial to the entire production line. The sand making airport more dust, equipment used for a period of time there will be dust attached or material sticky. If not cleaned up, not only harm the sand making machine, but also reduce the production efficiency of the sand making machine, which may result in blockage of the discharge opening of the sand making machine and reduce the comprehensive sediment yield of the whole production line.
So sand on a regular basis to clean up the dust, remove internal dirt and material sticky or is necessary. To a certain extent, to avoid losses. So how should the sand making machine maintenance and repair? How to clean the dirt inside the sand making machine? Our Henan Kefan sand making machine manufacturers, based on practical experience and customer feedback, summed up in time the following real and effective sand making machine Descaling and cleaning methods.
The most effective and effective sand cleaning method, commonly used in the following three:
So which method should be used to clean the gray scale with the sand making machine? This depends on the type of sand making machine used by the user, the nature of the dirt and the degree of scaling.
Therefore, before cleaning in addition to understand the type of heat exchanger, structure and geometry and size, it is important to understand the type of scale and scaling degree, in order to configure the appropriate cleaning fluid configuration of the cleaning fluid Although there are some calculations However, field tests are still to be carried out by taking samples from representative fouling sites, analyzing them and performing dissolution tests to determine their solubility and then the solvent type, dosage and cleaning time used in the sand making machine.
Mining equipment cleaning is divided into pickling and caustic washing, first introduced pickling, the hydrochloric acid solution will be roughly 20 percent, such as mechanical dirt Department, parked for about ten minutes and then rinse with a cleaning solution, pay attention to this method Hydrochloric acid solution should be configured into the water and constantly stirring, it is prohibited to pour water into hydrochloric acid, alkali wash, we must first start the generator, in 20 kilograms of water plus 1.5 kilograms of caustic soda and 0.5 kilograms of kerosene configuration Into the cleaning solution into the dirt Department, with cleaning rods constantly cleaned lye is dissolved in the dirt, and finally clean water tail. Regardless of acid or lye, is a certain corrosive metal, so you must grasp the ratio of cleaning fluid and cleaning time, the degree of control.
