我国目前已建成50多座重介质选煤厂,使用重介质旋流器的选煤厂有30多家,几乎都配有程度不同的自动化装置。我国的选煤自动化水平与先进的美、日、德、澳等国基本相当。实现选煤自动化,可以提高产品的产量,稳定产品质量,提高劳动生产率,减少操作人员,改善操作条件,其经济效益和社会效益是相当可观的。 At present, more than 50 heavy medium coal preparation plants have been built in our country. There are over 30 coal preparation plants using heavy-medium cyclones. Almost all of them are equipped with automation devices of different degrees. The level of automation of coal preparation in China is basically the same as that of advanced countries such as the United States, Japan, Germany and Australia. To achieve automation of coal preparation can improve the output of the product, stabilize the product quality, improve the labor productivity, reduce the operating staff and improve the operating conditions, the economic and social benefits are considerable.
