今后几年,国家建材局拟在全国建材行业中推广以下节能新技术:1.磨机采用进相机,每台进相机,一年可节电5万至15万千瓦时。2.磨机使用节能型衬板,如圆角方形衬板。3.水泥回转窑、立窑、玻璃窑风机采用液力偶合器调速和降低启动电流,每台风机年可节电10万千瓦时左右。4.球磨机安装沟槽衬板,如在Φ2.2×6.5m磨机上使用,全年可节电65万千瓦时,可省球段20吨。5.水泥立窑上采用预加水成球技术,一年可节电15～20万千瓦时。6.在Φ1.83～24米的生料磨和水泥磨上采用锥带分级衬板,每吨水泥可节电10万千瓦时,增产9%至19%。
The next few years, the National Building Materials Bureau intends to promote the following energy-saving building materials industry in the new technologies: 1. The mill into the camera, each into the camera, a year can save 50,000 to 150,000 kilowatt hours. 2. Mill using energy-saving liner, such as rounded square liner. 3. Cement rotary kiln, shaft kiln, glass kiln fan using hydraulic coupling speed and reduce the starting current, each fan can save electricity about 100,000 kilowatt hours. 4. Ball mill installation trench liner, such as Φ2.2 × 6.5m mill on the use of electricity throughout the year can save 650,000 kwh, the province can save 20 tons. 5. Cement kiln on the use of pre-water into the ball technology, a year can save 15 to 200,000 kwh. 6. In the Φ1.83 ~ 24 meters of raw material mill and cement mill using tapered belt grading liner, each ton of cement can save 100,000 kilowatt hours, an increase of 9% to 19%.
