At present, China's spiral classifier has developed into a complete product line, with a total of 24 specifications, of which sorghum type single and double spiral classifiers have 8 or 6 specifications respectively, the spiral diameter is from 0.3 to 3.Om, sinking type, The double helix classifier has 5 specifications each, and the spiral diameter is from 1.0 to 3.Om. The low-end spiral classifier can be modified from the above spiral classifier.
Our spiral classifier manufacturer more, mainly Shen mine, Liaoning heavy, heavy south, Kunming Jinshan, all mine, Shen Ye, heroes, rather ore, heavy machine Nanchang, Liaoning research and development of magnetic mines Machinery Co., Ltd. (hereinafter Referred to as Liaoyan Magnetic and Yankuang, followed by Shicheng, Baotou, Zhengzhou and Wanquan.
Spiral classifier model meaning example 2FG (C)-10: 2 - double helix (single spiral not note), F - classifier (a few manufacturers write FL), G (C) - sorghum type (sink type ), 10 - spiral diameter (dm; a few manufacturers write l000mm).
1. Shen Mine The company is the largest manufacturer of spiral classifiers in China. The product specifications are also the most. The technical performance parameters are listed in Table 1. The external dimensions and installation foundation are shown in Figures 1~15.
The installation base diagram is as follows: 1 These drawings are only for reference when the design department designs the foundation, and the structural form of the foundation can be designed according to the actual situation; 2 because the installation inclination angle is determined by the process flow, the required support is installed. And the fastening parts are determined by the design department and are provided by the user; 3 The embedded parts should be fixed in the reinforced concrete beam and can withstand the shearing force and tensile force; 4 The height of the foundation should be customized by the user according to the position of the grinding machine. .
When ordering, it should be noted that when ordering Ф00, Ф50, Ф000, Ф200, Ф500 and Ф000 spiral classifiers, the user should indicate the screw speed. If not proposed, the spiral speeds of the first five are respectively 11.63, 7.8, 5.7. The V-belt pair corresponding to 6, 4r/min is supplied, and the spiral speed of Ф2000 is supplied by the motor corresponding to 3.6r/min.
2. Liaozhong The plant is the main manufacturer of small and medium-sized spiral classifiers in China. The product and technical performance parameters are listed in Table 2. The shape is shown in Figure 16. The shape and installation dimensions are listed in Table 3.
3. Nanzhong The spiral classifier produced by the plant and its performance parameters are listed in Table 4. The shape and installation dimensions are shown in Figures 17~19.
4. Kunshan Jinshan and various mines The spiral classifiers they produce and their technical performance are listed in Tables 5 and 6, respectively.
5. Shenye The plant produces a high-grade single-screw classifier. Its technical performance is listed in Table 7. The shape and installation dimensions are shown in Figures 20, 21 and Table 8, respectively.
6. Qunying The spiral classifier produced by the plant and its technical performance parameters are listed in Table 9. The shape and installation dimensions are shown in Figures 22~28.
7. Xinhai Mining Machine The company mainly produces four types of sorghum single helix and double helix, sunken single helix and double helix (Table 10). The single spiral classifier is divided into two types: traditional and improved. . The improved classifier adds an automatic sand returning device to the sand return end of the classifier to lift the ore discharged from the bottom of the tank to a proper position on the wall of the classifier to accommodate the removal of the head with the ball mill . After the configuration. After the mill cancels the large spoon, the energy per ton of ore can generally save 1-1.5kWh, while avoiding the frequent maintenance of the large spoon, and slowing the wear of the ball mill's large and small gears, the mill operating rate is improved, and the power saving effect is obvious. . After the mill cancels the configuration of the scoop head, it has no influence on the classification performance and grinding ability of the classifier.
8. South Mine The company produces sunken and sorghum single helix and double helix classifiers; and produces single and double helix stone washers and sand washers, suitable for construction sites, sand and gravel plants and other units for larger particles. Washing, grading and dewatering of smaller granules are listed in Tables 11-14.
9. Other plants The spiral classifiers produced by Ning Mine, Nanchang Heavy Machinery, Yankuang, Shicheng and other plants and their technical performance are listed in Tables 15~19.
