1. The vibrating screen machinery should be developed in the direction of high efficiency and productivity. The modernization of industry enlarges the range of the enterprises. And the functions of the sand making equipment are becoming more. Besides, it can be equipped with the vibrating screen which is of high efficiency and productivity.
2. The vibrating screen should be developed in the direction of standardization, serialization, and generalization. In this way, it is convenient to make plans, conduct professional production, and to guarantee the high quality and low cost. On the basis of the three different vibration tracks of the vibrating screen, according to the special requirements in different industries, several kinds of vibrating screens are produced and widely used in industrial sectors.
In the departments in metallurgical industry, the vibrating screen is widely accepted by the mineral processing plants and sand making plants. Firstly, ores are screened in advance and screened for inspection by the vibrating screen, which means that the finished products of the ore grinding machine are classified by the vibrating screen and that in this way the grade of the concentrate can be increased. In the departments in coal industry, the vibrating screen can be used for the dehydration and medium drainage of the clean coal and slack coal.
In the departments of the water conservancy and electric power or heat-engine plants, it is necessary to screen ores in advance. For example, the gravel should be classified by the vibrating screen in the Three Gorges Project. It is needed in transport sector, and so on. The vibrating screen has been the key screening equipment.
3. The vibration intensity of the vibrating screen should be increased. The vibration parameters of the vibrating screen can be increased in order to reach a larger speed and acceleration.
4. Besides, it should be developed in the direction of being light-weight, of environmental protection, and simple layout. It is hard to replace the sieve of the out-dated vibrating screen, made in the 80s. There are 48 bolts, used to fix the sieve, on each layer. It takes, at least, 4 hours to replace a sieve. And the powder of high mesh is very likely to leak out from the bolts. In the industrial departments, with the constant increase of the demand of the vibrating screen, the old-fashioned vibrating screen will be washed out.
