The continuous development of technology in refractory industry requires improvement

Selection and arrangement of screening equipment for multi particle materials the screening equipment commonly used in refractory production is two-layer screen or three-layer screen. The layout type can be parallel or vertical as described above. However, with the continuous development of refractory industry technology and the increasing requirements for refractory materials, more particle size ingredients must be used in actual production in order to improve the physical and chemical indexes of products, which requires the application of four or more layers of screening equipment. Production practice has proved that if the four layer screen is arranged as a whole, its screening efficiency is low. Therefore, the arrangement form of two double-layer screens in series can be adopted, and the screening efficiency of this split structure can be greatly improved. Several improvements in process equipment installation design. Structure type of screen feeding reflux system in the design of crushing system, a combined unit composed of cone crusher and double roll crusher is usually used to improve the output of the unit, that is, the screen feeding of cone crusher is used as the feeding material of double roll crusher, and its feeding structure is that a gate is set in the straight chute before the screen feeding into double roll to control the material flow. This structure not only aggravates the manual operation in front of the machine and is not easy to adjust the feeding amount, but also easy to cause dust leakage due to poor sealing. Therefore, an intermediate buffer chute with a certain capacity is added in the screen feeding reflux system, and then feeding with the feeder can better solve the above problems.

The cushion function of the material itself is used to reduce wear and noise. The structure type of feed port of double roll crusher is improved by taking Bi 61ommx40mm double roll crusher as an example. The diameter of the improved flange becomes smaller, and some materials can be stored in the surrounding space above the flange. At the same time, the materials can fall on the double roller gap to a large extent and less on the fast-rotating roller. Therefore, the wear of materials on the flange is reduced and the noise is reduced. In order to reduce the wear of materials on the equipment foundation, the discharge structure of double roll crusher is improved. The discharge structure of other crushers can also be improved.
