For the gasification unit in the northwest, the coal screening device located before the crusher requires the following parameters: 450-500 T/h, feed size less than 250 mm, and material passing through the screen to be less than 20 mm. What type of screen would be suitable in this case? ? ?
It is recommended to use a composite sine screen. A composite sine screen is a screening device for solid materials in industries such as coal, power generation, metallurgy, cement, and mining; it is particularly suitable for the dry classification of coal in coal mines, coal washing plants, and thermal power plants. It is particularly suitable for particle size classification of 13 mm or larger. Currently, the screening equipment used in coal mines, power generation, mining, and metallurgy includes traditional types such as rotary grid screens and reciprocating grid screens, as well as more advanced types like probability screens, inertial vibration screens, and roller screens. Products such as drum screens can no longer meet the requirements of large-scale industrial production. Probability screens, inertial vibration screens, and roller screens also have drawbacks such as low screening efficiency, high power consumption, susceptibility to damage, high noise levels, and substantial maintenance requirements. These issues affect the screening of solid materials in industries such as coal, power generation, mining, and metallurgy to varying degrees, and can even disrupt the normal operation of entire systems. The composite sine screen is a new type of screening equipment developed by analyzing the shortcomings of various existing screening devices and drawing on the production experience from industries such as coal and power generation; it has been granted a **patent**. The greatest feature of this product is that its screening principle relies not on vibration screening, but rather on the perturbation effect of sine waves for screening, thereby completely overcoming the many disadvantages associated with vibration screens. This product features a unique structure, high processing capacity, efficient screening performance, reliability and durability, easy maintenance, and low noise levels. Its technical performance is at the leading level both domestically and internationally; its processing capacity, screening efficiency, environmental friendliness, and reliable operation all meet the requirements for grading solid loose mixtures.
