Product introduction

      Cross screen is a kind of roller screen. It is a screening equipment developed on the basis of traditional roller screen. At present, there are many problems in the use of traditional roller screen in the market, such as blocking, winding, poor sealing, powder leakage and so on. In view of the problems existing in the traditional roller screen, our company has developed a new cross screen product, which can fundamentally solve the disadvantages of the traditional roller screen In terms of the working conditions (dry, wet and sticky materials), Guosheng cross screen demonstrates its screening ability with excellent efficiency and reliability, while keeping the maintenance cost at a low level.
 
 Cross screen

working principle

The screen surface of the cross screen is composed of several groups of screen shafts rotating in the same direction. A number of equidistant screen pieces are installed on each screen shaft. The screen pieces on the adjacent screen shafts are arranged in a cross way. Under the screen pieces, there are mud scraping plates to clean up sticky particles, so as to ensure the screen hole permeability in the screening process. In the rolling process, the material is continuously layered, the small particles move down, and the large particles roll forward. It is a new screening equipment.
 
 Cross screen manufacturer
 
The application of cross screen in coal handling system of thermal power plant is the most common. The equipment is used in front of the coal crusher to screen out the materials on the screen that are larger than the screen hole in the coal, and move forward on the screen conveying surface, and are sent to the coal crusher for crushing, and the materials smaller than the screen hole directly fall into the equipment under the screen machine by their own gravity.

Difference between cross screen and roller screen

Roller screen is a mature product, its advantages and disadvantages are also known, and can make effective preventive pre judgment. The cross screen is relatively new equipment, and the unknown risk needs to be calculated.   
      The two equipments are similar in appearance, but in fact, the screening mechanism is different. The cross screen adopts the screening mechanism of "dynamic mesh" in which the screen pieces are crossed to form a screen hole, while the roller screen does not cross, and the screen hole is a "static screen hole". Therefore, in terms of screening wet viscosity, the cross screen has great advantages, and inherits the advantages of the roller screen, and can also be used It can avoid the blocking and blocking of traditional roller screen.
