How much do you know about the classification of grilles? Follow the Designer Metal Grilles from China manufacturer editor for a brief understanding of it!
According to the shape, the grid can be divided into two types: plane grid and curved grid. The plane grid consists of grid bars and frames. Curved grilles can be divided into fixed curved grilles and rotary drum grilles. According to the net spacing of the grille bars, it can be divided into three types: coarse grille (50~100mm), medium grille (10~40mm) and fine grille (1.5~10mm). Flat grille and curved grille can be made into coarse, medium and fine. Since the grille is an important facility for physical treatment, the newly designed sewage treatment plants generally use two grids of coarse and medium, or even three grids of coarse, medium and fine. According to the cleaning method, the grid can be divided into two types: manual cleaning and mechanical cleaning. Manual slag cleaning grid is suitable for small sewage treatment plants. When the amount of screen slag is greater than 0.2m3/d, in order to improve the labor and sanitation conditions of workers, mechanical slag cleaning screens should be used.
