继角螺旋衬板或简称CZ衬板(又称方形圆角衬板)之后,又出现一种新型衬板,称为沟槽衬板,如图所示。该图是衬板组装在磨机内壁的情况。该衬板表面有三道沟槽,它们在磨机内壁组装时形成一道道的环向沟槽。 奧地利专家系统地研究了一般衬板被钢球磨损成沟槽的现象后得出结论:衬板不应做成阶梯形状,而应做成沟槽状,即在磨内壁形成一道道的环向沟槽。根据这个结论而设计成这种最新式的沟槽衬板。这种衬板能更有效地利用磨壁处的能量,装在粗、细磨仓均能取得满 Following the angle spiral lining or simply CZ lining (also known as square fillet liner), there is a new type of liner, known as the trench liner, as shown. This figure shows the case where the lining is assembled on the inner wall of the mill. There are three grooves on the surface of the liner, which form a circular groove in the inner wall of the mill. Austrian experts systematically studied the phenomenon of wear of general liner board by grooved ball and concluded that the liner board should not be made into a staircase shape but should be made into a groove shape that forms a hoop ring in the inner wall of the wear wheel Trench. Based on this conclusion, this latest type of trench liner is designed. This liner can more effectively use the energy at the mill wall, installed in the rough, fine grinding can be made full
