The grate is the core of the whole technology, our company adopts the advanced mechanical reverse push grate, so that the movement direction of the garbage and the movement direction of the grate is opposite to each other, which plays a very good effect on the mixing and transportation of the garbage. The grate consists of several parts, including grate frame, movable and static grate sheet, and driving system. On each row of grate frame, the fixed grate sheet and the moving grate sheet are arranged alternately in rows, and the moving grate sheet rows make reciprocating reverse push movement on the fixed grate sheet rows.
