Yellow metal guardrails are installed around the pit, forming a unified protection system with the safety guardrails around the equipment. The conveyor frame, crusher frame, and silo support are all painted green and yellow, consistent with the colors of other equipment in the workshop. The cement foundation on the ground has been hardened, and the equipment foundation is tightly connected to the pit structure. There are stacks of boards and construction tools in front. This production line has entered the pre-commissioning stage and is planned to be connected to subsequent granulation, drying, and other processes.
