Cone Crusher Counterweight guard

The cone crusher counterweight guard, a protective and structural component surrounding the counterweight and eccentric bushing, functions as a safety barrier against rotating parts (500–1500 rpm), blocks contaminants, reinforces stability, and reduces noise.​ Structurally, it consists of a 4–8 mm thick annular body (Q235/Q355B steel or HT250 cast iron), mounting flanges with bolt holes, 1–2 access doors, reinforcement ribs, ventilation slots, lifting lugs, and an 80–120 μm corrosion-resistant coating.​ Manufactured via steel plate welding (plasma cutting, rolling, MIG welding) or sand casting (1380–1420°C pouring) with annealing, it undergoes CNC machining for flange flatness (≤0.5 mm/m) and surface finishing. Quality control includes material testing, weld inspection (DPT), impact testing, dust tightness checks (0.1 MPa pressure), and safety validation (ISO 13857 compliance).​ This ensures reliable protection and durability in mining/aggregate operations
