Working Procedure for Power Screen Crusher

Safe and efficient operation of a Power Screen crusher is paramount to achieving optimal production output while ensuring personnel safety and equipment longevity. This standardized procedure outlines the critical steps involved in its operation.

1. Pre-Operational Checks & Preparación

Equipo de protección personal (EPI): Ensure all personnel in the vicinity are wearing mandatory PPE: hard hat, safety glasses, high-visibility vest, protección auditiva, and steel-toed boots. Gloves are recommended when handling materials or performing adjustments.
Work Area Inspection: Clear the area around the crusher of personnel, obstacles, debris, and any tools not in use. Verify adequate lighting and ventilation.

Machine Inspection:
Integridad estructural: Visually inspect the crusher frame, guards, cae, tolva, and discharge points for any signs of damage, cracks, or excessive wear. Pay special attention to liners.
Fasteners: Check that all bolts, nuts, and other fasteners are tight and secure.
Guards & Safety Devices: Ensure all safety guards (drive guards, nip point guards) are correctly installed and functional. Verify emergency stop buttons are accessible and operational.
Lubricación: Check fluid levels (hydraulic oil, engine oil if applicable) according to the manufacturer's specifications. Inspect grease points; lubricate bearings and moving parts as per the maintenance schedule.
Sistema de accionamiento: Inspect belts for proper tension (refer to manual), alineación, and signs of wear or damage. Check V-belts for fraying or glazing.
Cámara de trituración: Visually inspect the chamber for any foreign objects or material buildup from previous operations. Remove any obstructions safely (ensure power is OFF/LOTO applied).
Electrical Connections: Look for damaged cables or loose connections (qualified personnel only).

Material de alimentación: Verify the material to be crushed meets the crusher's specifications regarding maximum feed size and material type. Remove oversized material or contaminants beforehand.

2. Startup Sequence

1. Comunicación: Signal clearly to all personnel that startup is imminent ("Clear the area!").
2. Engine/Power Unit Startup (Si corresponde): Start the power unit according to its specific procedure. Allow it to idle until operating temperature is reached.
3. Crusher Motor Startup:
Ensure the crushing chamber is empty.
