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 & Preparação

Equipamento de proteção individual (EPI): Ensure all personnel in the vicinity are wearing mandatory PPE: capacete, óculos de segurança, high-visibility vest, proteção 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, destroços, and any tools not in use. Verify adequate lighting and ventilation.

Machine Inspection:
Integridade Estrutural: Visually inspect the crusher frame, guardas, cai, tremonha, and discharge points for any signs of damage, rachaduras, ou desgaste excessivo. Pay special attention to liners.
Fixadores: Check that all bolts, nozes, and other fasteners are tight and secure.
Guardas & Safety Devices: Ensure all safety guards (dirigir guardas, nip point guards) are correctly installed and functional. Verify emergency stop buttons are accessible and operational.
Lubrificação: Check fluid levels (óleo hidráulico, 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 acionamento: Inspect belts for proper tension (refer to manual), alinhamento, and signs of wear or damage. Check V-belts for fraying or glazing.
Câmara de esmagamento: 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 alimentação: 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. Comunicação: Signal clearly to all personnel that startup is imminent ("Clear the area!").
2. Engine/Power Unit Startup (Se aplicável): 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.
