Precautions when using sand making machine

In artificial sand production, aggregate processing, construction waste recycling and mineral fine crushing industries, the sand making machine is the core equipment for producing high‑quality manufactured sand. Standardized operation and daily management are critical to reduce unexpected failures, extend service life of components and keep stable production capacity. As a professional sand making machine factory, Shanghai Dongmeng sorts out key operating precautions to guide global users to run the sand making machine safely and efficiently.

Inspection work before starting the sand making machine

Before power‑on startup of the sand making machine, operators must complete full‑range inspection. Check tightness of all bolts and fasteners, confirm no loose parts caused by long‑time vibration. Inspect wear conditions of impact blocks, lining plates and other vulnerable components inside the crushing chamber. Clear blocky materials and sundries left inside the cavity. Check lubrication system, oil level and oil quality to guarantee no oil leakage. Verify connection status of driving motor, belt tension and protective devices. Never start the sand making machine with existing faults inside the equipment.

Matters needing attention during equipment operation

The sand making machine must run under no‑load condition for several minutes after startup. Only when vibration, noise and rotating status show normal can feeding work begin. Feeding materials shall conform to the designed maximum feed size; over‑size stones and unbreakable metal objects are strictly forbidden to enter the crushing chamber. Keep uniform and continuous feeding, avoid partial feeding which will cause uneven wear of wearing parts. Observe operating status in real‑time: abnormal vibration, sharp noise or sharp temperature rise shall trigger immediate feeding stop for troubleshooting, do not continue production under faulty state.

Discharge gap and particle size adjustment specifications

The finished sand grain type, fineness modulus and output are closely related to discharge gap of the sand making machine. Adjust the gap according to raw material hardness and finished‑sand requirements. After each adjustment, run short‑time test production to check particle quality. Do not arbitrarily modify equipment parameters beyond the factory setting range, otherwise it may cause component overload and hidden safety risks.

Lubrication and daily maintenance requirements

Good lubrication is the guarantee for long‑term stable operation of the sand making machine. Fill in qualified lubricating grease on schedule, replace lubricant according to working hours. Regularly check abrasion of impact hammer, guard plate and flow‑guide sleeve. Replace severely worn accessories in time. Clean dust and material accumulation on the equipment surface after each shift. Establish complete operation and maintenance records to grasp the real‑time condition of the machine.

Correct shutdown procedure

When stopping production, first cut off material feeding, wait until all materials inside the crushing cavity are completely discharged, then shut down the sand making machine host. The lubrication system should keep working for a period for heat dissipation. Avoid emergency shutdown with materials remaining inside the cavity, otherwise material blockage will appear for next startup.
