Precautions for sand making machine before operation and empty-load operation

Sand making machine is widely used in the production of building aggregates, road fabrics, cushion materials, asphalt concrete and cement concrete aggregates. Mainly used for artificial sand making of river pebbles, mountain stones (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, and stone chips.

Preparations before the trial operation of the sand making machine

1 Plan the process of commissioning before commissioning.
2 The equipment body and surroundings should be clean, the power source and the materials to be processed must also meet the design requirements. And the necessary lighting and communication facilities should be provided.
3 Check and confirm that there are no metal foreign objects or any other objects in the hammer machine.
4 Check whether all fasteners are loose, and whether the access door and hole cover are sealed.
5 Check that each lubricating point is used with qualified grease.
6 Dangerous locations should be equipped with safety protection facilities and markings. The test personnel should stand in the specified safe area. And the rest of the personnel are not allowed to stay in the test area.

Matters needing attention in the operation of sand making machine with no load
