8.5 Operating procedures
8.5.1 Familiarize yourself with the performance of all equipment in this position and operate as required.
8.5.2 Before driving, carefully check whether the fastening screws, lubrication system, linkage devices and gates of the equipment are normal. Check whether the vacuum pump has cooling water, whether the baler or conveyor is normal, whether the hydraulic system is flexible, whether the air supply, water supply, and supply are normal, and whether the electrical systems are normal.
8.5.3 After the ceramic filter is turned on, the machine operation becomes the automatic control state. The filter plate must be cleaned once per shift, each time is 1 hour. If the filter plate is not cleaned, remove it with oxalic acid as required.
8.5.4 The operation of the ceramic filter is monitored according to the technical requirements of the equipment. If the power is suddenly turned off, the slurry in the tank should be emptied.
8.5.5 After the plate and frame filter press is turned on, the machine operation becomes the automatic control state. If the filtrate is mixed, it is necessary to replace the filter cloth or adjust the plate frame in time.
8.5.6 Conveyors, shakers and dryers are operated in accordance with the equipment operating procedures.
8.5.7 Do the following equipment lubrication work
Laser cutting is a process where a material is cut through the use of a laser beam. This can be for small & fine materials or materials with a much greater level of thickness (e.g. metal sheets). The process simply involves the use of a focused laser beam (e.g. pulsed or continuous wave) to cut a wide range of materials to a high level of accuracy, using a process, which is highly repeatable.
The laser beam can easily be programmed to precision cut a diverse range of thicknesses and materials (e.g. metals (including reflective metals such as copper, silver and aluminium) – brass, tungsten, steel, pewter and titanium etc.), gemstones (e.g. diamonds), ceramics, graphic composites, silicon and many types of plastics.
Even the most complex, awkward and intricate of shapes can be accurately cut through a Fiber Laser as the user has total control over the beam intensity, duration and heat input. Laser cutting has some similarities to other laser-based processes such as engraving and drilling, which also use a focused laser beam to effectively make designed cuts into a material.
