Cement plants, steel mills and rolling mills, ore grinding.
Open gears on kilns and mills carry extreme loads in dust; bearings face heat and shock; grease consumption is high.

screw air compressors of 22–75 kW monitored Aug 2022 – Jul 2023; this article presents three representative machines. Objective: verify the hydrocracked mineral air compressor oil CPI-9370-46 under air-compressor conditions in Vietnam (hot discharge, dusty and humid compressor rooms) and use oil analysis to set the change interval for each machine.

Plastics · Cement · Textiles · Binh Duong (now Ho Chi Minh City), North Central Vietnam, Dong Nai · Aug 2022 – Jul 2023Work Hop Tien has done at plants in this industry, and technical articles on the lubrication points this industry meets most.
Which oil your screw compressor needs is written on the machine itself: the manual, the oil label on the door and the discharge temperature under load. How to read all three and decide when to change the oil.
TechnicalTrade names change; base oils do not. How the four base oils in rotary screw compressor oil behave in Vietnamese conditions, why they cannot be mixed, and a table of which switches need a drain and which a full flush.
TechnicalViscosity, TAN, water, iron, copper and silicon: what each one says about a screw compressor, with reference limits and three common patterns.
