70-90 TPH Gypsum Hammer Crusher Maintenance in Thailand
Why a structured maintenance program for your gypsum hammer crusher is essential for reliable operation in Thailand's growing construction materials sector
Thailand stands as the undisputed production and export hegemon in South-Eastern Asia's gypsum market, with its output of 9.4 million tonnes constituting 91 per cent of regional supply. This dominance not only satisfies substantial domestic demand but also generates a massive exportable surplus. The gypsum market size in Thailand stood at approximately USD 477 million in 2025 and is anticipated to reach nearly USD 622 million, expanding at an annualized rate of 3.5 per cent. For quarry operators and aggregate producers processing gypsum at 70-90 tonnes per hour, the hammer crusher is a critical piece of equipment in the processing circuit. Its reliability directly determines plant availability, throughput, and operating costs. A well-maintained hammer crusher can deliver years of consistent service, while neglect leads to costly breakdowns, reduced production, and premature equipment failure. Understanding the 70-90 TPH gypsum hammer crusher maintenance in Thailand is therefore essential for operators who want to maximise uptime, control costs, and maintain consistent production. At OCP Mechanical Company, with over 40 years of manufacturing experience, we supply hammer crushers engineered for gypsum applications, and we provide practical maintenance guidance to help Thai operators achieve long-term equipment reliability.
Understanding gypsum and its impact on hammer crusher performance
Gypsum is a soft sulfate mineral with a Mohs hardness of 2, making it one of the easiest materials to crush. Its low density and tendency to produce fine dust require careful equipment selection, but its softness also means that hammer crushers can process it efficiently with minimal wear compared to harder rocks. However, gypsum often contains inherent moisture, which can range from 2‑10 per cent depending on the deposit and seasonal conditions. In Thailand's tropical climate, with high humidity and significant rainfall during the monsoon season, moisture content can be higher, causing material to become sticky and leading to build‑up on the crusher components. For a 70-90 TPH operation, the feed typically consists of run-of-mine gypsum up to 200-400 mm, with the desired product size often being 0-10 mm or 0-20 mm for cement production, gypsum board manufacturing, and agricultural applications. The hammer crusher uses high-speed rotating hammers to generate strong impact force to crush the medium-hardness mineral ores like gypsum. Our hammer crushers are engineered with robust components and maintenance-friendly features, delivering reliable performance in gypsum applications. All product specifications, including capacity and power ratings, are continuously updated; for the latest parameters, please consult our online customer service.
Daily maintenance – the foundation of reliable operation
A disciplined daily maintenance routine is the first line of defence against unexpected breakdowns. Before starting operations, operators should perform a thorough pre-shift inspection. The foundation bolts of the hammer crusher must be tightened, and every lubrication point must be checked to ensure good lubrication. The hammer head wear should be inspected regularly and replaced in a timely manner. The screen plate should be checked for blockages and cleaned as needed. Bearings should be lubricated to ensure normal operation of the transmission device. The motor temperature should be monitored; under normal operating conditions, the temperature should not exceed 60°C. Bearing temperatures should also be checked, with the temperature rise not exceeding 30°C above ambient. During operation, operators should listen for unusual noises, monitor power consumption, and observe product consistency. After the shift, the crusher should be allowed to clear all material before shutdown. These daily checks, when performed consistently, catch developing issues before they become costly failures. Our hammer crushers are designed with accessible inspection points that simplify these daily checks, enabling operators to maintain consistent oversight.
Weekly maintenance – deeper inspections and proactive care
Weekly maintenance involves more thorough inspections and servicing. The lubrication system should be checked, with grease added to the bearings as needed. Bearing grease should fill approximately 50 per cent of the volume of its space. Each bearing should be lubricated after every 8 hours of operation, and the lubricating oil should be changed once every month to three months. The hammer heads should be inspected for wear patterns; uneven wear may indicate feed distribution issues or rotor imbalance. The screen plates should be checked for wear and blockages, and any build-up of material should be removed. The drive belts should be checked for tension and wear. The anchor bolts should be re-tightened if any loosening is detected. These weekly tasks prevent small issues from escalating into major problems. In Thailand's remote quarry regions, where access to specialised maintenance services may be limited, a disciplined weekly maintenance program is particularly valuable. Our hammer crushers are designed with maintenance-friendly features that simplify these weekly inspections. Prices are for reference only and are subject to change based on configuration and market conditions.
Monthly maintenance – comprehensive assessment and planning
Monthly maintenance involves a comprehensive inspection of all crusher components. The rotor should be checked for balance, as an unbalanced rotor can cause vibration and accelerate wear on bearings and hammers. The hammer heads should be measured for wear; when wear reaches 60-70 per cent of the original thickness, replacement should be planned. The screen plates should be inspected for wear and replaced if holes are enlarged or distorted. The bearings should be cleaned thoroughly and repacked with fresh grease. The electrical system should be checked, including emergency stops, wiring connections, and control panel functionality. Monthly maintenance also provides an opportunity to review production records, identify patterns, and optimise maintenance schedules. In Thailand's gypsum operations, where production targets are high and downtime is costly, this structured approach to monthly maintenance is essential for achieving consistent throughput and controlling operating costs.
Lubrication – the lifeblood of your hammer crusher
Proper lubrication is critical to preventing premature bearing failure. For hammer crushers processing gypsum, where dust generation can be significant, maintaining clean lubrication is essential. Each bearing should be lubricated after every 8 hours of operation. The lubricating oil should be changed once every month to three months, and the bearing should be carefully cleaned with gasoline or kerosene when changing the oil. Grease should fill approximately 50 per cent of the bearing cavity volume. Before each lubrication, the grease gun nozzle and the lubrication port should be cleaned to prevent contamination. In Thailand's tropical climate, where temperatures are consistently high, using the correct high-temperature grease is essential. An adequate charge of grease should be injected into the bearing housings before every cold start. Maintaining a rigorous lubrication schedule is essential for preventing the most expensive failures. Our hammer crushers feature accessible lubrication points that simplify this critical maintenance task.
Common problems and troubleshooting
Even with regular maintenance, operators may encounter common problems. Reduced crushing capacity is often caused by worn hammer heads, blocked screen plates, or material build-up in the crushing chamber. Solutions include replacing worn hammer heads, cleaning the screen plates, and adjusting the feed rate. Excessive vibration may be caused by an unbalanced rotor, loose mounting bolts, or worn bearings. Solutions include rebalancing the rotor, tightening all bolts, and replacing worn bearings. Overheating typically indicates bearing failure, insufficient lubrication, or overloading. Solutions include replacing bearings, checking the lubrication system, and reducing the feed rate. Material blockage in the crushing chamber is often caused by high moisture content or feed size issues. Solutions include reducing feed moisture, adjusting the feed size, and cleaning the chamber. By understanding these common problems and their solutions, operators can quickly diagnose and resolve issues, minimising downtime and maintaining production.
Thailand's operating environment – climate, power, and logistics considerations
Thailand's tropical climate, with high temperatures, high humidity, and significant rainfall during the monsoon season, places additional demands on crushing equipment. When you operate a hammer crusher in Thailand, you must consider the effects of moisture on material handling and equipment corrosion. The country's power supply is generally stable at 380V/50Hz, but voltage fluctuations can occur in remote quarry areas; we recommend using a voltage stabiliser or soft starter to protect the motor. Thailand's mining and quarrying sector consumes significant energy, with 40-50 per cent of electricity used for crushing and grinding. Logistics are well-developed, with Thailand's central location providing access to major transport routes connecting to regional ports. Our logistics team has extensive experience shipping to Thailand and can coordinate door-to-door delivery, including customs clearance. Importers of industrial machinery should be aware that certain equipment may require an import license, and TISI certification may be required for some products. We provide all necessary documentation for customs clearance, including certificates of origin and CE compliance.
