Precautions for Using Mobile Crushers

If protective measures are not taken in a timely manner during the use of a mobile crusher, the equipment may be prone to corrosion and operational issues, which can affect its efficiency and fail to achieve the expected results. Below are key precautions to consider when using a mobile crusher.

Precautions for Using Mobile Crushers

1. Impact of Temperature on Mobile Crushers
   During operation, each component has its own normal temperature range. When using a mobile crusher:
   • Avoid overloading at low temperatures: Ensure normal operation during the low-speed preheating phase to allow the machine to reach the specified temperature before driving or operating. Do not overlook this step just because no immediate issues arise.
   • Prevent operation at high temperatures: Regularly check the values on various temperature gauges during operation. If a problem is detected, stop the machine immediately for inspection and address any faults. If the cause cannot be identified, do not allow the machine to continue operating with unresolved issues.
   • Check cooling systems: For water-cooled machines, check and replenish cooling water before daily operation. For air-cooled machines, regularly clean dust from the air-cooling system to ensure unobstructed heat dissipation channels.
2. Impact of Impurities on Mobile Crushers
   Mechanical impurities typically include dust, soil, and other non-metallic substances, as well as metal shavings and wear products generated during the use of the mobile crusher. If these impurities enter the machine and reach the mating surfaces, they can cause significant damage by:
   • Impeding relative motion and accelerating component wear.
   • Scratching mating surfaces, damaging the lubricating oil film, increasing component temperature, and causing oil degradation.
     Tests show that when mechanical impurities in lubricating oil reach 0.15%, the wear on the engine’s first piston ring increases by 2.5 times the normal value. When impurities enter rolling bearings, their lifespan decreases by 80% to 90%.
   For mobile crushers operating in harsh or complex environments:
   • Use high-quality, compatible components, lubricating oil, and grease to block the source of harmful impurities.
   • Implement proper mechanical protection at the worksite to ensure mechanisms function normally and prevent impurities from entering the machine.
   • For faulty machines, seek repairs at professional facilities whenever possible. During on-site repairs, take protective measures to prevent dust and impurities from contaminating newly replaced components before they are installed.
3. Impact of Corrosion on Mobile Crushers
   Corrosion occurs when metal surfaces undergo chemical or electrochemical reactions with the surrounding environment, leading to damage. This corrosion not only affects the normal operation of the machine’s external surfaces but also corrodes internal components. For example, rainwater, chemicals in the air, or other substances can enter the machine through external channels or gaps, corroding internal components, accelerating wear, and increasing mechanical failures. Since corrosion is often invisible and easily overlooked, its harm is particularly significant. During use, management and operators should take effective measures based on local weather and air pollution conditions to reduce chemical corrosion. Key actions include preventing rainwater and airborne chemicals from infiltrating the machine.

Overview of Mobile Crushers
A mobile crusher, also known as a crawler mobile crusher, is an innovative rock-crushing equipment that expands the concept of coarse crushing operations. Its design philosophy prioritizes the customer’s perspective, aiming to eliminate obstacles caused by the crushing site and environment. It provides customers with efficient, low-cost hardware facilities for project operations.
