How to maintain the hydraulic system of a hydraulic cone crusher

A hydraulic cone crusher is a typical crushing equipment for medium and fine crushing of hard materials. It adopts the principle of layer compression crushing to achieve selective crushing of materials. It has four cavity types: medium crushing, medium-fine crushing, fine crushing, and ultra-fine crushing, which can be adjusted according to the user's production requirements to obtain the desired particle size. Hydraulic cone crushers are widely used in medium and fine crushing operations for various minerals and rocks, serving as a key crushing equipment for achieving ‘more crushing, less grinding.’ They are extensively applied in industries such as metal mines, metallurgy, chemicals, sand and gravel aggregates, and cement, capable of crushing materials like river pebbles, granite, basalt, limestone, dolomite, and other non-ferrous and ferrous metal ores.

Cone crushers often operate under heavy-duty conditions and in harsh environments. Therefore, maintaining the lubrication system's oil lines unobstructed, ensuring clean oil quality without leaks, and ensuring normal operation are essential for ensuring the proper functioning of the cone crusher. Therefore, we must focus on the following three points for the daily maintenance of the cone crusher's lubrication system:

1. Select appropriate lubricating oil. Lubricating oil is the key component of the cone crusher's lubrication system. When selecting lubricating oil for the cone crusher's lubrication system, it is essential to choose high-quality thin oil to ensure optimal performance of the system. To avoid damage caused by poor-quality oil, it is recommended not to purchase lubricating oil of uncertain quality for cost-saving purposes. Additionally, it is important to note that different lubricating oils may have varying properties, so they should not be mixed.

2. Control the lubricating oil temperature. Before starting the cone crusher lubrication system, the return oil temperature must first be measured. The oil temperature of the cone crusher lubrication system is monitored and controlled by a heater, cooler, thermometer, temperature switch, and return oil thermometer, ensuring that the oil temperature remains stable within a certain range.

3. Ensure proper dust protection for the lubrication system. The working environment of the cone crusher is highly dusty, so it is important to maintain proper dust protection for the lubrication system. Regular cleaning should be performed to prevent blockages in the lubrication channels, which could impair the normal operation of the lubrication system.
