Daily Maintenance & Care Tips for Stone Crushers

A Global Practical Guide to High Output and Low Consumption

In the global mining and sand aggregate industry, stone crushers serve as the core equipment of production lines, and their operating status directly determines the profitability of projects. Whether dealing with hard cobblestones or highly abrasive granite, scientific and efficient maintenance is not only the key to extending equipment service life but also a compulsory course to reduce downtime losses. Among numerous brands, Shanghai Dongmeng equipment has won wide trust from customers worldwide with its outstanding reliability and user-friendly maintenance design.

Refined Maintenance of Core Components
For crushers, bearings and lubrication systems are equivalent to the heart and blood. The technical team of Shanghai Dongmeng recommends that global users follow the principle of oil replacement by quality and regular cleaning. Generally, the grease added to the bearing housing should be controlled at 50%–70% of the volume, and it should be completely replaced every 3 months or according to local working conditions (such as high temperature and dust). Especially in low-temperature winter environments, grease with excellent low-temperature performance must be selected to prevent startup difficulties caused by increased viscosity.

Take Shanghai Dongmeng tracked mobile jaw crushing station as an example. Its design fully considers the complexity of field operations. Operators must check the wear of the movable jaw plate and fixed jaw plate before startup to ensure no foreign matters in the crushing chamber. The standard hydraulic system of Shanghai Dongmeng equipment is equipped with overload protection, which requires maintenance personnel to regularly check for leaks in hydraulic pipeline joints. This is critical to ensure the equipment can automatically remove obstacles and protect the main machine when encountering unbreakable materials.

Special Maintenance for Different Models
Shanghai Dongmeng's product line covers the whole process of primary crushing, secondary/tertiary crushing and shaping, with different maintenance priorities for various models.

Mobile Impact Crushing Station: This type of equipment processes medium-hard and soft materials, so the wear speed of blow bars and impact liners is relatively fast. Shanghai Dongmeng main engines adopt heavy-duty rotors and high-wear-resistance alloy blow bars. During maintenance, the frame can be easily opened with a hydraulic opening device, greatly shortening the time for replacing wearing parts.

Mobile Cone Crushing Station: As the main equipment for secondary/tertiary crushing, its independent design of hydraulic and lubrication systems is a major highlight. Shanghai Dongmeng multi-cylinder hydraulic cone crusher is equipped with a fully automatic control system. Maintenance personnel should pay attention to the automatic compensation data of liner wear on the computer screen, and use one-key automatic startup and fault diagnosis functions to predict hidden dangers in advance and realize condition-based maintenance.

Quarterly & Annual In-depth Maintenance
In addition to daily and monthly inspections, seasonal in-depth maintenance is equally important.
Minor repair every 3 months: Focus on checking the tension of motor belts and the uniformity of wearing parts.
Major overhaul every year: Clean up accumulated materials inside the main engine, inspect and repair electrical circuits.

As an industry leader, Shanghai Dongmeng’s advantages lie not only in the excellent quality of jaw crushers, cone crushers, mobile crushing stations and other equipment, but also in its full-life cycle services. From equipment selection to daily operation and maintenance training, Shanghai Dongmeng’s service team can customize solutions for you to ensure your crushing production line is always in optimal performance.
