Commonly Used Stone Crushers and The Maintenance

In the sand and gravel aggregate production line, crusher, as the key core equipment, plays a key role in the whole production line. Especially under the fierce market competition, many enterprises and individuals have gradually entered the sand crushing production industry, and the related crushers must be comprehensively compared based on the different uses of the industry needs, to make sure the selection of crushers is effective and reasonable.

This article will tell you how to maintain 4 types of commonly used stone crushers and how to effectively improve their performance.

Jaw crusher

Jaw crusher has the characteristics of simple structure, stable operation, wide application range of materials, simple operation and low maintenance rate, but it is necessary to regularly check and replace the wearing parts such as dynamic and static jaw plate and side protection plate.

In the process of daily maintenance, it is necessary to check the eccentric shaft, the dynamic jaw plate and the lining plate of the jaw crusher, pay attention to the long-term continuation of this work. In addition, it is necessary to clean up these key components in time, and do a good job of recording, maintenance, replacement and other work.

• 1. Regularly inspect and maintain the machine: Check the machine regularly for any signs of wear and tear, loose bolts, and other issues. Lubricate the bearings and other moving parts as needed. Replace any damaged or worn-out parts promptly.
• 2. Keep the machine clean: Clean the machine regularly to prevent the accumulation of dust and debris, which can cause damage to the machine. Use a brush or air gun to remove any debris from the machine.
• 3. Use the correct jaw die profile: The jaw dies are the most important wear parts of the jaw crusher. Use the correct jaw die profile for the material being crushed. This will ensure that the jaw dies wear evenly and last longer.
• 4. Optimize the feed: Make sure that the material being fed into the jaw crusher is evenly distributed and not oversized. Oversized material can cause damage to the machine and reduce its performance.
• 5. Adjust the CSS: The CSS (closed side setting) is the distance between the jaw plates at the bottom of the crushing chamber. Adjusting the CSS can control the size of the crushed material and improve the performance of the machine.
• 6. Monitor the wear of the jaw plates: Regularly monitor the wear of the jaw plates and replace them when necessary. Worn-out jaw plates can cause uneven wear and reduce the performance of the machine.
• 7. Train operators: Train operators on how to operate the machine correctly and safely. This will help prevent accidents and ensure that the machine is used in the most efficient way possible.

By following these guidelines, you can maintain and improve the performance of your jaw crusher, which can help increase productivity and reduce downtime.

Cone crusher

During the working process of cone crusher, it is necessary to ensure continuous and uniform feeding of materials to achieve full chamber crushing of the crusher to improve the production capacity and crushing efficiency, and to avoid situations such as eccentric feeding, insufficient feeding, excessive material smaller than the tight edge discharge port (generally≤10%), and high powder content in the material. At the same time, the material to be crushed should not exceed 80% of the maximum feeding size allowed by the specific model of the cone crusher.

In general, we can adopt the following methods to improve the production effect of cone crusher:

Before starting or stopping, it is necessary to establish an effective operation and maintenance mechanism based on the actual situation to ensure the normal start of the cone crusher;

Reasonably select and design the particle size, feeding amount, and distribution method of the material to avoid abnormal shutdown;

Choose proper lubricant to promote good lubrication between the lubrication parts of the cone crusher;

Establish and improve the daily inspection system;

Reasonably arrange the monthly, quarterly, and annual inspections of equipment to form a practical operation and maintenance system, and establish emergency measures.

Impact crusher

The impact crusher is mainly suitable for coarse, medium, and fine crushing of soft and medium hard materials, and also has a certain shaping effect. The particle size of the material after impact crushing is relatively good.

Impact crusher has many advantages, such as practical, low power consumption, and lower operating cost.

However, there are also certain shortcomings, including the presence of high dust content during the crushing process. During operation, it is necessary to regularly check the wear of the impact plate and impact block, and adjust the gap between the impact frame and rotor timely according to production needs according to the required particle size and output capacity to determine the appropriate discharge port.

Hammer crusher

Hammer crushers are used to crush a variety of materials, including coal, limestone, and gypsum. To maintain a hammer crusher and ensure that it operates at its best performance, you can follow these general guidelines:

(1) Before starting the machine, it is necessary to conduct a comprehensive and detailed inspection of the control equipment before the crusher process to determine the reliability of the equipment, and also to ensure that the functions of the crusher.

(2) During the startup process, make sure that there is no debris and materials in the crushing cavity. And feed the raw material to the crusher after a few minutes of no load running. And ensure that every shift needs to check the bearing, hammer head and bolt, to avoid loosening of bolts, bearing oil shortage, hammer head excessive wear.

(3) Regularly inspect the operation of the motor and the temperature rise of the bearings to reduce the occurrence of safety accidents.

(4) After production, the operator must check whether all the materials in the hammer crusher have been completely discharged. If they are not discharged or there are impurities, they need to be completely removed.
