A Jaw Crusher is a crushing tool used in the mining and construction industries to break down large rocks into smaller sizes. This tool operates with two jaws: one fixed and one movable, driven by a drive system.

Rocks are fed into the space between the two jaws, and the movable jaw crushes the rocks against the fixed jaw with pressure.

The jaw crusher problems that often occur in the mineral mining industry and their solutions are as follows:

1. Problem: High Load, Low Speed, and Dusty Environment

Machinery and equipment that handle heavy loads require significant power, often resulting in slow operational speeds. Additionally, the dusty environments common in these locations can worsen machine conditions, causing faster wear, increased maintenance needs, and potential damage to critical components. The combination of high load, low speed, and dusty environments creates significant challenges in maintaining the performance and longevity of the equipment.

Solution: Molykote Long Term 2 Plus

This specialty grease is designed for lubrication needs across various industries, offering a solution to the aforementioned problems due to its features and benefits:

• Capable of operating under high loads
• More resistant to water and dust
• Resistant to cold and heat (-30 to 130°C)
• Does not easily melt
• Economical, as it does not easily melt
• Longer regreasing intervals
• Metal-to-metal protection
• Corrosion protection
• NLGI 2 (normal grease)

Please contact our experts for lubrication consultation for your industry.

2. Problem: Rusty Bolts, Difficult to Remove

Rusty bolts that are difficult to remove on a jaw crusher are a common issue in the mining and construction industries. Harsh environmental conditions, including continuous exposure to moisture, dust, and chemicals, accelerate the corrosion process on bolts.

When these bolts rust, they become very hard to remove, hindering routine maintenance and repair processes. This increases downtime, reducing efficiency and raising operational costs.

Comprehensive solution products from Eonchemicals include:

Molykote P40
This is a highly recommended paste lubricant for preventing rusty bolt issues. Molykote P40 is suitable for all types of assembly work and continuous lubrication, particularly in corrosive environments such as areas with water splashes or high humidity. Its features and benefits include:

• Corrosion protection
• Strong adhesion
• Water-resistant
• Excellent anti-fretting

Molykote GN Plus
This solution product also functions like Molykote P40, preventing rusty bolt issues that are hard to remove. Molykote GN Plus is a solid paste lubricant for the assembly and operation of metal components, including bolt installation. Its features and benefits include:

• Prevents friction and abrasion corrosion
• Good anti-corrosion properties
• Reduces fretting corrosion formation
• Simplifies disassembly processes
• High load-bearing capacity
• Low friction coefficient
• Protection from stick-slip

Please consult with our experts to get more precise product recommendations for solutions in your industry.

EonPen 100
While the two Molykote products above function as preventive measures, EonPen 100 is used if you already have rusty bolts that are difficult to remove.

EonPen 100 is a penetrating fluid, which can penetrate, lubricate, and release rusty and stuck parts. This product is the best solution for loosening bolts that are hard to remove due to rust. Its features and benefits include:

• Excellent penetration ability into bolt threads, effectively dealing with bolts that are hard to open
• Pleasant, non-pungent aroma
• Suitable for application on machinery and electrical equipment

3. Problem: Lubricant Dries Quickly

Lubricants that dry quickly can negatively impact machinery or equipment as they do not provide sufficient protection against friction and heat generated during operation. Consequently, machine components such as bearings, pistons, and gears can wear out faster. Additionally, quickly drying lubricants require more frequent re-lubrication, leading to inefficiency.

Our solutions for this problem include:

Molykote Long Term 2 Plus
Molykote Long Term 2 Plus is a special type of grease that excels in handling heavy loads and is suitable for long-term lubrication applications.

Molykote BR2 Plus

This lubricant is resistant to drying out, making it an ideal solution for your problem. It has high load-bearing capacity, provides reliable and long-lasting protection against friction, extends the lifespan of components, and maintains optimal machine performance in hard-to-reach conditions. Its excellent oxidation resistance ensures stability under various operational conditions.

Its ability to form an oil film helps reduce component wear and offers effective corrosion protection. Additionally, this lubricant has good water resistance, enhancing lubrication reliability in wet environments.

4. Problem: Abrasive and Quickly Worn Due to Transfer Points and Chutes

This problem can lead to reduced equipment lifespan and more frequent maintenance needs, reducing overall operational efficiency.
