Dulbert F15 Formation Cutter

In the highly competitive coal mining industry, the performance of cutting picks directly impacts the cost and efficiency of coal mining operations. Today, we visit a coal mine in Inner Mongolia to see how Duerbote cutting picks help them overcome the challenges of pick usage and achieve cost reduction and efficiency improvement.

1. Initial Challenges: Low Wear Resistance of Cutting Picks Leads to Mining Bottlenecks

This coal mine in Inner Mongolia operates two shearers, with the rock hardness in the main mining area reaching F6, which is classified as medium to high hardness. Previously, the mine used U95 cutting picks produced by a major domestic manufacturer. Initially, the mine had high expectations for this well-known brand, but during actual use, a series of frustrating issues emerged.

During daily mining operations, the mine staff found that the wear resistance of these cutting picks fell far short of expectations. Due to the high hardness of the rock, the picks frequently and intensely rubbed against the rock, causing the pick heads to wear out extremely quickly. While the plan was to keep pick consumption within a certain range per shift, the actual situation was a significant increase in pick consumption, leading to a sharp rise in costs.

Moreover, frequent pick replacements became the norm. Each replacement required stopping the machine, which not only consumed a lot of time but also disrupted the tight mining schedule, significantly reducing operational efficiency. The mine’s management was deeply troubled by this and urgently needed a more wear-resistant and durable cutting pick to change this situation.

2. A New Attempt: Partnering with Duerbote U95 Alloy Bean Cutting Picks

After extensive inquiries and market research, the Inner Mongolia coal mine learned about Duerbote’s U95 Alloy Bean cutting picks. Duerbote has a strong reputation in the cutting pick industry, and its mature technology and reliable product quality caught the mine’s attention. With a trial mindset, the mine decided to purchase a batch of Duerbote U95 Alloy Bean cutting picks for testing.

3. Remarkable Results: Significant Improvement in Wear Resistance, Cost and Efficiency Both Enhanced

When the Duerbote U95 Alloy Bean cutting picks were put into use, the results were immediate. Compared to the previously used cutting picks from the major domestic manufacturer, the wear resistance of Duerbote’s U95 Alloy Bean picks showed a significant improvement. After the same shift of operation, the wear on the picks was greatly reduced, and the pick heads maintained excellent cutting performance.

In terms of consumption data, after switching to Duerbote picks, the mine’s pick consumption decreased by nearly 40%. This meant that the frequency of pick replacements, which had previously been high, was now significantly reduced. Not only did this lower the procurement costs for picks, but it also greatly reduced the downtime required for replacements.

Operational efficiency also saw a notable improvement. Without the need for frequent停机更换截齿, the shearers could work continuously and stably, accelerating the mining progress. The mine staff happily reported that since using Duerbote’s U95 Alloy Bean cutting picks, coal mining operations had become smoother, and mining efficiency had increased by approximately 30%.

4. The Secret Behind the Success: Duerbote Cutting Picks’ Core Strengths

The outstanding performance of Duerbote’s U95 Alloy Bean cutting picks can be attributed to mature technology and high-quality materials. In terms of materials, the pick heads are made of a specially formulated alloy that not only offers high hardness but also excellent wear resistance and impact resistance, enabling stable performance even when dealing with F6 hardness rock. The pick body is made of high-strength alloy steel, treated with special heat processes to ensure good toughness, allowing it to withstand the powerful impacts during mining and reducing the risk of breakage.

In design, the Duerbote U95 Alloy Bean cutting picks have undergone extensive simulation tests and real-world validation. The unique pick shape design effectively reduces cutting resistance and minimizes friction between the pick and the rock, further enhancing the pick’s wear resistance.

5. Customer Feedback: Recognition and Trust

The management of the Inner Mongolia coal mine highly praised the changes brought by Duerbote’s U95 Alloy Bean cutting picks. They stated that Duerbote picks not only solved the long-standing issue of low wear resistance but also tangibly reduced mining costs and improved efficiency. In today’s highly competitive coal industry, Duerbote cutting picks provide strong support for efficient and stable production. The mine expressed its intention to continue collaborating with Duerbote and will recommend Duerbote products to other coal mines in the industry.
