How to Procure Coal Processing Equipment That Fits Your Needs?

There are numerous options for selecting coal processing equipment, each with its own merits, which can be quite bewildering. Some learn from their mistakes, while others remain oblivious to them. Recently, a friend consulted me on this matter, prompting me to write this article on how to procure equipment that fits your needs.

Consider the following eight aspects: ① Self-assessment and scenario analysis. ② Product design features. ③ Processing and manufacturing capabilities, manufacturing standards. ④ Material selection. ⑤ Provision of spare parts. ⑥ Service commitments. ⑦ Recommendations from knowledgeable and competent friends. ⑧ Avoiding irresponsible sellers.

I. Self-assessment and Scenario Analysis

Firstly, it's essential to understand the problem you're trying to solve, the metrics you're aiming for, and the constraints you're facing. For instance, during a visit to a coking coal processing plant in Shanxi last year, I was puzzled to find an abandoned wind sorting workshop adjacent to the preparation workshop. It seemed the plant had been misled by the allure of "waterless, no medium" processing, resulting in costly lessons learned.

Another example involves processing "spontaneously combustible coal," where the challenge lies in its porous nature and high medium consumption during washing. In such cases, dense media separation is more suitable. In cold, water-scarce open-pit mines, water availability becomes the primary constraint. Dry separation machines can be employed to remove gangue, increasing calorific value.

Understanding your specific circumstances and needs is crucial for making informed equipment choices.

II. In-depth Understanding of Alternative Equipment Features

Similar products from different manufacturers may have distinct design solutions. Understanding these features and how they address specific issues can reveal valuable insights. Analyzing product brochures, technical presentations, and engaging in discussions with product developers can provide deeper insights, helping you avoid common pitfalls.

III. Processing and Manufacturing Capabilities, Manufacturing Standards

This is a critical aspect. Coal processing equipment belongs to the manufacturing industry, and the quality of products varies significantly between small workshops and large enterprises. Advanced processing equipment, manufacturing standards, and skilled technicians are not developed overnight. It's essential to assess a manufacturer's processing capabilities, either through public information or on-site inspections.

IV. Material Selection

The choice of materials, such as sieve plates for cross screens, significantly impacts equipment lifespan. Understanding the materials used in critical components like bolts, bearings, gearboxes, and motors is crucial. Ensure that material specifications are clearly defined in contracts.

V. Provision of Spare Parts

Some manufacturers adopt a strategy of selling equipment at low prices but charging exorbitant rates for spare parts. It's essential to ensure that spare parts are readily available and reasonably priced. Standardized components are preferable to proprietary ones to avoid being locked into expensive replacements.

VI. Service Commitments

For instance:

① Our company guarantees that the lifespan of screen shafts will reach four times the screen plate replacement cycle. If not met, we will replace the shafts free of charge.

② Within five years of equipment purchase, our company will provide cross-screen shaft assemblies at the originally supplied itemized prices.

③ Our company offers free labor for cross-screen shaft assembly repairs, only charging for replacement parts and return shipping costs, equivalent to the customer's on-site assembly costs.

Such commitments demonstrate integrity and help ensure long-term satisfaction with the equipment.

VII. Recommendations From Respected and Competent Acquaintances

Seek recommendations from trustworthy and knowledgeable contacts to build a reliable network of advice and support.

VIII. Avoiding Irresponsible Sellers

Ultimately, the party responsible for the outcome must be held accountable. Even seemingly straightforward processes may require oversight. Caution is always prudent.

In Conclusion

To procure equipment that truly fits your needs, it's essential to understand both your requirements and the available options thoroughly. Seek guidance from professionals, leverage your experience, and use contractual agreements to ensure your expectations are met. Effective communication and careful consideration of all factors will lead to satisfactory equipment procurement.
