Why Does Spherical Graphite Agglomerate During Coating and Carbonization? Causes and Fixes
You open the carbonization furnace and find that a batch of free-flowing spherical graphite has turned into cakes. After screening, there are far more oversized particles than expected. Particle size distribution is off target, and tap density is drifting. The first question on the floor is usually, “Did we add too much pitch?” Sometimes that’s […]
Pitch vs Resin: How to Select a Carbon Coating Precursor for Natural Graphite
Many new natural graphite anode producers hit the same moment. The spheroidized, purified samples are finally done, and the customer’s first questions are about the coating. What precursor did you use? What’s the initial efficiency? How does it perform at high rates? Behind those questions sits one decision: which carbon coating precursor to use, pitch […]
From Lab to Pilot to Plant: How to Scale Up Natural Graphite Anode Processes Without Costly Surprises
A natural graphite anode sample looks great in the lab. Capacity is on target, first-cycle efficiency is solid, and the particle size sits right where you want it. So the team decides to scale up. A few months later, the first production batches come off the line with a wider particle size distribution, tap density […]
Complete Equipment List for a Natural Graphite Processing Plant: A Planning Checklist
A natural graphite anode plant typically needs equipment for drying, milling, spheroidization and classification, purification, magnetic separation, pitch coating, carbonization, screening, and packaging. Unlike synthetic graphite, natural graphite does not need a graphitization furnace. The carbonization step, done in a rotary kiln, roller hearth kiln, or pusher kiln, is central to coating quality. Key takeaways […]
How to Build a Natural Graphite Processing Plant: A Step-by-Step Guide for New Anode Material Producers
Introduction Many teams planning a natural graphite processing plant start with one question: which spheroidization equipment should we buy? Equipment matters, but it is rarely the only thing that puts a project at risk. Delays and budget overruns often come from decisions made around the equipment. The purification route may prove a poor fit for […]
Granulation Kiln Maintenance Checklist: Preventive Tips for Longevity
Regular maintenance of a granulation kiln is critical to avoid unexpected downtime and costly repairs. This comprehensive checklist outlines preventive tasks that operators and maintenance teams should perform daily, weekly, monthly, and beyond. Implementing these steps helps maintain product quality and extends the lifespan of your granulation kiln. The Importance of Routine Granulation Kiln Maintenance […]
Final Product Handling for Graphite: The Complete Guide for Global Manufacturers

This guide covers the entire spectrum of final product handling for graphite, from storage and packaging to transport and quality control, providing actionable insights for manufacturers and logistics professionals […]
How to Choose the Right Final Product Handling System for Graphite Plants
Selecting the optimal final product handling system is one of the most critical decisions for any graphite powder plant. In the competitive landscape of the new energy industry, particularly for lithium battery anode materials, the difference between success and failure often lies in the last stage of production. A high-performance system ensures product purity, operational […]
How to Precisely Control Natural Graphite Particle Size Distribution Using a Coating Rotary Kiln
Introduction In anode material production, if mechanical spheroidization is the step that shapes graphite particles, then coating granulation is the step that defines their performance. For natural graphite producers, the Particle Size Distribution (PSD) of the final product is far more than a routine quality metric — it directly governs the tap density, first-cycle Coulombic […]
