Calcium Carbonate Plant in Thailand
Calcium carbonate ultrafine grinding plant in Thailand. HGM and LUM mill configuration producing 1250-2500 mesh GCC for paint and plastic. Case study with results.
This case study presents a detailed account of a real-world grinding mill installation project by LIMING, including project background, equipment selection rationale, installation process, commissioning results, and ongoing operational performance. The information is based on actual project data and customer feedback, providing valuable reference for similar projects.
Project Overview
A Thai plastics compounder in Saraburi province invested in an integrated GCC grinding and coating plant. The facility produces stearic acid-coated calcium carbonate for PVC and polyolefin masterbatches at 3-5 t/h.
Integrated Grinding and Coating
The production line combines an HGM100P ultrafine mill for primary grinding to 1250 mesh, followed by a powder surface modification machine for stearic acid coating. The coating machine uses a heated chamber with high-speed paddles to evenly distribute stearic acid on particle surfaces.
Product Quality
Coated GCC powder achieved activation degree of 98%, with a contact angle of 110 degrees confirming hydrophobic surface treatment. When compounded into PVC at 30% loading, the coated GCC improved tensile strength by 15% compared to uncoated powder. The client replaced imported coated GCC with their own product, reducing raw material costs by 40%.
Project Insights & Lessons Learned
