In Uzbekistan, a local company sought to capitalize on its abundant calcite resources to develop a high-grade calcium carbonate project. However, the outdated milling equipment in use could not meet the technical requirements for product quality. After attending a domestic trade show, the company discovered Zhengyuan, whose advanced technology and extensive experience in ultra-fine processing of non-metallic minerals stood out, particularly in the ultra-fine grinding and surface modification of heavy calcium carbonate. The company decided to partner with Zhengyuan and upgraded its entire calcite processing operation, becoming a leading supplier of high-quality calcium carbonate powder in the region.

An Indian client required equipment to mill high-purity silica powder with specific needs for fine particle size, high whiteness, low metal contamination, and high production capacity. After testing equipment from various manufacturers in India and China without success, the client encountered Zhengyuan at the Canton Fair. Impressed by Zhengyuan’s air jet mill technology during their visit and trial, the client soon placed an order. The results exceeded expectations, and the company has since become a leading supplier of high-end silica powder in India.
