Dongguan LECJX Machinery Technology Co., Ltd. is a high-tech joint-stock company specializing in the R&D and production of wet grinding equipment, incorporating advanced German grinding technology. We focus on the field of material grinding and provide fineness solutions. With extensive and advanced production processes, our technology represents the forefront of international grinding standards. Our trademark registered in China is "勒驰" (Lechi), with the English brand "LECJX," and our products are protected by the Chinese patent authority.

Designed in compliance with German DIN industrial standards and European EMC product standards, our equipment has also obtained ISO international standard certification.

Through the research and application of advanced fluid dynamics and mechanochemistry, LECJX has developed core technologies for high-efficiency grinding components. We optimally integrate scientifically validated grinding processes with high-quality grinding equipment to deliver efficient, high-energy ultra-fine dispersion and nano-grinding solutions for wet grinding applications. Our current product range includes wet nano pin-type horizontal bead mills, wet disc-type horizontal sand mills, wet basket sand mills, laboratory nano sand mills, vacuum dewatering machines, and high-energy dispersers. These are widely used in high-end industries such as industrial coatings, inks, paints, food (chocolate, cocoa powder), pharmaceuticals, cosmetics, fine chemicals, ceramics, mineral processing, papermaking, cellulose, pesticides, batteries, and nano new materials. The ground products exhibit a narrow particle size distribution, with third-party Malvern laser particle size analyzer or TEM tests confirming a minimum fineness of D97 ≤ 70nm for materials like CaCO₃.

With the growing application of new energy and nano new materials, enhancing industrial structure, product quality, and process levels in the grinding field has become a key trend in the dispersion and grinding market. LECJX has established its own modern nano laboratory and adheres to the philosophy of providing precise grinding and ultra-fine dispersion solutions. We work closely with customers to explore optimal processing workflows and offer tailored solutions, recommending suitable nano-level and sub-micron grinding equipment.

Leveraging our production base and R&D center in Dongguan, along with a dedicated sales team and a rigorous German-inspired work ethic, LECJX continuously invests in product development, improvement, and innovation. Key grinding components such as grinding assemblies, ultra-wear-resistant alloy pin shafts, and double-ended mechanical seals use imported German parts. Furthermore, our drive, feeding, frequency conversion, and sensor systems are supported by leading international suppliers including ABB, Siemens, Ingersoll Rand, and SKF. This ensures the high quality, efficiency, and stability of LECJX ultra-fine grinding machines, enabling us to provide ideal solutions—from small laboratory equipment to complete production lines.
