Why Choose GarnetLM as Your Waterjet Garnet Supplier

Jiangsu LM Mining Co., Ltd. (GarnetLM) was established in 2007 in Lianyungang, China. We are a professional, vertically integrated garnet enterprise covering mining, processing, research and development, and distribution.

With proved reserves exceeding 6 million tons across multiple mine sites in China, plus imported alluvial garnet from overseas sources, we supply both Rock Garnet and Alluvial Sea/River Garnet to fully meet the diverse needs of the global waterjet market.

LM Mining's annual production capacity exceeds 80,000 tons, with 40% serving the domestic Chinese market and 60% exported to Europe, the Americas, the Middle East, and Southeast Asia.

GarnetLM We believe high-quality products come from scientific management and production. Every batch of garnet is produced strictly according to ISO 9001 quality management system requirements, using advanced wet processing and complete testing to guarantee consistent quality.

Waterjet Product Line

Rock Garnet 60# for Waterjet
Particle range: 0.20–0.50 mm. Recommended nozzle bore: 1.02 / 1.27 mm. Ideal for cutting granite, marble, and thick stone slabs. Angular grains deliver maximum cutting aggression for heavy-duty applications.

Rock Garnet 80# for Waterjet
Particle range: 0.15–0.35 mm. Nozzle bore: 0.762 / 1.02 / 1.27 mm. The general-purpose workhorse for ceramics, stainless steel, aluminium, and mixed metal jobs.

Rock Garnet 120# for Waterjet
Particle range: 0.10–0.18 mm. Nozzle bore: 0.508 / 0.762 mm. Fine-grade for glass, rubber, and precision CNC profiles requiring the smoothest possible edge finish.

Alluvial Sea Garnet 80# for Waterjet
Naturally sub-angular particles from coastal deposits. Same 0.15–0.35 mm range. Preferred for high-accuracy cutting on ceramics, stainless steel, and aluminium where kerf taper and surface finish are critical.

Alluvial Sea Garnet 120# for Waterjet
Ultra-fine alluvial garnet (0.10–0.18 mm) for glass cutting and detailed engraving. Inherently low dust, sub-rounded shape minimises micro-chipping on brittle materials.

12-Step Production Process

GarnetLM operates a fully integrated wet processing line with these stages:

4-Stage Crushing: Jaw → cone → fine → rod mill
6-Cycle Washing: Including sluice washing, gravity separating, rotating sand washing
Gas-Generator Drying: Moisture reduced to ≤0.2%
Cyclone Dust Removal: Residual airborne fines extracted
Magnetic Separation: Ferrous contaminants removed (≤0.09%)
Negative-Pressure Dust Collection: Final dust extraction
Precision Screening: Multi-deck vibrating screens per ISO 11126

Every shipment comes with a COA from our Quality Inspection department, tested against ISO 11126 and 11127 standards. This ensures consistent high quality from mining through processing to the end user.
