From Barite Rock to API-Grade Weighting Agent: How Your Plant Works
Raw Barite Crushing & Storage – Raw barite ore (≤600 mm) is crushed in a jaw crusher to <100 mm, then a hammer crusher or impact crusher reduces it to ≤20 mm. The granules are stored in a buffer silo for continuous mill feed.
Precise Dosing & Mill Feeding – The crushed barite is fed into the grinding mill at a controlled rate via a weighing belt feeder. The feed rate is automatically adjusted to maintain optimal mill load and classifier current.
Closed-Circuit Grinding & Classification – The ball mill (or Raymond mill) grinds the barite to powder. The mill discharge is air-conveyed to a high-efficiency turbo classifier. On-spec powder (97% passing 200 mesh) passes through; coarse particles return to the mill for regrinding. This ensures a sharp top cut and high density.
Product Collection & Cooling – The finished barite powder is collected in a baghouse filter and passed through a product cooler to reduce temperature before storage.
Quality Control Sampling – An automatic sampler collects a representative sample every hour for density, particle size, and BaSO₄ content testing in the on-site lab.
Packaging & Dispatch – The API-grade barite powder is stored in product silos, then packed into 25/50 kg bags, 1.5-ton bulk bags, or loaded directly into bulk tankers. A weighbridge ensures accurate billing.

· Barite Ore Analysis & Pilot Grinding: Before design, we analyze your barite ore for BaSO₄ content, specific gravity, and associated minerals (quartz, calcite, sulfides). A pilot grinding test determines the optimal mill type and produces a 10 kg sample with guaranteed density and particle size.
· API Performance Test & Handover: A 72-hour continuous performance test verifies plant output, product density, 200-mesh passing rate, and specific power consumption. The plant is handed over only after meeting all contractual guarantees.
· After-Sales & Wear Parts: 12-month defect liability period. High-Mn liners, classifier rotors, and grinding media are stocked regionally. Training for operators and lab technicians included.
