MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202511126316 A) filed by Raghav Productivity Solutions Private Limited, Jaipur, Rajasthan, on Dec. 13, 2025, for 'a system for the automated production of ramming mass from quartzite boulders.'
Inventor(s) include Sanjay Kabra.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "A system for the automated production of ramming mass from quartzite boulders The invention provides an automated integrated plant and method for producing high-quality ramming mass from quartzite boulders sized 125-500 mm, for furnace lining applications. The system comprises a feed hopper for regulated material flow, a primary jaw crusher reducing boulders to 100 mm or smaller, two alternately operating secondary jaw crushers producing 2-35 mm particles, and screening vibrators separating fractions into less than 7 mm (for direct use) and 7-35 mm (stored in a silo). Two vertical shaft impact crushers further reduce particles to 7 mm or smaller, followed by a magnetic separator to remove iron contaminants. Material is buffered in a second silo, then segregated into size fractions (7-6 mm, 5 mm, 4 mm, 2.8 mm, 2+1 mm, 0.7 mm) via a step belt conveyor and vibrators, and stored in dedicated silos. A ball mill grinds selected grains into 200 mesh fines, separated by an air separator and stored in two fines silos. A PLC-controlled weighing system and binder dispenser precisely feed grains, fines, and binders (boric acid or boron oxide) into intensive mixers for homogeneous blending. The final ramming mass is packed into lined gunny bags, sealed, and dispatched with tarpaulin protection. The method ensures efficient production with recirculation for uniformity, minimal human intervention, and high purity."
