MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202511126318 A) filed by Raghav Productivity Solutions Private Limited, Jaipur, Rajasthan, on Dec. 13, 2025, for 'silo-level interlock system for a ramming-mass production plant.'
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: "Silo-Level Interlock System for a Ramming-Mass Production Plant A silo-level interlock system is disclosed for a ramming mass production plant comprising a plurality of grain silos storing quartzite grains in distinct size ranges (e.g., 0 to 1 mm, 1 to 2 mm, up to 7 to 12 mm, 0 to 4 mm, 0 to 5 mm, and 40 to 6 mm) and at least two fines silos storing 200 mesh quartzite fines from a ball mill and air separator, along with a PLC-controlled weighing and mixing system. The interlock system includes level sensors associated with each silo to generate material level signals and a PLC programmed to compare these signals against preset thresholds. Upon detecting a level below the threshold in any silo, the PLC executes an interlock disabling the weighing and mixing system, specifically halting screw conveyors at affected silos while permitting upstream operations (e.g., crushers, color sorters). Resumption requires refilling the silo to or above the threshold, ensuring proportional discharge of recipe components for homogeneous ramming mass blends. Thresholds are adjustable per recipe, with alerts identifying deficient silos. An override mechanism with manual confirmation and logging supports maintenance. Positioned downstream from magnetic separators and vibrating screeners, the system monitors the silos, enhancing product quality by preventing imbalances that could impair refractory performance in furnace linings. The method counterpart involves storing graded materials, generating level signals, comparing thresholds, executing interlocks, and requiring refills for quality assurance."
