Scorpio Engineering BMH designs, manufactures and installs pneumatic conveying and handling systems for limestone, lime, calcium carbonate, talc, gypsum and other industrial minerals: bulk tanker and bag unloading, silo storage, dense phase conveying of abrasive powders, and weighing and batching, from about 1 to 65 tonnes per hour.
More than 20 lime and limestone handling systems for steel, aluminium, water treatment, glass and global ingredient plants in India and abroad.

Most mineral plants follow the same path: the mineral is received in bulk or in bags, stored in silos, conveyed in dense phase to keep wear down, and dosed by weight to the process.

General arrangement of two dense phase limestone conveying systems for a refinery’s captive power plant: pressure vessels under the limestone transfer tanks (right), the pipeline along a trestle and up the transfer tower, and the discharge into the storage bunkers (left).
Refinery captive power plant
Scorpio supplied two dense phase systems, each rated at 56 TPH and designed for 65 TPH, that convey powdered limestone 300 m horizontally and 50 m up to six discharge points at the plant’s storage bunkers. Low conveying velocity keeps wear on the long pipeline and its 24 bends under control.
Large aluminium producer, Gujarat
Scorpio built a 12.5 TPH dense phase system conveying lime for an aluminium plant, moving the powder slowly in a closed pipeline to keep dust and pipe wear down.
Integrated steel plants
For steel plants, Scorpio supplied 6 TPH dilute phase systems conveying burnt lime from storage to the process, with the closed design that quicklime needs.
Global nutrition ingredients maker, Tamil Nadu
Scorpio supplied two dilute phase batching systems at 15 and 8 TPH that dose four minerals at four batches an hour, a 4 TPH vacuum system, and dense phase limestone conveying at 10 and 6 TPH.
Plastic packaging film maker, Karnataka
Calcium carbonate filler arrives in bags. Scorpio’s system slits and empties the bags dust-free, conveys the powder pneumatically to a storage silo and feeds it to the process.
Water treatment plants, India and Iran
Scorpio has built lime handling plants for water treatment, including twin 6 TPH systems in India and a 7 TPH lime plant for a water treatment works in Tehran.
Gypsum wall panel plant, Mumbai
For a gypsum wall panel project at a government fertiliser company, Scorpio designed and supplied the gypsum handling system feeding the panel line.
Advanced materials maker, UAE
Scorpio supplied a batching plant that conveys and weighs silica, magnesium oxide and calcium oxide for an advanced materials factory in Abu Dhabi.

Limestone and lime are abrasive. Dense phase conveying moves them slowly, as dense plugs at low velocity, so pipelines and bends wear far less and the material breaks down less than in a high-speed dilute phase line.
Yes. Quicklime reacts with moisture, so it is conveyed in a closed system with dry conveying air and sealed silos and hoppers. We have built dense and dilute phase quicklime and burnt lime systems for steel, aluminium and cement plants.
A bag slitting machine opens and empties the bags dust-free and separates the empty bags. The powder is then conveyed pneumatically to storage silos and fed to the process by rotary airlocks or screw feeders.
Yes. Each mineral is stored in its own silo and dosed into a weigh hopper on load cells under PLC control. One of our systems batches limestone, talc, china clay and fuller’s earth at four batches an hour.
Our mineral installations range from about 1 tonne per hour for a lime plant to two dense phase limestone systems each designed for 65 tonnes per hour, conveying 300 m horizontally and 50 m up.
Email marketing@scorpiobmh.com with the mineral, its particle size and bulk density, the capacity in tonnes per hour, conveying distances, and how it arrives (bags, big bags or bulk tankers). We reply with a system concept and budget.
Tell us the mineral and the rate. We design, manufacture, install and commission the complete system.
