The manufacture of steel, the world’s most commonly used material, is impossible without quicklime. Our calcium oxide, in the form of lump lime with grain size up to 60 mm, is used to manufacture pig iron. Within the blast furnace, the quicklime ensures that undesired contaminants like manganese, silicic acid, phosphorus and even sulphur are removed from the pig iron and fixed in the slag.
Lime delivers major efficiency gains in agriculture and pond fish culture in a way that is safe for the environment. Lime are a vital mineral substance in livestock feed and for providing healthy nutrition ， it is also used in soil to ensure an optimal pH value.
Quicklime products neutralise exhaust gas emissions, waste water from production processes, sewage sludge, and untreated water destined for drinking water. They also eliminate pathogenic germs and odours and bind heavy metals. The products used are calcium oxide and calcium dihydrate reagents, which are tailored to the special conditions of our industrial and local authority customers.
Quicklime for road paving - blended products for the refinement of asphalt. For road surfacing, refined qualities of quicklime are used to slow down the ageing of asphalt. Through the chemical reaction with bitumen, the asphalt surface becomes more resistant to higher temperatures and is protected against embrittlement cracks and cracking due to moisture absorption.
Quicklime has been used for construction since ancient times. The binding property of quicklime means that structures can survive for thousands of years. The Egyptian pyramids and the Great Wall of China are just two examples of the historical use of quicklime. Indeed, we know that mankind started using lime mortar as far back in time as 14,000 years ago.
Quicklime products (burnt lime, calcium hydroxide) are used in the chemicals industry, for example for the production of calcium carbide, propylene oxide, sodium carbonate and glycerine. They are also used to produce lactates and lactic acids as raw materials for cosmetics, medicines and foodstuffs. Calcium lactate acts as a humectant and acidity regulator in foodstuffs, for example. Calcis products are also used to make gelatine and produce citric acid for the food industry. In the paper and glass manufacturing industries, our lime products regulate the pH value. They are used for the same purpose in aluminium smelting plants and precious metal refineries.
After the large pieces of material are crushed to the required particle size by the hammer crusher, the materials are evenly and quantitatively continuously sent to the main milling chamber through the vibrating feeder for grinding. The powder rises with the air flow of the fan and is classified by the classifier. The powder that meets the fineness enters the cyclone powder collector through the pipe with the air flow, is separated and collected, and is discharged through the star discharge valve to become the finished powder. The airflow is sucked into the centrifugal induced draft fan from the return duct at the upper end of the cyclone powder collector. Qualified finished powder is sent to the finished product Silo by the elevator.
The entire airflow system of this machine is a closed cycle and circulates under positive and negative pressure.
