Product Description

Metallurgical Dolomite Rotary Kiln Production Line of 100-600tpd

Product Introduction
The metallic magnesium production line is an exquisitely engineered rotary kiln, crafted with meticulous attention to detail to cater to the unique calcining characteristics of dolomite and the rigorous process requirements of the distinguished Pidgeon method for magnesium smelting. This kiln is the cornerstone of the dolomite calcining system, offering unmatched efficiency and precision in operation. products produced by this cutting-edge rotary kiln exhibit remarkable stability and superior quality, boasting exceptional reactivity and minimal loss on ignition, effortlessly meeting the demanding standards of the Pidgeon method for magnesium smelting. This design not only optimizes the magnesium extraction rate but also enhances silicon utilization, significantly reducing production costs and conserving metallic magnesium,. It is an essential piece of equipment for dolomite calcination within the magnesium manufacturing industry.
The comprehensive magnesiumsmelting process unfolds through a sequence of precise stages: starting with raw material storage, progressing through dolomite calcination, grinding, and briquetting, and concluding with reduction and refining. Initially, raw dolomite is crushed to optimal dimensions (20-40mm) using a crusher, sintered in a rotary kiln, cooled in a cooler, and finely ground by a ball mill. This powder is then compressed into balls with a ball press. The calcined dolomite is uniformly blended with ferrosilicon and fluorite powders to form a cohesive dough, placed into heat-resistant stainless steel reduction tanks. Inside the reduction furnace, the temperature is elevated to 1200-1250°C under a vacuum of 1.33Pa, where crude magnesium is extracted, further refined, cast into ingots, and subjected to surface treatment, resulting in finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features advanced energy-saving burners that automatically regulate air distribution, and enhance thermal efficiency.
2) A vertical preheater at the rotary kiln's endpoint efficiently utilizes the high-temperature flue gas from the kiln's combustion to preheat materials,. This groundbreaking method enables the materials to begin partial decomposition within the preheater,, thereby dramaticallyboosting system throughput and improving thermal efficiency.
3) A vertical cooler at the kiln's forefront maximizes the heat from the kiln's high-temperature whitened material to preheat the secondary air to an impressive 650°C, further boosting thermal efficiency and guaranteeing exceptional economic returns.
