Product Description

Introducing the Metallurgical Dolomite Rotary Kiln Production Line, offering a versatile range of 100-600tpd capacity.

Product Introduction
The metallic magnesium production line is an exquisitely designed rotary kiln, carefully tailored to meet the specific calcining characteristics of dolomite while adhering stringently to the demands of the renowned Pidgeon method for magnesium smelting. This kiln is the cornerstone of the dolomite calcining system, ensuring superior efficiency and precision in production. products crafted by this cutting-edge rotary kiln exhibit remarkable stability and uniform quality, featuring high reactivity and minimal loss on ignition. It adeptly meets the stringent criteria of the Pidgeon method for magnesium smelting, enhancing magnesium extraction rates and optimizing silicon usage, thus markedly reducing production expenses and lowering metallic magnesium consumption,. This is the essential equipment for dolomite calcination, pivotal in the magnesium manufacturing domain.
The comprehensive magnesium smelting processunfolds through a sequence of precise stages: starting with raw material storage, advancing through dolomite calcination, grinding, and briquetting, and culminating in reduction and refining. Initially, raw dolomite is crushed to optimal dimensions (20-40mm) using a crusher, then sintered in a rotary kiln, followed by cooling in a cooler, and finely milled by a ball mill. This powder is then formed into balls using a ball press. The calcined dolomite is evenly mixed with ferrosilicon and fluorite powders to create a cohesive mixture, placed into heat-resistant stainless steel reduction tanks. In the reduction furnace, the temperature escalates to 1200-1250°C under a vacuum of 1.33Pa, facilitating the extraction of crude magnesium, which is then refined, cast into ingots, and undergoes surface treatment to produce finished magnesium ingots.

Product Advantages
1) Fuel combustion equipment: Features cutting-edge energy-efficient burners that automatically regulate air distribution, and optimize thermal efficiency.
2) A vertical preheater at the rotary kiln's end efficiently leverages the high-temperature flue gas from the kiln's combustion to preheat materials,. This revolutionary strategy allows the materials to begin partial decomposition within the preheater,, thereby significantlyamplifying system output and improving thermal efficiency.
3) A vertical cooler at the kiln's forefront fully utilizes the heat from the kiln's high-temperature whitened material to preheat the secondary air to a remarkable 650°C, further boosting thermal efficiency and ensuring exceptional economic returns.
