Introduction to Carbide Slag (calcium hydroxide) Drying and Calcination Process:
The carbide slag is the precipitate (industrial waste) generated from the hydrolysis of calcium carbide (CaC2) during the production of acetylene gas, polyvinyl chloride, polyvinyl alcohol and other industrial products, and its main ingredient is Ca (OH) 2. The carbide slag is one of the industrial wastes which are difficult to dispose. Liaoning Dongda Powder Engineering Technology Co., Ltd., engaging in the research and development of powder technology, drying, calcination and heat source equipment since 1990, focus on the integrated application of carbide slag and is committed to research the process and equipment and to develop the special equipment applicable to process in recent years. According to the market demand, our company presents the carbide slag-based dry-powder mortar gelling agent drying, calcination joint system equipment process, carbide slag drying system equipment and process to meet demand of market and customers.
Product Introduction:
It is a new carbide slag calcination process to produce calcium oxide via dynamic calcination process. Dry the carbine slag into powder, then enters into the dynamic calcination-decomposition furnace, the calcium oxide will be generated under the high temperature decomposition for a few seconds. The calcination is fast and the heat transfer is even, and there is no raw calcination and over-calcination in calcinated material, so the calcination temperature can be accurately and it is the advanced process to produce active calcium oxide. The system is mainly composed of preheating Si De dryer, Si De calcination-decomposition furnace, trap, heat source and so on.
Working Principle:
The material carbine slag is fed into dryer for drying via feeder, and take the residue hot air generated from the decomposition of carbine slag by calcination-decomposition furnace as the heat source for the drying, the dried carbine slag is fed into calciner for calcination, and the decomposed calcium oxide is discharged from the dumping port.
Performance Features:
1. Carbide Slag Drying and Milling Process System
The carbide slag applies the mechanical dewatering, and its water content is generally about 28 to 35%. The carbide slag is the waste slag with high humidity content and light mass, and its drying is difficult, so it needs to solve the following technical issues: to solve material feeding and block prevention; when falling into the dryer, it is apt to take place material stacking and adhesive block; after carbide slag drying, the dust concentration in the exhaust is high, so it is apt for dust collector to take place adhesive block and corrosion; when the carbide slag is drying, it needs to overcome the shortcoming of low evaporation rate and large moisture content. The application of Si De cyclone dryer, no-axis feeder and corrosion resistant materials can solve the above issues.
2. Carbide slag-based dry-powder mortar gelling agent drying, calcination joint process system
Calcination conditions: Direct fire heating via gas furnace
Temperature at calcination inlet: 1000 ° C ~ 1050 ° C

The calcination joint system equipment technology requires that, during calcination process, the material temperature should be maintained 900~1000° C, and the maintaining time is not less than 4 seconds.
Carbide slag initial water content: ≤ 20%
Water content after drying:1-2%
Drying temperature: 450 ° ~ 550 ° C
Carbide slag ingredient: calcium hydroxide 56~60%, calcium carbonate and calcium bicarbonate 5%, silicon and aluminum etc 35%
Designed product quality standards: Ca (OH) 2 content ≥ 85%
Water content: 1% ~1.5%
Particle Size: ≤ 50μm (270)
Specific surface area: 15 ~ 20m2 / g
