Energy saving solutions in cement production
(Baonghean.vn) - Cement production is one of the most energy-consuming fields, so finding the most effective solution to save energy in production to cut costs and increase profits is always a matter of concern for businesses.
In cement factories, energy in general and electricity in particular accounts for a large proportion of production costs. Using electricity economically and efficiently helps reduce production costs, reduce product prices, and increase competitiveness in the market.
In Nghe An, Tan Thang Cement Factory (Quynh Luu) uses a system of equipment andtechnological chainFLSmith's synchronous line - Denmark is considered one of the most advanced lines today thanks to the application of new technological solutions for high productivity and energy saving.

The factory has a capacity of 5,000 tons of clinker/day, equivalent to 2 million tons of cement/year; After a trial period, the entire production line of the factory has now been put into stable operation. Since the beginning of the year, the enterprise has produced more than 500,000 tons of clinker, 261,000 tons of cement; the output consumed is more than 212,000 tons of clinker, more than 257,000 tons of cement.
Tan Thang Cement Factory has the latest generation of production technology from the world's leading manufacturers.cement production. It is a material crusher, coal crusher, 2-support clinker kiln using the most advanced technology and equipment of FLSmidth - Denmark; New generation vertical mill system.

In particular, the ABB (Switzerland) electrical automation system - the core of 4.0 technology - is at a high level, centrally controlled to synchronously control the factory's operations, connecting electronic, mechanical and environmental technologies together. This system only consumes a minimum of 90 kW/ton of cement, consumes less than 730 kcal/kg of clinker and is considered a low consumption level in the current cement industry.
Mr. Nguyen Xuan Hung - Head of Technology Department, Tan Thang Cement Company said: Advanced equipment technology plays an important role, but the decisive factor is the ability to manage and master the technology. With the same technology, the same equipment origin, the same capacity, but there are still factories that operate more efficiently, achieving greater profits than other factories.
In addition to limiting idling equipment, limiting high-capacity machinery from operating during peak hours, developing operating procedures, making detailed plans for equipment maintenance and repair..., we focus on training operating engineers, stable operating parameters, productivity... to meet the output of the furnace, so it does not operate during peak hours, ensuring maximum output.

Electricity accounts for a large part of industrial production, to reduce production costs, factories must apply all measures to save. Each enterprise needs to come up with a specific production plan, use machinery reasonably, apply labor efficiency to improve labor productivity, and limit wasteful use of electricity.

According to electrical engineers, the solutions to use electricity economically and effectively in factories basically include: Applying management solutions; Equipping an optimal energy management system; Using and replacing long-term, energy-consuming equipment with high-efficiency equipment, especially for electric motors and transformers; Energy-saving solutions for fan, pneumatic and pump systems. The more machinery is used, the more electricity is consumed, so businesses need to optimize production activities, limit delays and prolong time without high productivity.
