Alumina balls for dry grinding,Energy-Saving Dry Grinding Medium

We are an integrated company with the ability to manufacture abrasion-proof material, make development and sales. Focusing on the production and application of grinding medium which is dedicatedly used for cement dry grinding machine, with nearly a thousand times tests and data gathering, we finally achieved the success of complete energy-saving technology improvement with consistent effort of R&D team in three years. Several national patents have been successfully certified. Many problems of cement industry also had been solved by us.

The Performance Advantages of Energy-Saving Dry Grinding Medium Are Specially Used for Cement

1) Low Energy Consumption: The density of energy-saving dry grinding medium that special used for cement is about 3.6 g/cm3 and density of high chromium steel ball is about 7.8 g/cm3; under the same volume, using energy-saving dry grinding medium that special used for cement is twice lower than using traditional grinding medium. Also, current of main engine gets lower along with temperature rise. Meanwhile, as its weight is light, effective loading rate of grinding machine can be moderately increased, which improves efficiency of powder grinding and output per hour. Then unit power consumption gets lower.

2) Low Temperature: Energy-saving dry ceramic grinding medium that special used for cement belongs to inorganic material. During grinding process, its heating value is very low. Without any static electricity, temperature gets lower and liquidity of cement increases.

3) Low Maintenance Costs: After using energy-saving dry grinding medium that special used for cement, temperature in grinding machine is low. In addition, as the weight of grinding machine is light and the entire impact force is little, comprehensive consumption of grinder in grinding machine decreases. Meanwhile, whole damage of equipment in grinding machine, including head of machine, and end of machine decreases. Therefore, maintenance period prolongs and maintenance cost reduces.[e1]

4) Improvement of The Distribution of Cement Particle: When producing ordinary cement by energy-saving dry grinding medium that special used for cement, inner grinding machine temperature is low and electrostatic effect of grinder is low. Then grinding efficiency is high; fineness and controllability of specific surface area could be further improved. As a result, shape of cement powder particles becomes better and quantity of 3-32 micron valid particle increase largely. Then early-stage and later-stage intensity of ordinary cement improved. Because grain shape tend to be better, water demand of ordinary cement and adaptability of admixture improve, which develop comprehensive quality of cement, reputation of product, and competitive force of market.

5) Improvement of Cement Adaptability: When producing ordinary cement by energy-saving dry grinding medium that special used for cement, inner grinding machine temperature is low and temperature of outcome cement is very low. This perfectly solves cement steadiness problem that caused by short interval from cement grinding to delivery. This effect shows obviously especially when grinding cement in high temperature seasons and grinding cement in concrete.

6) Environmental Protection: All sectors of the community and environmental protection department pay more and more attention to the damage of hexavalent chromium in cement. The government made a graft to limit water soluble chromium VI in cement on May.26th, 2013. In the process of traditional ordinary cement grinding, application of high chromium steel ball and lining plate is the main source of hexavalent chromium. Thus, there are few solutions can be taken. After adopting energy-saving dry grinding medium that special used for cement and ceramic lining plate technology, content of water soluble chromium VI in cement decrease largely as it prevents direct contact between high chromium metal and cement. Its significance of low carbon environmental protection wins support and promotion from all sectors of the community and environmental protection department.

We company holds the spirit of creating value for customer, studies the need from customer, provides different solution for customers, proceeds technology creation of various solution, and improves value and service for customers. At the same time, we welcome peer elites come to our company for investigation and reasoning.

Five advantages of Alumina dry grinding ball replaces the high chromium steel ball applying to the cement grinding.
