HGM Ultrafine Grinding Mill For Silicate Cement

The Guangdong Jiangmen Special Cement Project is a key project tailored by CLIRIK's HGM Ultrafine Grinding Mill for the infrastructure of the Guangdong-Hong Kong-Macao Greater Bay Area, focusing on the production of ultra-fine cement for tunnel construction.
The project adopts an intelligent production line with an annual output of 12,000 tons of special cement, filling the gap in the regional high-end cement market.

Core highlights:

• >> Equipment performance: HGM100 grinding mill processes 1.5 tons of silicate cement per hour, and the finished product fineness is 800-1200 mesh (5-18 microns), which fully meets the requirements of tunnel engineering
• >> Intelligent production: 15 automated control points, realizing the intelligentization of the entire process of "grinding-grading-collection"
• >> Energy saving and environmental protection: 33% energy saving compared with traditional equipment, saving 180,000 yuan in electricity bills per year

 

The technical upgrade process of a special cement project

1. Trial verification: 21 months of technical running-in

The cooperation of the Jiangmen project began in September 2021, when the customer team brought silicate cement raw materials to visit the Shanghai R&D Center of CLIRIK for a trial run. The result data showed that it far exceeded the customer's expectations of "1.2 tons per hour and power consumption less than 120kWh".

2. Field investigation: On-site verification of process layout

In April 2023, accompanied by the CLIRIK technical team, the customer visited the site of a HGM100 production line that had been put into production in Guangdong. The customer was deeply impressed by the degree of automation of the project. The customer's technical director said: "This layout mode of 'smart workshop' completely solves our concerns about the dirty and messy traditional grinding workshop." And emphasized the requirements in the subsequent design communication.

3. Decision-making acceleration: the plan was finalized in one month

With the trial data and field investigation results, the customer determined the equipment replacement plan in just one month. Compared with the original ball mill production line, the new solution has three core attractions: energy consumption is significantly reduced; labor costs are reduced; and the fineness of the powder is improved: from the original 500 mesh to 1000 mesh, which meets the quality requirements of the tunnel project.

4. Selection and configuration: the technical core of the HGM100 production line

The project adopts the HGM series 100 ultra-fine grinding production line independently developed by CLIRIK, which integrates "grinding-classification-collection" and realizes the added value empowerment from raw materials to ultra-fine powder through the deep integration of modular design and intelligent control.
 

Project advantages:

• >> Production increased by 130%
• >> The life of wear-resistant parts exceeds 1 year
• >> Bearing-free design eliminates downtime
• >> Adjustable fineness (200-2500 mesh)
• >> Intelligent frequency conversion control

1. High efficiency and low consumption

Under the condition that the finished product fineness is the same as the generator power, the HGM100 production line has a 130% higher output than air flow mills, stirred mills, ball mills, etc.; compared with traditional ball mills, the power consumption per ton of cement is reduced from 48kWh to 32kWh. Calculated based on an annual production capacity of 12,000 tons, the annual electricity bill can be saved by about 180,000 yuan. This advantage stems from the special design of the grinding roller, which significantly improves the energy utilization rate.

2. Long-term wear resistance

The grinding roller and grinding ring are forged with special wear-resistant materials. During the trial stage of the Guangdong Jiangmen project, after continuous operation, the wear of the grinding roller was less than 0.5mm. According to this calculation, it can be used for more than 1 year under normal working conditions, which is much higher than the replacement cycle of traditional grinding mills.

3. Safe and reliable

The "no bearing, no screw" design is adopted inside the grinding chamber to completely solve the shutdown problem of traditional grinding equipment caused by bearing wear and loose screws.

4. Controllable fineness

Different from the fineness limit of 325 mesh of Raymond mill, the HGM100 production line can be precisely adjusted within the range of 200-2500 mesh (74-5 microns).
In the Jiangmen project, in order to meet the requirements of "fine and uniform" cement particles for tunnel shotcrete, the finished product fineness is set at 1000 mesh (14 microns). The laser particle size analyzer detects that D90 (90% particle size) is less than 20 microns, which fully meets the requirements of the "Technical Specifications for Special Cement for Tunnel Engineering".

5. Intelligent frequency conversion

The production line is fully equipped with an intelligent frequency conversion system, which allows materials to be evenly fed and ground, and the main engine speed matches different materials. The finished product particle size is more stable and the particle size cutting accuracy is high, which improves the output and efficiency and thus reduces power consumption.

It took the customer only 21 months from trial to production, and the plan was finalized one month after the field investigation. The new equipment increased the cement fineness from 500 mesh to 1000 mesh, while reducing energy consumption and labor costs. This project has become a benchmark case for the upgrading of the building materials industry in South China.
