HGM125L ultrafine powder grinding mill is applied in the African market

Brief Introduction

In March, several sets of HGM125L ultrafine powder grinding mill developed by Shanghai SBM Micro powder Technology Co., Ltd. were successfully delivered to Uganda, Africa.

The engineer team of SBM is intensely and orderly completing the installation and commissioning, and it will be put into production soon.

SBM ultrafine powder grinding mill machines will fill the high-end milling needs of large domestic mining companies in Uganda for marble and granite mining areas.

Accelerate the realization of the plan of ” Expand production, diversify management, improve quality three steps “.

About Customer

In 2022, Uganda’s mining group learned about SBM Micropowder Technology Co., Ltd. through the international trading subsidiary of the domestic group, and conducted a lot of preparations and inspections in advance. In August of the same year, the person in charge of the group company: Mr. Sun Visited SBM Micropowder Technology Co., Ltd. with Manager Zhang and proposed to increase the demand for high-end powder product lines.

Through on-site communication with the technical team, after visiting the exhibition hall, comparing similar products of many similar mill manufacturers, combined with on-site test machine experience and test reports issued by our own samples, we recognized our products and summarized the following advantages:

1. The fineness of the finished powder is high, the content of 2 microns is controllable, and the powder shape is good.

2. The electronic numerical control operation mode is intelligent and the safety is greatly improved.

3. Small vibration and low noise when the equipment is running.

4. No dust spillage.

Ultimately, they chose to enter into a partnership with SBM.



This project plans to use mine waste to produce 325 mesh calcium carbonate powder. The 325 mesh calcium carbonate powder produced is used to produce putty powder, and produce finer calcium carbonate powder (325-1250 mesh) for the development of new markets in Africa.

SBM’s team of professional engineers takes into account its mineral resources of more than 33 square kilometers; before that, it mainly mined natural marble and granite blocks.

Combined with local construction conditions, infrastructure construction conditions, working condition permit resources, etc. to carry out personalized selection and configuration, and finally in our product line, choose the most suitable HGM series ultrafine grinding mil for the production of 150-2500 mesh fineness requirements.

And among the five models of 80, 90L, 100L-Ⅱ, 100P, 125L, and 1680L, after repeated research, the HGM125L ultrafine powder grinding mill with an output of 2.5-20 tons per hour was selected.

Product superiority

1. HGM125L ultrafine powder grinding mill under the same finished final size and the same motor power, the capacity of the superfine powder grinding mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.

2. HGM125L ultrafine powder grinding mill ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3 times longer than an impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate. The lifecycle of spare parts is variable for the material’s hardness.

3. As no rolling bearings or screws in the grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.

4. The final fineness of the grinding materials can be adjusted between 150 meshes and 3000 mesh (74-5 micron).

5. The application of pulse bag filters and mufflers greatly alleviates dust pollution and noise.

6. Let the material feed into the machine evenly, adjust the main speed to fit for ground material, the fineness more stable. To increase the capacity and efficiency, reduce the power consumption.
