Micro powder roller mill is also known as ultra-fine powder grinding mill. It is a new type of powder processing equipment, mainly used for crushing and processing non-metallic minerals such as calcium carbonate, barite, talc, gypsum, calcite, limestone, calcium oxide, bentonite, dolomite and other non-metallic minerals with Mohs hardness less than 5 and water content less than 5%. Generally speaking, its feeding size is 0 to 10 mm and the discharging size is about 5 to 45 microns.

Once the micro powder roller mill appeared in the market, it has been welcomed by the majority of customers. After the practice of the majority of customers proved that the equipment has the advantages of superior performance, stable quality, simple operation and easy maintenance, which is the ideal equipment for ultra-fine micro powder processing.
For micro powder grinding mill and ball mill, they are both equipment that can grind fine powder. Some customers who do not know much about these two equipments may not quite know how to make a suitable choice. In the following, I will briefly introduce the differences about these two kinds of equipment in order to help you choose a more suitable grinding equipment.
The micro powder grinder mill production line is generally composed of jaw crusher, bucket elevator, hammer crusher, storage bin, main machine, cyclone dust collector, pulse dust collector, air blower and other parts.
Among them, the main machine is mainly composed of base, central shaft, turntable, grinding roller, grinding ring, lubrication device, classifier, belt drive, shock absorber, main motor and other parts.
After the large size of materials are crushed by the crusher to meet the feeding size of the micro powder grinding machine, they are sent to the storage bin by the elevator. Then it passes through the vibrating feeder and delivers the materials evenly to the main machine.
The material is scattered to the periphery by centrifugal force and falls into the grinding chamber, where it is rolled and ground by the grinding roller in the ring channel of the grinding ring. After repeated grinding by three or four layers of ring channels, the powder is finally formed.
Then, the unqualified coarse powder is returned to the grinding chamber for regrinding, and the qualified fine powder enters the cyclone dust collector with the airflow. The fine powder falls down and is discharged by the discharge valve at the bottom. That is the finished product.
There is a small part of the fine powder with the airflow into the dust collector, adhering to the surface of the filter bag. The dust adhering to it will fall due to the sudden shaking of the filter bag. The conveyor at the bottom sends out the fine dust collected in two places for packaging of finished products. The clean air after filtering is finally discharged at the muffler outlet.
1.High output. When crushing calcium carbonate, and if the fineness requirement is D97, 10 microns, the output can be more than 1 ton per hour.
2.Built-in classification system. The fineness of the finished product can be adjusted at will between 5 and 45 microns.
3.Environmental protection and pollution-free. The dust collection efficiency of the whole set of equipment is as high as 99.9%, with stable operation and no dust leakage problem. In addition, the main machine and the fan are each installed with muffler room and silencer to reduce the production noise, which is in full compliance with environmental protection standards.
4.The control cabinet is installed with automatic control system to avoid the influence of human factors and to ensure the stability of product quality as well as to extend the service life of the equipment.
5.Our micro powder mill has been very mature and stable, with simple structure and easy operation. The complete set of equipment is easy to install and can be put into production after installation. Moreover, the equipment supports 24-hour all-day production.
6.The grinding rollers, grinding rings, roller pins and other accessories have a long service life and have a one-year warranty. Especially, the wear parts for grinding will not break or deform under normal use and long-term operation, except for normal wear and tear.
7.We have a professional quality inspection and testing department to strictly control the whole production line, thus ensuring the quality of the equipment when it leaves the factory.
There are many micro powder grinding mill manufacturers in the market. Maybe some customers would like to know, what are the advantages of your micro powder roller mill compared with other manufacturers'? Why should we choose Daswell Machinery as our supplier?
First of all, our engineers have an average of more than thirty years of experience in this industry. No matter for the degree of understanding of the equipment or for the configuration of the whole production line, they are very professional. Whether customers need to configure crushing equipment before grinding or add coating machine after grinding, they can provide better technical support for customers.
Secondly, the performance of our super powder roller mill is more stable, and the maintenance cost at the later stage is relatively low. For example, our grinding rings, grinding rollers, roller pins and other wear-resistant parts are all independently developed and cast by our company, which have a long service life.
Under normal circumstances they can be used for 3-5 years, while the wear parts of other companies need to be replaced in half a year to a year. Using our grinding mill can greatly save the time needed to replace the wear parts, and also save the maintenance cost. Using our mills for four to five years can save the investment cost of a set of production line.
Finally, when customers buy micro powder roller mill, one of the more concerned issues is its price. Our Daswell can provide a favorable and reasonable quotation for our customers. Because we have our own production factory, so there is no middleman in the whole transaction process. The factory sells directly, which saves the cost of middlemen.
When you find several manufacturers online and ask for a quote at the same time, you may find that some of them will offer you a very low quote, probably because the quality of their products and the related services they can provide are not guaranteed.
If you have any questions about our products, please feel free to get in touch with us and we will reply to you as soon as possible!
