YGM high pressure micro powder mill is referred to as micro powder mill or super fine grinding mill. The high pressure micro grinder is mainly used for the ultra-fine powder processing of more than 500 kinds of materials, such as feldspar, talc, barite, marble, limestone, carbon black and clay. The fineness is between 80 mesh (0.19mm) and 425 mesh (0.033mm), and the finest powder is 500 mesh ( 0.025mm).
High Pressure Spring, Strong Grinding Force Compared with YGM high pressure grinder, the grinding force of YGM high pressure ultrafine grinders roller to material is increased by 800-1200 kg under the function of high pressure spring. Big Input Size, High Output Fineness Big input size, average output size could be 6.5 um. Energy-efficient In the condition of same capacity and fineness, energy consumption is 1/3 of jet mills. Seal Grinding Eclipsed form multiple seal grinding device with perfect seal.
Inside the host of the high-pressure grinder, a 1000-1500 kg high pressure spring is fastened on the roller hanger. After starting work, the grinding roller revolves around the spindle, and under the action of high-pressure spring and centrifugal force, rollers close to the grinding ring. The rolling pressure is 1.2 times higher than Raymond mill under the same power condition, so the capacity is greatly increased. When the grinding material enters the chamber, it is shoveled by a spade and fed into the grinding roller and the grinding ring for rolling. The powder after rolling is brought into the analyzer with the circulating air of the blower. The qualified fine powder enters the cyclone collector with the air flow, and the large particles fall back to grinding. The recirculating air returns to the blower to repeat the above process and the remaining wind enters the bag filter to purify. When grinding roller and ring reach a certain wear, adjust the length of the high-pressure spring to maintain a constant grinding pressure between the roller and the ring, so as to ensure stable capacity and fineness.

In the grinding room of the high pressure grinding mill, the grinding roller hangs on the hanging bracket across the horizontal shaft, and the hanging bracket and the main shaft connects the scrape knife frame. The pressure spring is pressed to the grinding roller driven by the pulling force. With the horizontal shaft as the supporting point, the spring pressure compresses the grinding roller to the interior surface of the grinding ring. When the motor is driven by the transmission device, the scraper knife will rotate with the grinding roller at the same time. The analytical engine will drive the impellor to rotate through the motor and the powder fineness is determined by the rotating speed.

In the grinding chamber, the grinding roller assembly is suspended on the grinding roller hanger through the cross-arm shaft and the grinding roller hanger is fixedly coupled with the main shaft and the blade holder. The pressure spring is tightly pressed by the tension rod in the grinding roller bearing chamber. On the outer end of the cantilever, with the cross-arm shaft as the support point, the spring roller presses the grinding roller tightly on the inner surface of the grinding ring. When the motor rotates through the transmission device, the blade mounted on the blade holder rotates synchronously with the grinding roller, and the grinding roller rotates around itself while rolling on the inner surface of the grinding ring. The analyzer drives the analyzer impeller to rotate through the motor drive, and the speed adjustment of the analyzer determines the fineness.

HPGR have been used for many years and are emerging as an energy-efficient alternative to conventional and AG/SAG comminution circuits. One of the interesting features of HPGR is its capability to produce a particle size distribution with a greater than typical amount of fines, thus reducing the power requirement for the downstream ball mill. This makes the use of standard ball mill analyses based on the K80 inadequate, unless appropriate corrections are made. (This problem is shared by AG/SAG mill circuits.)
The most appropriate way to get around this data problem is to run the entire circuit at pilot-scale and analyze the data based on the overall power applied in kWh/t. This requires a fair quantity of sample, and the difficulties inherent to performing such a pilot plant make it difficult to come up with reliable conclusions.
The use of a small locked-cycle scale test, such as the Bond ball mill grindability test, was proposed as an alternative way to achieve the same objective in a more controlled manner, and more importantly, with a smaller sample.
SGS has developed a simple methodology that is based on the 0.25 m LABWAL HPGR from Polysius, which has a sample top size of 12.5 mm. Several HPGR tests are performed to assess the effect of operating pressure and moisture content on the performance of the HPGR and the power input to the unit is recorded.
The HPGR product, corresponding to the best condition, is submitted to the standard Bond ball mill grindability test. The Bond ball mill grindability test measures hardness as an index, regardless of the feed size, so it does not give credit for the additional fines. Therefore, the index itself is ignored in the analysis and the results are assessed in terms of throughput rate or specific energy requirement.
The total power for the HPGR system can be compared to that of a conventional circuit, based on the rod and ball mill work indices and the Third Theory of comminution. The power comparison can also be done against AG/SAG mills. This methodology has only been used to scope the potential energy savings of HPGR at small scales.
We conduct HPGR testing in combination with other bench-scale tests and circuit simulation. The use of different test procedures and design methodologies provides you with a bankable solution that is unmatched in its rigor. Contact us to optimize the comminution design for your orebody.
The F-series HPGR, developed by FLSmidth, incorporates a combination of engineered solutions and optimised components. Our design is derived from our years of maintaining these machines in the field and aimed at decreasing maintenance downtime, while placing special emphasis on the health and safety aspects of these operations.
Our HPGR is flexible enough to be highly suitable for both brownfield expansions and greenfield installations. The wide variety of ways our customers are already using the machine shows just how helpful the technology is.
Our HPGR is a perfect complementary tool to work in conjunction with, and even enhance the performance of traditional grinding mills and fixed-gap crushers. The HPGR exposes feed material to very high pressure for a short amount of time. The compression typically causes the rock to crack and cleave along the grain boundaries, weakening the rock structure and exposing the ore particles. This high pressure also creates a large amount of fines and causes the formation of microcracks in the larger particles, lowering the Bond work index of the ore and reducing the ball mill power required downstream.
The F-Series HPGR is ourfull size machine used in large mining projects throughout the world. Operation, maintenance and service personnel collaborated to create this modern HPGR design. With it, you get a reduced footprint, convenient and safe handling for heavy components and improved shipping.
We re-designed our legacy roll press to upgrade it and optimise it for mining duty, and the result is our S-Series HPGR. Though this series is meant for smaller projects, plants and retrofits, it is packed with plenty of the same features that are in our larger models. And the smaller size means that your machine can be shipped partially or fully assembled, resulting in a faster installation.
The lower section of our HPGR feed chute, which typically experiences the highest wear, is lined with FLSmidths patented FerroCer Impact Wear Panels. Our wear panels haveproven to greatly outperform conventional wear plates in this application where the feed ore is often large, very hard, and highly abrasive. These panels are easy and safe to install, while providing the longest possible wear life. Learn more about where else in your plant operation you can optimize your durability with FerroCer Impact Wear Panels.
The planetary reducers are shaft mounted to the rolls and are linked together via the torque sharing arm assembly. This saves you money because it eliminates the cost of additional foundation structure and hardware to bear the torque arm reaction forces.
This feature also allows the drive train to be captured and held in place during roll change-out using our (optional) drive retraction cradle, which further optimises the roll change-out time and makes the procedure safer.
Mounting the hydraulic cylinders to the frame with hinges allows maintenance personnel to safely access and inspect these components without getting inside the framework of the HPGR. For any maintenance that required removing the cylinders, overhead access is free and clear of the frame with the hinges in the outboard position. Dual-acting means that no special tools are required to separate the rolls to clear tramp metal. By simply reversing the oil flow, the hydraulic cylinders can be used to retract the rolls and allow the tramp to fall through, getting the machine back online quickly.
The HPGR has a skid mounted tank with a lubrication oil conditioning system that supplies clean filtered and temperature conditioned oil to the roll bearings. A constant flow of oil carries the contaminants and heat that are generated in operation away from the bearings to maximising uptime. The lubrication oil system instrumentation monitors and protects the system. In contrast, conventional grease lubricated units are messy, require frequent relubrication and must be water cooled.
We designed the hydraulic pumping system to the cylinders with advanced skew control (ASC) and use linear variable differential transducers (LVDTs) to monitor the system. As skewing starts to occur in the floating roll, the ASC system adjusts the press force applied to the hydraulic cylinders, keeping the roll assemblies as near parallel as possible during operation, while at the same time maintaining interparticle contact and grinding efficiency over the roll width.
There are two frame styles offered for industrial applications. The S-Series, which incorporates a traditional box frame design, has been optimised for smaller plants. The F-Series, using our express frame, accommodates the need to handle and operate larger and heavier components.
We designed and built our express frame for a faster and safer replacement of the roll surfaces. With the minerals processing industry trending towards larger equipment, we specifically developed the express frame to handle larger, heavier components in a safer and easier manner.
This new frame uses a tapered pin and bushing concept. Removal of the tapered bushing creates more clearance space for inserting and removing pins. A wedge jacking system takes the load off the pins for quick extraction and replacement.
