ZTM125 Straight Centrifugal Grinding Mill adopts rolling and grinding principle and scientific structural design, introducing several technologies of pre-grinding. Compared with the traditional grinding Mills, ZTM125 STRAIGHT CENTRIFUGAL GRINDING MILL has its own superiorities: high-efficiency, energy-saving and environmental protection.

ZTM125 STRAIGHT CENTRIFUGAL GRINDING MILL adopts repeatedly grinding the material with medium speed and medium pressure. The material with high hardness degree can be grinded on account of the reasonable design of this machine. The upper, central and lower parts of the grinding rollers and rings are worn out in the same level. And this Mill does not need other cyclone separator and piping system.
After being grinded by ZTM125 Straight Centrifugal Grinding Mill, the physical characteristics of the material are changed and their grindablity is improved greatly. The grinded materials will be irregular multiple-prism, whose inner crystal lattices are already broken, the structure is loose, and the final sizes all have fissures. Thus, when the materials are regrinded, the Mill is mainly doing grinding work, not crushing work, so the capacity of regrinding is improved greatly.
The crushing ratio of the final products of ZTM125 Straight Centrifugal Grinding Mill is large and the fine products are in large proportion to the powder. When the massive materials come into ZTM125 Straight Centrifugal Grinding Mill, the materials are grinded into the powder through embossed tooth between the roller and plate, they are grinded into fineness size by rolling crush, and then they fall down into space between roller and plate, which forms a material bed, under the pressure of the spring device, many times extrusion on the material bed are done by the rollers, and the material to be the fine powder. Besides a large quantity of the fine powder are produced, which is finer than 100 meshes, many lump materials are grinded and yielding the fissure. The max size of the lump material will not exceed 3mm, easy to be regrinding.
The traditional grinding mills which depend on the high speed rotation to crush the materials. The wearing parts are easy to be worn out, and have the short service life. While for the ZTM125 Straight Centrifugal Grinding Mill, the grinding to the material is done by the material bed. The rotation and the revolution of the rollers avoid the direct collision of the rollers and gasket. Thus the service life of the wearing parts is extended, and also that will decrease the contamination to the powder.
ZTM125 Straight Centrifugal Grinding Mill has its own superiorities: good mechanical property, easy to operate, convenient to maintain, lower consumption, lower cost, dry or wet process, reasonable design, simple structure, easy to install, room-saving, lower noise and little dust with good environmental protection.
The Straight Centrifugal Grinding mills have already tackled the problems in grinding too hard material. For many years’ efforts, our experts did a lot to develop this high-efficient energy-saving grinding Mills. This machine adopts the new grinding principle, and it has reasonable structural design, adopts the wearable alloy, and introduces the superiorities of other grinding Mills. It is good for grinding the materials with the high hardness degree. Both dry process and wet process are available. The superiorities of the machine are: long durability of the wearable parts, low dust emission, simple structure, good performance, convenient maintenance.
Application：
This machine is of high-efficiency and low-consumption, and is widely used in electric power, metallurgy, chemical, steel, coal industry, and etc. It can grind the lump material into tough powder (the mixer of the fine powder, fine sand and tough sand), such as cement (raw or processed), quartz, feldspar, calcite, gypsum, limestone, dolomite, graphite, coal, coal ash ,talcum, granite, marble, barite, porcelain, some other materials that Moh's hardness is below 9.5.
Working Principle:
The decelerator installed on the upper part of the mainframe connects with the central axis through shaft coupling to rotate, and central axis brings the roller hanger to drive, and rollers on the hanger roll around the inner ring. The materials enter into the mainframe from the upper side of feeding hopper, and fall down onto the bulk tray, which rotates with the central axis, in two ways. Then the materials will be sent into the circling passage between rollers and rings evenly. After being grinded into pieces, the materials will be discharged from the discharge opening.
