The equipment adopts high quality material, which has abrasion resistance, long service life, strong ability to adapt to the environment; it has open layout, which has high degree of automation, convenient operation, low noise, and the system works under negative pressure without pollution to the environment
Grinding Production Line is also called powder making plant, which is widely used for the powder making in mining, power, chemical industry, building materials, metallurgy, refractory materials, desulfurization of power plant, asphalt mixing station and highway industry, and the product size is adjustable in the range of 20 – 3250 meshes. ZK Machinery can not only provide powder grinding plant with wide selection ranges, reasonable matching, reliable quality and high performance price ratio for customers, but also offer the overall design and construction scheme of grinding operation as well as the turnkey project of the grinding field
It is often used for the grinding and processing of materials in metallurgical, building materials, chemical industry and mining industry, which is suitable for feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramic, bauxite, manganese ore, phosphate rock, red iron oxide, quartz sand, cement clinker, activated carbon, coal gangue, clay, gypsum, silicon carbide, refractory materials and other non flammable and explosive mineral powder materials with below level 8 Mohs hardness and less than 6% humidity
The Configuration of Powder Grinding Plant: Powder grinding plant is usually composed of jaw crusher, bucket elevator, electromagnetic vibrating feeder, grinding machine motor, analysis machine (powder separator), auxiliary equipment, blower, centralized electronic device. It also can be configured with micro powder mill, high pressure grinding mill, ultrafine mill, Raymond mill, tricyclic medium-speed micro powder mill or vertical mill according to the different needs of customers
The motor drives the reducer to rotate the millstone, the raw material are send into the center of the millstone from the air lock rotary feeder. Under the effect of centrifugal force, the material moves to the edge of the millstone. Material than be ground by the force of the roller and smashed under extrusion, grinding and cutting. At the same time, hot air is blew up around the millstone and bring up the ground material. The hot air will dry the floating material and blow the coarse material back to the millstone. The fine powder will be brought to the classifier, and then, the qualified fine powder will flow out the mill and be collected by dust collector, other coarse powder will be brought down to the millstone by the blade of classifier and be ground again. The circulation like this is the overall process of grinding.
With scientific & reasonable design and its unique advantages, HLM vertical roller mills are applied widely in power, metallurgical, cement, chemical and non-metallic industry, for grinding of various materials, such as cement raw material, clinker, limestone, slag, manganese, gypsum, coal, barite, calcite etc.. The grinding field is wide and grinding type is abundant
1. Humidity of grinding materials: from materials of 20-30% humidity(such as carbide, lignite, chalk, etc.) to materials of humidity less than 1% (such as cement clinker), wide range of materials. 2. Grindability of materials: from high grindability(such as quartz sand, steel slag, mining slag, pyrophyllite, iron ore etc.) to low grindability (such as gypsum, calcite, etc). 3. Fineness of grinding product: from 2-5mm(such as raw shale for making brich in new wall material industry, sand for construction industry, etc) Product fineness is easy to adjust and simple operation
HLM vertical Mill uses standard modules to design and fabricate pressurization device. With the increase in mill capacity, there is an increase in roller numbers (we can use 2,3 or 4 rollers, 6 rollers maximum) in proper permutation and combination to form the series of equipment of various capacities with minimum standard parts in order to meet the requirements of different materials, fineness and outputs
A cyclone filter is used for collection of product. This arrangement can help to reduce negative working pressure and air volnme of system. Both EP and bag filter can be used as final prodnct collector
The equipment features in a combination of crushing, drying, grinding, and conveying, simple process flow, reasonable and compact layout, space-saving (50% less than ball mill), lower foundation cost and workshop cost in the field;
The Line Grinder software generates isolation routing GCode from the Gerber format plot files output by most PCB design programs. However, Line Grinder is intended to be more than just a code generator. The GCode it produces, if run in the appropriate sequence, is intended to provide a method for reliably producing nicely aligned, double sided isolation routed PCBs including the cutting of border outlines and the drilling of pad holes and vias. It is intended to be both a GCode code generator and a methodology which will produce consistent results when cutting circuit boards.
The Line Grinder software is free and open source and is released under the MIT License. Be sure to read the license text before your use the software. Your use the Line Grinder software, and the output GCode it generates, is entirely at your own risk.
Please be aware that the Line Grinder software is purely a code generator. In other words, if you feed it some Gerber or Excellon files you will get some GCode out. Where, how and on what you run those GCode files is entirely up to you. Specifically, the Line Grinder software is not a machine controller (like EMC2, Mach3, TurboCNC or many others) and it cannot make your PC physically interact with a CNC mill. Once the GCode files are generated, your next step would be to open them in the machine controller software and run them there.
The Line Grinder software is provided in the form of a zipped archive. To install, simply download and unzip into a directory on your PC (C:\Program Files\Line Grinder is a typical choice). The Line Grinder software does not write to the registry and does not require any files to be located in any other directories. Configuration information is saved to an XML file named LineGrinder.xml located in the same directory as the LineGrinder.exe file. This file will be created automatically the first time the configuration of the Line Grinder software is saved.
As for system requirements, Windows XP (or higher) is needed and the Microsoft .NET 3.5 Framework runtime libraries must be installed on the installation PC. Most PC's have these libraries installed automatically. A reasonable amount of RAM, say 1GB or more should do the job nicely and the disk space requirements are nominal (less than 10Mb). The Line Grinder, when calculating isolation paths, is somewhat CPU intensive so a faster processor is better. Realistically anything 1 Ghz or better should be enough but you might have to wait a bit if your PCB boards have a large surface area.
