1.Ball mill: the grinding medium is mainly short steel bar or steel ball.The grinding force of ball mill is large, the structure is light, and the rotation speed is stable.
The above is the main content of thisarticle.The ball mill and the rod mill are the same type of machine on the appearance,but there are still great differences in the interior.It is very necessary toselect a suitable machine for the production to optimize the product effect andmaximize its efficiency.
Grinding media are available in agate, sintered corundum, tungsten carbide, tempered chrome steel, stainless steel, zirconium oxide, and polyamide plastic.The exact type of bowl and balls that are used depend on the type of material being ground.For example, very hard samples might require tungsten carbide balls in steel bowls.For typical use, agate is a good choice.As with any method of grinding, cross contamination of the sample with the grinding unit material can be a complication.While ball mills save considerable time and effort over hand grinding with a mortar and pestle, this is not without cost.List prices for the simplest jar mills are in the ballpark of $3,000 usd, and 4-station mills like the one shown above can cost $10,000 or more.Grinding bowls with lids can be $1,000 to $2,000 each depending on the size and the material required.Balls can add from $25 to $400 per bowl depending on your material needs.
As the development of reforming and opening, our beneficiation technology has undergone enormous changes, which has gone beyond the international level in the technology and quality.Commonly used ore beneficiation equipments include: crusher, ball mill, screening & classification equipment, magnetic separator, flotation machine, dryer, etc.The development of ore beatification equipment and technology is synchronization, the process is dominant, the device is the foundation.Hongxing ore dressing process include magnetic separation process, flotation process, lead and zinc mineral process, etc.Each process has different operating processes depending on the raw materials.Impact crusher(impact breaker) is a new type of high-efficiency crushing equipment.Its features are small in size, simple in structure, big reduction ratio, low energy, large production capacity, equal product granularity, selective in crushing minerals.It is a promising equipment.
Because the dust of quartz sand is extremely fine, if the human body inhales the dust containing quartz sand for a long time, it may suffer from silicosis.Therefore, the new quartz sand ball mill developed by jxsc uses a fully enclosed structure, which effectively avoids the harm caused by flying dust to humans and improves the working environment.
Its main component is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery.Materials are put in cylinder through the feed opening and then thoroughly grinded.The falling course of iron balls and ores can produce huge falling impact and autogenous grinding.The continuous feeding of ores can create considerable pressure to make ores move from feed opening toward discharge opening.Finally, acceptable particles are discharged from the discharge opening.Acceptable ore particles are carried away by water by wet mill, or by air by dry mill.The hollow shaft comprises reciprocal screw impellers that can carry overflowed iron balls and coarse ores back to mill.Energy-saving overflow ball mill has simple structure and higher operation rate.Equipped with rolling bearings, it can considerably save energy.
1.Short-cylinder ball mill: the length (l) of the cylinder is less than twice the diameter (d) of the cylinder, that is, the ball mill with l 2d is a short-cylinder ball mill.Single-bin structure ball mill, which is mainly used for coarse grinding or primary grinding, has high efficiency.
Pennecon successfully completed the install and commissioning of a ball mill for iocs cep2 expansion project.At 900 tonnes, 13.8m long and 6.6m wide, its one of the largest ball mills in north america.The ball mill, which was previously set to be installed in sept-les, quebec, was shipped via rail to labrador city.Over 50 train car loads of parts, material, and equipment that had been in storage for more than 10 years were unloaded to complete this project.
The end cover and the hollow shaft can be made into an integral or split type according to the actual situation of the project.No matter the integral or split type structure, the end cover and the hollow shaft are all made of casting after rough machining, the key parts are detected by ultrasonic, and after finishing, the surface is detected by magnetic particle.The surface of the hollow shaft journal is polished after machining.The end cover and the cylinder body are all connected by high-strength bolts.Strict process measures to control the machining accuracy of the joint surface stop, to ensure reliable connection and the concentricity of the two end journal after final assembly.According to the actual situation of the project, the cylinder can be made as a whole or divided, with a flanged connection and stop positioning.All welds are penetration welds, and all welds are inspected by ultrasonic nondestructive testing after welding, the whole shell is returned to the furnace for tempering stress relief treatment, and after heat treatment, the shell surface is shot-peened.The lining plate of the ball mill is usually made of alloy material.
With its high quality products such as china cone crusher, vibratory feeder, rock crusher, ball mill, rotary kiln, henan hongxing mining machinery co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
Ball mills typically are loaded with iron, steel or ceramic balls, or combinations thereof, about the size of a baseball.The balls rotate within the housing of the mill, macerating/pulverizing the contents to a desired particle size.During this process the balls gradually wear down in size, and must be replaced on a continual basis in order to maintain efficiency.Heretofore feeding of the balls has been a manual job, which is both difficult and dangerous.
