China Fotes ceramic ball mill can do both dry and wet grinding and can choose different lining boards to meet various demands according to different production requirements.

The grinding ceramic ball mill uses different ball mill ceramic liner types according to production needs to meet different needs. The finess of ceramic ball mills depend on the grinding time. The electro-hydraulic machine is auto-coupled and decompressed to reduce the starting current. Its structure is divided into integral and independent.

The grinding fineness depends on the milling time. The motor of the ceramic ball mill is started by the coupling reduce voltage which lowers the starting electricity and the ball mills structure is divided into integral type and freestanding type; advantages of the ceramic ball mill are lower investment, energy saving, structure novelty, simply operated, used safely, ability even, etc.The ceramic ball mill is suitable for mixing and milling of the general and special material. Users could choose the proper type and line, media material depending on material ratio, rigidity, and output size, etc.

Ceramic ball mill is the typical grinding equipment which us ball mill ceramics, greatly improves the grinding fineness. Compared with the traditional ball mill, such kind of ball mill has a great advantage in function, structure, and operation. This machine also has great capacity, high technology, and no noise, which plays an important role in the field of Metallurgy, building materials, chemicals, industry.

The small tonnage glaze ball mill is the main machine used to make glaze ceramic grinding balls by the industries of producing household porcelain, electrical porcelain and building porcelain. It is applied to grind different glaze materials with different colors and has features of good grinding quality, compact structure, little noise, and simple maintenance.

The ceramic ball mill is a wet type grinding machine for the ceramic materials which can realize high efficiency for fine grinding of the medium crushed materials. Then, how to ball mill ceramic powder? Once users add raw materials, water, and ceramic grinding media in a proper proportion into the cylinder of the ball mill, they will get the ideal product particles by adjusting the required grinding period.

The fine material slurry is especially suitable to be applied in the industries of large-sized household porcelain, electrical porcelain, building porcelain and chemical engineering. And thats the main reason why the producers love ceramic glaze ball mill so much.According to the different demands, the ceramic grinding ball millcan produce different range of the partical ship.

This is a 3-foot by 6-foot continuous ball mill, and this machine will process one ton an hour at 65 mesh. You can actually process finer than that, down to about 200 mesh, but the throughput goes down. To the feed side, you can put three quarter to one inch minus here. then, ore enters into the scoop of ball mill, with a two-ton charge of balls. The material works its way through the ball mill, which turns about 35 RPM, with the water addition. To the discharge, they will go on to the shaker tables for concentration.

Here are three different size balls we use. And you add equal amounts of each size ball when you charge the mill. And then as the balls wear, you keep putting in larger balls. Again, it is about a two ton charge of balls. The machine empty weighs about 8,500 pounds, with the charge of balls, it weights about 12,500 pounds.

lets look inside the ball mill now, you can see it has cast armor lining the inside of mill. This is the feed side, and across the mill, here is the discharge side, and it has a grate to keep the balls in. There is an augur in there that screws the material back in, so only the finest material can exit the mill.

The mill weighs a little more than 3 tons, and you can easily turn the mill with one hand. So, its a really smooth mill, not a lot of friction. It runs with a 25 horse, 3-phase motor. And here in a couple weeks, well be getting this mill up and running and put a lot of balls in and run some material.

First. Installing the main bearing. In order to avoid the aggravating the wear of shoulder and bearing lining of the hollow journal, the gap between the base plate of two main ceramic ball mill bearings is no more than 0.25mm.

Second. Install the barrel of ceramic ball mill. According to the specific conditions, the pre-assembled whole simplified parts can be directly installed or installed in several parts. Check and adjust the center line of the journal and ceramic ball mill.

Third. Install transmission parts such as pinion gears, couplings, reducers, motors, etc. In the process of installation, measurements and adjustments should be made according to product technical standards. Check the radial slip off the ring gear and the meshing performance of the pinion, concentricity of reducer and pinion, and the concentricity of motor and reducer. Until all installations are ready, the foundation bolts and the main bearing bottom plate can be watered.

ceramic end mill achieves long life and high mrr at standard machining center speeds | modern machine shop

Material advances have produced a ceramic end mill that performs well at lower cutting speeds and competes with carbide in a broad range of applications. Your shop might begin using ceramic tools. #titaniummachining

Ceramic cutting tools offer a model case for appreciating the distinction between hardness and toughness. These very hard tools have long been a solution for machining very hard metals such as aerospace alloys. However, turning has been their principal application, because of a relative lack of toughness. The tools stand up to consistent high forces such as the steady cut in uninterrupted turning thank you, hardness but they are vulnerable to the bang-bang-bang shocks of an interrupted process such as milling, because enduring shocks is what toughness is all about.

Like other ceramics, this tool cuts dry and likes high cutting speeds. The crucial difference: The new phase-toughened solid-body tool performs well at cutting speeds that are low for ceramics, coupled with feed rate that is relatively high. The result is a solid ceramic round tool well suited to the capabilities of standard machining centers. All photos courtesy of Greenleaf.

Now, ceramic cutting tool maker Greenleaf says innovations in the toughness of ceramics within the last five years offer the potential to dramatically expand the applicability of ceramic tools in milling. The company recently launched its Xsytin 360 line of solid-body four-flute ceramic end mills, after two years of development. According to James Greenleaf, the third-generation owner of the company, these tools are the most extensively tested product we have ever introduced. And that testing continues, because a ceramic tool with greater toughness is a tool that potentially has promise within machining sectors and applications not typically associated with ceramics, involving shops that have not turned to ceramic tooling before.

drove Greenleafs first big breakthrough with ceramic tools, decades ago. The company introduced ceramic tooling in 1973, manufactured thanks to hot pressing technology that was proprietary at the time. But in 1985, the company proved and went to market with its method for adding reinforcing crystals grown in long, thin strands known as whisker reinforcement within the microstructure of the hard turning tools made this way

(Memory lane: My first job in industry was in a machining laboratory where we evaluated cutting tool performance in aerospace alloys. I spent a lot of time looking at WG300 inserts cutting edges under a microscope.)

Four-flute ceramic end mills are available in cutting diameters from 3/8 to 3/4 inch. Stability is a requirement for using the tools well. The flute design for minimizing vibration is thus an important part of the engineering.

The company also applied ceramic inserts to milling, albeit on larger-diameter tools. But now, the latest major advance in ceramic toughness has led the company to introduce smaller-diameter solid tools as well as inserted ballnose tools. This latest toughness advance is not because of the addition of a different reinforcing mechanism, but rather because of a proprietary phase toughening process that leads to greater control over the formation of the ceramic material, including the formation of the whiskers. As the company explains, phase toughening of the material delivers a stronger material substrate as well as more predictive performance in applications where other cutting tool ceramics are prone to failure. The material made this way still favors hardness over toughness, but now within a combination that not only provides for the requirements of smaller-diameter tools, but also lands nearer to the needs of general machining and to the performance capabilities of more mainstream machining centers.

The Xsytin 360s SiAlON (a ceramic combining silicon, aluminum, oxygen and nitrogen) is a material about which James Greenleaf feels he can confidently say, This is the strongest ceramic material on the market. We finally felt we had a ceramic good enough to offer a really effective round tool.

In test cutting, the performance and promise of the new round tools have been seen not principally in the high speeds these tools are able to achieve, but instead stay with me on this important improvement has been found at the low speeds at which these tools cut well. Ceramic tools are generally run at very high speeds (and run dry) because the ceramics thermal coefficient makes the tools so heat-resistant. The tools even haveminimum cutting speed thresholds for optimal performance. However, the new,tougher ceramic tools do not need theintensity typical of ceramics. The optimal speed range for the new solid ceramic end mills begin at 1,300 sfm, low compared to other ceramic cutters. For a 1/2-inch end mill, that is about 10,000 rpm. In short, the needed speed is accessible to a broad range of machine tools used by a broad range of shops.

Compared to carbide end mills, the ceramic tool can realize both a much higher cutting speed and a much higher feed rate for a higher metal removal rate overall. Shown here are parameters for machining Inconel 718. Note the ceramic tools speed, which, while high, translates to only about 12,000 rpm.

Yet even at a lower speed than is typical of a ceramic milling tool, the company says its testing in materials such as the aerospace alloy Inconel 718 still shows better metal removal rates and tool life than existing ceramic round tooling. This, too, is because of the freedom of toughness. The lower speed can be matched to a feed rate about 3.5 times that of what existing ceramic end mills accommodate. The result is an inch-per-tooth (chip load) feed rate equivalent to that at which the shop might be accustomed to programming carbide, yet at a much higher spindle speed than would be appropriate for a carbide tool.

Hardness and toughness together mean slow progress of tool wear. The edges of the 1/2-inch diameter ceramic end mill here show the wear after 72 minutes of milling for 64 cubic inches of material removal in 4150 steel with hardness of 52-55 HRC.

Against carbide, the company reports productivity improvement on the order of a factor of 10 in milling hard steel, aerospace heat-resistant superalloys, compacted graphite iron and various hard alloys that are now finding use in production parts made through additive manufacturing processes such as laser powder bed fusion.

That productivity improvement does need the right setup. The Xsytin 360 milling tools making use of the phase-toughened ceramic are not a replacement for carbide; we have been speaking of toughness, and carbide is still the tougher material. The ceramic end mills capable of lower speeds still need effective process controls against shocks to the tool controls that include rigid fixturing; short overhang in the tool setup; a shrink-fit, press-fitor hydraulic toolholder for low runout; and a tool path ensuring continuous cutting by maintaining a consistent chip thickness. Indeed, the tools flute design is part of this formula and another important part of the engineering of the tool. This flute aids stability through a geometry that has been refined to minimize vibration. Also needed in the application of the tool: a way to clear chips from the path of the cut without coolant, because this ceramic, like earlier ceramic tools, does far better running dry.

However, within the many shops able to achieve this level of stability and control, this tool is now a competitor to carbide in a way that ceramic round tools have not been before. The level of toughness resulting from the phase toughening has brought us to this point of change: In facing their challenges with hard metals, many shops will now consider ceramic milling tools that have never used tooling made of this material before.

4150 steel machining in action. The workpiece here is hardened to 54 HRC. The solid-body ceramic milling tool is 0.75 inch diameter. Cutting speed is 1,500 sfm. Feed rate is 0.001 ipt for a full-diameter slotting pass at 0.125 inch axial depth of cut, and 0.0024 ipt for a profiling passes at 0.125 inch axial depth of cut and 0.060 inch radial depth of cut.
