chrome alloy ball mill liner High-chromium alloy cast iron generally refers to alloy white iron with chromium content of 8% to 26% and carbon content of 2.0% to 3.6%. Medium chromium alloy cast iron generally refers to chromium content of 4% to 6%.get price High energy ball milling process for nanomaterial synthesis

High chromium cast irons and high-speed steel type alloy are also widely used in steel plant, and Ni-Hard iron is generally used in finishing stands. The optimum composition of Ni-Cr white cast iron alloy depends on the mechanical properties required for the service conditions and the dimensions and weight of the casting.

Stainless steel is an iron alloy with added elements such as chromium, nickel, silicon, manganese, nitrogen and carbon. The properties of the final alloy can be fine-tuned by altering the amounts of the various elements.

Qiming Casting supplies Ni-hard iron steel mill liners for cement industry customers. This casting material is considered to be the ultimate developed and used to date for abrasion resistance in milling. It is commonly used in cement mills and some of the largest Ball Mills in the world and where performance has not been bettered to date.

Ball mill is a key equipment for grinding materials, widely used in powder-making production line such as cement, silicate sand, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. Ball mill can grind various ores and materials with the dry type or wet type.

Table 2 shows the typically used alloy types and material microstructures applied for various components in mineral ore processing stages. The equipment being most relevant to this consumption of casting components are ball mills (see Fig. 15). Approximately 55% of the material is used for breaker balls and 11% for liners.

There are three types of grinding media that can be used in ball mills of cement plants. 1. Steel Balls. Steel b alls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 120mm according to different grinding requirements. In a cement ball mill, generally, φ50–100mm steel balls are used ...

"In recent years, the trend to smaller top-size ore feed into SAG mills has been matched by a trend toward smaller but more balls in the SAG mill charge. High ball-to-rock ratios and low overall mill charge levels are now widely used. These practices can result in periodic loss of rock charge and ball-on-liner damage," said Royston.

A method of grinding a mineral-containing ore, which includes grinding the mineral-containing ore in a primary milling process and thereafter fine grinding the mineral-containing ore in a secondary ball-mill. A composite grinding medium comprising a mixture of steel balls and pebbles is used in the secondary ball-mill. The pebbles have an average size which is …

Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

Mechanical alloying is largely what it sounds like: creating a new alloy by mechanically forcing two or more metal powders together. The forcing is performed by the impact of media in a high energy ball mill. Depending on the metals, mechanical alloying can provide some challenges. One is that the alloy may adhere to the tank surface and media.

Cement Ball Mill Liner Alloy Steel Mill Liner's distinctive feature is to adopt multivariate alloy design. Alloy Steel Mill Liner Cement Ball Mill Liner increases carbide content in the medium carbon alloyed steel, through increasing the Cr & Mo content, the strong carbide forming elements, so as to improve its heat-resisting, wear-resisting ...

Grinding balls for mining are made from various metals such as steel, hard metal and ceramic. However, they are commonly manufactured from steel and steel alloys which have superior resistance to abrasion and low wear rates.
