We offer a full line of parts for rod, ball, and semiautogenous grinding mills for cement plants. Shell liners We offer many choices in design and alloys for all popular mills, ranging from traditional wave styles to step liners, classifying liners and SAG mill liners.
There are basically two groups of Grinding Mill Liners. Ones with a HIGH PROFILE and those with a LOW PROFILE. The high profile liner is designed to give the media the higher lift. This type will be used in mills that are designed for primary grinding and as a result require the impact of the higher cascade. Ball mills working as the secondary portion of a grinding circuit will utilize the
The grinding mill liners have certain degree of hardness to resist grind ball fatigue wear, cutting wear from edges and corners of the ore. 2. Classification . Mn13Cr2. High Chrome. Aluminum. Rubber . 3. Manufacturing process . Grinding mill liners are melted in electric furnace and poured into moulds after scientific
Figure 5. Highlow wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.
83 Centrifugal force outward Fc mpamp; 2 Dm 2 () amp; is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg () The particle will remain against the wall if these two forces are in balance ie.
Mineral ball mill. Ball mill, also called grinding mill, ball grinding mill, is the key equipment to grind the crushed materials, and the ball mill is widely used in powdermaking production line including cement, silicate, newtype building material, refractory material, fertilizer, ore dressing of ferrous metal and nonferrous metal, glass ceramics, etc, with medium hardness.
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about
ME Ultra Grind II #174; ME Ultra Grind We are the world leader in designing and supplying highly engineered grinding mill liners for SAG, AG, ball and rod milling. GENERAL DESCRIPTION. Our innovative liner designs and proven alloys maximize mill performance and availability while minimizing costly down time.
SAG and ball mills grind material through different actions and are usually applied in different stages of the process. SAG mills usually have a larger diameter than length and are used to reduce large feed size ore (typically ~300mm) down to ~3mm, often for further grinding in a secondary process.
about us. GAOTENG was founded in 2000, specialized in grinding media (such as:flint pebble, silex lining brick, alumina ball amp; alumina lining brick) for ceramic industry, cement, glass, quartz and zirconium silicate industry etc., exported to more than 30 countries and regions around the world, Southeast Asia, the Middleeast, Japan, America, Europe with over 140 customers.
Ball mill linings reduce noise levels for improved working conditions Our commitment to ongoing design improvements and high service offerings has resulted in the development of ball mill liners that extended periods between shut downs and improve grind efficiency.
The low alloy steel ball mill liners studied in this paper have high hardenability and high tempering stability. After quenching at 850930 and tempering at 200290, finely tempered lath martensite is obtained, which makes the steel have high strength, high toughness and high wear resistance.
The ball mill abrasion test (BMAT) promises to offer accurate prediction of relative service lives of wearresistant alloys for liners and grinding media in mineral grinding environments.
