Nicest International Trading Co., Ltd. is a professional manufacturer of grinding media balls. Which has more than 19 years working experience in that field.
It has high hardness (HRC4555) and strength, which is better than ordinary round steel. The wear resistance is increased by at least 50%, which is extremely high. High cost performance makes our grinding rod widely used in major rod mills in China. SEE MORE.
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 sintering. It 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 its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls
Superior raw material, advanced automatic equipment, unique heat treatment technique and strict quality control system make better performance for the whole hardness of our hardness of our grinding steel ball, with surface hardness as high as 5865HRC, volume hardness es high 5664HRC, hardness distribute uniform, impact toughness bigger than 12J/cm2, and breakage rate much lower than %.
They are available in two grades1013% chrome (surface hardness 60 HRC, core hardness 58 HRC), and 1418% chrome (surface hardness 62 HRC, core hardness 60 HRC). They have a very rough black finish which quickly wears off during initial milling.
10/11/2020#0183;#32;Dry grinding method. Grinding material is a mixture of limestone (chalk, marble or other) in 75% and 25% clay. The size of the material is 1315mm. Grinding requirement: residue on a sieve (size of 80n) is not more than 7%. Since cement production material is sufficiently abrasive, it is necessary to use grinding balls with increased hardness.
26/12/2017#0183;#32;This would involve the media top selection size and the graded ball recharging as well. The principle applied here is that larger balls are suitable for coarse grinding while smaller balls are suited for fine grinding. This same principle is applied in ball mill cement grinding either with the use of division head, classifying liners or ox.
Ball Mills or Grinders are the effective tools for reducing the size of the balls based on the hardness, fibrous materials, or brittle. It is mainly enabled with a wide variety of grinding modes, grinding tool materials as well as usable volumes. The Ball Mill Grinder
According to the material, ranging from mm to 3 mm for small media mills, up to 3mm to 20mm for planetary ball mill, and up to 20mm to 50mm for ball mills: Grinding Ball Types: High precision ball, Semiprecision ball, sintered rough ball: Brand: Miller Precision Ball Classes: G5,G10,G25,G50,G100: Applications(Equipment)
As for the influence of hardness, generally speaking, as the hardness increases, as long as it does not break, the single consumption of the grinding media ball decreases, and the deformation of the ball body is reduced, the absorption deformation energy of the ball body is small in the process of crushing, and the energy can be used more for crushing mineral grains The productivity of the mill can be increased.
Metinvest offers grinding balls for ball mills with diameters from 30 to 120 mm of 14 hardness groups for the mining, coal, construction (cement manufacturing) and other industries. Steel balls can be purchased through the global sales network of 38 sales offices in Europe, Asia, Africa and America, as well as 16 metal centres in Ukraine, and authorised dealers
Secondary Grinding Ball Mills In secondary ball milling, abrasive and corrosive conditions predominate. The smaller balls [lt; 2#189;, (65 mm)] typically used in secondary milling environments effectively reduce the impact component of wear to the point where grinding media must be primarily designed to reduce abrasive and corrosive wear.
