Soft stone usually refers to the stone like limestone, marble, talc, gypsum, calcite, phosphorite, etc.
The classic production line for the soft stone is JAW CRUSHER (primary crusher) + IMPACT CRUSHER (secondary crusher), and with the auxiliaries of vibrating feeder, vibrating screen & belt conveyors.
Regarding of the detail condition, two kinds of techniques are usually adopted in producing manufactured sand, dry way and wet way. Both methods can produce high quality manufactured sand as concrete aggregate. Especially, the dry way can produce not only the manufactured sand used in SMA road surface, but also the powder used in asphalt concrete.

Grinding in Ball Mills: Modeling and Process Control
Dec 22, 2016· The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass
Jan 20, 2016· Ball mill grinding is one method of crushing ore to an appropriate size fraction. Specifically, ore is put into a large receptacle (a drum) and then it rotates slowly around. Inside the receptacle, there are balls, usually made of metal, that as...

Apr 12, 2019· It has various applications in that grinding purpose is what stands at first. Be the miling particles are moisture or dry it will grind. Mostly these balls are used in the manufacturing process. There are various types of balls. Each of the balls has specific features it
Different grinding media produce mineral particles with different surface properties and flotability. In this study, the surface properties and flotation behavior of scheelite particles having a size of 74 + 38 m produced by ball and rod mills were studied through single mineral flotation experiment, scanning electron microscopy (SEM) observation, wettability measurement, and X-ray

Apr 03, 2013· The grinding result is influenced by a number of parameters, especially by the rotational speed of the mill, the grinding time, the ball size, the ratio of the sample quantity to the ball filling as well as the material of the grinding parts. There is a growing demand for fine particles with a fine size distribution especially in the
Their function is to reduce by a grinding process the size of certain materials into a powdery form. The balls are described as Ni-Hard metal balls made of cast-iron, nickel, chromium, magnesium, silicon and carbon. The combination of these ingredients makes the
particles of media - the rods, balls or pebbles. This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage induced primarily by crushing and attrition. In autogenous grinding machines fracture of the media particles also occurs by both impact (self breakage) and attrition.
for dispersing these tiny particles as discrete entities. The production of stable suspensions or dispersions of nano particles actually requires a comminution process, such as a small-media mill provides. On an industrial level, this grinding of coarser particles into the nanometer range or dispersing agglomerated nano-sized primary
For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, the ratio ranges from 1.3:1 to 1.5:1. Some ball mills are separated in to compartments by grates. The grates hold back particles above a certain size for additional grinding. The compartments could contain different ball sizes.
BALL MILLING Ball milling is a method of production of nano materials. This process is used in producing metallic and ceramic nano materials. These mills are equipped with grinding media composed of wolfram carbide or steel. Ball mills rotate around a horizontal axis ,partially filled with the material to be ground plus the grinding medium.
Apr 09, 2015· The drum is loaded with grinding media, such as metal balls or glass sand. The media and the charge is stirred together and thus the grinding takes place. These mills are suited primarily for very fine grinding of soft materials.
Ball mills are filled up to 40% with steel balls (with 3080 mm diameter), which effectively grind the ore. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture.
