The Ball mill can be divided into lattice type and overflow type according to different beneficiation methods, and this machine is two lattice-type ball mill. The materials from the feeding fittings enter evenly to the first bin of the milling machine via the feeding hollow axis when it works. There is a ladder-like or ripple-like scaleboard in the first bin, and different specification steel balls are installed in the bin. When the cylinder rotates and produces centrifugal force, the force carries steel balls into a certain height and then makes them fall to strike and grind the materials. After coarse grinding in the first bin, the material then enters into the second bin via a single layer partition board. There is a scaleboard and steel boards in the second bin, so the materials are further ground. In the end, the powder is discharged by output material board.
That is not so good,I'll give you a website,there you find more. www.grinding-mill.net/vertical_roller_mill.html

Can you use nickel plated steel balls for grinding media in a ball mill?
yes you can use nickel on a ball mill yes you can use nickel on a ball mill
MQG Ball Mill?
The ball mill is widely applied in mineral classification, cement, fireproof materials, glass, pottery, chemical industry and so on. The ball mill can grind all kinds of rocks and grinding materials. There are two ways of grinding: the dry process and the wet process.
What is ball milling process?
Ball mill is an efficient tool for grinding many materials into fine powder. The Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material. The ball mill is a key equipment for regrinding. It is widely used for the cement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc. Our ball mill can grind ore or other materials that can be grinded either by wet process or by dry process. Ball mill is the most common grinding equipment in mining process, and widely applied to the grinding of all kinds of metallic, non-metallic grindable materials. Owing to different ways of classification, ball mill can be called differently. According to dry grinding and wet grinding, ball mill can be divided into dry ball mill and wet ball mill; According to grinding size, ball mill can be divided into grid ball mill and overflow ball mill; According to the barrel length, ball mill can be divided into long cylinder ball mill and short cylinder ball mill.

What determines the steel ball ratio of a ball mill?
The steel ball ratio in a ball mill is determined by the material being milled and the grinding conditions. Generally, a higher steel ball ratio results in more effective grinding and finer particles. However, the optimal steel ball ratio may vary depending on the specific milling process and desired outcome.
How the critical speed of ball mill is determined?
The critical speed of a ball mill is determined by the rotation speed of the mill and the diameter of the grinding media. It is calculated using the formula: critical speed = 42.3/sqrt(d), where d is the diameter of the mill in meters. Operating above the critical speed can lead to cascading and ineffective grinding, while operating below can lead to cataracting and unproductive milling.
In empty ball mill power consumption is more or filled why?
In a ball mill, the power consumption is varied according to the shifting of the centre of gravity in the internal volume of the mill.when the mill is empty, the fraction of volume occupied by the grinding media is more. but when the mill is filled with some feed, as the centre of gravity of grinding media shifts up,the fraction of volume occupied by the grinding media decreases. so power consumption is less.Power =0.285*d(1.073-j)m*nd - internal diameter of millj - fraction of mill volume occupied by mediam - mass of grinding media in tonnesn - number of rotations of the mill
Derivation of critical speed of grinding mill?
The critical speed of a grinding mill is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inner surface, leading to no ball fall and higher efficiency. It is calculated by using the formula: critical speed = 42.3/sqrt(D-d), where D is the diameter of the mill in meters and d is the diameter of the grinding media in meters.
What is the working principle of ball mill?
The ball mill for the installation of horizontal rotating cylinder, outer edge of which lies Gear, two warehouses, lattice-type ball mill. Feed materials from the device into the compound empty-axis spiral uniform access to the first Mill Wharf, the warehouses have stepped liner or corrugated liner, the contents of different specifications Ball, the centrifugal force will have a rotating cylinder ball to a certain altitude sets, and have severe impact on materials and grinding role. Materials in the first positions to grinding, single-layer at the plate in the second warehouse stores, the warehouses incalculable-liner with a ball, will further polishing materials. Discharge through the grate of powder from plate to complete grinding operations.
What is the work bond index of clinker?
The work bond index of clinker refers to the grindability of clinker, which is a measure of the energy required to grind it to a specified fineness. It is determined through laboratory testing using a specific procedure and can provide insight into the efficiency of grinding processes in cement production. A lower work bond index indicates easier grinding and lower energy consumption.
Can I grind wheat at home without a mill or grinding mill?
Yes
What is Opc and ppc grade of cement?
OPC is ordinary Portland cement and PPC is Portland pozolona cement. OPC is obtained by grinding clinker and gypsum whereas PPC is obtained by grinding clinker gypsum and high reactive silica. High reactive silica improves the quality of cement by reducing liberated lime.
What is the name for a hand mill for grinding corn?
