The comparison of the advantages and disadvantages of ball mills and vertical mills is that cement manufacturers and beneficiaries choose more equipment when choosing ore mills. This article will compare the advantages and disadvantages of ball mills and vertical mills from the following six aspects:

  • Shape
  • Processing technology
  • Power consumption
  • Noise
  • Cement industry application
  • Material moisture

Ball Mill

What are ball mills and vertical mills?

1. Introduction of ore ball mill

Ball mill is the main equipment for crushing materials after crushing. The drum of this type of grinder contains many steel balls as grinding media. Mineral ball mills are widely used in the production of cement, silicate products, new building materials, refractory materials, fertilizers, concentration of ferrous and non-ferrous metals, glass ceramics, etc., and used for dry or wet grinding of various raw materials. Grind. material. The ball mill is suitable for grinding various minerals and other materials. It can be used in building materials, mineral processing and chemical industries. It can be divided into wet grinding method and dry grinding method. According to the different discharge methods, it can be divided into two types: mesh and overflow.

2. Introduction of vertical mill

Vertical mill is a high-efficiency and energy-saving mineral grinding equipment integrating drying, grinding, grading and conveying. Vertical mills are widely used in cement, electric power, metallurgy, chemical, non-metallic mining and other industries. It is used to grind block, granular and powdery raw materials into the required powdery materials.

Ball mill VS vertical mill: appearance

1. The shape of the ball mill

The ball mill consists of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head. The cylinder is a long cylinder, and the device is fixed on the ground. The shape of the frame is rectangular. It occupies a large area.

2. Shape of vertical mill

The shape of the vertical mill is an upright standing posture, which occupies a small area.

Ball mill VS vertical mill: processing technology

1. Ball mill processing technology

The ball mill processing technology adopts a mechanical grinding method in which steel balls are added as a grinding medium to collide and crush the materials. When the cylinder of the ball mill rotates, the grinding body (steel ball) is attached to the cylinder liner and is taken away by the cylinder due to the action of inertia and centrifugal force and friction. When it is brought to a certain height, the grinding body (steel ball) is taken away by the cylinder due to the action of inertia and centrifugal force. It is thrown down by its own gravity, and the falling grinding body (steel ball) impacts and crushes the material in the cylinder like a projectile.

2. Vertical mill processing technology

The processing technology of the vertical pulverizer uses grinding rollers to crush the materials. The material is placed in the grinding disc and crushed by the wheel-shaped grinding roller. The grinding body (grinding roller) does not produce displacement, but the grinding disc is fixed in the center, and the center axis of the installed grinding disc is driven to make a circular motion.

The comparison of the processing technology between the ball mill and the vertical mill shows that the vertical mill does not need to add grinding media, while the ball mill needs to add steel balls as a process assistant. The vertical mill is a grinding equipment of “material bed crushing”, and the grinding roller of the vertical mill adopts a wheel-shaped arc surface. If one side of the grinding roller surface is worn, it can be used continuously when it is turned over, saving cost. And the operation of turning over and replacing is simple, just through the vertical mill rocker arm.

Ball mill VS vertical mill: power consumption

Comparison of advantages and disadvantages of ball mill and vertical mill, on the other hand, is the comparison of power consumption. Vertical grinding mill has high efficiency and low energy consumption. Compared with ball mills, energy consumption is 40%-50% lower; the single machine has a large production capacity and can use low-voltage electricity;

Ball mill VS vertical mill: noise

1. The noise of the ball mill

Because the ball mill uses the collision of steel balls to crush the materials, the collision between the steel balls and the steel balls, and the steel balls and the cylinder will generate loud noises. It has always been a problem to solve.

2. The noise of the ball mill

The whole system of the vertical mill has low vibration and low noise. The noise has little impact on the workshop and surrounding area.

Ball Mill VS Vertical Mill: Cement Industry

1. Advantages of ball mill in cement processing

Ball mills have advantages in the production of cement raw materials. Because the produced particles are approximately spherical in shape, they are beneficial to the calcination of raw materials and the hydration and hardening of cement. This is the main reason why most clinker mills still use ball mills.

2. Advantages of vertical mills in the processing of cement raw materials

According to the survey of people in the cement industry in my country, the vertical milling of raw materials can save 20% to 30% of electricity compared with ball mills, and the slag grinding can save 30% to 40% of electricity, which has been widely used abroad. Therefore, more and more cement manufacturers in China use vertical mills as cement raw materials production and processing machinery.

Ball mill VS vertical mill: material moisture

1. Ball mill

The material processed by the ball mill can be wet or dry. Therefore, it can almost be called all-in-one in terms of material moisture requirements.

2. Vertical mill

The vertical mill uses dry grinding, and the moisture content of the material is usually within 10%. However, the integrated drying function and the use of hot air to dry materials with high moisture content can also solve the problem of high moisture content in materials. It is an ideal equipment in the milling industry that integrates crushing, drying, grinding, and grading and conveying.
