The Types and Texture of Grinding Media of Cement Ball Mill

2015-11-27

During the grinding process of the cement ball mill, the performance of the grinding media determines the grinding efficiency and working ability of the White cement production line. In order to maximize the grinding effect of the ball mill, it is necessary to choose suitable grinding mill. The premise of selecting suitable grinding media is to learn about the types and texture of the grinding mill and this paper will deal with it.
The grinding media with different shapes and sizes have different grinding effect during the powder grinding process. The grinding media that are commonly used in the cement plant can be divided into the following types according to their shape:
(1) Steel ball: Steel ball is a widely used grinding medium of Silica sand grinding mill. According to the powder grinding requirement, the steel ball with diameter of 20~120mm are often selected. As for the coarse grinding cabin of ball mill, various steel balls with diameter of 50~100mm are chosen, and steel balls with diameter of 20~50mm are chosen for the fine grinding cabin.
(2) Steel forges. Steel forge is usually used in the fine grinding cabin of the open circuit Copper ore garnding machine.
(3) Steel rod. Steel rod is a grinding medium that is widely used in the rod mill and its diameter is often 40~90mm.
In the cement industry, the textures of the grinding media of the ball mill mainly are:
(1) High-chromium iron. It is an alloy white iron which has high chromium content with the property of anti-abrasion, anti-heat, anti-corrosion and high toughness. The abrasive resistance of the high-chromium iron ball is 8~12 times of common straight carbon steel ball.
(2) Low-chromium iron. It has low chromium content. Its toughness is relatively low so that it is suitable for being made of the small balls, iron forge and the lining board of the fine Cement clinker grinding process.
(3) Casting bearing steel. It can be made of steel balls with various diameters. The consumption of balls is higher than that of the high-chromium iron balls, but due to its low content of alloy elements, it still has wide application in the mining machinery industry.
When selecting the coal grinding mill plant, the manufacturing company should take a comprehensive account of the advantages and disadvantages of different grinding media and combine the actual situation of the company so as to select the most suitable grinding mill in order to ensure high production capacity of the ball mill.

Measures of Energy Conservation and Emission Reduction of Sand Maker

2015-11-17

The vertical shaft impact crusher can also be called sand making machine, which is researched, developed and manufactured with the stone impacting stone principle and technology. This machine mainly uses the impacting principle to crush the large stone into small one and even into sand. There are mainly three methods that can be used for conserving energy and reducing emission for the sand maker.
1. The tension force of the driving triangle rubber belt should be adjusted to be proper in order to make sure that the load force of the triangle rubber is equal. When the machine is driven by double motors, the triangle rubber on both sides should be grouped and selected in order to try to make the length of every group is the same.
2. The vertical shaft impact crusher machine adopts mobile car used lubricating grease, and after four hundred hours of work, the workers should add proper amount of lubricating oil and after two thousand hours of work, the workers should open the main axis spindle mechanism and cleanse the bearing. The workers should change new bearings after 7,200 hours of work. The upper bearing of the principal axis is the movable part and the lower bearing is the fixed part and after the installation, the workers should pull the belt conveyor to see if it is able to move flexibly.
3. Regularly stop the machine and open the observation door in order to observe the abrasion condition inside the sand maker. The workers should pay attention to the abrasion degree of the central material feeding pipe, cone cap, the upper and lower lining board of the impeller, the surrounding baseboard and if they are abraded, they should be timely changed or repaired. It is forbidden to open the observation door during the working process of the crusher in order to avoid danger.
