Fote Machinery has summed up key factors influencing the liner wear of a ball mil based on years of production experience, which as a reference for the users of ball mill. Hope it can help the users avoid a similar situation in production and prolong the service life of ball mill liner plate. The key factors influencing the liner wear of a ball mill generally include the following several points: 1, The impact of media material: The generally used crushing media mateial include: various mine materials (manganese, copper, tungsten ore, chrome ore, etc.), various types of stone (limestone, granite, gneiss, basalt, gray rock, etc.) and industry coal used in power. The hardness of the media is the main basis that determines the liner plate wear, the higher hardness of the media, the shorter service life of the liner, on the contrary, if the media is with a lower hardness, the service life of the liner will be prolonged. 2, The impact of operating conditions: 1) Eliminate defects not timely; 2) Adjusting undeservedly makes the ball mill running at a short positions. 3, The impact of liner material: The main parameters affecting the anti-wear effect is matching of the two index of hardness and impacting toughness of liner material. If the liner plate has a higher hardness, which means it has a good wear resistance, and the two factor basically is a proportional relationship. The impacting energy depends on the size of the diameter of steel ball and grinding tube. 4, the impact of the ball mill's designing and manufacturing and the installing quality. The performance of the lining plate generally include the following two: one is to protect the cylinder; another is that the liner plate rotates at a specific speed to raise the ball to the required height to achieve the desired effect.   rod grinding mill: http://www.ftm-ore-beneficiation.com/pro/rod_mill.html
It is from the last century that people from foreign country had optimized the structure and cavity of the jaw crusher by the computer simulating technology, they had developed the new jaw crusher with characteristics of no plug point, low height, light weight, good product particle, high yield, high performance and low power consumption, which thereby greatly improved the performance of the jaw crusher, shortened the developing cycle of product and improved the competitiveness of the product in the market. However, the simulating optimization design of the jaw crusher in China was mainly limited to the specific models of jaw crusher to prepare the corresponding procedure to optimize the design. And these procedures are mostly with little reusability, which can only solve the specific issues of particular jaw crusher. However, the optimized content of a crusher changes frequently with different requirements of different customers, so the simulation optimization design work needs large repeated and cumbersome programming work, which is time-consuming and laborious as well as extends the developing cycle of the product. Try to use the advanced design tools of kinematics and dynamics simulation to have a rapid development of the new jaw crusher and to have a simulating optimization design of the mechanism design parameters, which greatly reduce the workload of the simulation design, shorten the product development cycle and improve the reusability of the simulating model. To optimize the jaw crusher by the use of simulating technology, the main task is to optimize the feeding, discharging horizontal and vertical stroke and stroke characteristic coefficient of a jaw crusher. Jaw crusher is widely used in mining, metallurgy, building materials, highway, railway, water and chemical industries. The jaw crushers of Henan Fote Machinery Mine Machinery CO.,LTD. gathers the successful experience of the similar products at home and abroad. Among them some large and medium-sized the jaw crushers are the main products. Especially in designing and producing large jaw crusher, we has been a leading level at home and abroad. Henan Fote Heavy Machinery Co., Ltd is a joint-stock mining machinery manufacturing enterprise integrated in scientific research, production and marketing of spiral washer, small mobile crusher and other commonly used mining equipment, welcome to visit and cooperate with us. Thank you! jaw crusher manufacturers: http://www.chinafote.com/pro/p1.html
When the ball mill rotates at a low speed, the ball of mill ball raised at a low height, the ball will roll down from the top of the ball charge because of its own gravity and presents a cascading state, at which time the impact force of the ball is very small but the grinding effect is evident. However, the ore is mainly ground by grinding and the grinding efficiency is not high. When the ball mill rotates at a high speed, the ball will be lifted highly. After the ball is lifted to a certain height, it will separate from the barrel and falls along a parabolic trajectory in throwing working state. The ball will gain a great impact at the drop point. The ore is mainly ground by the impact, and the grinding efficiency is high. When the rotating speed of the ball mill exceeds a certain limit ( speed is very high ), the ball will rotate with the cylinder to rotate without falling in centrifugal running state. The ball will not gain any impact which means no grinding efficiency.Scientific management, advanced processing technology and innovative manufacturing theory make Fote Heavy Machinery become the exporting base of ball mill manufacturer, small ball mill for sale and famous grinding equipment in China. What Hongxing has done is for the clients and we believe that quality is the best way to develop market. The control of the rotating speed of a ball mill not only relates to the grinding effect, but also relates to the service life of a ball mill. For example, nowadays the ball mill is designed and manufactured below the critical speed. If it rotates at the critical speed or supercritical speed movement, firstly, it will lost its grinding performance because of the centrifugal force; secondly, the high speed rotating will cause mechanical vibration and abrasion, the service life of the equipment is greatly reduced.  At the Fote time the grinding effect of the internal ball mill damages, discharging thickens and it also increases the graded load, so that products are not up to the qualified size requirements. So it is more important of controlling the rotating speed of a ball mill.   slag mill: http://www.chinafote.com/pro/p58.html
The generally used technology of testing the instantaneous load of the crushing cavity is the amount of actual ore beneficiation testing technology. The load of a crusher affects the product size and the energy consumption of the crusher, and affect the normal operation of the crusher as well, thus, the users should promptly detect the load of a crusher. In the multi-stage crushing of a crusher, the detection generally aims at the load of a crusher in the last stage of the controlling final product size, in which stage the crusher is usually working in a closed system. The amount of the feeding materials into the crushing section include the previous crushing stage and cycle loading amount. The load testing of the last stage mainly include the following four methods: 1) Use the contact sonding device directly indicating the material level of the crushing cavity, through we will know the load. 2) Test the current value in the motor circuit of the crusher; 3) Use the belt conveyor scale and other weighing belt conveyor to convey the materials into the crusher, which we can read the delivery throughput directly;Scientific management, advanced processing technology and innovative manufacturing theory make Fote Heavy Machinery become the exporting base of mobile crusher machine, spiral washer and famous grinding equipment in China. What Hongxing has done is for the clients and we believe that quality is the best way to develop market. 4) We can also know the load by the calculating the cycle load of crushing, screening closed-loop system. The former two methods directly reflect the size of the instantaneous load in the crusher cavity. The two methods have the characteristics of testing convenient, easy to adjust in time and can compose a automatic control systems with the automatically adjusting device. As with the third method, it has the former two advantages besides it can not directly reflect the crusher cavity load. However, it need to add a device of the dressing plant. When the particle size of the feeding materials is too large, the weighing accuracy of belt conveyor scale is low, so this method is little used. The fourth method can only reflect the average load of a crusher in a period of time, which can not achieve timely regulation. glass crusher: http://www.china-ftm.com/pros/concrete-crusher.html
