Henan Benteng Machinery Co.,ltd is an enterprise that mainly produces a variety of mining machines and integrates scientific research, production and sales. After years of experience accumulation and development, it has formed a complete comprehensive process innovation system, and it also has processing capabilities. , processing, assembly, packaging, shipping and other complete supporting production equipment and formal production capacity, and provides complete after-sales service, has a good reputation, and is relatively reliable in terms of the reputation of the manufacturer and the quality of the equipment.
When users conduct manufacturer inspections, they can also choose several for comparison. Benteng Machinery’s new ball mill has obvious advantages: high grinding rate. The ball mill is the key equipment for crushing the materials after they have been crushed. This type of grinding machine is filled with a certain number of steel balls as grinding media in its barrel. It is generally widely used in cement, silicate products, new building materials, refractory materials, black and non-ferrous metal mineral processing, glass and ceramics and other production industries, for dry or wet grinding of various ores and other grindable materials.
The main working part of the ball mill for grinding materials occurs on the horizontal low-speed rotating cylinder. When the cylinder is driven to rotate by the transmission device, the grinding body is attached to the lining surface of the inner wall of the mill cylinder due to the inertial centrifugal force. They rotate together, are brought to a certain height, and fall freely by gravity. At this time, the grinding body crushes the materials in the cylinder. At the same time, in addition to the cyclic motion of rising and falling, the grinding body also produces Sliding and rolling cause grinding action between the grinding body, lining plate and the material to be ground to grind the material into fine pieces.
Structure and composition
The ball mill is composed of the feeding part, cylinder, feeder, discharging part, rotary part, transmission part (reducer, small transmission gear, motor, electronic control) and other main parts. The hollow shaft is made of cast steel with a removable inner lining. The rotating gear is hobbing from castings. The cylinder is inlaid with a wear-resistant lining plate, which has good wear resistance. The machine runs smoothly and works reliably.
As the core equipment of the grinding operation, the ball mill is notorious for its high energy consumption. According to relevant statistics, the energy consumption of the grinding operation can account for 40% to 50% of the total energy consumption of the dressing plant. Therefore, over the years, various Manufacturers are constantly exploring and researching on energy-saving issues of ball mills. The same is true for benteng. The new ball mill has replaced the traditional ball mill and become the new favorite in the grinding industry. There is a reason why it can win the favor of the majority of mining owners. The new ball mill has many advantages. The core advantage is low energy consumption. Its energy consumption is only 70% of the traditional ball mill of the same specification. For other advantages, please let the editor explain to you the advantages of the ball mill in detail.
1、Ball mill has low energy consumption
The appearance of the new ball mill is similar to that of the traditional ball mill. It is also a horizontal structure and can work continuously. The structure is also similar. It is composed of a cylinder, large and small gears, a frame, a lubrication device, a transmission device, etc. The difference is that the motor of the new ball mill is different from the traditional ball mill. This ball mill is equipped with a special motor for grinding. The starting current is lower than other ball mills. The motor itself consumes less mechanical and thermal energy and transfers more energy to the ball mill, thus Reduce power consumption.
In addition, the new ball mill replaces the bearings and replaces the sliding bearings with large double-row spherical roller bearings. From a physical point of view, the use of this bearing is more conducive to the startup of the ball mill. After startup, due to the effect of inertia, the cylinder can Continuous and stable rotation naturally reduces energy consumption a lot. Tests show that the energy consumption of the new ball mill is 70% to 80% of that of the traditional ball mill, which means it saves 20% to 30% more energy than the traditional ball mill. It can be seen that the advantages of the new ball mill are still obvious.
2、Ball mill has high grinding efficiency
Of course, in addition to low energy consumption, the new ball mill also has the characteristics of high grinding efficiency. The equipment has enlarged the ore discharge port, and the products with qualified particle size can be discharged quickly, avoiding the over-grinding phenomenon caused by the qualified products staying in the cylinder, and also avoiding Continuing to grind qualified products causes a waste of efficiency. Unqualified products can be fully ground, and qualified products can be quickly discharged from the ore discharge port, effectively improving the grinding efficiency.
The use of the corrugated lining plate can fully fit the lining plate and the steel balls, fully lift the steel balls and materials, strengthen the grinding effect, and reduce energy consumption. Production examples show that the grinding efficiency of the new ball mill is about 40% higher than that of the traditional ball mill of the same specification.
3、The wearing parts of ball mill have longer service life
In terms of lining selection, the new ball mill uses a wear-resistant rubber lining, which is developed using nanotechnology. Its wear resistance is several times that of ordinary rubber. Compared with linings made of other materials, the life of the rubber lining is longer. It is longer and more convenient to replace, which solves the problem of difficulty in replacing the liner of the ball mill.
In the lubrication system, an oil mist lubrication device is used. The activation of this device ensures reliable lubrication of the large and small gears, thereby extending the service life of the large and small gears.
