China High performance Bearing for Cement Industry
We are well aware of the harsh operating environment of cement equipment and the changing trend of the industry. We are willing to understand the business of our customers and strive to provide reliable and high-quality bearing products for each application environment. We cooperate with our customers to customize personalized friction management solutions for our customers. We take the initiative as the development idea, and actively establish cooperation with cement equipment manufacturers and cement plant maintenance team to improve productivity and minimize downtime.
Bearings used in cement equipment are mainly of the following:
— Spherical Roller Bearings
— Tapered roller bearing
— Cylindrical roller bearing
— Spherical plain bearing
— Insert bearing with housing
— Deep groove ball bearing
— Slewing ring
The vertical mill of industrial cement is not only suitable for the cement industry, but also for the grinding of medium hardness materials such as coal, coke, cement raw materials, gypsum, barite, phosphate rock, decomposition stone, kaolin, etc. in metallurgy, building materials, chemical industry, electric power and other industries. It integrates grinding, drying, grinding and powder selection, with small construction area, roll turning out, maintenance and other features.
According to these characteristics, we have developed a series of bearing products which can meet the working conditions. Among them, the grinding roller is the main part of rolling and grinding materials. In order to work in the drying gas of more than 180 degrees with large load rolling, and the particle size of the grinding material is large, the maximum can reach about 5% of the diameter of the grinding roller, generally 40-100 mm, so there is a large impact load. Through the optimization design of the bearing structure, the use of high-quality steel and proper adjustment of heat treatment process, the service life of the grinding roller bearing is increased to more than 40000 hours. The grinding disc is fixed on the output shaft of the reducer, and the upper part of the grinding disc is a material bed on which the material is crushed by four grinding rollers. Generally, the bearing of the grinding plate adopts the dynamic and static pressure bearing, but the cost is high and the processing is difficult. The coatmaster rotary table bearing processed by special technology has the characteristics of strong bearing capacity and simple installation. The reducer bearing can meet the requirements of large transmission ratio and large load.
In the harsh application environment of the cement industry, coatmaster’s full range of high-performance bearing solutions adopt the engineering technology independently developed by Timken Company in materials, surface processing, contact surface geometry and coating, which can help our customers reduce equipment design and The total cost of operation, in order to enhance competitiveness, so as to reflect the value of Timken products and the value-added for you. For the harsh environment, our high-performance bearings can:
- improve bearing performance and prolong bearing life
- Increase the power density, and the bearing capacity of high-performance bearing is higher under the same installation space
- Reduce bearing replacement cost and equipment maintenance cost
- increase equipment uptime and productivity
- maximize value and improve bearing cost performance
- crusher
- grinder
- vibrating screen
- ball mill
- cement rotary kiln
- Supporting wheel
- roller press
The operation of the above mechanical equipment is closely related to the selection and use of bearings. However, in the cement production process, due to the complex production conditions, many people have no idea about the selection and installation of bearings.
The cement production line is mainly composed of crushing and pre homogenization, raw material preparation homogenization, preheating and decomposition, cement clinker burning, cement grinding and packaging. Bearings mainly include roller press main shaft bearing, vertical mill roller bearing, vertical mill curved arm bearing, cement rotary kiln supporting wheel, retaining wheel and pinion bearing, ball mill main shaft bearing, crusher bearing, etc. Although there are many kinds of bearings, their main working characteristics are low speed and heavy load, large impact, so the bearing with high bearing capacity, impact resistance and high reliability is the only choice for enterprises.
In the process of cement production, the bearing life will be accelerated due to the influence of large dust, moisture, high temperature, vibration and other factors. The guarantee and extension of bearing life need to start from both ends, one is the production link, the other is the use link. Coatmaster thinks that the installation at the end of use is the most important. Coatmaster Technology Department provides guidance for bearing installation in cement plant to ensure the normal operation of bearing as the core hub.
