how to avoid temperature rise of rotary kiln bearing bush

how to avoid temperature rise of rotary kiln bearing bush

The rotary kiln is mainly composed of a cylinder, a transmission device, a supporting device, a wheel blocking device, sealing of kiln head and kiln tail,and a kiln head cover. The supporting device of the supporting rollers carries the weight of the whole kiln barrel, and plays a positioning role on the barrel, so that it can run safely and smoothly. The temperature rise of rotary kiln support rollers is a common phenomenon, and there are many causes.

If the lubricating oil of the bearing wheel is not changed or maintained for a long time, it will cause the viscosity of the lubricating oil to decrease, the emulsification of the oil quality, and the dust impurities in the oil, etc., which can cause the bearing bush to heat up. Only by regularly replacing the new oil and strengthening the daily maintenance of the roller bearing can we effectively prevent the temperature rise of the roller which caused by the lubricant.

If the seal of the idler shaft is damaged, oil leakage will occur, the oil level will decrease, or the lubricating oil spoon will fall off, which will cause the bearing bush temperature to rise. Therefore, it is necessary to do the routine inspection of the roller seal, replace the seal ring in time, and tighten the lubrication spoon.

If the circulating water system is not cleaned for a long time, the pipeline will be blocked, causing the circulation water to flow improperly or in a small amount, which will cause the bearing shell to heat up. When the circulating water pipe inside the idler is aging and ruptured to produce water leakage, the viscosity of the lubricating oil is destroyed, the oil quality is deteriorated, and the temperature of the bearing shell rises. The treatment measures are: pickling the circulating water pipe, removing the internal oily impurities, and replacing the damaged internal water pipe.

The idler bearing is used for a long time, and the contact angle between the bearing and the shaft will become larger and larger due to friction. At the same time, the contact gap between the bearing and the shaft will become smaller and smaller to a certain extent. Lubricant cannot enter the bottom of the bearing for lubrication. Causes bearing bush temperature rise. After finding that the gap of the tile opening is small, it should be repaired in time and the tile opening should be reopened. Generally, the gap of the tile opening is 0.003Dmm (D is the diameter of the supporting shaft).

FEECO is a leading manufacturer of highly engineered, custom rotary kilns for processing solids. Our high temperature kilns have earned a reputation for their durability, efficiency, and longevity. We offer both direct- and indirect-fired units.

Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum.

Direct-fired kilns utilize direct contact between the material and process gas to efficiently process the material. Combustion can occur in a combustion chamber to avoid direct flame radiation, or the flame can be directed down the length of the kiln.

All FEECO equipment and process systems can be outfitted with the latest in automation controls from Rockwell Automation. The unique combination of proprietary Rockwell Automation controls and software, combined with our extensive experience in process design and enhancements with hundreds of materials provides an unparalleled experience for customers seeking innovative process solutions and equipment.

Indirect-fired kilns are used for various processing applications, such as when processing must occur in an inert environment, when working with finely divided solids, or when the processing environment must be tightly controlled.

Calcination refers to the process of heating a material to a temperature that will cause chemical dissociation (chemical separation). This process is used frequently in the creation of inorganic materials, for example, the dissociation of calcium carbonate to create calcium oxide and carbon dioxide.

Thermal desorption is also a separation process. This process uses heat to drive off a volatile component, such as a pesticide, from an inorganic mineral, such as sand. The component is vaporized at the increased temperature, causing a separation without combustion. In some cases, an indirect rotary kiln would be best for this application, because the volatile chemicals may be combustible. The indirect kiln will supply the heat for desorption, without the material coming into direct contact with the flame.

Organic combustion refers to the treatment of organic wastes with the intent of reducing mass and volume. Organic waste is treated in the kiln, leaving behind an ash with considerably less mass and volume. This allows for more efficient and effective deposit of waste materials into landfills.

Sintering is the process of heating a raw material to the point just before melting. This increases the strength of the material, and is commonly used in the proppant industry, where sand or ceramic materials are made stronger.

Heat setting involves bonding a heat resistant core mineral with another, less heat resistant coating material. Unlike an unheated coating process, here, a rotary kiln heats the coating material to just below liquefaction point, allowing it to coat the heat resistant core more evenly and more securely. This process is commonly seen in the manufacture of roofing granules, where a mineral such as granite is coated with a colored pigment, producing a product that is both durable and aesthetically pleasing.

Reduction roasting is the removal of oxygen from a component of an ore usually by using carbon monoxide (CO). The CO is typically supplied by mixing a carbonaceous material such as coal or coke with the ore or by feeding it separately. Examples are the reduction roasting of a hematite containing material to produce magnetite that can be magnetically separated. In the Waelz process, zinc oxide in steel mill wastes is reduced to metallic zinc and volatilized for recovery in the off-gas system.

The advantages to a FEECO rotary kiln are that it is built to the highest quality standards and is backed by over 60 years of process design experience. The FEECO Innovation Center offers batch and pilot scale kilns that can simulate conditions in continuous commercial rotary kilns, allowing our customers to test small samples of material under various process conditions, as well as part of a continuous process. With options in both co-current and counter-current flow, and direct or indirect configurations, the FEECO test kilns offer a variety of options to suit your thermal testing needs. We also offer support equipment such as a combustion chamber, afterburner, baghouse, and wet scrubber for testing.
