Rotary kiln and cooler running single-Jane has the following characteristics; ① low speed, such as the speed of a roller boat for 5-15 rev / min; ② overloading, such as roller bearings to withstand the pressure from a few dozen to several hundred tons t; ③ high ambient temperature, Simplified surface temperatures up to 200 ℃ or more, a lot of radiation to the surrounding heat; ④ dust, end seal point, unloading point and chimneys have dust flying overflow; ⑥ single kiln and cooler Jane tilt installation, so the low-end bearing easily spill. To make one simple rotary kiln and cooler safe and stable operation, good lubrication of the various components of great significance. Lubricant selection principle is; slow, heavy duty, high temperature by the impact load, a large selection of dry skin lubricant; high-speed, light-load, low temperature, the viscosity of the lubricant should be selected; withstand large pressure-resistant components made pressure lubrication Park, parts influenced by humidity, in addition to the viscosity, we must also consider the flash point and pour point oil. In the selection of grease should be considered when conditions are: to prevent dust from entering the interior of the bearing components as appropriate; without regular checks of parts; certain high temperature, heavy, slow parts, under high temperature conditions should use sodium based grease in humid environment, should be used calcium-based grease.
