The lubrication of the cone crusher is a very important part of its daily maintenance. When the cone is broken in the process of crushing the ore, the moving surface inside the equipment will generate a large friction. Good lubrication is necessary to ensure the normal operation of the equipment. Conditions, as the temperature and humidity of the working environment in the cone is changed, the lubricating oil used will also change. This article will share tips for choosing lubricants.
For the components of the cone crusher, parts that work under heavy loads require a more viscous lubricant. For example, when the bearing pressure is large, the oil is pressed out from the bearing and then operated in a dry state, which tends to generate a high working temperature, so a more viscous lubricating oil is used.
When the rotation speed is large, the oil with less viscosity is used; conversely, when the rotation speed is small, the oil with higher viscosity is used. Because too dry or viscous lubricants usually cause a rise in bearing temperature for faster speeds. When the speed and pressure are relatively large, the oil with less viscosity will not be squeezed out of the bearing, because when the shaft rotates, the oil is sucked very strongly, the oil pressure is squeezed between the sliding surfaces, and the sliding surface is separated. , thus forming a liquid friction.
