How to choose the right broken cone lubricant?

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.

First, the season is different, the lubricant is different

  • 1. The temperature from winter to spring is relatively cold, it is recommended to use relatively slippery lubricating oil; most of the autumn continues the high temperature in summer, so it is recommended to use relatively thick lubricating oil.
  • 2. The viscous lubricating oil will become more viscous at low temperature, which is not conducive to the application of the parts that need lubrication, and the relatively smooth lubricating oil can achieve the effect we want; the thick lubricating oil at high temperature It will become relatively slippery and can adhere well to the parts of the equipment that need lubrication. If a very slippery lubricant is used, the adhesion on the lubrication system is relatively poor.
  • 3. The lubricating oils that can be used in different seasons are as follows: general temperature is 40# mechanical oil in spring and autumn, mechanical oil No. 20 or 30 in winter, mechanical oil No. 50 in summer, No. 10 or 15 in winter in alpine region. Mechanical oil to meet the normal operation of the equipment.

Second, the component pressure is different, the lubricant is different

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.

Third, the component speed is different, the lubricant is different

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.
