How to reduce the consumption of vulnerable parts of jaw crusher in high temperature operation
Time: 2021-07-30
Jaw crusher is commonly known as jaw crusher, also known as tiger mouth. The crushing chamber is composed of two jaw plates, a movable jaw and a static jaw, which simulates the movement of the animal's jaws to complete the material crushing operation. It is used for medium-size crushing of various ores and bulk materials in mining, smelting, building materials, highways, railways, water conservancy and chemical industries. The high compressive strength of the crushed material is 320Mpa.
With the advent of July and August, the temperature is getting higher and higher, and when the jaw crusher is working normally, it will generate heat. Coupled with such a high outdoor temperature, the consumption of vulnerable parts of the jaw crusher is More and more serious, if there is no correct measures, then it will definitely increase production costs, and even hinder normal production.
Jaw crusher When working at high temperatures, you should always pay attention to the temperature of the bearing to keep it in a good lubrication state, and pay attention to whether there is abnormal sound and vibration. If it is found to be abnormal, stop and check immediately, find out the cause, and confirm whether it is stuck by a non-breakable object or the hammer head and other parts are damaged.
Secondly, when the machine is running at high speed, the power consumed by friction is all converted into heat, causing the temperature of the friction parts to rise. When lubricating oil is used for lubrication, it continuously absorbs heat from the friction surface to dissipate it, or supplies a certain amount of oil to remove the heat and reduce the temperature of the friction surface.
In addition, the bulk materials in the jaw crusher must meet the crushability requirements, and the strength of the materials must be within the maximum strength that the crusher can handle. In addition, in the crushing process, the crushing cavity should prevent iron and other non- crushed objects from entering it. When the feed materials are mixed together after crushing, there will be uneven strength of various materials. The strong materials will protect the low-strength materials, thereby reducing the crushing probability and product size of the weaker materials.
In addition, due to the strength, the liner of the crushing chamber is not uniformly stressed, which can cause uneven wear of the liner and affect the normal operation of the crusher. Therefore, in order to improve the working efficiency of the crusher, improve the force of the parts of the equipment, and give full play to the function of the lamination crushing in the crushing process, the uniformity of the strength of the feed material should be ensured during the production process.
