Cone crusher is the equipment that plays an important role in the production of mining industry. It can be used as the second or third stage of the production line. There are single-cylinder cone crusher and multi-cylinder cone crusher, which have high efficiency and large crushing ratio. , low energy consumption and other advantages, widely used in building materials, mining, railways, smelting, water conservancy, highways and many other sectors. It is suitable for medium and fine crushing and ultrafine crushing of hard rock, ore, slag, refractory materials, etc.
What should I do if the iron block enters when the cone crusher is working? Because of the entry of iron, key spare parts such as the lower frame, main shaft, and eccentric copper sleeve of the cone crusher have been damaged to varying degrees. It has brought a lot of trouble to the production line, and has also greatly increased the labor intensity of the maintenance workers. Today, let’s take a look at how to deal with the cone crusher and how to prevent it.
The solution to the iron block entering when the cone crusher is working
When the cone crusher is working, the motor drives the eccentric sleeve to rotate through the transmission device, and the mantle rotates and swings under the force of the eccentric shaft sleeve. The section of the mantle close to the concave becomes the crushing chamber. The cone is crushed and impacted multiple times. When the mantle leaves this section, the material that has been broken to the required size falls down under its own gravity and is discharged from the bottom of the cone. When the crusher feeds iron, the iron parts are hard and cannot be broken, and they are stuck between the mantle and concave. At the moment of trying to break, the pressure rises instantaneously, the power also increases, and the oil temperature rises; Iron parts were detected entering the interior of the crusher. After that, the crusher will reduce the pressure, lower the main shaft, increase the ore discharge port, and discharge iron to prevent the damage of the crusher from expanding. But in the process, the damage to the crusher is very large.
At this time, what should I do if the iron block enters when the cone crusher is working?
The following three steps let you solve it easily!
Step 1: Use the hydraulic cavity clearing system to open the hydraulic solenoid valve to reverse the oil supply to the hydraulic cylinder at the bottom of the equipment. The hydraulic cylinder rises under the action of oil pressure and lifts the support sleeve through the end surface of the nut at the bottom of the piston rod.
Step 2: With the continuous lifting of the supporting sleeve, a large opening force is formed between the mantle and concave of the crushing chamber, and the iron blocks stuck in the crushing chamber will gradually slide down under the action of gravity and be discharged from the crushing chamber.
Step 3: If the iron in the crushing cavity is too large to be discharged through hydraulic pressure, the iron ore can be cut with a torch. Discharge from the crushing chamber.
During the above operations, maintenance workers are not allowed to enter any part of the body into the crushing cavity, and the parts inside the cone crusher may move suddenly to avoid personal accidents.
How to prevent the cone crusher from entering the iron block
Prevent the cone crusher from passing iron frequently, mainly from the following three aspects:
1. Strengthen the inspection of the wear of the belt funnel liner, replace it in time if any problem is found, and prevent it from entering the crusher after falling off.
2. Install a reasonable iron remover at the head of the feed belt of the crusher to remove the iron pieces entering the crushing cavity, so that the liner is evenly balanced during the crushing process and avoid damage.
3. Install an electronically controlled pressure relief valve on the crusher. When the detected pressure rises after the iron pieces enter the crusher, open the pressure relief valve instantly to discharge oil, lower the main shaft, and discharge the iron pieces.
The above is about the operation method of entering the iron block when the cone crusher is working and how to prevent the iron block entering when the cone crusher is working. Don’t panic if the cone crusher has iron or other failures during work. It is necessary to shut down the equipment in time, then analyze the fault, judge the cause of the fault, and take effective measures to ensure the continuous and stable operation of the equipment and the orderly production.
