Disassembly method and precautions of single cylinder cone crusher

1. Introduction

Single-cylinder cone crusher is a common mining machinery equipment, often used in construction, railways, roads and other projects. During long-term use, it may fail due to wear, aging and other reasons. In order to maintain the normal operation of the single-cylinder cone crusher, timely maintenance and disassembly is very important. Xingaonai will take you to understand the maintenance and disassembly methods of single-cylinder cone crusher to help you solve problems encountered in daily use.

2. Preparation before disassembly

Before maintenance and disassembly, we need to prepare some common tools: wrenches, wrenches, screwdrivers, lubricating oil, grease, cranes, clips, etc.; find a flat and spacious site for disassembly; take safety measures and protective measures to ensure the safety of disassembly personnel.

3. Disassembly method and steps

Cut off the power supply in the high-voltage distribution room, ensure that the machine stops running, and hang a maintenance warning sign

Close the feed hopper and empty the material in the feed hopper.

Remove the protective cover and upper cone on the upper part of the crusher, and be careful not to damage the internal parts of the machine.

Remove the locking nut, and use a wrench to remove the main shaft nut at the bottom of the crusher and put it in a safe place.

Remove the main shaft. Note that there is a cam at the bottom of the main shaft. Be careful not to damage the cam when removing it.

Before removing the crushing shell, you need to separate the shell from the liner above the machine. After removing the liner, remove the conical crushing shell.

After disassembling the conical crushing shell, you need to remove the parts in sequence. Generally speaking, the order of disassembly from top to bottom is: adjustment sleeve, check spring, bearing seat, main shaft, clutch, half coupling and coupling, etc.

When checking the parts inside the machine, you can determine the parts that need to be checked according to the machine maintenance manual. Clean up the debris and damaged parts inside the machine. Early detection and early treatment of problems can reduce the cost of subsequent maintenance.

4. Precautions

Turn off the power and stop the car, hang the maintenance warning sign, and comply with relevant safety regulations, wear safety helmets, gloves and other protective equipment.

Handle with care during the disassembly process to avoid damaging the parts inside the machine.

All disassembly steps must be performed in sequence to avoid confusion in operation and difficulty in correctly installing the machine.

During the disassembly process, ensure that all connecting screws, clips, etc. have been removed to avoid incomplete disassembly and subsequent problems.

5. Maintenance skills

In principle, original parts should be used for replacement.

When replacing parts, pay attention to distinguishing parts in different parts to avoid confusion.

When replacing parts, pay attention to the order of disassembly and installation, and ensure that the disassembly order is opposite to the installation order.

After the replacement is completed, the machine should be tested for function to ensure that the replaced parts are working properly.

6. Summary

Through the above disassembly instructions, there is a certain degree of technical difficulty. Before disassembly, a series of preparations must be made and the corresponding installation process must be carried out. At the same time, safety matters must be paid attention to to ensure the safety of the disassembly personnel to ensure that the disassembly process can proceed smoothly. Regular maintenance and cleaning can ensure the normal service life and efficiency of the machine.
