Introduction
Impact crusher is a type of machine that uses impact to break down material into smaller pieces. Impact crusher is commonly used in the mining, quarrying, and construction industries. They is also used in some recycling applications.
Safety
Before operating an impact crusher, it is important to read and understand the operator’s manual. The operator’s manual will provide specific instructions for the safe operation of the crusher. It is also important to wear appropriate personal protective equipment (PPE), such as safety glasses, hearing protection, and dust mask.
Pre-Startup Checks
Before starting the impact crusher, it is important to perform a number of pre-startup checks. These checks include:
- Inspecting the crusher for any damage
- Checking the oil levels
- Ensuring that all guards is in place
- Making sure that the feed hopper is empty
Starting the Crusher
Once the pre-startup checks have been completed, the impact crusher can be started. The starting procedure will vary depending on the specific model of crusher. However, the general steps is as follows:
- Turn on the main power switch
- Start the feed conveyor
- Start the crusher rotor
Operating the Crusher
The impact crusher is operated by controlling the feed rate and the rotor speed. The feed rate is the amount of material that is fed into the crusher per unit of time. The rotor speed is the speed at which the rotor rotates. The feed rate and rotor speed should be adjusted to achieve the desired product size.
Shutting Down the Crusher
To shut down the impact crusher, follow these steps:
- Stop the feed conveyor
- Stop the crusher rotor
- Turn off the main power switch
Maintenance
Impact crusher require regular maintenance to ensure that they operate safely and efficiently. The maintenance schedule will vary depending on the specific model of crusher. However, some general maintenance tasks include:
- Checking the oil levels
- Greasing the bearings
- Inspecting the wear parts
- Tightening the bolts
Troubleshooting
If the impact crusher is not operating properly, there is a number of things that can be done to troubleshoot the problem. Some common problems and their solutions include:
- The crusher is not producing enough product: This could be due to a low feed rate, a slow rotor speed, or worn wear parts.
- The crusher is producing too much fines: This could be due to a high feed rate, a fast rotor speed, or worn wear parts.
- The crusher is making strange noises: This could be due to a loose bearing, a damaged wear part, or a foreign object in the crusher.
If the problem cannot be solved by following the troubleshooting steps in the operator’s manual, contact the manufacturer for assistance.
Impact crusher is a valuable tool for the mining, quarrying, and construction industries. By following the safety instructions and maintenance procedures in the operator’s manual, you can ensure that your impact crusher operates safely and efficiently for many years to come.
