Tumbler Screener Machine mesh replacement steps and precautions

The Tumbler Screener Machine is a highly efficient, energy-saving and environmentally friendly screening equipment, mainly used for the screening and classification of solid materials. Its core component is a drum installed at an inclined angle, and the surface of the drum is covered with screen holes of different sizes and shapes. When the drum rotates driven by the driving device, the materials enter from one end of the drum. With the rotation of the drum and the inclined angle, the materials keep tumbling, being thrown up and falling inside the drum, thus achieving the purpose of screening.

Before installing the screen of the Tumbler Screener Machine, preparatory work needs to be done.

Prepare tools and operations:

• Tool preparation: Prepare all kinds of tools required for installation, such as wrenches, screwdrivers, hammers, pliers, wire rope clips, tensioning devices, measuring tapes, scissors, electric drills, sandpaper or files, etc., to ensure that the tools are complete and can be used normally.
• Material preparation: According to the installation method of the screen mesh, prepare the corresponding materials, such as bolts, nuts, washers, wire ropes, welding electrodes, etc. At the same time, prepare some lubricating grease to lubricate the installation parts of the screen mesh, which facilitates installation and reduces wear.

Safety Protection Measures

Steps for Replacing and Installing the Screen Mesh of a Tumbler Screener Machine:

1. Preparation Work: Cut off the power supply of the equipment, hang a sign saying “Do Not Close the Switch” to ensure that the operation is carried out when the power is off. Clean up the sundries around and inside the Tumbler Screener Machine, prepare appropriate tools and a new screen mesh, and check the specifications and quality of the new screen mesh.
2. Dismantle the Old Screen Mesh: According to the fixing method of the screen mesh, use the corresponding tools to remove the fixing parts. If it is fixed by bolts, use a wrench to unscrew the bolts; if it is fixed by wire rope tension, loosen the wire rope clips first and then remove the wire rope. Carefully remove the old screen mesh from the drum, and pay attention to avoid damaging the surface of the drum.
3. Clean the Drum: Use sandpaper or a file to remove the burrs, rust stains and residual materials on the surface of the drum to make the surface of the drum smooth and flat. Wipe the drum with a clean cloth to ensure that there is no residual sundries. If necessary, a cleaning agent can be used for cleaning, but be sure to dry it to prevent rusting.
4. Install the New Screen Mesh: Lay the new screen mesh flat on the drum, and align the center of the screen mesh with the center of the drum. For screen meshes with special installation direction requirements, install them according to the required direction.
5. Fix the Screen Mesh: If it is fixed by bolts, insert bolts at the positions corresponding to the installation holes on the drum at the edge of the screen mesh and tighten the nuts to ensure that the screen mesh is firmly fixed. Pay attention to the uniform tightening force of the bolts to avoid uneven stress on the screen mesh. If it is fixed by wire rope tension, first pass the wire rope through the fixing holes or rings at the edge of the screen mesh, then fix both ends of the wire rope at the corresponding positions on the drum with wire rope clips, and adjust the tension of the wire rope through the tensioning device to make the screen mesh stretch tightly on the drum.

Final Inspection

Inspection and Adjustment: Check whether the screen mesh is firmly installed, and see if there are any signs of looseness, wrinkles or distortion. Rotate the drum and observe whether the screen mesh fits closely with the drum, and check for any local friction or collision. If there are any problems, make adjustments in a timely manner.

Trial Run: Connect the power supply and conduct an unloaded trial run. Observe whether the equipment operates smoothly, and check if there are any abnormal vibrations, noises or looseness of the screen mesh. After running without load for a period of time, if there are no problems, a loaded trial run can be carried out to check the screening effect and the operation status of the equipment, ensuring that the screen mesh is installed correctly and can work properly.

Winding-up Work: After the trial run is normal, clean up the site and put away the tools. Properly store or dispose of the replaced old screen mesh.
