make clear & color & printed big jumbo roll from bopp film and glue on same machine by one step.
At least one iron remover shall be installed in the main transport system (large lane, main well and upper warehouse belt conveyor), and the iron separator shall be installed at the joint of the fully integrated belt conveyor and the belt conveyor.
1. The magnetic field strength of the iron separator installed in the continuous mining working face belt machine is not less than 1200 GS; the magnetic field strength of the iron separator installed in the fully mechanized mining belt conveyor and the main transportation system (large lane, main shaft and upper warehouse belt) is not less than 1500 GS. The upper roller and the upper roller frame must not be installed directly under the iron remover.
2. Each district team should contact the coal quality department every quarter to perform a magnetic field strength test on the used iron remover. When the measured magnetic field strength is less than 70% of the designed magnetic field strength, it must be replaced.
3. The iron separator implements the charter management system. Each iron remover must have a charter responsibility card. The liability card must specify the equipment status, charter owner and related technical parameters.
4. A glove box must be set within 5 meters of each iron remover. The iron remover should be started and stopped at the same time as the belt conveyor. After the shutdown, the debris adsorbed on the iron remover should be cleaned up in time.
5. The installation and management of the iron remover shall be carried out in accordance with the “Administrative Measures for Iron Removal of Shendong Coal Branch (Trial)”.
Tape Making Machine
The receiving point of the tape machine must use a buffer bed or other cushioning device to prevent the sharp tape or hard object from tearing the tape. The installation requirements are as follows:
1. The production of the guide groove of all belt conveyors must be standardized, the welding is firm and reliable, the height of the coal is guaranteed to be more than 1 meter, and the lower mouth of the slip nozzle should be smooth, so as to improve the passage of coal flow and prevent large coal or The meteorite caused the tearing accident due to the fact that the guide material was not smoothly caught in the guide groove.
2. Install a set of buffer beds (ie, the installation length is 1.2 meters) at each receiving point. The distance between the surface of the buffer strip and the belt surface shall not be less than 20~30mm, to prevent the surface from sinking due to the long installation length. Increase the wear on the belt surface; the installation clearance between the buffer strips shall not exceed 10 mm, and the gap shall be filled after installation to prevent the iron piece or large piece of coal and vermiculite from penetrating the belt between the gaps of the buffer strip, resulting in Tear the accident.
3. The operation team shall formulate the management system of coal bunker, slip coal eye, and distribution bar scraper (cast stone slab). The bunker must be equipped with anti-smashing bin protection device to prevent coal slip directly from impacting the bottom shrinkage plate and I-beam. Causes deformation and shedding, mixing into the coal slip causes tearing accident.
