Foundation preparation of sand and gravel production line
1. Set signs that control the thickness of the paving, such as horizontal standard piles or elevation piles, or pop up horizontal elevation lines or nail horizontal elevation wooden prongs on the slopes of fixed building walls, grooves and trenches.
2. When constructing in a project where the groundwater level is higher than the bottom of the base tank, measures to drain or lower the groundwater level should be taken to keep the base tank waterless.
3. Before paving, relevant units should be organized to jointly inspect the groove, including axis size, horizontal elevation, geological conditions, if there are no holes, trenches, wells, etc. It should be finished and go through the formalities before the foundation is made.
4. Check whether the slope of the foundation groove and pipe trench is stable, and remove the floating soil and accumulated water on the base.
Sand production line operation
After the equipment of the crushing production line is ready, it should be operated in accordance with the prescribed driving sequence. There are five aspects to be noted.
1. Pay attention to the ammeter on the control cabinet when starting the main motor. After 30-40s of starting peak current, the current will drop to the normal working current value.
2. During normal operation, it should also be noted that the current should not exceed the specified value for a long time.
3. After the jaw crusher is in normal operation, the feeder can be started, and the feeding belt can be adjusted according to the size of the material block and the operation of the jaw crusher to change the feeding amount. Generally, the height of the material accumulation in the crushing chamber should exceed 2/3 of the height of the crushing chamber. The diameter of the material block does not exceed 50-60% of the width of the feed inlet. At this time, the production capacity of the jaw crusher is high. When the material block is larger, it will cause blockage and affect the normal production.
4. It is necessary to strictly prevent metal objects (such as shovel teeth, track shoes, drills, etc.) from entering the jaw crusher to avoid damage to the machine. When they pass the jaw crusher, they should immediately notify the operator of the next post to remove it in time to prevent entry Accident caused by secondary crusher system.
After the electrical equipment automatically trips, if the reason is unknown, it is strictly forbidden to start the crushing equipment continuously.
Crushed stone production line maintenance
In the crushed stone production line, the high frequency is the crushing equipment. In order to guarantee higher production efficiency and longer service life, manufacturers of crushed stone production lines must do maintenance work.
1. Bearing maintenance of crushing equipment
The bearing parts of the crushing equipment are easily damaged, so it is necessary to add lubricating oil and grease frequently to ensure the service life of the bearing.
2. Daily maintenance of crushing equipment
In order to ensure that the crushing equipment is in a good technical state, reduce downtime, improve the intact rate and utilization rate, regular maintenance, even mandatory, to properly handle the relationship between maintenance and repair is not allowed to use only maintenance or repair Not raised.
3. Lubrication and maintenance of crushing equipment
Always pay attention to and do a good job of lubricating the friction surface in time to ensure the normal operation of the crushing equipment. The grease added to the bearing housing is 50-70% of the volume and should be replaced every three months. For example, use clean gasoline or kerosene to carefully clean the runway of the bearing rollers when changing oil.
