1. Set up signs that control the thickness of the paving, such as horizontal standard piles or elevation piles, or bounce horizontal elevation lines or nail horizontal elevation wooden prongs on the slopes of fixed building walls, troughs and ditches.

2. When constructing in a project where the groundwater level is higher than the bottom surface of the foundation trench, measures to drain or lower the groundwater level should be taken to keep the foundation trench in an anhydrous state.

3. Before paving, relevant units should be organized to jointly inspect the groove, including the axis size, horizontal elevation, geological conditions, and if there are holes, trenches, wells, etc. It should be processed and completed before the foundation is made.

4. Check whether the slopes of the base trench and pipe trench are stable, and remove the floating soil and water on the base.

Operation precautions
After the crushing production line equipment is ready, it should be operated in accordance with the prescribed start-up sequence. There are five aspects that need to be paid attention to:

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 operating current value.

2. During normal operation, it should be noted that the current should not exceed the specified value for a long time.

3. After the jaw crusher is operating normally, the feeder can be started, and according to the size of the material block and the operation of the jaw crusher, the feeder belt can be adjusted to change the feeding amount. Generally, the material accumulation height in the crushing cavity is more than 2/3 of the height of the crushing cavity. The diameter of the material block should not exceed 50%-60% of the width of the feed port. At this time, the production capacity of the jaw crusher is relatively high. When the material block is larger, it will cause blockage and affect normal production.

4. Strictly prevent metal objects (such as shovel teeth, track shoes, drill bits, etc.) from entering the crusher to avoid damage to the machine. When they pass through the jaw crusher, the operator at the next post should be notified immediately and taken out in time to prevent entry The second-stage crusher system caused an accident.

5. After the electrical equipment automatically trips, if the cause is unknown, it is strictly forbidden to continuously start the crushing equipment.

Maintenance points

In the crushing production line, the crushing equipment is the one that is used more frequently. To ensure higher production efficiency and longer service life, the production line manufacturer must do a good job of maintenance.

§ 1) Bearing maintenance of crushing equipment

The bearing parts of the crushing equipment are easily damaged, so lubricating oil and grease need to be added frequently to ensure the service life of the bearings.

§ 2) Daily maintenance of crushing equipment

In order to ensure that the crushing equipment is in a good technical condition, reduce downtime, improve the intact rate and utilization rate, regular maintenance must be done, or even mandatory, and the relationship between maintenance and repair must be correctly handled. It is not allowed to only use no maintenance or repair only. Don't support.

§ 3) Lubrication and maintenance of crushing equipment

Frequent attention and timely lubrication of the friction surface can ensure the normal operation of the crushing equipment. The grease added to the bearing housing is 50-70% of the volume and must be replaced every three months. For example, clean gasoline or kerosene should be used to carefully clean the racetrack of the bearing rollers when changing the oil.

§ 4) Maintenance during the running-in period of the production line

The connection and collaboration of equipment on the sand and gravel production line is very important. When the user purchases the production line equipment until it is put into normal use, it will take a long run-in period. For example, in the feeding and conveying links, if the synchronization cannot be achieved, It is easy to block, or the radiation range is too wide, which will seriously affect the efficiency of the production line and cause some harm to the equipment.

In order to catch up with the construction period, most users ignore some small parts that should be paid attention to during the running-in period, or make the machine overloaded for a long time, leading to frequent early failures. This not only affects the normal use of the machine and shortens the service life, but also due to The destruction of the machine affected the progress of the project.

Safe production system

1) Conduct a comprehensive safety production inspection on the crushing production line process every month, analyze the results of the inspection, formulate rectification measures, and write written materials for inspection by the safety department.

2) The workshop team conducts regular safety inspections, promptly report to the leadership and professional departments if any problems are found, and quickly organize and deal with them. Never allow "ill" operations to ensure the safe work of the entire equipment of the crushing production line.

3) For special equipment, supplies and important places such as electrical equipment, crushing machinery, transportation tools, protective equipment, etc. of the production line, the safety management department and professional and technical personnel are invited to conduct special inspections every year. The problems found in the inspection should be written into written materials, filed for future reference, and resolved within a time limit to ensure safe production.

4) Conduct seasonal inspections for rain protection, lightning protection, heatstroke protection, frost protection, and anti-slip work, and take corresponding protective measures in time.

5) During the holidays, professional safety management personnel must be arranged on duty to conduct safety inspections, and a certain number of safety guards must be assigned to do a good job in safety protection.
