An efficient, energy-saving and environmentally friendly production line does not only depend on high-quality crushing equipment, it is even more inseparable from the good connection and cooperation between the various equipment, and to maintain the efficient and stable working state of the equipment, it is necessary to do a good job of daily maintenance and repair work.

Previously, the editor also introduced the operation and maintenance of several commonly used crushing equipment. Interested friends can click to view:

1. Preparations for installation

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

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

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

4. Check whether the slope of the foundation trench and the pipe trench is stable, and remove the floating soil and accumulated water on the base.

2. Precautions for operation

After the crushing production line equipment is ready for work, it should be operated in accordance with the specified driving sequence. There are five aspects to pay attention to:

(1) When starting the main motor, pay attention to the ammeter on the control cabinet. 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 according to the size of the material block and the operation of the jaw crusher , adjust the Vibrating Feeder belt to change the feed amount. Usually, the height of material accumulation in the crushing chamber is more than 2/3 of the height of the crushing chamber. The diameter of the material block should not exceed 50%-60% of the width of the feeding port, and the production capacity of the jaw crusher is high at this time. When the material block is larger, it will cause blockage and affect normal production.

(4) It is necessary to strictly prevent metal objects (such as shovel teeth, crawler 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 timely Take it out to prevent accidents from entering the secondary crusher system.

(5) When the electrical equipment automatically trips, if the reason is unknown, it is strictly forbidden to forcibly start the crushing equipment continuously.

3. Maintenance points

In the crushing production line, the most frequently used crushing equipment is the crushing equipment. In order to ensure high production efficiency and long service life, production line manufacturers must do a good job of maintenance.

(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 integrity rate and utilization rate, it must be regularly maintained, or even mandatory, and the relationship between maintenance and repair must be properly handled. It's just not cultivated.

(3) Lubrication and maintenance of crushing equipment

Regular attention and timely lubrication of the friction surface can ensure the normal operation of the crushing equipment. The grease added to the bearing seat is 50-70% of the volume and must be replaced every three months. For example, use clean gasoline or kerosene to carefully clean the track 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 to put it into normal use, it needs a long running-in period. For example, in the feeding and conveying links, if the When it is synchronized, it is easy to block, or the radiation range is too wide, which will seriously affect the efficiency of the production line, and will also 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, resulting in frequent failures in the early stage, which not only affects the normal use of the machine, shortens the service life, But also because of the destruction of the machine, affecting the progress of the project.

4. Safety production system

(1) Carry out a comprehensive safety production inspection on the crushing production line process every month, summarize and analyze the inspection results, formulate rectification measures, and write written materials by the department in charge of safety for archiving.

(2) The workshop team conducts regular safety inspections, reports any problems to the leaders and professional departments in a timely manner, organizes and handles them quickly, and never allows "sick" operations to ensure the safety of the complete set of equipment in the crushing production line.

(3) For special devices, supplies and important places such as electrical devices, crushing machinery, transportation tools, and protective equipment in the production line, the safety management department and professional technicians should conduct special inspections every year. Problems found in the inspection should be written into written materials, archived for future reference, and solved within a time limit to ensure safe production.

(4) Carry out seasonal inspections on rainproof, lightning protection, heatstroke prevention, antifreeze, antiskid and other work, and take corresponding protective measures in time.

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