Different crushing fields, broken materials are different, so how to configure crushing equipment for different types of materials? How to maintain it reasonably? Today we will explain the relevant matters in terms of the hardness of the broken stone.
1. When the hardness of the crushed material is small, the recommended configuration of rocks such as limestone is as follows:
Crawler Mobile Jaw Crusher + Crawler Mobile Impact Crushing Station + Screening Station
This is a standard limestone crushing line. The production line has a compact structure and a small floor space. The entire production line is equipped with a centralized electric cabinet control device, which can realize remote operation, save labor costs, and can grasp the operation state of the production line in real time and realize safe operation.
2. When the hardness of the crushed material is large, the recommended configurations of rocks such as cobblestone and quartz are as follows:
Track Moving Jaw Crusher + Crawler mobile Cone Crusher + Screening Station
This is a standard high-hardness stone crushing production line. Compared with the first one, the crushing scheme uses laminating crushing. After crushing, the aggregate has superior grain shape, less wearing parts, and less wear on the crushing equipment. The equipment has a long service life and a high return on investment.
Meanwhile, an efficient, energy-saving and environmentally-friendly production line depend not only on high-quality crushing equipment, but also on the good connection and cooperation between the various equipment. In order to maintain an efficient and stable working condition of the equipment, it is necessary to do daily maintenance and repair work.
1. Operation precautions
After the crushing production line equipment is ready for work, it should be operated according to the prescribed driving sequence. There are five aspects to be aware of:
(1) When starting the main motor, we should 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 the belt of the feeder is adjusted to change the feeding amount according to the size of the block and the operation of the jaw crusher. Usually, the material stacking height in the crushing chamber is more than 2/3 of the height of the crushing chamber. The diameter of the block should not exceed 50%-60% of the width of the feed port.
(4) It is necessary to strictly prevent metal objects from entering the crusher to avoid damage to the machine. If metal objects are found to pass, the next position operator should be immediately notified and removed in time to prevent entry into the second-stage crusher system and cause an accident.
(5) When the electrical equipment is automatically tripped, if the cause is unknown, it is forbidden to forcibly start the crushing equipment continuously.
2. Maintenance points
In the crushing line, the higher frequency of use is the crushing equipment. In order to ensure high production efficiency and long service life, the production line manufacturers must do maintenance work.
1) Bearing maintenance
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
In order to ensure that the crushing equipment is in a good technical state, reduce the downtime, improve the integrity rate and utilization rate, it must be regularly maintained or even forced. The relationship between maintenance and repair should not be properly maintained.
3) Lubrication and maintenance
We should always pay attention to the lubrication of the friction surface to ensure the normal operation of the crushing equipment. The grease added to the housing is 50-70% of the volume and must be replaced every three months. For example, we use clean gasoline or kerosene to carefully clean the runway of the bearing roller.
3. Safety production system
1) A comprehensive safety production inspection on the crushing production line process every month, and a summary analysis of the inspection results, and formulate corrective measures.
2) The workshop team conducts regular safety inspections, reports problems to the leaders and professional departments in a timely manner, and promptly organizes and processes to ensure the safety of the complete equipment of the crushing production line.
3) For the special equipment, supplies and important places of electrical equipment, crushing machinery, transportation tools, protective equipment, etc. of the production line, the safety management department and professional technicians shall be inspected annually and resolved within a time limit to ensure safe production.
4) Conduct seasonal inspections on rain, lightning, anti-heatstroke, anti-freeze, anti-skid, etc., and take appropriate protective measures in a timely manner.
5) During the holiday period, professional safety management personnel must be arranged to carry out safety inspections, and at the same time, a certain number of safety guards are equipped to ensure safety and security.
