1. Since the machine vibrates a lot when working, the machine should be installed on the foundation of a reinforced concrete structure. The weight of the foundation can be roughly 8-10 times the weight of the machine, and the depth of the foundation should be greater than the ground where the ground is frozen. Depth, the dimensions provided in the basic drawing are the relative positions of the host and motor anchor bolts and other related parameters, and are not used as construction drawings. It is necessary to leave reserved holes for installing anchor bolts as the basis for secondary grouting. The height and size of the unloading chute are determined on site according to the discharging method of the lower part.
2. Tighten the anchor bolts after the secondary grouting cement is firm. During these processes, a level is needed to measure the level of the machine. The deviation of the level is controlled to less than 2 mm within the width of the front wall of the rack. The inspection of the level of the rack is particularly important. It can ensure that the position of the feed inlet is not in the wrong position. Due to deflection, the crusher may be fed from one side during operation to avoid damage to the equipment due to uneven loads.
3. When installing the motor, in addition to checking the distance from the host machine, you should also check that the motor pulley is parallel to the center of the host sheave to ensure that all V-belts work effectively and consistently.
4. The size of the discharge port should be adjusted according to the particle size and processing capacity of the required product. When adjusting the discharge port, the tensioning spring should be loosened first. After the adjustment is completed, the tension of the spring should be adjusted appropriately to prevent The toggle plate falls off during operation, please refer to the adjustment parts for details.

1. Set up signs to control the paving thickness, such as horizontal standard piles or elevation piles, or pop up horizontal elevation lines or nail horizontal elevation wooden pegs on fixed building walls, grooves and ditch slopes.
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 dry.
3. Before paving, relevant units should be organized to jointly inspect the trench, including axis dimensions, horizontal elevation, geological conditions, such as whether there are holes, trenches, wells, etc. The treatment should be completed and the procedures should be completed before the foundation is made.
4. Check whether the slopes of the foundation trench and pipe trench are stable, and remove floating soil and water on the foundation.

After the crushing production line equipment is ready, it should be operated according to the prescribed start-up sequence. There are five aspects that need to be noted.
1. When starting the main motor, pay attention to the ammeter on the control cabinet. After 30-40 seconds of starting peak current, the current will drop to the normal operating 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 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's belt is adjusted to change the feeding amount. Usually, the material accumulation height in the crushing cavity should exceed 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 opening. At this time, the production capacity of the jaw crusher is ideal. 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 jaw crusher to avoid damaging the machine. When they pass through the jaw crusher, the operator at the next post should be notified immediately to take them out in time to prevent entry. The secondary crusher system caused the accident.
5. When electrical equipment automatically trips, if the reason is unknown, it is strictly prohibited to forcibly start the crushing equipment continuously.

1. When users purchase sand making production line equipment and put it into normal use, a long running-in period is required. Most users, in order to rush the construction period or want to obtain benefits as soon as possible, ignore some small parts that should be paid attention to during the running-in period of the sand making production line. , some users even think that the manufacturer should be responsible for repairing the machine if it breaks down before the manufacturer's warranty period is reached. This is completely inappropriate. Therefore, the machine is overloaded for a long time during the running-in period, resulting in frequent early-stage machine failures. Failure not only affects the normal use of the machine and shortens the service life of the machine, but also affects the progress of the project due to damage to the machine. Therefore, the use and maintenance of the sand making production line during the running-in period should be an important link.
2. Due to the equipment in the sand making production line, different faults will occur after long-term use. How should we deal with minor problems? For people who don't understand, they will be in a hurry and don't know how to start. It will be self-defeating. Therefore, there are corresponding problems here, and only by prescribing the right medicine can the disease be cured. The connection and cooperation of equipment on the sand and gravel production line are very important, especially in the feeding and conveying links. If synchronization cannot be achieved, it is easy to cause blockage or the radiation range is too wide, seriously affecting the efficiency of the sand production line. Equipment also creates some hazards. The sand making production line launched by Shibang Industry has been unanimously verified and tested by experts and users. It is a highly integrated joint production line of mineral processing production line equipment and mining machinery. It is energy-saving and convenient. More importantly, it increases the production volume to the previous level. twice. This production line is suitable for both soft materials and very hard materials. It can also effectively handle materials with high moisture content to prevent clogging of production line equipment.
