The sand and gravel production line is a special equipment for the production of construction sand and stone materials, which can save 50% energy compared with traditional sand making machines. It can make all kinds of rocks, gravel and river pebbles into construction sand that meets various particle sizes, with uniform sand density and high compressive strength, which is far more suitable for construction than natural sand and sand produced by ordinary hammer sanders. The equipment has the characteristics of reliable performance, reasonable design, convenient operation and high work efficiency. Now it has been widely used in the mining industry, so the sand and gravel production line should be operated in accordance with the prescribed driving sequence. There are five aspects that need attention.
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, also pay attention 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, adjust the feeder belt 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 preferred material block diameter is no more than 50%-60% of the width of the feed opening, and the jaw crusher has the highest production capacity at this time. 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 damage to the machine. When they pass through the jaw crusher, the operator at the next post shall be informed immediately to take them out in time to prevent accidents caused by entering the secondary crusher system.
5. After the electrical equipment automatically trips, if the cause is unknown, it is strictly forbidden to start the crushing equipment continuously.
