Exploring the key points of Intermittent asphalt mixing cement silo operation
2025-03-14
The correct operation of Intermittent asphalt mixing cement silo is crucial to ensure the quality of asphalt mixture and the efficient operation of the mixing plant.
1. Key points of feeding operation
Before feeding, first ensure that the inside of the cement silo is clean, dry and free of debris. Check whether the feeding pipeline is unobstructed and whether the valve is in the correct open or closed state. During the feeding process, the feeding speed should be controlled to avoid too fast causing cement to have a large impact in the silo, which may damage the silo structure or cause excessive dust. At the same time, pay close attention to the indication of the level meter to prevent cement from overflowing out of the silo, causing waste and environmental pollution.
2. Key points of discharging operation
When discharging, ensure that the discharging valve can be fully opened and unblocked. For discharging equipment such as screw conveyors, check whether their transmission parts are normal and whether the lubrication is good before starting. According to the mixing requirements, the discharging amount is accurately controlled, which requires the operator to be familiar with the mixing formula and perform the discharging operation according to the specified proportion. During the discharging process, pay attention to observe the continuity of the discharging. If the discharging is not smooth, stop the operation in time and check whether it is a valve failure, screw blockage or other reasons.
3. Silo pressure control
During the use of Intermittent asphalt mixing cement silo, the internal pressure should be maintained appropriately. On the one hand, the dust collector on the top of the silo should work normally to prevent the pressure in the silo from being too high. On the other hand, it is necessary to avoid the formation of negative pressure in the silo due to excessive discharging or other reasons, which will affect the stability of discharging and the safety of the equipment. Check the pressure monitoring device of the silo regularly to ensure that it accurately reflects the pressure in the silo.
4. Safe operation
Operators must strictly abide by the safety operating procedures. Set up obvious warning signs around the Intermitttent asphalt mixing cement silo, and it is strictly forbidden for unrelated personnel to approach. When performing silo inspection, maintenance and other operations, the power supply must be cut off, and necessary protective measures must be taken, such as wearing a safety helmet and safety rope. At the same time, under severe weather conditions, such as strong winds and heavy rains, safety inspections of cement silos should be strengthened to prevent accidents.
