The unloading rate of steel plate is the percentage of the material discharged from the steel plate and it is also called the discharge rate. The unloading rate directly reflects the advantages and disadvantages of the steel plate warehouse, which is the main performance index. When the material situation of the steel plate is deteriorating, the storage of the storage is more and more, and the increase of the product and the decrease of the material can reduce the effective flow volume of the steel plate and cause the low discharge rate. The low discharge rate not only makes the steel plate warehouse not good enough to produce the material, but also causes the economic benefit of the steel plate warehouse to be reduced.
The material's fluidity is the key to the ability of the steel plate to be produced normally. Material mobility is subject to many influences. Long backlog of materials, high humidity of materials, moisture from the outside air into the reservoir, the reservoir bottom humidity, and some artificial improper operation are all causes of the material fluidity.
The material tonnage is too large, the material level is too high, so that the material density is increased, the storage pressure is increased in the base, and the material compaction reservoir is lower, and the fluidization performance is lower. If the material is not activated for a long time, it will cause the material to die and the material will be difficult. This phenomenon usually occurs during the off-season of materials sales, when the volume of materials is much larger than the sales volume. In order to avoid the storage of material for long time, the use of the outer circulation air force system should be used to loosen the base material.
The moisture content of the powder material itself is high, and the material fluidization can be reduced or expired. In this case, the water content of the materials should be minimized by the use of the water content before entering the warehouse strictly. The more dry the material, the better the fluidization activity, the more difficult to compaction.
The base layer of the base cement has not been thoroughly dried and has not been taken effective moisture-proof measures. The bottom of the reservoir has caused the material humidity of the base material to increase the adhesion and the material is difficult. In addition, some party a USES the unit to wait for the cone natural air drying to require the advance incoming material, so the implementation of the base moisture-proof measures is particularly critical.
When to loose material at the bottom, sometimes use air compressor air pressure are provided by the, if the moisture in compressed air compressor to provide effectively in addition to water, also can make the material because of the humidity increase adhesion affect discharging into pieces. The use unit shall ensure that the air compressor in use is normally operated in addition to the water device, and timely drain the gas tank.
