Description
Technical field
The utility model is related to cement grinding system, and in particular to one kind material wind adverse current ball mill cement grinding system.
Background technology
Existing ball mill cement grinding system is divided into two kinds：One kind is ball mill open system, and one kind is that ball mill is closed
Road system.However, being open-circuit grinding system or closed-circuit grinding system, its core process is that material feeds from bistrique, from mill tail
Discharging, while natural wind enters from bistrique, from mill tail air-out.
There is the following defect that cannot evade in above two system：
First, cold air enters to grind tail from bistrique and, and intake air temperature is low, and air outlet temperature is high, and high-temperature gas is not subject to any
Using and discharge, and ball grinder interior temperature is high, moisture content bad adaptability to supplied materials.When temperature is high in mill, easily there is following disadvantage
End：1) cause mill cement temperatures high；2) cause to grind gypsum dehydration in interior cement；3) cause mill tail bearing or bearing bush temperature high,
The temperature upper limit that even more than it bears, so as to cause to stop production；4) cause to grind interior paste ball paste forging, reduce ball mill mill efficiency,
Yield declines, and energy consumption increases；5) the consumable accessory life-span such as influence mill interior lining panel, partition panel.To supplied materials moisture content bad adaptability, easily go out
It is existing：1) supplied materials moisture content is high, will result in the full mill of grinding machine, stops material and shakes mill；2) supplied materials moisture content is high, because ball grinder interior can not be timely
The function of drying and discharge moisture content is completed, goes out to grind that cement moisture content is high, cement shifts to an earlier date aquation, and intensity significantly declines；3) mill is caused
Having a large amount of steam inside machine can not discharge in time, so as to cause corrosion to consumable accessorys such as mill interior lining panel, partition panels, influence its longevity
Life.
2nd, due to prior art wind, material be from same direction enter mill in, operator can not to mill in air quantity carry out
Adjust on demand.Because if wanting to tune up air quantity quickly to discharge heat and moisture content, abnormal fast driving in mill is will result in, use mill thing
Material runs thick, influences Cement Quality, therefore air quantity adjustment is limited in mill, and cause to grind interior heat and moisture content to discharge in time；Go out Mo Shui
Fineness and the specific surface area fluctuation of mud are big, and qualification rate is low.
Utility model content
The purpose of this utility model is to provide a kind of material wind adverse current ball mill cement grinding system, and the system can be fast
Speed, the temperature being greatly reduced out inside the temperature of mill cement and grinding machine, can also in time the direct band of moisture content in supplied materials
Go out；And by the adjustment to air quantity in mill, stabilize out the fineness and specific surface area of mill cement.
To achieve the above object, the utility model employs following technical scheme：Including ball mill, the mill of the ball mill
Be provided with charging aperture and air outlet at head, be provided with discharging opening and air inlet at the mill tail of the ball mill, described charging aperture with enter
Material device is connected, and described discharging opening is connected with cement bunker, and described air inlet is connected with air, described air outlet with gather dust
Device is connected.
Airlock is provided with described charging aperture, described airlock is double-deck weight tilting plate lock wind discharge valve, institute
The feed arrangement stated is connected by airlock with the charging aperture of ball mill.
Described air inlet sets three, and one of air inlet is arranged on the end face of mill tail, two other air inlet
It is symmetrically arranged on the side of mill tail, three air inlets are arranged at the position below ball mill center line.
Described air inlet is provided with blinds valve.
Described air outlet is connected with plenum pulse cloth bag collector, described plenum pulse cloth bag collector and dust collecting fan phase
Even.
Described air outlet is connected with V-type gas flow sizing machine, and is set on pipeline between air outlet and V-type gas flow sizing machine
There is the first electric butterfly valve.
Described air outlet is connected with high-efficient powder concentrator, and pipeline between air outlet and high-efficient powder concentrator is provided with second
Electric butterfly valve.
As shown from the above technical solution, cement grinding system provided by the utility model, its supplied materials direction enters for bistrique,
Mill tail goes out, and its airflow direction enters for mill tail, and bistrique goes out, come quickly, significantly by way of this material and air-flow reverse movement
Reduce out the temperature inside the temperature and grinding machine of mill cement degree；While cooling, air-flow heats up because of heat absorption, so air-flow
It is just synchronous that drying course is completed to supplied materials heat release, discharged in time after the moisture content drying for being carried；Simultaneously can be according to supplied materials
Moisture content, operating mode in temperature and mill, the air quantity in any adjustment mill, reduces out the fineness of mill cement at any time, improves out Mo Shui
The specific surface area of mud, makes both qualification rates significantly rise.
