Product Description

Newly Researched and Designed cement Ball Mill Used in the Cement Making Plant

 

Advantage of our Cement Ball Mill:

 

Limestone Homogenization Silo: Simple device, economically, Little Floor Space

 

Considering the fact that difference exists in the ingredient content of limestone, which makes the quality

index difficult to control, the design uses the effective small-scale cross cut type raw material

prehomogenization storage (that is, vertical prehomogenization storage) to narrow standard deviation.

The homogenizing of the prehomogenization storage is 3~ 6 and discharges Ca-CO. The standard

deviation being about 1.5%~2.0%. It is especially fit for small dry-process cement plant whose capacity is

700t/d.

 

Low Power Consumption in Raw Material Homogenizing System

 

Considering limited spaces in the project site, we are going to engineer a φ15 ×35m MF homogenizing silo

is used to homogenize. Its effect volume is 5500t. The silo is made by the principle of gravity, so the power

consumption is as low as 0. 4 - 0. 6 kWh/t.

 

Convenient Feeding System

 

There 2 sets of mechanical feed weight scales are installed at the bottom of silos. Pulverized coal is fed

into the kiln head and decomposing furnace by rotary feeding device. The safe feeding system is easy to

control and running perfectly.

 

Cyclone System

 

In the design, the single row layout five-stage suspension preheater is used. Except for tube C1, others

are all low-pressure cyclones. Near feed points of cyclones air ducts, there are adjustable discharging

boards installed to help the material scattering, preventing the material from clustering drop and causing

short circuit.

 

The most Advanced RSP/F Decomposing Furnace

 

RSP/F decomposing furnace is developed on the basis of RSP technology, absorbing the advantages of

MFC furnace and adding the fluidized bed. It is composed of pre-combustion chamber, calcining chamber

and mixing chamber. RSP/F extends the standing time of pulverized coal and material. Due to the volume

of SC and MC is enlarged properly, and fluidized bed is added, standing time of pulverized coal and

material is extended to around 3.6s. The dispersiveness of material is intensified and it also enlarges the

heat transfer area of whole system.

 

Anti-blocking Measure of Preheating System

 

To prevent crusting and blocking problem, poking holes as well as air cannon are engineered in the flow

sheet; tricyclic compressed air purge system are installed in the C4-C5;there is bicyclic compressed air

purge system in C1-C2. To know the condition of preheater timely, there is also manometer to monitor the

working condition of cyclone. When the cementation blocking occurs, the monitoring device will release

alarm signal such as light or sound, and the operators can deal with it directly.
