Introduction
Data Mining (Data Mining) generally speaking is digging out from a number of data knowledge.
The main purpose of data mining is to identify trends and patterns in the data.
Broad -based knowledge discovery -oriented approach to reduction properties, for example, the method in the database by collecting the relevant data sets, followed by application of a series of data to promote technology, involving the concept of tree improvement, property removed attribute threshold control, and other aggregate functions dissemination.
Database Data Warehouse Data Mining Mode Knowledge Fig. 1, Data mining process As we can be seen from Figure 1 the data mining techniques basic process.
Conversion data Data conversion purpose is to convert the data type and value of the source data into a unified format, such as converting a Boolean type to integer ; converting continuous data into discrete types.

Fig.2 was the X-ray diffraction graph of the reduction products of copper slag.
Fig. 1 XRD of copper slag before reduction Fig. 2 XRD of reduction products 3.5 Thermodynamic analysis of the modification of slag and reduction The addition of CaO or lime could tend to increase the reduction ration of iron.
Which guaranteed the reduction process go with a swing.

Effect of Argillites Reduction Ratio on Ceramic Tile and Paving Clinker of Low-Temperature Sintering
A.V.
In given intervals of reduction ratio and firing temperature the index of water absorption capacity of less than 5 % needed for ceramic tile is achieved by size reduction of 0 – 0.315 mm and firing temperature of 1000 °C and higher.
For Vladimirovskoye deposit in given intervals of reduction ratio and firing temperature the index of water absorption of 5 % is achieved by size reduction of 0-0.315 mm and firing temperature of 1050 °C and higher.
Considering that laboratory data, in principle, don`t entirely have to focus on upper limit values, we can use an average index of water absorption capacity of 1.5 % for paving clinker and 3.5 % for ceramic tile.
In this case, the necessary indexes are achieved at higher firing temperatures and finer reduction ratio of the raw material.

The Kalman filter can be applied to remove noise or artifacts without affecting other crucial data [12] [13].
Numerical data analysis and computation are done with this application.
The Kalman filter is used to eliminate distortions and noise from a signal without compromising other crucial data.
The Kalman filter is capable of foretelling and examining relationships between various sorts of data.

Although the mass of the impacters is same, the vibration reduction effect is not obviously as the impacters diameter changes.
The aluminum filling rate is 40%, the impacters’ mass are same, but the vibration reduction effect is absolutely different.
