With such volume of excavated and transported materials the conveyor belts (hereinafter referred to as CB) are damaged due to the impact of various negative factors.
Here we propose to install belt drifting sensors along the CB, as well as sensors of material clogging and a sensor of rotations.
· The second component would be represented by the sensor-based measuring systems for the measurements of physical parameters of the transported materials focused on the quality of material processing.

Therefore, applying the tailings to building materials is a sort of effective way to solve the comprehensive utilization of tailings.
The foam concrete with iron tailings is a new sort of building materials with light weight, high-strength, thermal insulation and fire prevention.
Further, the heat of hydration of cement-based materials could be absorbed by fiber.

Another reason for the continued investigation of these materials is their broad potential for everyday applications, such as magnetic refrigeration technology, absorbent devices, magnetoresistive random-access memory, sensors, and others, where the desired materials are capable of operating at room temperature and low magnetic fields [3–5].
Solid-State Method The precursor materials used were La2O3 (Merck), CaCO3 (Merck), SrCO3 (Sigma-Aldrich), and MnCO3 (Sigma-Aldrich) with high impurity.

Titanium dioxide also known as titania is a ceramic material.
Introduction There is a growing interest in the application of nano materials with an average grain size (1-50 nm) since their physical, chemical, magnetic, electronic and optoelectronic properties are quite unique and different from their bulk micron sized structures.
For instance, TiO2 is a semiconductor material with a wide variety of applications ranging from catalysis, sensors, memory devices and solar cells to cosmetics [1-4].

Preparation and Sizing Performance of the Modified Collagen Surface Sizing Agent WANG Xue Chuan1,a, HAO Xiao Li1,b, QIANG Tao Tao1,c 1Shaanxi University of Science and Technology, Key Laboratory of Chemistry and Technology for Light Chemical Industry, Ministry of Education, Xi’an, Shaanxi, China aemail: wxc-mail@163.com, bemail: haoxiaoli111@163.com, cemail: qiangtt515@163.com Key words: collagen, graft modification, sizing agent, preparation, sizing performance Abstract.
Using collagen as the raw material, methyl acrylate and vinyl acetate as the soft and hard monomers, ammonium persulfate as the initiator, a surface sizing agent was prepared by the emulsion polymerization method to modified the collagen.
Based on the above all, a surface sizing agent was prepared by the emulsion polymerization method to modified the collagen, using the collagen as the raw material, methyl acrylate and vinyl acetate as the soft and hard monomers, ammonium persulfate as the initiator.
It can be seen from the data of Table 1 that the sizing agent emulsion which was prepared by using the collagen with hydrolysis 2h as raw materials was the most stable and had not any layering or precipitate phenomenon.
