At present, 10 billion tons of industrial solid waste heap stock, which was used only about 50%, but also the remaining half of the solid waste of less than timely processing and utilization. Solid waste rate of 1 billion tons per year, polluting the ecological environment, affect the health of people’s lives, so the comprehensive utilization of industrial solid waste is imminent.
With the accelerated industrialization and urbanization process in China, industrial solid wastes produced upward trend year after year. The same time stimulate the further increase of the industrial areas of resource consumption; the supply of resources is increasingly tense.
The body of inertia cone crusher is located in the vibration isolation system. Set the shear elastic of vibration isolation system as K. the total mass of material in the crusher is M. the inertia force in any direction can be simplified as spring mass system by horizontal circular system. Because there is always hinder in the real vibration system, the free vibration force will decay with time growing, and the crusher is basically vibrate according to the vibrating regular of the second part.
The amplitude of crusher is infinity, which is known as resonance. When we choose vibration isolation system, we must make the natural frequency away from the frequency of inertial force to avoid the occurrence of resonance. The smaller the frequency the less force passed to the foundation. So, we should keep the frequency as small as necessary. With the certain mass of material in the crusher, we must use the spring with small shear elastic as vibration isolation elements.
Therefore, the aeration pulp during the flotation is called triphase system. While flotating, each mineral particle’s adhesive selectivity for the bubbles as well as their flotation behavior are determined by the physical and chemical property among the triphase boundary composed of mineral particle, water and bubbles. Among them, the wettability of the mineral surface is much more important. For instance, dropping a drop of water on a smooth and clean quartz surface, then the water drop expands quickly, that is to say the quartz can be wetted, it is hydrophilic; and again dropping the water drop on paraffin, the water drop remains a ball shape instead of spreading about, viz, paraffin is not that easy to be wetted by the water, so it is hydropobic. That is called wetting phenomenon. In order to increase the flotation machinery efficiency, the development of the new type machine has generally gained much more attention, especially in the recent decade, this machine is developing quite fast.
