Its mechanical structure is that the motor drives the eccentric shaft through a synchronous gearbox, and the eccentricity and eccentric mass are fixed. Therefore, when a certain value of excitation force is to be reached, it can only be achieved by requiring it to reach a certain speed, as the eccentricity and quality cannot be changed. When making bricks with a relatively small amount of concrete, the excitation force still has to maintain such a benchmark, because if the rotation speed is low, although the excitation force is also low, the frequency also decreases. The quality of concrete molding mainly depends on two factors, the excitation force and the vibration frequency. The frequency of vibration reaches more than 4000 rpm, which can make cement liquefy faster. That is to say, even when making some bricks with a relatively small amount of concrete, a relatively large excitation force must be used to obtain a relatively large vibration frequency (because the eccentricity and mas...

Introduction on Light Weight Foam concrete Plant The light weight foam concrete block is a kind of foaming agent that is fully foamed mechanically through the foaming system of the foaming machine, and the foam is uniformly mixed with the cement slurry, and then injected into the mold to be formed. It is formed by natural curing, a new type of lightweight thermal insulation material with a large number of closed pores. It is a bubble-shaped heat-insulating material, and its outstanding feature is that the closed foam cells are formed inside the concrete, so that the foamed concrete block can achieve the effect of light weight and thermal insulation.    The light weight foam concrete is prepared by directly adding hydrolyzed natural resin foaming agent to cement concrete or prefabricating a large amount of foam without adding perlite, polypropylene EPS beads and other materials. The main feature of this kind of foam is that its water absorption rate is less than 5%, no connect...

As China pays more and more attention to the protection of land resources and the protection of earthquake disasters, the demand for lightweight thermal insulation wall materials that can not only have the features of heat insulation, heat preservation, energy saving and emission reduction, but also effectively reduce the weight of the wall and resist earthquakes is also increasing. Self-heating EPS foam block (homogeneous) is one of the new energy-saving, light-weight and environmentally friendly building materials promoted in the world. The promotion and application of new wall materials to gradually replace solid clay bricks and other heavy wall material is an urgent need to improve resource utilization and protect the environment. On the other hand, the traditional construction industry is a large energy consumer and has always occupied the first place in the country's total energy consumption. According to relevant statistics, the energy consumption of buildings in ...
