Embodiment approach 2

[0089] Embodiment 2: The method and equipment for pressing the synthetic plate with the maximum size of 0.75M*3.1M:

[0090] In the embodiment of a pressing method and equipment for pressing granular aggregates into composite boards provided by the present invention, most of the structures of the equipment in this embodiment are the same as those in the first embodiment, the main difference is that, as image 3 and Figure 4 , the vibrating device 22 can be composed of 4 exciters. The power of each exciter is 20KW, the maximum excitation force is 180KN, and the maximum vibration frequency is 60Hz. 4 sets of exciters are arranged in two rows, and the rows of exciters are synchronized by synchronizers and rotated in opposite directions. The centrifugal forces in the horizontal direction generated by the two rows of exciters cancel each other out, and the centrifugal forces in the vertical direction are superimposed on each other, resulting in vertical orientation. vibration. ...

Embodiment approach 3

[0103] Embodiment 3: A pressing method and equipment for pressing a synthetic plate with a maximum size of 1.4M*3M, such as Figure 5 and Figure 6 As shown, most of the structures of the equipment in this embodiment are the same as those in Embodiment 1, the difference is that the vibration device 22 is composed of 8 mechanical vibration generators. The power of each mechanical vibration generator is 22KW, the maximum excitation force is 200KN, and the maximum vibration frequency is 60Hz.

[0104] In this example, the granular aggregate is a mixed aggregate of natural quartz stone granular aggregate, natural granite granular aggregate, shell granular aggregate and metal granular aggregate. -10 mesh granite particles, 6-8 mesh shell particle aggregates, 6-10 mesh metal particle aggregates, 6-20 mesh quartz stone particles, 20-40 mesh quartz stone particles, 40-70 mesh quartz stone particles, 400 mesh Quartz stone particles.

[0105] Thoroughly stir these granular aggregates...

Abstract

The invention relates to a method and equipment for pressing granulated aggregate into a synthetic plate. The method comprises the steps of material preparation, pavement and plate manufacture; and the method is characterized in that: in the plate manufacture step, each square meter of the granulated aggregate are vibrated by 240 to 450 kN exciting force in a vacuum state and are applied with pressure during vibration. In the technical scheme provided by the invention, the 240 to 450 kN exciting force is adopted to apply to each square meter of the granulated aggregate in the pressing process and granules with different sizes can be the pressed. The vibrating frequency is adjusted to make the granules have multidirectional movement, and optimal combination surfaces can be found among the granules for arrangement. The pressure is applied while the exciting force is applied; gaps among the granules are continuously compressed; in the pressure application process, the exciting force with the vibrating frequency can well control and guide the moving direction of the granulated aggregate to make geometric surfaces of the granulated aggregate occluded with each other.

Description

technical field [0001] The present invention relates to a method of pressing granular aggregates into composite panels and to equipment for carrying out the method. Background technique [0002] Pressing various granular aggregates into various thin plates has been widely used, especially in the construction material production industry, such as pressing ceramic tiles, pressing thin-slab synthetic stones, etc. [0003] For ceramic tile pressing, a large-tonnage hydraulic press is usually used to press the aggregate into shape with a pressure of thousands of tons or more. In the process of applying pressure, because the granular aggregates of tiles are very fine powdery particles, the friction between particles is very small. When the aggregate is under pressure, the particles can move to each other and shrink The gap, thus forming a tight profile. It is also such a pressing principle that leads to the use of raw materials for ceramic tiles, only fine powdery granular aggre...
