Clay screening and crushing integrated equipment

Abstract

The invention clay screening and crushing integrated equipment. The clay screening and crushing integrated equipment comprises a sealed shell and is characterized in that the upper portion of the shell is provided with a feed inlet, the upper portion of the shell is provided with a discharge outlet, a pre-screen plate which connects the feed inlet and the inlet of a cyclone crushing device and isused for screening small-particle clay materials smaller than screen holes, a material conveying device used for conveying the screened and crushed materials into the discharge outlet is arranged under the pre-screen plate, and the outlet of the cyclone crushing device is arranged right above the material conveying device through a screen. The clay screening and crushing integrated equipment has the advantages that clay of different particle sizes can be crushed, high crushing efficiency, low energy consumption and small discharged material particle size can be achieved, and secondary pollution is reduced by an independent flying dust capturing and treating system.

Description

technical field [0001] The invention relates to an integrated clay screening and crushing equipment. technical background [0002] Clay, also known as clay, is a kind of soil with very small particles and strong plasticity, and its main component is aluminosilicate. In addition to aluminum, clay also contains a small amount of magnesium, iron, sodium, potassium and calcium, which is an important mineral raw material. Due to the high plasticity index of clay, the fracture deformation of clay itself is very different from that of hard materials (especially for those with high plasticity index. Viscous materials), it is difficult to achieve its optimal deformation speed by impact crushing, and most of the impact kinetic energy is absorbed by the external deformation of clay, resulting in extremely poor crushing effect. For clay materials, due to their obvious plastic deformation, it is more reasonable to use cutting and crushing methods to deal with them. In addition, for cla...

Problems solved by technology

[0003] The traditional clay screening and crushing process currently has the following problems: 1) Traditional soil screening and crushing equipment has low screening efficiency, low crushing efficiency, easy to block materials, and has strict requirements on the particle size of materials; 2) The equipment is easy to wear and tear, such as the crushing tool is easy to wear, and the particle size of the pellets is not easy to adjust and control, and the later inspection and maintenance are frequent; 3) The process of material screening and crushing is easy to generate a large amount of dust. Conventional screening and crushing equipment is sealed In terms of performance, the control and treatment of dust can hardly be achieved, and it is easy to cause serious pollution to the surrounding environment
