Problems solved by technology
[0009] After roasting, the internal structure of the spherical ceramsite is tighter. Although the strength of the spherical ceramsite is relatively high, the effective specific surface area is small, and the specific gravity and bulk density are relatively large, thereby reducing the adsorption capacity and water absorption of the spherical ceramsite.

Embodiment Construction
[0045] Below in conjunction with embodiment the present invention will be further described:
[0046] 1. The ingredients of vermiculite light through-hole ceramsite are composed of the following components by weight percentage: 28% of expanded vermiculite, 26% of high-viscosity attapulgite clay, 8% of powdery attapulgite foaming agent, and 5% of activated clay waste residue %, floating beads 4%, light magnesium oxide 3%, expanded perlite 1%, ferrous sulfate 1% and water 24%.
[0047] 2. The production method of vermiculite light through-hole ceramsite: (1) Input the ingredients of vermiculite light through-hole ceramsite into the stirring mixer that has been running, and stir and mix it into a mixture of vermiculite light through-hole ceramsite; (2) Transport the mixture of vermiculite light through-hole ceramsite to the extrusion granulator, and extrude and granulate it into vermiculite light through-hole ceramsite semi-finished products of different shapes; (3) vermiculite l...

Abstract
The invention discloses light and through-hole ceramsite containing vermiculite. The light and through-hole ceramsite containing vermiculite is characterized in that the light and through-hole ceramsite containing vermiculite consists of expanded vermiculite, high-viscosity attapulgite clay, powdery attapulgite foaming agent, activated clay waste residue, floating beads, light magnesium oxide, expanded perlite and ferrous sulfate. The light and through-hole ceramsite containing vermiculite is prepared by stirring and mixing materials of the light and through-hole ceramsite containing vermiculite, extruding, granulating, drying, roasting, insulating, screening, sealing and packaging. The light and through-hole ceramsite containing vermiculite has the advantages of large specific surface area, low stacking density, high water absorption rate, excellent air permeability, beautiful appearance and modeling, no objectional odor, light weight, good strength and integration of small holes and large holes. When the light and through-hole ceramsite containing vermiculite is used for culturing or planting various nursery-grown plants, flowers, grasses and vegetables, the roots of the plants can absorb water or nutritional ingredients of liquid fertilizer from the light and through-hole ceramsite containing vermiculite, so that good growth and development and high survival rate of the plants are ensured. The light and through-hole ceramsite containing vermiculite is applicable to preparing of soilless culture substrates and nutritional soil.
Description
technical field [0001] The invention relates to ceramsite, in particular to a vermiculite lightweight through-hole ceramsite. Background technique [0002] The soil used for cultivating or planting various seedlings, flowers and vegetables is mostly made of nearby soil, and then mixed with some plant ash or peat soil. The moisture content of these soils is 12-20%, and contains a large amount of harmful bacteria. [0003] When using these soils to cultivate or plant various seedlings, flowers and vegetables, it is difficult to control the amount of water in the later stage. After water replenishment, the soil moisture content exceeds 30%, and the moisture content in the soil is relatively high, and the soil will be semi-fluid. If the soil is not replenished in time, the soil will appear compacted and hard, which will directly affect the normal growth of plants. [0004] With the continuous improvement of the quality requirements of greening projects, materials such as fly a...
