Coal gangue, ardealite and sludge ceramsite production equipment and production process thereof

Abstract

The invention relates to the technical field of coal gangue ceramsite production equipment, in particular to coal gangue, ardealite and sludge ceramsite production equipment and a production process thereof. The equipment comprises a base, a sludge pump, an electric push rod, a first servo motor, a second servo motor, a third servo motor and a steam heater; a mixing tank is fixedly installed aboveone end of the base; a material transportation pipe fixedly communicates with the left side of the top of the mixing tank; a first rotary shaft is arranged at the central position inside the mixing tank in a horizontally inserting mode; and spiral vanes are fixedly installed on the left side outer wall of the first rotary shaft. Sludge, coal gangue and ardealite are organically combined as raw materials, are dehydrated after mixing, are subjected to drying processing, are then subjected to pelleting in a pelletizer, and are subjected to fire molding in a rotary kiln. The equipment and the process are beneficial to utilizing the sludge and coal gangue waste to generate beneficial values, is beneficial to lowering cost and consumption in environmental governance, and is convenient for realizing sustainable development of resources.

Description

technical field [0001] The invention relates to the technical field of coal gangue ceramsite production equipment, in particular to coal gangue, phosphogypsum and sludge ceramsite production equipment and a production process thereof. Background technique [0002] Ceramsite is a kind of granular material made of pottery, which has the properties of low density, high cylinder compressive strength, high porosity, high softening coefficient, good frost resistance, and excellent anti-alkali aggregate reactivity. Due to its low density, internal porosity, uniform shape and composition, and certain strength and firmness, ceramsite has multifunctional characteristics such as light weight, corrosion resistance, frost resistance, shock resistance and good insulation, making it applicable in Various industrial and civil construction fields, so it has high production value. In the prior art, ceramsite can be processed by earth and stone waste particles in a rotary kiln; [0003] In re...
