Abstract
The present invention relates to a technology method for manufacturing inner burning type building gypsum. The present invention comprises the steps: material sorting and material crushing by a hammer crusher; lifting to a material discharge bin, and aging treatment; metering; lifting to a homogenizing bin again; homogenizing mix; providing of heat sources by a boiling surface; delivery of the materials to an inner burning type rotary furnace to be calcined; milling by a milling device; forming of finished products. The present invention has the advantages that raw materials of chemical gypsum and natural gypsum can be mixed, and can also be singly used; harmful impurities in the ardealite can be scorched at a high temperature in the using process of the chemical gypsum, cokes are formed, and the harmfulness is eliminated. The technology can remove the harmful impurities in the ardealite, can reutilize the chemical waste materials, and is a good waste utilization technique. A heat source system adopts the boiling furnace to burn coal, and has the characteristics of low coal consumption and low requirements for coal quality. The calcining system adopts the inner burning type rotary kiln, the heat efficiency is high and can achieve 49 to 61%, the heat efficiency is enhanced, the energy consumption and the labor intensity of workers are reduced, and the inner burning type rotary kiln has simple operation and easy control.
Description
Affiliated technical field
The present invention relates to a kind of inside burning type plaster of Paris manufacturing process.
Background technology
Along with the development of plaster of Paris industry, different forms has also appearred in the production technique of plaster of Paris.Burning formula rotary kiln outside the earliest frying pan develops into arrives fluidizing furnace again, and output is increasing, and specification of quality is more and more stricter.
Summary of the invention
In order to overcome the low shortcoming of existing outer burning formula rotary kiln method thermo-efficiency, the invention provides a kind of inside burning type plaster of Paris manufacturing process.The technical solution adopted for the present invention to solve the technical problems is: processing step is as follows:
Step 1: select materials, the compound that adopts the plaster of paris or chemical gypsum or the plaster of paris and chemical gypsum is as raw material; Fragmentation, with above-mentioned raw materials hammer crushing crusher machine, granularity is below 10mm;
Step 2: rise to storage bin, ageing is handled;
Step 3: metering;
Step 4: rise to the homogenizing storehouse again; Homogenizing is mixed;
Step 5: will send into the inside burning type calcined by rotary kiln through the gypsum material that step 4 is handled; Fluidizing furnace provides thermal source for the inside burning type calcined by rotary kiln;
Step 6: grinding, use the milling equipment grinding, granularity is more than 100 orders;
Step 7: finished product.
The invention has the beneficial effects as follows:
1, raw material can use the chemical gypsum and the plaster of paris to use with, also can use separately, and in the process of using chemical gypsum, can make the detrimental impurity high-temperature coking in the phosphogypsum, form coke, thereby remove its hazardness, this technology can be removed the detrimental impurity in the phosphogypsum, can carry out the utilization again of chemical waste, be a kind of reasonable utilization of waste material technology, its product stability is good, and cost is low.
2, heat source system adopts the fluidizing furnace fire coal, has that coal consumption is low, stable performance, ature of coal is required low characteristics.
3, calcination system adopts the inside burning type rotary kiln, and its thermo-efficiency is higher, can reach 49-61%.This technology has improved thermo-efficiency, has reduced energy consumption and labor strength, simple to operate, be easy to control.
4, grinding system adopts Raymond mill or ball mill, and abrasive dust is effective, efficient is high, energy consumption is low.
