Problems solved by technology

[0002] At present, the production process of ceramsite sand on the market has the following disadvantages: ①The process flow is discontinuous, and the amount of labor is relatively large; ②Due to the large number of joints in the link, the amount of dust in the process section is large, which is neither environmentally friendly nor energy-saving; ③Doping in manual powder mixing There are many human factors, which can easily cause the deviation or imbalance of the formula ratio; ④ use a forced mixer to mix the powder, the mineral powder and additives are mixed unevenly, resulting in poor roundness, sphericity and surface finish of the ceramsite product, which directly affects the ceramsite. Performance indicators, which in turn affect the effect of fracturing in oil and gas fields; ⑤ Only low-end products can be produced, and the economic and social benefits are very low

Embodiment

[0039] Example: see figure 1 , a fully automatic production method for ceramsite sand, its specific production process steps are as follows:

[0040] (1) Mineral processing: determine ore grade and ore source fixed point,

[0041] Among them, the content requirements of various ores are as follows:

[0042] Raw bauxite ore: Al 2 o 3 : 65%~75%; SiO2: 5%~14%;

[0043] Cooked bauxite ore: Al 2 o 3 : 80% ~ 86%; SiO2: 5% ~ 10%;

[0044] Mineralizer: MnO 2 : 55%~68%;

[0045] (2) After the primary and secondary crushing of different ores, they are sent to the raw material warehouse by the conveying equipment for use. Among them, the primary crushing: the original ore of about 400mm is crushed into 40mm ~ 50mm; the secondary crushing: after After the primary crushing, it will be crushed into 8mm~15mm;

[0046] (3) After the different ores and mineralizers in the raw material warehouse are measured by the computer automatic batching system at the bottom of the warehouse, the...

Abstract

The invention discloses a full-automatic production method of ceramsite sand. The method comprises the following steps of: determining the ore grade and ore source point; carrying out primary crushing and secondary crushing on different ores, and conveying the crushed ores into a raw material storehouse for use by a conveying device; metering the different ores and the mineralizer by a microcomputer automatic batching system at the bottom of a storehouse and putting in a ball mill for co-grinding, and storing the mixed powder in a powdery material storehouse for use; conveying the mixed powder in the powdery material storehouse to a pelletizing section by a spiral conveyor and respectively distributing to each pelletizer to pelletize, and screening the obtained raw pellets by a screening machine and storing for use; after drying the semi-finished raw pellets, conveying the dry pellets into a rotary kiln by a metering conveying device to calcine at high temperature; after screening thecalcined finished product of ceramsite sand, packing the ceramsite sand by an automatic weighing packing machine, testing and storing for sales. The ceramsite sand produced by the method provided by the invention is uniform in grain size distribution, radically overcomes the problems of bad roundness, bad sphericity and bad surface smoothness of ceramsite grains produced by the old process, enhances performance indexes of ceramsite, and greatly promotes the exploitation efficiency of oil and gas.

Description

1. Technical field: [0001] The invention relates to a production method of ceramsite sand, in particular to a fully automatic production method of ceramsite sand. 2. Background technology: [0002] At present, the production process of ceramsite sand on the market has the following disadvantages: ①The process flow is discontinuous, and the amount of labor is relatively large; ②Due to the large number of joints in the link, the amount of dust in the process section is large, which is neither environmentally friendly nor energy-saving; ③Doping in manual powder mixing There are many human factors, which can easily cause the deviation or imbalance of the formula ratio; ④ use a forced mixer to mix the powder, the mineral powder and additives are mixed unevenly, resulting in poor roundness, sphericity and surface finish of the ceramsite product, which directly affects the ceramsite. Performance indicators, which in turn affect the effect of fracturing in oil and gas fields; ⑤ ...
