Embodiment 1

[0061] In order to verify the feasibility of the production process and facilities of the present invention, the applicant has specially built a test kiln. The structure of the test kiln is shown in figure 1 . The device for implementing the method for producing highly active mineral materials includes a vertical cylinder calciner 1, a combustion furnace 2, a dust collector 3, an induced draft fan 4, and a temperature measuring instrument 5. The top of the vertical cylinder calciner is provided with a feed port 6, and the vertical cylinder The bottom of the calciner 1 communicates with the combustion furnace 2 ; the vertical tube calciner 1 is provided with a preheating pipe 7 , and the preheating pipe 7 extends into the combustion furnace 2 .

[0062] Mineral raw materials are pulverized to obtain mineral powder. The mineral powder enters the vertical calciner 1 through the feed port 6. During the sinking process, the mineral powder is fully preheated by the preheating pipe 7...

Embodiment 2

[0089] figure 2 It is a schematic diagram of another device for implementing the method for producing highly active mineral materials provided by the embodiment of the present invention. From figure 2 It can be seen that the device includes a vertical calciner 1, a combustion furnace 2, a dust collector, an induced draft fan 4, a silo 10, a meter 9, and a discharger 8;

[0090] Wherein, the silo 10 is connected with the meter 9, and the unloader 8 is connected with the feed port, and the meter 9 is used to control the amount of the mineral powder in the silo 10 entering the unloader 8. Mineral raw materials are crushed by a crusher and ground to a specified fineness by a pulverizer to obtain mineral powder. The mineral powder is transported to the silo by the elevator, and then transported to the unloader 8 by the meter 9 (such as a spiral metering reamer). (such as the air lock valve), and then the mineral powder enters the vertical calciner 1 through the feed port. Duri...

Abstract

The invention relates to the field of material processing, and especially relates to a method and a device used for preparing a high-activity mineral material. The method comprises following steps: a mineral raw material is grinded into mineral powder with a particle size less than 200<mu>m; the mineral powder is calcined, and is cooled to as to obtain the high-activity mineral material. According to the method, grinding is adopted firstly, and calcining is adopted later, the mineral raw material is grinded until particle size is less than 200<mu>m, and then is subjected to calcining; powder particles are fine, so that calcining time can be shortened greatly, thermal efficiency is increased, unit volume yield is increased greatly, calcining quality is improved, the obtained high-activity mineral material is high in activity coefficient, low in water requirement, excellent in appearance colour, and high in particle sphericility. It is confirmed by experiments that product performance is better than that of second class powered coal ash, and application prospect is promising. The disclosed corresponding device is capable of satisfying production requirements preferably.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a method and device for producing highly active mineral materials. Background technique [0002] The use of coal ore, shale and other mineral raw materials to produce highly active mineral materials has a long history, and predecessors have done a lot of research on this, but so far, no efficient production process and facilities have been researched and developed. Most of them are produced in a simple way; there are roughly two production methods at present, one is the open-air pile firing method, and the other is the use of shaft kiln calcination. Both methods have the problems of poor firing quality and low production efficiency. . [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The first object of the present invention is to provide a method for producing highly active mineral materials. This method aims at the shortcoming...
