Embodiment 1

[0025] Embodiment 1: as attached Figure 1-5 As shown, a kind of equipment for dry purification of montmorillonite from high-grade bentonite ore includes an equipment mounting base 3, and a bentonite material crushing device 1 and a drive motor 2 are fixedly installed on the equipment mounting base 3, and the drive motor 2 and Bentonite material crushing device 1 transmission connection, described bentonite material crushing device 1 comprises crushing device shell 17, propulsion shaft 20, spiral crushing knife 21, crushing reamer 22, barrel wall reamer 19 and air-sent material cover 15, and the wind sends The material cover 15 is connected with an air supply purification system, the propulsion shaft 20 is rotated and placed in the shell 17 of the crushing device through a bearing 27, the spiral crushing knife 21 and the crushing reamer 22 are fixedly installed on the propulsion shaft 20 in sequence, and the barrel The wall reamer 19 is arranged on the inner wall of the crushi...

Embodiment 2

[0031] Embodiment 2: a kind of production technology of high-grade bentonite ore dry purification montmorillonite, adopts the equipment processing of above-mentioned high-grade bentonite ore dry purification montmorillonite, comprises the following operation steps:

[0032] S1: First, start the drive motor 2, the air blower motor 11 and the vibration motor 34, the drive motor 2 drives the bentonite material crushing device 1 through the drive belt 13, the motor drive turntable 14 and the crushing device drive turntable 12, and the bentonite raw material is fed through the raw material The bucket 10 is put into the bentonite material crushing device 1, and the propulsion shaft 20 rotating inside drives the spiral crushing knife 21 to rotate. The spiral crushing knife 21 initially crushes the larger bentonite block and drives the raw material to the direction of the crushing reamer 22. The crushed bentonite raw material enters the crushing gap between the crushing reamer 22 and t...

Abstract

The invention provides equipment for purifying montmorillonite from high-grade bentonite ore through a dry method. The equipment comprises a bentonite material crushing device, the bentonite material crushing device comprises a spiral crushing cutter, a crushing reamer, a barrel wall reamer and a wind-conveying discharging cover, the wind-conveying discharging cover is connected with an wind-conveying purification system, the spiral crushing cutter and the crushing reamer are sequentially and fixedly installed, the barrel wall reamer is arranged on the inner wall of a crushing device shell, the crushing reamer and the barrel wall reamer are arranged in a matched mode to form a crushing gap, the lower wall, located between the spiral crushing cutter and the crushing reamer, of the crushing device shell is provided with an impurity discharging opening, and an impurity separation baffle is arranged on one side, facing a raw material feeding hole, of the impurity discharging opening. The equipment adopts a secondary purification method, impurities are synchronously removed in the crushing process of bentonite ores, the advantages of high machining speed, simple process and good purification effect are realized, and the problem of high energy consumption due to the need for additives, large amounts of industrial water, and heating is solved.

Description

technical field [0001] The invention relates to the technical field of dry purification, in particular to equipment for dry purification of montmorillonite from high-grade bentonite ore and a production process thereof. Background technique [0002] At present, the process of purifying montmorillonite with bentonite all adopts wet process. The wet process is to roughly crush the high-grade bentonite ore, then disperse it in water to form a 10% slurry, add an appropriate amount of sodium hexametaphosphate dispersant and heat it to 95 degrees. The montmorillonite is dispersed in water, and the impurities other than the montmorillonite are precipitated. The montmorillonite aqueous solution is press-filtered, dehydrated, dried and pulverized into feed grade montmorillonite powder. The current technical solution requires a large amount of industrial water, and needs to add a dispersant, and needs to be heated to form a montmorillonite suspension. After purification, it needs to...
