Problems solved by technology

In the existing process, the massive gypsum is generally made into powdery whiskers through the pulverizing equipment first, and then the whiskers are dried through the drying equipment. The pulverizing equipment and the drying equipment are set separately, which occupies a large area and is complicated to operate. Moreover, the milling process and the drying process are carried out separately, so multiple staff members are required to control them separately, which leads to the problems of low production efficiency and high production cost

Embodiment 1

[0045] Embodiment 1 discloses a milling and drying integrated machine, comprising: a feeder; a milling and drying chamber, which communicates with the feeder; a grinding roller, which is arranged in the milling and drying chamber and located The bottom of the communication port between the milling drying chamber and the feeder; the hot air blower, which communicates with the milling drying chamber, is used to deliver hot air to the milling drying chamber, and the communication port between the hot air blower and the milling drying chamber is located in the Below the grinding roller.

[0046] During use, the feeder transports the material to the milling and drying chamber, and the grinding roller rubs and breaks the material to obtain whiskers, and the hot air blower supplies hot air to the milling and drying chamber to dry the whiskers.

Embodiment 2

[0048] The difference between the second embodiment and the first embodiment is that the integrated grinding and drying machine in the second embodiment also includes an agitator, the agitator is arranged in the grinding and drying chamber, and is located under the grinding roller, and the agitator is used to stir the whiskers .

[0049] The agitator can drive the hot air entering the grinding and drying chamber to generate a high-speed rotating air flow, and then form a stable fluidized bed in the grinding and drying chamber below the grinding roller, avoiding local sticking of materials; secondly, the agitator is set on the grinding roller At the bottom, during the high-speed rotation process, the grinding roller continuously kneads the bulk material, and the material is crushed into fibrous powder whiskers, thereby increasing the surface area of ​​the material and strengthening the mass-heat exchange of the material. Then the agitator is continuously stirred, so that the dr...

Embodiment 3

[0053] The difference between the third embodiment and the second embodiment is that the integrated grinding and drying machine in the third embodiment also includes a cone structure. The first end of the cone is fixed at the bottom of the milling and drying chamber, and the second end is used to install the agitator, and the volume of the cone structure gradually decreases from the first end to the second end.

[0054] The setting of the cone structure makes the flow cross-sectional area of ​​the hot air in the powder milling and drying chamber continuously increase from bottom to top, the air velocity at the bottom is relatively large, and the air velocity at the upper part is relatively small, thus ensuring that the large particle whiskers at the lower part are in fluidization At the same time, the small particle whiskers on the upper part are also in a fluidized state; and installing the agitator on the cone structure can also shorten the length of the arm part of the agita...

Abstract

The invention discloses an all-in-one pulverizing and drying machine and a pulverizing system. The all-in-one pulverizing and drying machine comprises a feeder, a pulverizing and drying chamber, a grinding roll and a hot air blower, wherein the pulverizing and drying chamber is communicated with the feeder; the grinding mill is arranged in the pulverizing and drying chamber and is positioned below the communication opening of the pulverizing and drying chamber and the feeder; the hot air blower is communicated with the pulverizing and drying chamber, and is used for sending hot air into the pulverizing and drying chamber; the communication opening of the hot air blower and the pulverizing and drying chamber is positioned below the grinding roll; the feeder transports a material into the pulverizing and drying chamber; the grinding roll rubs and crushes the material to obtain whiskers; and the hot air blower sends hot air into the pulverizing and drying chamber to dry the whiskers. According to the all-in-one pulverizing and drying machine provided by the invention, the material can be pulverized and dried at the same time, the production efficiency is high, less operators are required, the production cost is reduced, the equipment size is small, the floor space is small, and the workshop space is saved.

Description

technical field [0001] The invention relates to the technical field of material preparation equipment, in particular to a milling and drying integrated machine and a pulverizing system. Background technique [0002] In the production process of non-metallic new materials, it is often necessary to make gypsum whiskers from block gypsum, and then apply the gypsum whiskers to the production of mixed new materials. In the existing process, the massive gypsum is generally made into powdery whiskers through the pulverizing equipment first, and then the whiskers are dried through the drying equipment. The pulverizing equipment and the drying equipment are set separately, which occupies a large area and is complicated to operate. Moreover, the milling process and the drying process are carried out separately, so a plurality of staff members are required to control them separately, which leads to the problems of low production efficiency and high production cost. [0003] Therefore,...
