Problems solved by technology
[0003] In the production process, for the convenience of subsequent processing, the calcium carbonate needs to be crushed, and the calcium carbonate is processed into powder by the grinding device after crushing, but it is very easy to generate dust in the grinding device during the grinding process, and it is easy to leak into the In the atmosphere, the atmosphere is polluted, and, in the existing technology, grinding and drying are generally carried out separately, that is, first drying and then grinding, or first grinding and then drying, the processing process is troublesome, and the carbonic acid cannot be simultaneously Calcium is crushed, ground and dried

Embodiment 1
[0023] This implementation includes a housing 1, the housing 1 is provided with a feed port 101, and the bottom of the housing 1 is provided with a discharge port 102, and the feed port 101 is connected with a screw feeder 2. This embodiment also includes a cyclone separator 13 and a heater 14, the housing 1 is sequentially provided with a material guide plate 3, a first grinding sieve plate 4 and a second grinding sieve plate 5, which divide the inside of the housing 1 into four areas from top to bottom. The above four areas are sequentially from top to bottom the crushing area 6, the first grinding area 7, the second grinding area 8 and the storage area 9, the crushing area 6 is provided with a crushing device, and the first grinding area 7 is provided with The first grinding device, the second grinding area 8 is provided with a second grinding device 12, and the four areas are all communicated with the cyclone separator 13, and the cyclone separator 13 is connected with a he...
Embodiment 2
[0030] This embodiment is further optimized on the basis of Embodiment 1. In this embodiment, the connection position between the first grinding sieve plate 4 and the housing 1 is provided with a material return port, and the material guide plate 3 and the housing 1 The connection position is provided with a material return inlet, and the material return port and the material return inlet are connected through the first screw feeder.
[0031] Principle of the present invention is as follows:
[0032] First, feed through the screw feeder 2, and the calcium carbonate enters the crushing area 6 and is pulverized through the crushing device; then enters the first grinding area 7 and undergoes primary grinding through the first grinding device; then enters the second grinding area 8 undergoes secondary grinding through the second grinding device 12, and finally enters the material storage area 9 for storage; during the process from the material storage area 6 to the material storag...

Abstract
The invention discloses a grinding device for calcium carbonate powder. The grinding device comprises a casing, wherein a feeding inlet is arranged on the casing; and the feeding inlet is connected with a screw feeder. The grinding device is characterized by further comprising a cyclone separator and a heater. The casing is internally and sequentially provided with a guiding plate, a first grinding sieve plate and a second grinding sieve plate from top to bottom, and the guiding plate, the first guiding sieve plate and the second grinding sieve plate divide the interior of the casing into fourareas; the four areas sequentially include the smashing area, the first grinding area, the second grinding area and the storage area from up to down; the smashing area is internally provided with a smashing device; the first grinding area is provided with a first grinding device; the second grinding area is provided with a second grinding device; the four areas communicate with the cyclone separator; the cyclone separator is connected with the heater; and an outlet of the heater communicates with the four areas. The grinding device can smash and then grind calcium carbonate, dry the powder during grinding, and effectively prevent the dust in the grinding device from leaking.
Description
technical field [0001] The invention relates to the technical field of calcium carbonate crushing and grinding, in particular to a calcium carbonate powder grinding device. Background technique [0002] Calcium carbonate is an inorganic compound, commonly known as: limestone, limestone, stone powder, marble, etc., the main component: calcite, is a compound, neutral, basically insoluble in water, soluble in hydrochloric acid. It is a common substance on the earth. It exists in aragonite, calcite, chalk, limestone, marble, travertine and other rocks. It is also the main component of animal bones or shells. Calcium carbonate is an important building material and has a wide range of industrial uses. Calcium carbonate is formed by the combination of calcium ions and carbonate ions, so it is both calcium salt and carbonate. Among them, ultrafine ground calcium carbonate can be combined with modern polymer matrix composite materials, plastics, rubber, adhesives, paints, coatings, ...
