Problems solved by technology

But this method bentonite needs calcium base bentonite raw ore to be pulverized to the powder of particle diameter<2mm before acidification treatment, and this is difficult to realize in industrial production; Sodium hydroxide is strongly corrosive, and sodium fluoride is toxic to a certain extent. If cat litter containing these two substances is used for a long time, it will have a certain impact on the health of cats.

Embodiment Construction

[0023] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.

[0024] See figure 1 A kind of preparation method of bentonite cat litter, comprises following process step and process parameter:

[0025] 1. Dry and remove impurities. The calcium-based bentonite raw ore is placed in the cement drying yard for drying. During the drying process, manual hand selection is carried out to remove impurities. After drying, the moisture content of the raw ore is ≤ 22%.

[0026] 2. Crushing and sorting. The raw ore after drying is crushed by a hammer crusher, and then the ore with a particle size of ≤25mm is selected by drum screening for future use.

[0027] 3. Sodium modification. Transport the mineral material to the wheel mill, add sodium carbonate powder with a mass of 1.5%~2.0% of the mineral material and mix for 1-2 minutes, then add an appropriate amount of water to control the water content at 22%~23%, and wheel ...

Abstract

The invention discloses a preparation method and device of bentonite cat litter. The preparation method consists of airing, crushing, sodium-treating, drying, screening and packaging. The device consists of a hammer crusher, a trommel screen, a planet gear mill, a roller drier and a belt conveyor. The raw ore of bentonite is subject to simple airing and manual impurities removal, is crushed and subject to sodium-treatment modification by using the planet gear mill, and is dried and screened to obtain the bentonite cat litter finished product. By adopting the method, grinding and granulating processes required by the conventional method for preparing the bentonite cat litter are saved, the consumption of a sodium-treating agent is less, the process is simple, and the cost is low.

Description

technical field [0001] The invention relates to a production technology of bentonite cat litter, in particular to a method for preparing bentonite cat litter from pure natural calcium-based bentonite through sodium modification. Background technique [0002] With the improvement of human living standards, the number of pets such as cats and dogs raised by families is also increasing day by day, and the treatment of pet excrement also plagues most families who keep pets. The research on the application of bentonite to cat litter began in the United States in 1947. However, due to technical limitations, there are various problems in bentonite cat litter, such as large dust and low agglomeration strength. With the development of industry and the increase of investment in research, the quality of bentonite cat litter products has been greatly improved. [0003] There are many domestic enterprises that produce bentonite cat litter, most of which use traditional production method...
