Embodiment 1

[0058] This embodiment provides a coal slime drying and crushing device, see Figure 1 to Figure 5 , including a feeder 1, a primary vibrating screen 2, a crusher 4 (for example, an impact crusher) and a secondary vibrating screen 3 arranged in sequence, and heat carrier gas (such as , hot air), the primary vibrating screen 2 is used for primary drying of coal slime, the crusher 4 is used for primary crushing of coal slime, and the secondary vibrating screen 3 is used for secondary drying and secondary crushing of coal slime. The discharge port of machine 1 is connected with the feed port of primary vibrating screen 2, the discharge port of primary vibrating screen 2 is connected with the feed port of crusher 4, the discharge port of crusher 4 is connected with the feed port of secondary vibrating screen 3 Feed port connection.

[0059] During implementation, the large-grained coal slime enters the feeder 1, and evenly enters the primary vibrating screen 2 from the feeder 1 u...

Embodiment 2

[0088] This embodiment provides a method for drying and crushing coal slime, comprising the following steps:

[0089] Step S1: using a primary vibrating sieve to dry the coal slime once to obtain a primary dried coal slime;

[0090] Step S2: Using a crusher to crush the primary dried coal slime to obtain the primary crushed coal slime;

[0091] Step S3: performing secondary drying and secondary crushing on the primary crushed coal slime by using a secondary vibrating screen to obtain a coal slime product.

[0092] Compared with the prior art, the beneficial effects of the coal slime drying and crushing method provided in this embodiment are basically the same as those of the coal slime drying and crushing device provided in Embodiment 1, and will not be repeated here.

[0093] In order to utilize the waste heat of the hot carrier gas, the above method also includes the following steps: circulating the hot carrier gas discharged from the secondary vibrating screen to the prima...

Abstract

The application discloses a coal slime drying and crushing device and drying and crushing method, which belong to the technical field of coal slime drying in coal preparation plants, and solve the problems of flammability, relatively low drying efficiency and the existence of "clumps" in coal slime drying and crushing in the prior art. The problem of the "ball" phenomenon. The device of the present application includes a feeder, a primary vibrating screen, a crusher and a secondary vibrating screen arranged in sequence. The primary vibrating screen and the secondary vibrating screen are fed with heat carrier gas, and the primary vibrating screen is used for the primary drying of the coal slime. The crusher is used for primary crushing of coal slime, and the secondary vibrating screen is used for secondary drying and secondary crushing of coal slime. The method of the present application includes two times of drying and two times of crushing. The coal slime drying and crushing device and the coal slime drying and crushing method of the present application can be used for drying and crushing of coal slime.

Description

technical field [0001] The application belongs to the technical field of coal slime drying in coal preparation plants, and in particular relates to a coal slime drying and crushing device and a drying and crushing method. Background technique [0002] With the rapid development of the depth and breadth of coal processing, the output of coal slime has increased significantly. Because coal slime has the characteristics of strong water holding capacity, high moisture content, high viscosity, high ash content, and low calorific value, it is difficult to realize industrial application. Low. [0003] Coal slime can be used for remixing or power supply after drying, which has environmental and economic benefits. Coal slime drying is becoming a necessary prerequisite for large-scale utilization of coal slime, and has gradually become a hot spot in the industry. Existing coal slime is flammable when dried and broken, and the drying efficiency is relatively low. The slime of some c...
