Embodiment 1

[0025] see Figure 1-3 , a pulverizer, comprising a casing 1 and a rotating shaft 2, the rotating shaft 2 extends into the casing 1, the rotating shaft 2 is connected to a motor 10 through a crawler belt 3, a detachable round cover 6 is arranged on the side wall of the casing 1, The middle part of the round cover 6 is provided with a feed inlet 4, and the bottom of the casing 1 is opened to form a discharge outlet 5, and the casing 1 is provided with a turntable I11 and a turntable II12. There are two rotating shafts 2, namely the concentric rotating shaft I21 and the rotating shaft II22. The rotating shaft I21 is hollow, and the rotating shaft II22 passes through the rotating shaft I21 and is exposed at both ends. The turntable I11 and the turntable II12 are respectively connected to the rotating shaft I21 and the rotating shaft II22, and a plurality of rolls 13 are arranged at the edges of the turntable I11 and the turntable II12. The rolls 13 on the turntable I11 and the t...

Embodiment 2

[0031] see Figure 4 and Figure 5 , the rotating shaft I21 and the rotating shaft II22 are arranged on both sides of the casing 1, and the diameter of the rotating disk II12 is smaller than that of the rotating disk I11. Compared with the overlapping design of double rotating shafts in embodiment 1, the two rotating shafts in this embodiment adopt a symmetrical structure, which can save space, while the symmetrical distribution of double rotating shafts has a relatively simple structure and is easy to maintain. Other parts of this embodiment are the same as in Embodiment 1, and the working principle is also the same.

Abstract

The invention discloses a grinder which is particularly suitable for grinding shale and coal gangues. An existing grinder can perform grinding in a manner of knocking by a mechanical part and the uniform grinding is difficultly guaranteed by the knocking manner; the mechanical part is very easy to abrade. The grinder comprises an enclosure and rotary shafts; the rotary shafts stretch into the enclosure; the enclosure is internally provided with a rotary table I and a rotary table II; two rotary shafts are arranged and respectively comprise a rotary shaft I and a rotary shaft II; the rotary table I and the rotary table II are respectively connected with the rotary shaft I and the rotary shaft II; the edges of the rotary table I and the rotary table II are provided with a plurality of rollers. The rollers are rotated to further drive raw materials entering the enclosure to rotate so that the raw materials are collided and grinded with one another; not only can the grinding effect be uniform, but also the mechanical part is hard to abrade.

Description

【Technical field】 [0001] The invention relates to the technical field of pulverizers, and is particularly suitable for pulverizing coal gangue and shale. 【Background technique】 [0002] Coal gangue and shale are important raw materials for making building materials such as hollow bricks. These raw materials must first be crushed before they can be used. Existing pulverizers are mostly hammer-type, as disclosed in the Chinese invention patent with the application number 02268617.7, comprising a casing, the casing is provided with a feed inlet and a discharge outlet, and a crushing chamber is provided in the casing , The hammer mill smashes the raw materials passing through the crushing chamber by rotating the hammer head set in the casing. In the crushing process of this hammer mill, the hammer head is easily worn during the knocking process, and it is difficult to ensure uniform crushing during knocking, so that the raw materials obtained from the discharge port have coarse...
