Description

Technical Field

[0001] The utility model relates to the technical field of mining processing equipment, in particular to a pulverizer for kaolin processing with a filtering structure. Background Art

[0002] Kaolin is a non-metallic mineral, a clay and clay rock mainly composed of kaolinite clay minerals. Kaolin is white, fine, soft and soil-like, with good physical and chemical properties such as plasticity and refractoriness. Its mineral composition is mainly composed of kaolinite, halloysite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals. Kaolin is widely used, mainly for papermaking, ceramics and refractory materials, enamel glaze and white cement raw materials. Kaolin is in a block structure before it is finished, and it needs to be crushed into powder by a pulverizer before it can be used. However, the existing kaolin pulverizer usually adopts a pulverizer of ordinary structure, which has a simple structure, single-layer pulverization, poor pulverization effect, and can only pulverize kaolin, and cannot filter, resulting in many impurities when discharging, which cannot meet production needs well. In view of this, the inventor proposes a pulverizer for kaolin processing with a filtering structure to solve this problem, which adopts two pulverizations and is provided with a filter screen to achieve better pulverization and filtering effects.

[0003] In order to screen the crushed kaolin and improve the quality of the crushed kaolin, a Chinese patent (authorization announcement number: CN213966837U) discloses a pulverizer for kaolin processing with a screening structure. The utility model includes a pulverizer housing and a conveying pipe. The inner sides of the pulverizer housing are provided with a slide, an L-shaped iron block and a spring from top to bottom, and a mesh screen is fixed to the outside of the spring. A vibrator is installed below the mesh screen. The outer front end of the pulverizer housing is connected to the cover plate through a hinge, and a bolt is provided at the front end of the cover plate. A motor is installed above the L-shaped iron block, and a small gear is provided at the front end of the motor, and a medium gear is provided outside the small gear. The utility model can screen the crushed kaolin, and can screen the kaolin that meets the crushing standards and the kaolin that does not meet the crushing standards, so that the staff can perform secondary processing and crushing on the kaolin that does not meet the standards.

[0004] This solution still has some shortcomings in application. Since the finished kaolin product is in a mineral stone state before, the crushing effect cannot be achieved well by only one crushing. Some small particles will fall from the gap of the crushing shaft, resulting in poor crushing effect, which in turn affects the filtering and discharging. Therefore, it is necessary to improve the structure of the crusher so that it can achieve double crushing and improve the crushing quality, thereby improving the production efficiency and quality of kaolin.

[0028] [Embodiment]

[0029] First, kaolin ore enters the crushing device 1 from the feeding hopper 10 and is crushed by the crushing roller 11. Since the outer side wall of the crushing roller 11 is provided with engaging convex teeth 111, the kaolin ore can be crushed into particles or powder and enter the first vibrating screen 3. Then, primary screening is carried out through the first vibrating screen 3. The kaolin passing through the first vibrating screen 4 enters the feeding cavity 2. Then, the kaolin in the feeding cavity 2 is stirred by the stirring roller 7 driving the stirring blade 71 to prevent the kaolin from caking and squeezing, which affects the secondary screening. At the same time, the second vibrating screen 4 performs secondary screening and filtration on the kaolin in the feeding cavity 2, so that the qualified kaolin finally falls into the discharge hopper 9 for unified material collection. At the same time, the waste on the first vibrating screen 3 and the second vibrating screen 4 can be collected through the first material taking port 15 and the second material taking port 16 for secondary processing.
