Problems solved by technology

Because this method does not classify the material after ball milling, the particle size of the product is not uniform enough; and the existing dry ball mill directly discharges the material from the discharge port, which has a negative impact on the airtightness of the negative pressure feed. influences

Embodiment Construction

[0019] Combine below figure 1 , figure 2 and image 3 Introduce the present invention in detail:

[0020] The ultra-fine dynamic classification discharge device of the dry ball mill system comprises a hollow cylinder 3 with a discharge port 34 at the bottom, and a feed pipe 31 for the material to enter the inner cavity of the cylinder is provided on the upper part of the cylinder. The present invention The material is not limited to the material after ball milling, raw material powder can also be used; the lower part of the cylinder is provided with an air inlet pipe 32 for the gas to enter the inner cavity of the cylinder, and the negative pressure device arranged at the top of the cylinder makes the outside air flow from the The air inlet pipe 32 enters the inner cavity of the cylinder, and the gas entering the inner cavity of the cylinder blows the lighter materials in the inner cavity from bottom to top to the top of the cylinder and then flows out, and the heavier mate...

Abstract

The invention relates to a dry type ball-milling system and particularly relates to a superfine dynamic graded discharge device for a dry type ball-milling system. The device comprises a hollow cylinder with a discharge port at the bottom end. The discharge port is connected to a discharge mechanism, and materials flowing from the discharge port of the cylinder flow out through the discharge mechanism; the discharge mechanism comprises a base body which is hermetically connected to the discharge port and a discharge wheel which is arranged in the base body and is driven by a motor to rotate, and the materials flowing into the base body from the discharge port are driven by the discharge wheel which rotates to flow out. According to the device provided by the invention, outside gas is inhaled into the graded cylinder by using a negative pressure device. The gas can be used for graded treatment on materials which are relatively light in the graded cylinder and materials which are relatively heavy in the graded cylinder, so that a purpose of improving the quality uniformity of a finished product is achieved; meanwhile, the discharge mechanism is arranged at the discharge port, so that continuous discharge can be realized, and the discharge port can be sealed during feeding at a negative pressure, and therefore, the airtightness in the negative pressure state is guaranteed.

Description

technical field [0001] The invention relates to the technical field of a classifying and discharging device and material classifying equipment, in particular to a classifying and discharging device of a dry ball mill system. Background technique [0002] The classification device is a circular air classifier. The head of the existing classifier has a main fan to provide the flow power of the classified air, and an integral shaft drives the main fan, centrifugal disc and axial flow fan. The material enters the centrifugal disc from the upper end without air seal, and the centrifugal disc disperses and distributes the feed material radially to the peripheral plate. The airflow is accelerated by the combination of the axial flow fan and the blade ring, and the upward flow of the spiral airflow drives the feed. materials. The fine powder is mixed in the airflow, while the coarse material falls down, and the fine powder mixed in the airflow is transported to the outside of the c...
