Description

Symmetrical chrome corundum granular screening device

Technical Field

The utility model relates to a symmetrical chrome corundum granular material screening device, belonging to the technical field of chrome corundum production.

Background Art

Chrome corundum is made of alumina powder after the crushing of alumina blocks as the main raw material, adapted to chromium oxide, etc., and smelted at high temperature. It has higher toughness than white corundum. Alumina is a high-hardness compound. After coarse crushing by a jaw crusher, it needs to be finely crushed by a roller crusher to meet the particle size requirements of the subsequent process. The material after fine crushing by the roller crusher needs to pass through a screening machine to screen out materials of different particle sizes. Those that meet the requirements will enter the next process, and those that do not meet the requirements will return to the previous crushing device for further crushing.

Since the crushing device has a large crushing capacity, the sorting flow of the screening device cannot meet the requirements, which causes the crushing device to stop intermittently, affecting production efficiency.

Utility Model Content

Based on the above shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a symmetrical chrome corundum granular screening device with a large sorting flow rate to solve the above problems.

The symmetrical chrome corundum granular material screening device described in the utility model comprises two symmetrically arranged screening machines, the blanking ends of the two screening machines are butt-jointed together, and a material box is arranged above the blanking ends; the screens at the blanking ends of the two screening machines are covered with a blanking receiving plate, and the blanking receiving plate can move relative to the screening machine.

Two screening machines are configured in one material box to increase the screening flow. The screen is covered with a material receiving plate to prevent the falling material from causing damage to the screen, and the material receiving plate can move relative to the screening machine, that is, the two screening machines are not rigidly connected, which does not affect the vibration screening effect of the screening machine.

Among them, each screening machine is provided with a horizontal support rod at the drop end, and the drop receiving plate is located on the two support rods; the drop receiving plate is equipped with a limit device to prevent it from vibrating and falling.

Furthermore, the limiting device is a limiting bolt, which is installed on the left and right baffles of the screening machine; vertical limiting baffles are provided on both sides of the front and rear ends of the blanking receiving plate.

Furthermore, a gap is left between the limit baffle and the limit bolt, and the blanking receiving plate can move slightly between the front and rear limit bolts.

The material box of the utility model is installed on a supporting frame, and the supporting frame spans over the material dropping ends of two screening machines.

Wherein, the two ends of the material box are provided with supporting ears, and the supporting ears are installed on the supporting frame through fixing bolts.

Compared with the prior art, the utility model has the following beneficial effects:

The symmetrical chrome corundum granular material screening device described in the utility model solves the problem of intermittent shutdown of the crushing device, which affects the production efficiency. Two screening machines are configured for one material box to increase the screening flow rate. The screen is covered with a falling material receiving plate to prevent the falling material from causing impact damage to the screen, and the falling material receiving plate can move relative to the screening machine, that is, the two screening machines are not rigidly connected, which does not affect the vibration screening effect of the screening machine. The device has a simple structure and can effectively improve production efficiency.
