[0029] The drum crushing and grinding machine is mainly composed of a supporting structure, a sealing door, an outer screen, an inner screen, a screen frame, a steel rod, an outer cover of the machine body, a penetration component and a motor.

[0030] The supporting structure is located on both sides of the drum crushing and grinding machine to support the rolling of the grinding barrel.

[0031] The sealing door is connected to the outer cover of the machine body with a hinge structure and is manually locked and sealed. A floating seal is provided on the door to seal the window on the door and the inner screen at the same time to prevent the material from flying out during the rotation. A disc is provided on the door, which is driven by a cylinder to push it into the skeleton oil seal after the door is closed.

[0032] The outer screen adopts a single-piece plug-in structure. The outer screen is made of stainless steel thin plate with stainless steel screen inserted inside. When in use, it can be directly inserted into the slot of the screen support frame. The aperture of the outer screen can be selected in the range of 150 mesh to 20 mesh. When 150 mesh is selected, the diameter of the screened material is less than 0.1mm.

[0033] The inner screen is made of a stainless steel mesh barrel welded with built-in support rings on both sides. Guide shafts are welded on both sides of the mesh barrel to facilitate installation in the mesh support frame. After the inner screen is installed, the outer baffle squeezes the inner screen into the mesh support frame. A baffle is welded on the outside of the opening on the screen. This opening is used to recover particles that can pass through the inner screen but cannot pass through the outer screen.

[0034] The screen frame is composed of support plates on both sides and 6 tension shafts. It is equipped with two guide grooves inside for installing the inner screen and 4 two-way slots outside for installing the outer screen.

[0035] There are steel bars inside, the size of which is greater than Φ30×350mm. The steel bars are made of stainless iron and each weighs about 2kg.

[0036] The upper cover and the lower hopper of the machine body are made of stainless steel by bending and welding. After processing, they are connected to external equipment with screws. Sealing strips are added at the joints and the interior is polished to prevent the powder after grinding from flying and facilitate recycling below. A vibrator is set at the funnel below the outer cover to knock on the hopper and vibrate to facilitate discharge.

[0037] The penetration component and motor are used to provide power for the equipment, and are composed of a servo motor, a reducer, a magnetic fluid, and a commutator.

[0038] Working principle of double-layer screen grinding machine:

[0039] a) The inner screen is made of a mesh plate with a 1.5mm aperture and a support ring welded inside. The outer screen is made of a stainless steel plate with a 150-mesh screen clamped inside. The screens are available in a variety of specifications.

[0040] b) The grinding rod is crushed and ground on the inner net, and the material falls onto the outer net through the 1.5mm screen. A part of the filterable material with a mesh size less than 150 leaks out of the outer net through the screen holes by its own gravity and falls below.

[0041] c) The grinding machine rotates clockwise. After the crushed materials pass through the inner screen, the qualified materials penetrate the outer screen and fall into the outside. The other part of the materials between 1.5mm and the screen specifications rotates with the screen. When it turns to the position shown in the figure above, the materials fall into the material recovery port and enter the inner screen.

[0042] d) Repeat this process until all materials are screened.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
