A vibrating screen is a mechanical device used to separate materials based on size and shape. It works by using vibration to move materials across a screen or mesh, allowing finer particles to pass through while larger particles are retained. Common applications include mining, construction, and recycling industries.

Vibrating Screen Application

Mining and Quarrying: Separating minerals and aggregates from ores and crushed materials.

Construction: Sifting materials for concrete production, sand and gravel separation.

Food Processing: Screening grains, seeds, and other food products for size and quality control.

Chemical Industry: Separating chemicals, powders, and granules for quality assurance.

Welding rotators are used in various industries to facilitate the welding of cylindrical or round objects, such as pipes, tanks, and other similar structures. They provide support and rotate the workpiece, allowing the welder to work on a stationary weld head, ensuring uniform and consistent welds.

Welding Rotator Operating Instructions

1. Safety Precautions

Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety glasses, welding helmet, gloves, and protective clothing.

Work Area: Ensure the work area is clean, well-lit, and free from flammable materials.

Training: Only trained and authorized personnel should operate the welding rotator.

Inspection: Regularly inspect the rotator for any signs of wear or damage before use.

2. Pre-Operation Checks

Machine Condition: Inspect the welding rotator for any visible damage or wear. Check for loose bolts or connections.

Electrical Connections: Ensure all electrical connections are secure and the power supply matches the machine’s specifications.

Control Panel: Verify that all controls are functioning correctly and emergency stop buttons are operational.

Rollers and Bed: Check that the rollers are free from debris and are properly aligned. Ensure the bed is clean and free from obstructions.

3. Setup

Positioning the Workpiece:

Place the workpiece centrally on the rollers.

Adjust the distance between the rollers to fit the diameter of the workpiece.

Ensure the workpiece is balanced and stable on the rotator.

Aligning the Rotator: Align the rotator with the welding equipment to ensure smooth and consistent welding.

Securing the Workpiece: Depending on the weight and shape of the workpiece, secure it with straps or clamps if necessary.

4. Operating the Welding Rotator

Power On: Turn on the power supply to the welding rotator.

Speed Adjustment: Adjust the rotation speed according to the welding requirements using the control panel.

Start Rotation: Begin rotating the workpiece at a low speed to check for balance and alignment. Gradually increase the speed as needed.

A storage tank welding production line is a specialized setup designed for the efficient manufacturing of storage tanks used in various industries, such as oil and gas, chemicals, water treatment, and food processing.

Key Components of Storage Tank Welding Production Line

Raw Material Preparation:

Sheets of steel or other materials are cut to size and prepared for welding.

Welding Stations:

Automated or semi-automated welding machines perform various types of welding (e.g., TIG, MIG, or submerged arc) to join tank components.

Assembly Line:

Components are assembled in a sequential manner to streamline production.

Inspection Stations:

Quality control measures, including visual inspection and non-destructive testing, ensure weld integrity and overall quality.

Finishing Area:

Tanks are finished through processes such as grinding, painting, or coating to enhance durability and corrosion resistance.

Storage and Logistics:

Finished tanks are stored or transported for installation or further processing.

Storage Tank Welding Production Line Production Process

Design and Planning:

Detailed plans are developed, often using CAD software, to specify dimensions and material requirements.

The roller skin of the briquetting machine is an important part of the briquetting machine. It is located outside the roller core of the briquetting machine. It is usually a cylindrical component with a ball socket on its surface. The shape and size of these ball sockets are designed according to the pressed material and the required product shape. The adjustment of the roller skin of the briquetting machine is a key step to ensure the normal operation of the briquetting machine and improve the product quality.

Briquetting Machine Roller Adjustment

1. Adjustment method

Gap adjustment:

The gap of the roller skin determines the filling amount and molding pressure of the material. The appropriate gap can ensure that the material is evenly distributed between the roller skins and avoid molding problems caused by uneven pressure.

The gap between the roller skins is usually adjusted by adjusting the adjusting nut of the machine. The gap size needs to be adjusted according to the nature of the material and the molding requirements.

In general, the smaller the gap, the denser the molded balls, but too small a gap may cause the equipment to jam or block the material; too large a gap will cause the molding accuracy to decrease.

Parallelism verification:

Use tools and measuring equipment to check the parallelism of the roller skins and make fine adjustments until the two roller skins are completely parallel over the entire length. The guarantee of parallelism helps the material to be evenly stressed between the roller skins and improve the molding quality.

Pressure adjustment:

The pressure of the briquetting machine is usually achieved by adjusting the hydraulic cylinder or mechanical transmission system. The size of the pressure should be adjusted according to the nature of the material and the molding effect. Too low pressure will result in poor spherical quality, while too high pressure may increase the equipment load and energy consumption, and even damage the machine.

High-pressure grinding rolls is mainly used in the ore industry and is also a type of crusher. As the main equipment for crushing in the ore industry, since it is the main equipment, it will be used very frequently. All machines are inseparable from daily maintenance and overhaul. Correct maintenance and overhaul can increase the service life of the machine, and early overhaul can detect problems early, so that small problems will not become bigger, affecting normal work and causing accidents.

Common fault inspection and repair of high-pressure grinding rolls

1. If the lubrication system finds that there is no grease overflow from the labyrinth seal of the bearing seat, the following reasons may be the case:

① lack of oil;

② pipeline failure;

③ grease pump is broken. If the color and properties of the oil flowing out of the oil drain port of the non-loaded bearing seat are found to have changed, it may be that cooling water or other foreign matter has been mixed into the lubricating grease.

2. The movable roller moves irregularly in the horizontal direction. Generally, the nitrogen accumulator pressure is insufficient or damaged.

3. The hydraulic oil temperature is high. It may be: serious internal leakage in the system or the pump has been running for too long, and the hydraulic system needs to be checked.

4. The roller gap is too large. There may be the following reasons:

① Severe wear on the roller surface;

② No pressure;

③ There is material accumulation between the rollers. It needs to be handled as appropriate.

5. The roller gap is too small. It may be that there is a problem with the size of the gap block, or the position of the displacement sensor is set incorrectly.

6. The roller is stuck. It may be that there is foreign matter between the rollers, or there is too much material stored between the rollers when starting.

7. The roller does not rotate. The reasons include:

① Motor failure;

② Reducer failure.

8. The roller surface temperature is too high. It may be that the feed temperature is too high. Measures should be taken to control the upstream raw material temperature, otherwise it will affect the wear resistance of the roller surface and accelerate wear.

9. The bearing temperature is too high. The reasons include:
