The trommel screen is reliable in operation and small in maintenance. The following briefly describes the points that should be paid attention to during operation:
1.Turn on the trommel screen first, then turn on the feeding equipment; when stopping, turn off the feeding equipment first, and then turn off the trommel screen;
2.Three days before operation, check the trommel screen fasteners every day, and tighten them in time if they are loose. In the future, the drum screen fasteners can be inspected and processed regularly (weekly or half a month);
3.The lubrication of the bearing seat and gearbox should be checked regularly, and the oil should be added and changed in time. The large shaft bearing adopts No. 2 lithium-based grease. Under normal circumstances, the grease should be refilled once every two months, and the filling amount should not be too much, otherwise the bearing will be easily overheated. All bearings should be cleaned and inspected once a year.
4.When the equipment is out of service for a long time (more than 30 days) and restarted, the motor insulation should be telemetry to prevent the motor from burning.

First, the trommel. The trommel screen is very suitable for screening sand and gravel, and it can be configured as a complete set. It can be used in various industries with belt conveyors and hoppers. In use, it has slow and uniform operation, low impact, stable work and simple installation. Features.

Second, the linear vibrating screen. When sieving sand and gravel with a linear screen, it can be finer, and the output is usually not as large as a drum screen.

Third, circular vibrating screen: It is a large-scale vibrating screen that can sieve materials into a variety of grades according to their particle size, and has a wide range of uses. It has the advantages of multiple screening specifications, strong excitation force, simple structure, large processing capacity, high screening efficiency and long service life.

Fourth, high-frequency vibrating screen: It is a kind of sand and gravel screening equipment with high frequency, which has good screening effect and large processing capacity, and can be used in many occasions.

First of all, bucket elevators can generally be driven by belts or chains. In order to reduce damage to the materials, belt transmission is used as much as possible in the grain elevator, and chain transmission is used less to reduce the material and equipment during the lifting process. Friction contact to avoid damage.

Secondly, in order to solve this problem, the grain elevator can adopt a closed-end deep bucket, which can reduce the overflow of the grain from the hopper and reduce the damage of the seed.

Third, the grain elevator can use a plastic bucket to reduce the hardness of the hopper, so that the impact force is not so great when it comes into contact with the material, and the wear of the material is reduced.

1. The production load is too large, causing the equipment to run overloaded and cannot bear it, and the screen box cracks and the beam breaks failure;
2. The parts in the screen box such as the screen mesh are loose due to various reasons and resonate with the vibrating screen, causing cracking failure;
3. Due to the design of the equipment itself, the steel beam of the screen box is relatively thin and cannot adapt to the harsh production environment, causing the equipment to crack;
4. Cracking caused by the vibration of the vibrating screen.

1.Pay attention to the shape of the material, confirm whether the material is small, granular or powdery, and what are the physical properties of the material being transported, that is, whether it contains water, viscosity or adsorption.
2.The specific gravity of the material. Generally speaking, the ordinary bucket elevator is only for the case where the pile-to-weight ratio is 1.6. If the selection process of the bucket elevator is specifically clarified, it is from the specific gravity of the material to the transmission mode to the nature of the material and the discharging method.
3.Then there is the shape of hoppers, mainly shallow buckets, deep buckets, etc., but also different materials, plastic buckets, carbon steel buckets and stainless steel buckets, etc.

1. The vibration motor is installed on both sides of the linear vibrating screen.
This type of installation is also a common method for vibrating motors in linear vibrating screen equipment. Generally, customers have restrictions on the overall height of the device, but there is no restriction on the width of the device.
2. The vibration motor is installed at the bottom of the linear vibrating screen
This is the more common method of installing a vibrating screen vibrating motor. It is generally recommended that customers choose a reliable installation method to save space.
3. The vibration motor is installed on the top of the linear vibrating screen
If the customer is limited in the height and width of the outlet of the linear vibrating screen equipment, no matter whether it is installed at the bottom or on both sides, the vibrating motor cannot meet the requirements. At this time, the vibration motor can be installed in the middle of the top of the device, so that it neither increases the width of the device nor affects the height of the discharge port of the device.
The installation methods of the above-mentioned three vibration motors are the common installation methods of linear vibrating screens. The user can choose the type according to the actual situation.
