How to choose mine vibrating screen
Vibrating screen manufacturer explains how to select the type of vibrating screen for mine:
First, consider the structure of mining vibrating screen
In terms of structure, the vibrating screen is generally light and heavy. Light vibrating screen is a more common equipment in our life, it is small in size, mainly dealing with food, chemical raw materials, coatings, and so on, usually per hour processing capacity are below 10 tons; And heavy vibrating screen is usually a large processing capacity, the processing capacity of hundreds of tons per hour or more, can deal with such as coal, stone, metal ore and other heavy materials. That is to say, in the mineral processing industry we use heavy vibrating screen, not only because of its mechanical weight is larger, but also more durable, and the processing of the material pile density is also higher. Heavy vibrating screen generally adopts ring groove rivet cold riveted joint frame structure, large clearance bearing olein-lubricated vibrator, screen mostly made of stainless steel, especially the sieve prepared by metal wire, not only good elasticity, but also more wear-resistant corrosion resistance, longer service life in the treatment of iron ore, manganese ore and other materials.
Two, consider the performance of mining vibrating screen
From the performance of the vibrating screen is screening efficiency, due to the proportion of ore material is larger, belongs to the difficult screening material, at the same time because the mineral processing production line is generally operating in the open air environment, so the vibrating screen equipment has the function of dry and wet, so the running track of the material on the screen surface has become the key point affecting the efficiency of the vibrating screen. Through practical research and comparison, circular track vibrating screen vibration is more intense, the material on the screen surface constantly flip, loose, jumping forward running, small particles of material through the screen rate is higher, the material stuck in the screen can also jump out, prevent plugging of the screen; Linear vibrating screen its material on the screen along the straight line jumping reciprocating motion, the material in the forward operation has the role of compaction, so the circular vibrating screen is mainly for large particle material screening, screening, and linear vibrating screen is for finer material screening, selection should pay attention to the difference.
Three, consider the type of mining vibrating screen
Good vibrating screen structure and type of vibrating screen, we also need to segregate the specific type of vibrating screen according to the situation of the dressing production line.
1, screen size, screen shape, etc. It is based on the size and shape of the screening material and the purpose of the vibrating screen equipment, that is to say, it is suitable for pre-screening, inspection or classification screening link in the dressing production line.
2, the number of screen layers. That is to say, we need to produce several materials, such as two layers of vibrating screen can produce three kinds of materials, a layer for sifting out stone powder, a layer for sending to the grinding machine, a layer can be returned to the crushing equipment.
3. Production capacity. The production capacity of beneficiation vibrating screen should be matched with the whole production line. In the production line vibrating screen is only a link in the production line, so the production capacity of mine vibrating screen should not be less than the design capacity of the whole system, if the selection of mine vibrating screen is too small will limit the play of the system capacity, but should not be too large, will increase the cost and operating costs of all aspects of the input.

Others: carbon black, carbon, cosolvent, activated carbon, wood powder pearl, etc.
Liquid special screen: paint, paint, and viscous liquid.
Technical parameters of linear vibrating screen
Guidance on use and maintenance of linear vibrating screen
1. The machine shall be equipped with electrical protection device.
2. At the initial operation stage of the machine, the anchor bolts shall be checked at least once a day to prevent looseness.
3. When the motor rotation direction does not meet the requirements, adjust the power supply phase sequence.
4. The motor shall be well lubricated, and lithium base grease (ZL-3) shall be added once every two weeks of operation. When refueling, an appropriate amount of lithium base grease shall be added through the oil cup. When sealed bearings are used, the motor is not equipped with oil cups.
5. After the machine has been running for 1500 hours, check the bearing and replace it immediately in case of serious damage.
6. When the machine is used again after being stopped for a long time, the insulation resistance should be measured, which should be greater than 0.5 megohm for 500 volt megger measurement.
Daily maintenance of linear vibrating screen
1. Before starting:
(1) Check whether the coarse mesh and fine mesh are damaged;
(2) Check whether the transportation support is removed.
2. At startup:
(1) Pay attention to whether there is abnormal noise;
(2) Whether the current is stable;
(3) Whether the vibration is abnormal.
3. After use: clean up after each use.
Regular maintenance of linear vibrating screen
Regularly check the coarse screen, fine screen and spring for fatigue and damage, and check whether all parts of the machine body are damaged due to vibration. The parts that need to be lubricated must be lubricated.
About Transportation
After you place the order and pay the deposit, we will start to arrange the production and contact the ocean freight transportation agency to reserve the position. Two days before the end of production, you need to complete the final payment. Then, we inform the ocean cargo transportation agent company that it is ready to come to the factory to pull the goods to the port. On the day of delivery, we will send the customer the factory video and pictures, and mark the corresponding English name of each product and product parts with a marker to prevent the customer from not knowing what each part is after receiving the goods. At the same time, we will put the English version of the product instructions in the cargo box. We generally select freight forwarders with preferential prices for customers to deliver goods for you. The shipping method can be FOB or CIF. You can also choose EXW, and then contact the goods agent company yourself.
