Function of Comb Roller

 Comb roller is also named comb sweep roller,it not only has a good leakproofness，but also has many omnibus characteristic，such as wear resistance,fatigue durability,corrosion resistance,ageing resistance,tear resistance,buffer performance,good elasticity,etc.It is usually installed on the return segment,the structure of comb roller is more complex than ordinary roller,as shown in the following drawings,there are some quantity of rubber rings on the roller surface,to avoid the direct contact between roller and belt,so it makes a good protection for rollers,in addition,the maintenance cost of comb roller is much lower,once roller wears,only need to change the rubber rings.
The comb roller also can protect the belt,during conveying,some material will spatter on the return belt inner surface,if don’t clear them in time, they will wear the roller and belt,even cause the belt deviation,however,comb will solve this trouble,because there are intervals between rubber rings,the material which spattered will fall into the intervals,they will not wear the belt,and because of the comb roller structure,the material will be cleaned up.

Ultrasonic Vibrating Screen Used for Battery Powder Industry Separation

Battery powder is a battery containing magnetic metals such as lead, nickel, lithium and magnet properties of non-metallic materials. During the treatment of the entire process , vibrating screen plays an important role, we often choose ultrasonic vibrating screen because the separation material belongs to powder material.
Compared with ordinary rotary vibrating screen , ultrasonic vibrating screen is equipped with an extra ultrasonic system, which allow the ultra fine powder can accept the huge acceleration of ultrasound, it can solve adhesion, friction and blockage in the screening of ultra fine powder when using the common rotary vibrating screen and improve the screening efficiency and net cleaning efficiency.
Security is very important in screening because these materials are presented with a certain degree of magnetism and electrical conductivity, these items belong to the secondary water lighted objects,besides as material is slender and easy to float in the air, under the influence of moisture in the air,it will produce hydrogen, which is flammable once it is in the fire,the instantaneous explosion will occur,thus the ultrasonic vibrating system requires a explosion-proof motor.

FEEDING MATERIAL IN PROPER ORDER OF BURIED SCRAPER CONVEYOR

Equipment failure happens when improper operation made in the running process of buried chain scraper conveyor. Please pay attention to the the material feeding sequence.

During material conveying, turning on the device at the first place and opening feed inlet afterwards. In this case, scraper conveyor would not be filled with material avoiding unnecessary losses because of overload motor. When material conveying finished, turn off the slide damperor or the power of the discharger firstly, stop material feeding and turnoff squeegee machine after clean up the material in the conveyor chamber. It will prevent the material accumulation in the equipment avoiding material moisture and agglomeration.

Bucket Elevator with Explosion Safety Protection Device

Frankly speaking, it’s really necessary to install safety protection device on bucket elevator so as to ensure normal operation. Now, what is the significant inspection standard for equipment quality is that to minimize or completely eliminate all kinds of risks. According to structure of bucket elevator, there are many kinds of safety protection device. We can divide into the following protection devices based on their function: explosion safety protection device, running deviation safety protection device, overload, speed measurement and reversion protection device.
Here we will mainly introduce the explosion safety protection device. Because working components of bucket elevator and material running speed are relatively fast, also they are running in the sealing casing, if there are many dusts in materials, it will cause high dust contained. In the grain industry, materials always contain many flammable organic dusts, once dust content is too high, it maybe blast when meeting open-flame. Therefore, both design and application of bucket elevator must consider the explosion precaution.
Main measure: Please leave a dust mouth above the bucket elevator head drive. When conveying materials which will cause dust explosion, at this time please open the dust mouth, install dust collector and reduce dust concentration to make it have no necessary explosion conditions.

Type and Feature of Belt Conveyor Tension Device

Tension Device is one of the core compositions in the belt conveyor, mainly used to supply certain tension force for the normal operation of the conveyor belt. Therefore, selecting proper tension device is the key to design belt conveyor. There are three types of tension device, in the following the feature of these three device would be introduced.

1. Screw-type tension device

The screw type tension device is installed at the tailing pulley of the belt conveyor and adjust the tension of the conveyor belt through regulating the screw to make it move.

It is generally applied in the belt conveyor with belt length less than 60 meters and small power. The series of belt conveyor tension device including 500mm and 800mm there stow kind.

2. Vehicle-type tension device

The vehicle-type tension device means installing the tail pulley on the movable vehicle, and use the steel rope to connect the vehicle and heavy hammer separately through the revising pulley, this automatically tension the conveyor belt by the gravity of the heavy hammer.

3. Vertical hammer type tension device

The vertical hammer type tension device is installed between the transmission pulley and the tailing pulley, and should be close to the site with least tension. It reacts quickly when the belt conveyor starts working with good tension effect.

How to Check Short Circuit in Winding of the Bucket Elevator

The bucket elevator has the advantage of large conveying capacity, high lifting height and long service time. Many of us would wondering why short circuit in winding happens in the operation, this passage introduces the methods for checking the short circuit in winding in the following:

1. Check the electrical bridge;

Measure the direct-current resistance of winding. The general phase difference should not exceed 5%, if it exceeds, we can confirm that the phase with small electrical resistance has short trouble.

2. Power the elevator and do experiment;

Measure the current by ammeter, short trouble exists where there is high current.

3. Observe the surface of the bucket elevator;

Observe whether there is burn at the connecting box and the winding overhang.

4. Check the temperature of the bucket elevator;

Operate the elevator without load for 20 minutes(power it off immediately if there is any abnormal phenomenon), and touch each part of the winding part to see if the temperature is higher than the normal temperature.

5. Check by the millimeter or the Meg-ohmmeter;

Measure the insulation resistance between two any phase, if it is very low or shows no resistance, then it means there is short trouble here.

The Use Skill of Corrugated Sidewall Belt Conveyor

Corrugated sidewall belt conveyor is widely used in material handling industry. It has a lot of advantage, higher transportation capacity, the material is not easy to leak, slide prevention etc, it is welcomed by the masses of customers. So what are the use skill of corrugated sidewall belt conveyor in the process of using ?Here, Henan Pingyuan Mining Machinery Co., Ltd answers for you.
1.It is strictly prohibited to use different belt together.
2.The transport direction of the material and the dropping speed of material should be consistent with belt conveyor.
3.Non-load machine start, in order to avoid motor overload and large angle conveyor belt skid, before shutdown, all material should be unloaded completely.
4.When using corrugated sidewall belt, you should prevent belt folding and hard objects pressing, it should be curly using and preservation.
5.Corrugated sidewall belt tension should not be too big, please guarantee that it is used under the minimum tension.
6.In the using of corrugated sidewall belt, if there is a sliding or pulling up phenomenon, you should timely troubleshooting, adjust the tension system, keep the elastic device is flexible.
7.If there is belt deviation or sinusoidal running , you should adjust it timely.
