Crusher conveyor belts are very important machinery and equipment in the mining industry, and they also play an important role in various industries. This article mainly introduces the working principle of the crusher conveyor belt, the classification of the crusher conveyor belt and the common crusher conveyor belts, as well as some common problems of the crusher conveyor belt. I hope it can help everyone.
What is a crusher conveyor belt?
A crusher belt is a system that carries a belt conveyor, often referred to as a crusher belt. A crusher belt system consists of a number of belts. A crusher belt system consists of two or more pulleys with a closed loop of belts rotating around them.
One or two pulley drives move the belt and material on it forward. Powered pulleys are called drive pulleys while unpowered pulleys are called idler pulleys. Crusher conveyor belts are mainly used to transport a large amount of resources, such as ore and sand.
How does a crusher conveyor belt work?
The principle of the crusher conveyor belt is that after the object is placed on the conveyor belt, it slides relative to the transmission belt, and is accelerated by the sliding friction until the speed increases to the same as that of the conveyor belt, and it is relatively stationary with the conveyor belt and keeps moving at a constant speed at the speed of the conveyor belt.
The conveyor belt of the crusher is connected into a closed ring, and they are tensioned by a tensioning device. Under the drive of the motor, the friction between the conveyor belt and the driving roller makes the conveyor belt run continuously, so as to transport the material from the loading end to the The purpose of the uninstall side.
Classification of crusher conveyor belts?
Crusher conveyor belts are generally classified according to the presence or absence of traction elements: crusher conveyor belt equipment with traction elements and crusher conveyor belt equipment without traction elements.
There are many kinds of conveyor belt equipment with traction parts, mainly including belt conveyors, slat conveyors, trolley conveyors, escalators, moving walks, bucket conveyors, bucket elevators, suspension conveyors and aerial ropeways.
Conveyor belt equipment without traction parts commonly has a screw conveyor with rollers for rotating motion.
What are the characteristics of the crusher conveyor belt?
A crusher conveyor belt with traction members generally includes: traction members, load-bearing members, driving devices, tensioning devices, redirecting devices and supports. The traction member is used to transmit traction, which can be a conveyor belt, a traction chain or a wire rope; the load-bearing member is used to hold the material, such as a hopper, a bracket or a spreader.
The driving device gives power to the conveyor, which is generally composed of a motor, a reducer and a brake; the tensioning device generally has two types: screw type and heavy hammer type, which can keep the traction member in a certain tension and sag to ensure the normal operation of the conveyor belt; support The parts are used to support the traction or load-bearing members, and rollers and rollers can be used.
Structural features of crusher conveyor belt equipment with traction parts: the conveyed materials are installed in the bearing member connected with the traction parts, or directly mounted on the traction parts, and the traction parts are connected end to end around each roller or sprocket, forming a structure including: The closed loop of the loaded branch that transports the material and the unloaded branch that does not transport the material uses the continuous movement of the traction element to transport the material.
The structure and composition of the crusher conveyor belt equipment without traction parts are different, and the working components used for conveying materials are also different.
Its structural features are: use the rotary motion or reciprocating motion of the working member, or use the flow of the medium in the pipeline to transport the material forward. For example, the working member of the roller conveyor is a series of rollers, and the rollers rotate to transport the material; the working member of the screw conveyor is a screw, and the screw rotates in the trough to push the material along the trough; the working member of the vibrating conveyor For the trough, the trough reciprocates to transport the materials in it.
What are the common crusher conveyor belts?
It has a wide range of applications, except for materials with a particularly large degree of adhesion, general solid materials and finished objects can be transported with it;
The conveying capacity is large, especially the scale plate conveyor, which generally refers to the double-chain wave type plate conveyor with baffles, and its production capacity can be as high as 1000 tons per hour;
The traction chain has high strength and can be used for long-distance transportation;
The arrangement of the conveying line is flexible. Compared with the belt conveyor, the slat conveyor can be conveyed under the condition of larger inclination angle and smaller bending radius, so the arrangement is more flexible;
During the conveying process, various processes such as sorting, drying, cooling or assembly can be carried out;
stable and reliable operation;
Bucket conveyors mainly transport bulk materials, such as coal. The conveyor belt continuously transports the bucket to a point above the open hatch, where it is emptied into the hold.
Bucket conveyors are suitable for the transportation of materials and powders of certain granularity and bulk in the industries of metallurgy, mining, construction, chemical industry, food, and grain. It includes a drive device, a housing, and a traction chain, a hopper, a head wheel and a tail wheel located in the housing.
The two ends of the shell are provided with a feeding section and a discharging section, and the two sides of the hopper are respectively connected with two parallel traction chains through connecting rings. The head wheel is provided with teeth that match the traction chain, and its conveying forms are inline, L, and Z. Its main advantage is that it has the characteristics of small size, low power consumption, flexible delivery form and sealed delivery.
Belt conveying equipment is a material conveyor that continuously conveys materials on a certain line, also known as continuous conveyor. The conveyor can carry out horizontal, inclined and vertical conveying, and can also form a space conveying line, and the conveying line is generally fixed. The conveyor has a large conveying capacity, a long conveying distance, and can complete several technological operations at the same time during the conveying process, so it is widely used.
The belt conveyor is used for material conveying, using stainless steel mesh belt as the carrier, suitable for drying, dehumidification, freezing and heat treatment in various food industries. Stainless steel products have the characteristics of high temperature resistance and easy cleaning. At the same time, the specific size can also be customized according to customer requirements.
Belt conveyors are mainly used in food, metallurgy, electric power, coal, chemical, building materials, docks and grain industries.
The main structural forms of belt conveyors include horizontal straight conveying, lifting and climbing conveying, and turning conveying. The conveyor belt can also be equipped with accessories such as lifting baffles and side baffles, which can meet various process requirements.
The drive mode of the belt conveyor is driven by a geared motor, which is mainly controlled by frequency conversion and stepless speed change.
High inclination conveyor belt
The high-angle conveyor belt, also known as the corrugated sidewall conveyor belt, is a new type of continuous conveyor belt machinery. It is characterized by simple structure, stable and reliable operation, convenient maintenance and low energy consumption. It is suitable for long-distance horizontal transportation or inclined transportation, and can also be used for assembly and inspection of finished objects.
The characteristics of the large inclination conveyor belt:
- Has a large conveying capacity
- High speed
- Can complete multi-variety collinear sorting and confluence sorting operations
- The transmission length can reach more than 100 meters
- The material temperature is generally between minus 20 degrees Celsius and 40 degrees Celsius
Frequently Asked Questions about Crusher Conveyor Belts?
Belt misalignment is one of the most common faults when a crusher belt is running. There are many reasons for the deviation. The main reasons are the low installation accuracy and poor daily maintenance. During the installation process, the head and tail rollers and the middle idler should be on the same center line as much as possible, and they should be parallel to each other to ensure transportation. The belt is not biased or less biased.
In addition, the conveyor belt joint should be correct, and the circumference should be the same on both sides. During use, if deviation occurs, the following inspections should be made to determine the cause and then adjust. The parts and treatment methods that are often checked for conveyor belt deviation are:
Check the misalignment between the lateral centerline of the idler and the longitudinal centerline of the belt conveyor. If the misalignment value exceeds 3 mm, it should be adjusted using the long mounting holes on both sides of the idler set. The specific method is which side of the conveyor belt is biased, which side of the idler group moves forward in the direction of the conveyor belt, or the other side moves backward.
Check the deviation value of the two planes of the head and tail frame mounting bearing seats. If the deviation of the two planes is greater than 1 mm, the two planes should be adjusted in the same plane. The adjustment method of the head drum is: if the conveyor belt deviates to the right side of the drum, the bearing seat on the right side of the drum should move forward or the bearing seat on the left side should move backward.
If the conveyor belt deviates to the left side of the drum, the bearing seat on the left side of the drum should move forward or the right bearing seat should move backward. The adjustment method of the tail drum is just the opposite of that of the head drum.
Check the position of the material on the conveyor belt. The material is not centered on the cross section of the conveyor belt, which will cause the conveyor belt to deviate. If the material is skewed to the right, the belt is skewed to the left and vice versa. In use, the material should be centered as much as possible. In order to reduce or avoid such conveyor belt deviation, a baffle plate can be added to change the direction and position of the material.
In addition to the above-mentioned deviation problems, the conveyor belt of the crusher often suffers from wear, scratches, damages, and cracks at the lap joints. The emergence of these equipment problems not only accelerates the damage of the conveyor belt, but also causes the leakage and waste of materials. Usually, after the equipment problems of the conveyor belt occur, the enterprises use sewing, heating and vulcanization or scrapping and updating. These methods can not solve the equipment problems very well. , the scrapped update has caused the increase of equipment procurement costs.
A safety system for a crusher conveyor belt?
Conveyors used in work environments include decoupling mechanisms, such as decoupling ropes along the length of the conveyor, which allow workers to immediately shut down the conveyor in the event of a problem, including a warning alarm to notify employees that the conveyor belt is about to open. Some other systems used to protect conveyors include belt swing switches, speed switches, belt tear switches, and emergency stops.
If the belt starts to lose alignment along the structure, the belt swing switch will stop the conveyor. If the switch does not register that the belt is running at the desired speed, the speed switch will stop the belt. A belt tear switch will stop the belt in the event of a cut or flip, indicating the risk of further damage to the belt, an emergency stop may be located on the conveyor control box to prevent tripping failures.
The future development direction of crusher conveyor belt?
In the future, the crusher conveyor belt equipment will develop towards large-scale development, expanding the scope of use, automatic sorting of materials, reducing energy consumption and reducing pollution.
Large-scale includes large conveying capacity, large single machine length and large conveying inclination. And now there have been several belt conveyors that connect the two places, and many countries are now exploring a more complete conveyor structure for long-distance, large-capacity continuous transportation of materials.
Expanding the scope of use of conveyors refers to the development of products that can work in environments with corrosive, radioactive, and flammable substances under high temperature and low temperature conditions, and can transport hot, explosive, easy to agglomerate, and sticky materials. machine conveyor belt equipment.
