Are belt cushion beds any good? What are the advantages of a buffer bed?

Belt buffer bed is used to replace the roller, mainly used in raw coal transportation, cement plant, molybdenum ore, iron ore conveying system, because the impact force is larger, the general buffer bed is difficult to withstand such a large impact force, the design can be diversified, mainly according to the customer's belt conveyor and use conditions through professional design.

Luoyang Ruita Rubber Co., Ltd. is the most professional belt buffer bed manufacturer, buffer strips, buffer beds are produced in full accordance with international standards, Ruita engineers according to the customer's specific working conditions, design and production to meet the actual needs of customers to use the buffer bed, Ruita belt buffer bed minimum service life of 1 year, general working conditions more than 2 years, greatly reducing the cost of customer use, Ruita is willing to solve the problem, welcome users to compare the use of the same type of products, Ruita adhere to the quality, believe in your choice!

The belt buffer bed is composed of buffer strips, and the buffer strips are mainly used with excellent high-elasticity special rubber layer, which fully and effectively absorbs the impact force of the material when it falls, greatly reduces the impact of the material on the conveyor belt when it falls, and truly improves the stress condition of the blanking point. And the special UHMW polymer polyethylene surface is used to minimize the friction coefficient between the conveyor belt and the buffer strip, and the wear resistance is good. The use of buffer bed ensures the contact between the surface of the conveyor belt, and the force is uniform, which effectively prevents the longitudinal tearing of the belt caused by the breakage and falling off of the roller, and greatly reduces the probability of longitudinal tearing of the belt after being penetrated by sharp objects or sharp materials.

It is indeed better than the roller, and I recommend Luoyang Ruita Rubber Company to you for the belt buffer bed, which is very professional in China!

Belt buffer bed is a special buffer equipment for mining conveyor belt conveyor, which has the characteristics of impact resistance, smashing resistance, flame retardant, antistatic, anti-corrosion, etc., and is the best tool to replace the buffer roller, which realizes the surface contact between the buffer strip and the conveyor belt, and effectively prevents the damage to the conveyor belt.

Of course, it is better than the roller.

1. The role and advantages of all belt buffer beds.

The buffer bed is used to protect the belt, the buffer strip is to play a shock-absorbing effect, and the design and manufacture of the buffer strip of the belt buffer bed involves the fields of engineering mechanics and machinery manufacturing. The RIT buffer bed mainly plays a triple cushion, namely: the first buffer between the belt conveyor and the buffer strip; The rubber layer in the middle of the buffer strip is the second cushion; The buffer bar and the bottom steel plate are the third buffer.

The belt buffer bed realizes the contact between the belt and the buffer strip, and the force is uniform, which effectively prevents the longitudinal tear of the belt caused by the breakage and falling off of the roller, and greatly reduces the probability of the belt tearing caused by the belt being penetrated by iron or sharp materials. The buffer rubber and anti-rust steel structural parts are three-fold vulcanized, the strip body is beautiful, smooth and uniform, the two ends of the buffer strip body slide in an arc to ensure the smooth passage of the conveyor belt, and the fixing method adopts the "inverted mountain" fixed structure, and the fixing bolt is firmly stuck in the bottom chute, even if the impact is large, it will not be loose.

The ultra-high molecular weight polyethylene surface minimizes the coefficient of friction between the conveyor belt and the buffer bed, and has good wear resistance. It can effectively eliminate the splashing and scattering of materials caused by the uneven force of the conveyor belt into a wavy shape.

I think the buffer bed can replace the buffer roller, it is very suitable for various conveying processes and the operation of materials, is according to the belt bandwidth, belt speed, material characteristics and processing capacity, maximum particle size, falling height and other parameters to provide the design and transformation of the buffer bed.

Comparison table of performance of impact bed and buffer roller:

1.Tear Resistant:

The longitudinal setting of the buffer bed is consistent with the direction of the belt running, which can effectively prevent the belt from tearing, the spacing of the buffer roller group is large, and the axial direction of the roller is perpendicular to the running direction of the belt, and the foreign objects such as steel bars in the material are easy to insert into the belt and get stuck between the rollers, thereby tearing the belt; Secondly, the buffer roller may also jump out of the roller frame groove due to the impact of gravity, resulting in the inability to return to the position and jam the belt.

2.Sealing, anti-spill effect:

The buffer bed supports the belt as a whole, and the belt will not sink when blanking, so it can effectively correct the blanking, prevent the belt from drifting, and prevent overflow; When the buffer roller group is heavily loaded, it will cause the belt to sag, and the sealing effect is not good.

3.Cushioning effect:

The overall cushioning effect of the buffer bed is good, providing comprehensive support for the belt in the blanking area, and the overall cushioning effect is excellent; The buffer idler sets are all in a single form, and the cushioning effect is poor.

The buffer bed is divided into light buffer bed, heavy buffer bed, super heavy buffer bed buffer bed from the use of the buffer bed: general buffer bed, coal mine underground flame retardant buffer bed heavy buffer bed is generally in the cement plant or coal gangue conveyor belt conveyor transportation process, for the material particles are relatively large, the drop is relatively high in the case of use, it can withstand the maximum conveying capacity is less than 3000 tons per hour, in order to enhance the impact resistance, generally use I-beam design, In special cases, 5 support beams should be used, and the overall reinforcement should be made after welding, and the buffer slider should be lined with 10mm steel plate below when fixed, so as to increase its load-bearing capacity, and the weight of a heavy-duty buffer bed with a width of 1200mm may reach about 600kg, which absolutely guarantees the cushioning effect!

It adopts I-beam design, and the conveying material is coal gangue or stone, and the blanking height is higher than 5 meters.

The conventional buffer bed can use 3-4 support beams, using general channel steel design, suitable for raw coal, small coal chips and other surface loose materials, and the blanking height is less than 3 meters.

There is a heavy-duty buffer bed in the cement plant or coal gangue conveyor belt conveyor transportation process can be seen, the particles are relatively large, the drop is relatively high, the maximum conveying capacity it can withstand is less than 2800 tons per hour, enhance the impact resistance, the use of I-beam design, the use of 5 support beams, after welding to the overall reinforcement, the buffer slider in the fixed, below the lining of 10mm steel plate, increase its load-bearing capacity, a width of 1200mm heavy-duty buffer bed weight may reach about 500kg, Guaranteed cushioning effect.

The general buffer bed can use 3-4 support beams, using general channel steel design, suitable for raw coal, small coal dust and other loose materials, blanking height less than 3 meters under the working conditions, commonly found in power plants.

The belt buffer bed realizes the contact between the stool belt and the buffer strip, the force is uniform, and the probability of belt tearing is effectively reduced. The occurrence of phenomena such as opening the royal bar.

The buffer bed of the mine belt conveyor is also called the buffer chute, which is used at the first point of the material, instead of the roller, which can fully absorb the impact of the material falling, dustproof sealing, protection of the conveyor belt and other advantages, reducing the friction when the belt is running, "Ruita" buffer bed is "tailor-made" according to the conditions of the site, "one machine and one design", which effectively ensures the convenience of the buffer bed in the later stage of installation and maintenance, and can be used in the material conveying system such as mine iron ore, steel mill, copper mine, molybdenum ore, quartz stone, fluorite belt conveyor, etc., free of on-site measurement, How fast and easy to install is good and saving, saving costs for enterprises.

Belt conveyor buffer bed is generally used for coal gangue transportation, power plant coal conveying system, port terminal and other large materials, high belt speed material buffer, used instead of roller use, with good sealing effect of the stove, high strength to absorb the impact of the advantage, will not damage the belt, prolong the service life of the conveying and branching belt, according to the appearance is divided into, coal mine (coal preparation plant) flame retardant buffer bed [black], ordinary buffer bed [red], suitable for power plants, cement plants, mining industry, buffer bed instead of roller is already the general trend, Save costs for enterprises and reduce maintenance costs!

The buffer bed of the coal conveying belt is mainly used for the transportation of raw coal and coal gangue, which requires the characteristics of flame retardant and antistatic, generally adopts channel steel design, and the bed support mechanism adopts flame retardant electrostatic paint baking paint, which avoids the material "hard to hit" falling on the conveyor belt, fully absorbs a large amount of kinetic energy, prolongs the life of the conveyor belt, and is the best product to replace the buffer roller!

The buffer bed used in the coal mine is generally divided into: medium-sized, heavy-duty, and super-heavy, the former uses a reinforced digging blue channel steel design, and the heavy-duty and super-heavy ones generally use I-beam design, which is beautiful and generous after processing, which greatly reduces the maintenance cost of the enterprise!

Instead of the traditional buffer roller, the buffer roller is mainly used before the blanking buffer bed is used, which has been used for decades, but the resulting conveyor belt tearing, as well as the tight sealing of the blanking port, and the accumulation of material falling have been plaguing the user, which has also led to a great waste of production capacity and increased the cost of labor. Blanking accumulation Material accumulation and longitudinal tearing of the conveyor belt Disadvantages of traditional idler supports.

1. The cushioning capacity of the supporting roller is poor, and it cannot absorb the strong impact force of the falling material well, and it is easy to smash the supporting roller, resulting in the hidden danger of longitudinal tearing of the belt.

2. The supporting roller is easy to fall off due to the impact of the material, and the upright support seat of the supporting roller is easy to hang up or tear the belt.

3. The supporting roller and the conveyor belt are in line contact, and the two rollers are suspended, which is susceptible to the material ring and other sharp hard objects to penetrate the belt between the two rollers, and get stuck between the roller and the blanking port, resulting in longitudinal tearing of the belt.

4. The belt between the two rollers is easy to sag, so that the belt between the blanking port is wavy, so that the sealing of the blanking port is not good, resulting in material scattering and environmental pollution.

5. The surface of the supporting roller is inelastic, and the surface is easy to adhere to materials during long-term operation, wear the belt, and in serious cases, it will cause the belt to deviate.

6. The rotating bearing of the supporting roller has been impacted for a long time, and the seal of the bearing is easy to fail, resulting in the inflexible rotation of the roller body or non-rotation, and the surface of the belt is worn.

To this end, many international engineering design companies have designed different material buffer devices to improve the material buffer, and finally the buffer bed invented by German engineers has been recognized by customers after gradual improvement and has been adopted by the world. The international general structure of the buffer strip is composed of three parts: ultra-high molecular weight polyethylene plate + elastic rubber + steel pole, this structure is after a long time of design and application adjustment, finally determined, this structure is the international more common structure, due to the relatively backward process technology in the domestic market, so that there are almost no manufacturers who can produce this structure, through the following technical analysis and practical cases we can well understand this problem.
