Explore the characteristics of multi-wire sawing machines in Italy

diamond wire sawing is an important equipment for processing granite slabs for a long time. However, because of its low production efficiency, difficulty in operation, and environmental pollution, many companies now prefer to use a large-scale sand saw instead of a circular saw. produce. Due to the development of synthetic diamonds, the use of circular saws has a lower production cost, coupled with less initial investment. Therefore, the current equipment for sawing granite in China is mainly circular saws. However, disc saw production has the disadvantages of large waste of resources, small plates, and small-scale production that are not conducive to environmental governance; in addition to the increasing labor costs in China, the production technology of circular saws is also growing. Pressure on production costs.
The sawing machine on the granite slab production line calls for the birth of a new type of equipment. The introduction of the granite slab multi-wire saw is to solve the current difficulties encountered in the production of granite slabs. It should be said that it is a kind of Cross-age progress. The era of granite slab production and application of multi-wire saws has arrived.
First, the performance of multi-wire saw
In order to provide readers with a better understanding of this advanced equipment, the benefits of Granite Slab and Multirope Merger from Bederione of Italy are described below:
1. Granite slab multi-rope wire sawing machine CS200 (6 ropes, 16 ropes, 32 ropes, 40 ropes, 56 ropes, 64 ropes, 6 models), can cut 2, 3, 4, 5, 6 at the same time , 7, 8, 9, 250px granite slabs of different thickness. The minimum thickness can cut granite slabs of 25px thickness.
2. The production efficiency of multi-wire saws has been greatly improved. General granite production, the cutting speed is only 30 ~ 40 / h, a 2m high, 3m long block can be cut 8h finished. If you can cut three cycles per day, you can cut 3 standard blocks.
3. The granite slab produced by the multi-wire saw has better quality and flatness. Because each rope can reach 25Okg of tension, the “sand grinding” method of traditional saws is replaced by a real sawing method.
4. The multi-wire saw has a small footprint and saves the cost of land. What's more important is to save a lot of the basic cost necessary for the installation of traditional sand saws.
5. Multi-wire saw is easy to operate. The operation of the sand saw is greatly influenced by the experience of the operator. It is necessary to grasp the concentration of steel sand and lime water, and it is difficult to grasp the operation and even affect the product quality and production cost. Any trained operator of a granite slab multi-rope saw can achieve the same product quality and production costs. More stone information, please pay attention to 365 China Stone Network
6. The system of multi-string sawing water at the toilet is relatively simple and does not require the complex environment-friendly treatment system for the treatment of steel sand and lime water by traditional sand saws. It is more environmentally friendly, but there is only a simple liquid separation system.
Italy's Bederini began developing granite granite slabs and multi-wire saws to produce granite slabs from 200 years ago. It has been practiced for more than three years. So far, 29 units have been sold all over the world, and all of them have been operating in a stable position. Among them, a Brazilian company owns 2 sets of 64 ropes, 1 set of 40 rope granite slabs and multi-rope silver, which can produce 2500 square meters per day. Granite slabs.
Second, Italy's Beddolin company GS200 granite slab multi-wire saw technical characteristics
Since the Italian company Bedrini is not a manufacturer of diamond ropes, diamond rope cost data comes from the actual data of multi-wire saws used in Italy, Brazil, Saudi Arabia, India and Poland. Diamond ropes are usually sold at a price per metre, and the price varies depending on the diamond rope supplier's agreement and import duties. It should be pointed out that the maximum speed of diamond rope production refers to the maximum downward cutting speed in use, and the actual production speed refers to the corresponding downward cutting speed when the fully automatic circulation type is applied.
1. Characteristics of diamond rope
The type of material that can be cut: Mixed gangue: Number of beads: 36/m; sawing speed 0.8~1.2m2/m Lifetime 8~12m2/m; Diameter 7.3mm. With this new rope customer can reduce sawing costs and improve production efficiency. In order to avoid prolonged cutting and save reassembly time, the 7.3 rope is for single use.
2. Operational Precautions
Before sawing, the blocks are best shaped at the top and bottom: Blocks should be placed on two supports and cemented; the standard ropes of the multi-wire saws are injection-molded with transparent plastic and they consist of 36 beads of 1m. Usually do not need to be edged.
Third, the production capacity of granite slab multi-rope wire saw
Taking CS200-64 granite slab multi-wire saw as an example, if the blockage pressure is 3m in length and 2m in height, the calculation is as follows:
If Grade 3 granite, the cutting speed is 0.85m2, if the length of the block is 3m, the downsaw speed is 707.5px/h. If the height of the block is 1.8m, 1.8*100/707.5px/h=6.36h. The time to replace the block is 30 minutes. Cutting length 3m. Height 11.8m blocks, production cycle is about 7~8h
. If you produce 2 cycles per day. Can produce 52.5px thick plate 680.4m2.
Fourth, the patented technology of the multi-wire saw of the bedriini company
1. Multi-rope According to the diameter of 2.3m, the large flywheel is covered with a number of invariable anti-wear materials. Instead of vulcanizing and sticking with large flywheels. . This lining is easy to change and maintain.
2. Multi-rope According to the left is a patented technology of multi-wire saw
1. Multi-rope According to the large-scale flywheel with a diameter of 2.3m, it is ensured that the diamond rope is driven through a very long arc contact, reducing the bending stress of the rope. On the right side, the rope is in contact with the robber, so that the service life of the diamond rope can be extended to 400 to 500 hours. This enables the diamond beads to be completely worn.
3. Adopt the secondary hydraulic tensioning system on the moon and tighten the right whole wheel assembly (the entire tensioning wheel set can move 150mm stroke). Separate tensioning with each rope (each rope wheel can move 110mm stroke) to maintain the same degree of tension in the cutting process.
4. The use of a number of independent rubber roller guide wheels, easy to replace and maintain, rubber roller rubber liner life longer. Since each rubber roller has its own bearing, the speed of rotation of each set of rollers is free to rotate relative to the other rollers, thereby maintaining the same speed of the diamond rope that each roller contacts.
5. Use a 4-position rope cleaning system. Reduce the dirt of the machine, reduce the wear of the rope drive wheel and idler cover tape, extend the life of the diamond rope and improve the performance of the diamond rope.
6. In the sawing process, the spacers between the large plates can be automatically placed without downtime, thereby saving downtime.
