As the rapid development of concrete technology, making high-performance sand making machine using mechanism sand made by sand maker or sand making machine is also increasing, and main high-performance sand making machines are mechanism sand anti-disturbance concrete, mechanism sand pipe dense concrete, mechanism sand water anti-dispersed concrete, mechanism sand dense tablets stone concrete, mechanism sand super high pump big volume concrete, mechanism sand high-strength high-performance concrete, metamorphic rock alkali aggregate reaction inhibition concrete, etc. These sand making machines have been widely used in major projects in China, and have achieved remarkable economic, as well as social and environmental benefits.
Disturbance-resistant concrete is new type of concrete which adapts to modern transportation technology and development requirements, and it can withstand traffic loads caused by the vehicle-bridge coupling vibration on hardened concrete damage injury, and thus guarantee the pavement and casting to be carried out without interrupting the bridge traffic.
With the increasing investment boom of artificial sand, the gold period for sand making plant is coming. Along with vigorous advance of Twelfth Five-Year plan, the infrastructure construction has got rapid develop.
1. When the material is in the machine, we cannot start the sand making machinery. If we do this, the power driver will be damaged. So we should start the machine firstly and then feed the ore material into the sand making machinery.
2. Each crusher has its application scope, sand making machinery is the same. The ore material that enters into the machine has a specific particle size. If the material is too large, it will block the feeding port of the sand making machinery. If this phenomenon happens, we should sweep the machine and it also will affect the production process. When the impeller is damaged, we should change it to ensure the normal operation of the machine.
3. The sand making plant needs daily maintenance, or the inner parts will be damaged easily because of the attrition. After a period of time, the sand making machinery should be added the lubricating oil to ensure the long working time of the machine.
4. The sand making machinery is fixed by the crews, after the strenuous exercise, the crews will be loose. When the abnormal ring is heard during the operation of sand making machinery, we should stop the machine and check it timely.
In Henan province, there are many customers use the new type of sand making machinery. This province has good stone resources; so many customers invest the production of DY series sand making machinery. Hammer crusher is popular in the last years, but nowadays, the sand making machinery has a good develop prospect in the future.
Characteristics of high-performance sand making machines:
High-traffic disturbance, can resist or weaken various perturbation caused by mechanical or artificial destruction.
Reasonable mistiming between initial setting and final setting, traffic disturbances have the greatest level of influence on concrete performance in the condensed phase, particularly in early coagulation stage.
High strength, resistance to disturbance of concrete strength, can greatly reduce the negative effects of traffic disturbances, and meet the needs of remedial works caused by constantly interrupted traffic;
High crack resistance, disturbance-resistant concrete is not bleeding. It has a very high resistance to cracking, especially early shrinkage cracking resistance can greatly resist gravity damage.
After we have known the working mechanism of the sand making machine, we can focus on the optimization of the workflow. The engineers of Henan Hongxing Mining Machinery believe that the following five aspects should be noted.
First, check if the observation door of the eddy chamber is closed to prevented the material from bursting out of the eddy chamber.
Second, check the rotating direction of the impeller from the direction of the feed inlet. The impeller should rotate counterclockwise, otherwise you should adjust the wiring of the motor.
Third, the startup sequence of the sand making machine and conveying equipment should be as followings: discharging sand making machine feeding. The crusher must be started without load. Feed after the crusher is in normal operation. The stop sequence is contrary to the boot sequence.
Forth, the feed particles strictly follow the regulations. The materials which is greater than the specification should be forbidden into the crusher, otherwise, it would cause imbalance of the impeller or too much wear and tear of the impeller. The impeller channel and the central feed tube even may be blocked ,which will make the crusher not work properly. Immediately remove the large feeding material when you find it.
Fifth, if the discharge device stops moving, it is timely to stop feeding. Otherwise, the impeller will be crushed and the motor will be burned up. In order to ensure the normal operation of the sand maker and give full play to the capacity of the equipment, the majority of sand making machine users should ideologically emphasis on the correct operation of the sand making machine with regular maintenance and periodic maintenance. Properly using the sand maker is an important factor to ensure the continuous normal work of the sand making equipment. Improper operation or negligence in the operation will often cause the accident of the equipment and personal accident. Therefore, correct operation should be strictly in accordance with the provisions of the operating procedures.
VSI sand making machine is a new type of sand making equipment in sand industry, with exploitation of domestic mines, the production out of the sand and gravel aggregate requirements have gradually improved, the old machine can not meet the needs of the market gradually.
Sand making machine is widely used for crushing of hard and crispy materials, such as rocks, grinding materials, refractory materials, cement clinkers, quartzite, iron ores and concrete aggregates. The sand making machine is especially suitable for the sand and sandstone making for construction and road paving. VSI series of high vertical shaft impact crusher is Oriental experts working conditions combined with Chinas latest design achievements, is the exclusive domestic production of high performance sand making equipment with world advanced level.
VSI Impact Sand maker is called as VSI Sand Maker for short, also called as The Third Generation Sand Maker or New-type Sand Maker. Oriental introduced German technology, developed and manufactured this international level high performance new-type sand making equipment; it places an irreplaceable role in fine crushing. Sand making machine is familiar for who is familiar with mining machinery. It is a kind of important sand making equipment. Especially in sand making plant, it decided the efficiency of whole plant.
At present, there are many kinds of sand making machines in market. These sand making machines are different in design and machining which decide the efficiency of machines. VSI sand maker made by Shanghai Oriental is the most advanced, and it shows its quality on the details. Sand making machine can cycle many times with the close circuit and the sieve device will control the granularity of finished products. VSI sand maker is an indispensable machine of the sand making production line and is a practical and reliable sand making machine.
