River pebbles are named after their pebble-like shape. They have a variety of colors, are hard and wear-resistant, and have beautiful appearances. Therefore, they are deeply loved by builders and are widely used in many fields such as houses, roads, bonsai, and garden construction. And because walking on river pebble roads is conducive to improving human health, river pebbles are also well-known in the field of health.
In recent years, in addition to the above functions, the ability of river pebbles to be used for processing fine machine-made sand has been discovered, and the status of river pebbles in the construction field has been further improved. The fine machine-made sand processed with river pebbles as raw materials has also received affirmation and recognition from manufacturers with high standards!
01. Why is river pebble sand so popular?
In addition to river pebbles, granite, limestone, quartz sandstone, basalt, and construction waste can all be used to process machine-made sand. But in the face of so many strong opponents, why are river pebbles still so popular?
First of all, river pebbles have a wide distribution range, rich resources, easy mining, and low mining costs, which can meet large-scale production needs.
Secondly, river pebbles are hard rocks, with a Pugh hardness level of 2-3 and a hardness coefficient of f=10-15. They are hard and have strong compression, wear and corrosion resistance.
When river pebbles are used as raw materials for processing machine-made sand, the amount of stone powder is relatively small during the production process, and the material is stable, the performance is good, and the quality of the finished product is easy to control. Therefore, the machine-made sand processed by river pebbles has excellent quality and stable performance. It is the preferred construction sand for high-rise buildings, highways, municipal engineering, water conservancy and hydropower, bridges and other infrastructure.
02. River pebble sand production line
The advantages of river pebbles themselves are the reason for their popularity, but if you want to process high-quality fine machine-made sand, it is also particularly important to choose the right production equipment!
Jaw crusher for front-end crushing: The jaw crusher has a relatively high crushing force and crushing ratio, and is the main component of the production line. In addition, the jaw crusher is better in wear resistance, the corresponding maintenance cost is lower, and the range of materials processed by the jaw crusher is wider.
Cone crusher for fine crushing: Cone crusher is suitable for processing various medium-hard materials, especially for river pebbles, granite, basalt and other commonly used sand making raw materials. The finished product of cone crusher has good particle shape and high wear resistance, and is the best choice for fine crushing.
Impact crusher sand making machine: Although there are many types of equipment used for sand making on the market, such as hammer crusher, roller crusher, etc. But none of them can match the effect of impact crusher. Although it may be questioned, the technology and finished product quality of impact crusher in the field of sand making are well-founded. The impact crusher adopts the crushing principle of stone hitting stone and stone hitting iron, with relatively high production efficiency, and the wearing parts are wear-resistant, and the corresponding maintenance cost is low. Combining various characteristics, impact crusher can be used as sand making.
Sand washing machine: Sand washing machine is mainly responsible for the end work of sand making production line. It is mainly used to remove impurities such as soil on the surface of machine-made sand. Through the sand washing process, the quality of machine-made sand will be better, and the corresponding market value will be higher.
Vibrating screen: Vibrating screen is a common screening equipment. It can screen various stones and screen out finished products of different particle sizes. Generally, there are three-layer and four-layer screens, which mainly form a cycle operation with the sand making machine in the sand making production line.
Feeder, conveyor: These two are auxiliary equipment in the production line, but they are also indispensable. The feeder is generally used at the front end of the jaw crusher, and the conveyor is the connection tool between the main equipment of the entire production line.
These main equipment are combined into a sand making production line. The specific model to be adapted needs to be configured according to various requirements such as production capacity, electricity consumption, and finished product particle size.
03. Issues that should be paid attention to when making river pebbles sand
1: Blockage problem of sand making machine
1. Feeding speed is too fast and overload of feed is added, which is easy to cause blockage. Users should equip sand making machines with corresponding production capacity according to the production volume of their own production lines, and feed them evenly.
2. The discharge pipe of the sand making machine is not smooth or blocked, and feeding too fast will block the air outlet of the machine, thereby affecting production.
3. The broken and aged hammers of the sand making machine, the closed and broken screen holes, and the high water content of the crushed stones will cause the sand making machine to be blocked. The broken and severely aged hammers should be replaced regularly, and the screens should be inspected regularly.
2: Maintenance issues of sand making machine
1. After the river pebble sand making machine works for 400 hours, an appropriate amount of grease should be added. After 2,000 hours of operation, the spindle assembly should be opened to clean the bearings. If it works for 7,200 hours, it will replace the new bearings.
2. The sand making machine should pay attention to daily maintenance. The sand making machine needs to be shut down regularly and the internal wear of the sand making machine should be observed regularly. If it is worn, it should be replaced or repaired in time. In addition, it should be noted that in the normal operation of the sand making machine, the observation hole should not be opened to avoid dangerous accidents.
3. The tension of the transmission V-belt should be properly adjusted to ensure the grouping and matching of the V-belts so that the length of each group is as uniform as possible. The current difference between the two motors should not exceed 15A.
3. Production safety issues
1. Strengthen the iron removal of the ore. Non-crushed materials (such as drill bits) falling into the working chamber will block the machine and cause a shutdown. Therefore, an iron removal system should be installed in front of the sand crusher.
2. During the work process, since the sand making machine is a high-speed running equipment, special attention should be paid to safety. Workers should stay away from the equipment and wear labor protection supplies.
3. If the machine needs to be repaired and maintained, it is necessary to turn off the power first and wait until the machine stops completely before operating the next step.
