Pebble, a kind of natural stone, is mainly from the pebble mountain which is raised from ancient riverbed because of the earth's crust movement millions of years ago. The formation of pebble undergoes continuous extrusion and friction of flood and running water. Pebble is usually smooth under action of wave and flowing water and buried under the earth surface with sand.

The river pebbles resource in China is abundant, the main chemical composition of gravel is silicon dioxide, secondly it is composed by small amount of iron oxide and trace elements such as manganese, copper, aluminum, magnesium and compound, it has natural stone features of hard quality, compression, wear-resistance and anticorrosion, it is an ideal material for building application. Currently gravel sand making production lines are continually built all over the country, which guarantee the supply of quality aggregate for national construction projects.

The coarsely crushed materials are screened by vibrating screen and then conveyed by belt conveyor to cone crusher for medium crushing. The crushed stones are conveyed to the vibrating screen through a belt conveyor to sieve out different specifications of stones. The stones that meet the requirements of the customer's particle size are conveyed to the finished product pile through the belt conveyor. The cone crusher crushes again, forming a closed circuit cycle.

Note: For the sand powder with strict requirements, a sand washing machine can be added behind the fine sand. The waste water discharged from the sand washing machine can be recovered by the fine sand recycling device. On the one hand, it can reduce environmental pollution, and on the other hand, it can increase sand production.

The sand making production line has the features of reasonable configuration, high automation, low operation cost, high crushing rate, energy saving, environmental protection, high capacity and easy maintenance, the manufactured sand conforms to national standard for construction sand, uniform grain, excellent particle size, well graded.

The equipments of the sand making production line are configured in accordance with the specification and output as well as application of the sand, we provide solution and technical support, and design the process according to the production site of customer, we make every effort to provide the most reasonable and economic production line for customers.

4. SANME can provide technological process plans and technical support according to the actual requirements of customers, and can also design non-standard supporting components according to the actual installation conditions of customers.

river pebble processing-crusher production line of large mining factory price

The main chemical composition of the river pebble is silica, followed by a small amount of iron oxide and trace amounts of manganese, copper, aluminum, magnesium and other elements.It is an ideal building material with hard quality, natural stone properties resistant to pressure, abrasion and corrosion.

The river pebble production process uses gravel of 0-40mm as raw material.Using vertical shaft impact crusher (sand making machine) on the production line configuration,this crusher is a new sand making machine of Dewo. It is characterized by high crushing efficiency (with fine crushing and coarse grinding function), simple structure, convenient installation and maintenance, low running cost and excellent product granularity (in cube and needle-like content less).

There are river pebble resources, which vary from place to place. Therefore, when configuring the equipment, the wear resistance of the solution should be put in the first place. Large particle size can refer to the crushing of granite and basalt; small particle size needs to be pre-screened to reduce production cost;

Take the river pebbles below 200mm as an example:The material is pre-screened in the raw material warehouse through the feeder and belt conveyor to the 1# vibrating screen. The material larger than 40mm enters the cone crusher to crush, and the 5-40mm enters the vertical impact crusher for crushing,0-5mm enters the sand washing machine, and the finished product is directly discharged after cleaning.The crushed product of the cone crusher enters the 2# vibrating screen and is screened.The return cone crusher larger than 40mm breaks and breaks again, forming a closed loop,less than 40mm into the vertical impact crusher crush.The material from the vertical impact crusher enters the 3# vibrating screen,more than 20mm returning vertical impact crusher to break, forming a closed loop.Material less than 20mm is transported to the finished product pile via a belt conveyor,according to the cleanliness of the raw materials, it is considered to send the materials of 0-5mm to the sand washing machine for cleaning.

The sand production line has reasonable configuration, high degree of automation, low operating cost, high breaking rate, energy saving and environmental protection, large output and easy maintenance. The machined sand produced meets the national construction sand standard, the product has uniform particle size, good granular shape and reasonable gradation.

Remarks: The equipment configuration of the sand production line is mainly determined by the customers specifications for the sand and the output and the use of the sand.We provide solution and technical support, configure the process according to the customers production site, and strive to achieve a reasonable and economical production line for customers.

HVI sand making machine is one of the most advanced sand making equipment, whose structure has been upgraded, working performance further improved. It is suitable for making and shaping sand, and both capacity and quality have been greatly improved in HVI series sand maker. And it is the new rising star in sand and stone equipment, which can be used to crush metal and non-metal ores, process building materials, make and shape sand.

It adopts a deep cavity which makes more throughput of materials and realizes two feeding methods of central feeding and sides feeding, to reduce the downtime effectively and improve the working efficiency greatly.

The combination of new upper and lower peripheral shields are designed to reduce the wear of the materials, and there are three throwing heads, which can be replaced after being worn, which greatly improves the service life of the wearing parts and reduces the frequency of replacement.

The energy-saving and environmental motor is equipped with reasonable coordination between the components. In the production process, the dust is less spilled and the noise is low, which meets the requirements of green production.

The motor drives the spindle of the bearing cylinder to rotate at a high speed, and the rotor rotates with the spindle at a high speed. The material entering the impeller is accelerated by the impeller and then sprayed into the crushing chamber, colliding and grinding with other materials in the crushing chamber, so as to achieve continuous crushing and shaping of the material. The processed material is discharged from the lower part of the body. The crushing method is "stone -hitting-stone principle", and the method is mainly applied to the shaping and crushing of stone.

In addition, the equipment is also equipped with a "stone-hitting-iron" crushing method. Unlike the stone -hitting-stone principle, the material is ejected from the rotor and collides with the counter-attack block installed in the crushing chamber to finish the sand making process. This crushing method is mainly suitable for crushing process

Introducing German and American innovative sand making machine production technology, and combining with years of sedimentation experience of the manufacturer, HVI sand making machine is created, which mainly consists of feeding port, rotor, frame, pulley, control device, liner, casing, motor, discharge port and other components.

The new structural design enables it to have a wider range of applications and broaden the value of market applications. It can process various stones such as limestone, pebbles, quartz stone, marble, dolomite, granite, iron ore, etc. The HVI sand making machine is good equipment for the sandstone material factory to establish a production line.

Since the end of 2017, the Vietnamese government has imposed restrictions on natural sand mining because the wild mining of natural sand in Vietnam has led to the exhaustion of sand and gravel in recent years, and Vietnamese experts estimate that natural sand in Vietnam will be exhausted within five years.

In April 2018, Mr. Phan of Vietnam posted a message on the website, saying that he would like to know about the river pebble sand production line of the HXJQ Mining Machinery. After receiving the message, our engineers immediately contacted Phan, and after learning about his project, the engineer introduced a 200 TPH river pebble sand production line to him.

Nowadays, this production line has been officially put into production for more than a year. Due to the lack of natural sand in Vietnam, the artificial sand market is at a rapid increase for a period of time.

In January of this year, Mr. Phan gave feedback to our after-sale service department. He said: "Thanks to the engineers of the HXJQ Mining Machinery for the production line. This production line has run smoothly in the past year, the failure rate has been extremely low, and the operation and daily maintenance have been very simple. At present, the artificial sand market is a very good industry in Vietnam. I will invest more projects in the future, hoping to have more and more cooperation with HXJQ." We are very happy to receive such good news, also hope that Mr. Phan will develop better and better.

HXJQ Mining Machinery as the mining machine manufacturer has committed to research HVI sand making machine for a long time and already understood the techniques of HVI sand machines. HXJQ can supply excellent equipment with cheap price and perfect after-sale service to ensure smooth production.
