Crushing Combination Solutions for Different Stone Materials

Before configuring the crushing and sand making production line, we must first figure out the raw materials that need to be crushed, such as its size, hardness, humidity, etc.

In addition, we must clarify our own requirements for output and finished product particle size and type. This will provide the necessary scientific basis for the later configuration of suitable types of crushers and sand making machines.

For example, if a hammer crusher is selected for hard rock, the direct consequence is that the hammer head will wear out quickly and the cost of replacing accessories will be high; and the disadvantage of choosing a cone crusher for soft rock is the high cost of equipment investment and subsequent maintenance.

Solution for stone production line and sand making line

The common configuration of a complete stone production line generally uses two-stageand three-stage crushing pro sses. Most
gravel plants usually use two closed-circuit process, that is, the secondary crusher and the screening equipment form a closed
circuit, ensuring that the product size can meet the requirements of sand and gravel aggregate.
The general configurations of the equipment are as follows.

1. Vibrating feeder+ jaw crusher+ impact crusher+ belt conveyor+circular vibrating screen:
   2.Vibrating feeder+ jaw crusher+ cone crusher+ belt conveyor+vibrating screen;
2. Vibrating feeder+ jaw crusher+ impact crusher+sand making machine+belt conveyor+circular vibrating screen

Sand making production line consists of a vibrating feeder, a Jaw Crusher, a Cone Crusher, an Impact Crusher (sand-maker), a vibrating screen, sand washer (sand classifier), a belt conveyor, a water treatment system and centralized electronic control system. We could also add a dust separator to the line to meet the specific requirements of our clients. We could assemble the production line according to the requirements of various processes to ensure the line has the best performance.

Solution for soft and less abrasive sand and gravel aggregates

Generally, it is divided into feeding, crushing, screening and conveying. The raw materials are conveyed to the vibrating feeder through the silo, and then conveyed to the first crushing equipment for coarse crushing by the vibrating feeder. The crushed materials are conveyed to the second crushing equipment (fine crushing) by the belt conveyor.

After crushing, the materials are conveyed to the circular vibrating screen for screening by the belt conveyor. The materials larger than the required size are returned to the second crushing for further crushing. The materials screened by the circular vibrating screen are finished materials.

If the particle shape is not good enough, you can add a vertical shaft impact sand-making machine for shaping. In this way, the particle shape of the crushed materials will be more rounded and the effect will be better.

Solution for hard and highly abrasive sand and gravel aggregates

Large hard rock materials are fed evenly to the vibrating feeder through the silo, and then enter the jaw crusher for the first crushing.
The coarsely crushed materials are screened by the vibrating screen as required and then conveyed by the belt conveyor to the cone crusher for the second medium and fine crushing.

After medium and fine crushing, the circular vibrating screen is used for screening, and the larger particles are returned to the cone crusher for crushing again. At this time, the required sand and gravel aggregates can be obtained.

If sand making and shaping are required, the materials that meet the requirements are put into the sand-making machine for further crushing and shaping. If the materials need to be cleaned, a sand washing machine can be added for cleaning. Finally, the materials that meet the requirements are classified and packaged according to different particle size ranges.

Here we take common minerals of quartz, cobblestones, sandstone, granite and limestone as examples to recommend the configuration of sand production line for you.

Quartz

• Mohs hardness: 7-7.5
• Density: 2.64g/cm³-2.71g/cm³

Quartz is a hard, wear-resistant, chemically stable silicate mineral, the main component of which is silicon dioxide. It is an important industrial mineral raw material. Generally, after crushing and sand making, it is used in glass, building materials, ceramics, and even high-tech electronics industries.

• Quartz sand production line
• Output: 30-45 tons per hour

Equipment configuration: silo + two fine jaw crushers + sand-making machine + vibrating dewatering screen + sand washing machine + fine sand recovery machine + belt conveyor

Քարեր

• Մոհսի կարծրություն՝ մոտավորապես 7
• Նյութի առավելություններ՝ բարձր կարծրություն, ուժեղ ճնշման դիմացկունություն և արհեստական ավազի ու խառնարանի արտադրության հիմնական նյութ:.

Քարերը միլիոնավոր տարիներ շարունակ լեռների ու գետերի հարվածների և հոսող ջրի տեղափոխման արդյունքում ստացված սայլաձև կարծր մարմիններ են: Դրանց հիմնական բաղադրիչը սիլիցիումի օքսիդն է, իսկ դրանցից ստացված արհեստական ավազն ու խառնարանը բավարարում են տարբեր վայրերում արհեստական ավազի ու խառնարանի պահանջները:.

• Քարերից ավազի արտադրության գիծ

Sandstone

• Mohs hardness: 2

Sandstone is a sedimentary rock, mainly composed of sand particles, of which the sand content is greater than 50%. Most sandstones are composed of quartz or feldspar, and are widely used as a building stone.

• Sandstone sand production line
• Output: 60-80 tons per hour

Equipment configuration: silo + vibrating feeder + jaw crusher + impact crusher + sand making machine + dewatering screen + sand washing machine + fine sand recovery machine + belt conveyor

Granite

• Mohs hardness: 7-8 (the hardness of granite varies in different regions)
• Material advantages: Granite is known as “rock”. When the product needs to withstand wind and rain or needs to last for a long time, granite is generally chosen.

Granite has a hard and dense texture, high strength, weathering resistance, corrosion resistance, wear resistance, low water absorption, and beautiful color can be preserved for a long time. It is a good material for construction. Granite resources are abundant, mining costs are low, and product value is high.

• Granite sand production line
• Production: 80-130 tons per hour

Equipment configuration: silo + 2 jaw crushers + vibrating dewatering screen + cone crusher + sand washer + fine sand recovery machine + belt conveyor

Limestone

• Mohs hardness: 3-4

The Mohs hardness of limestone is 3, medium-low hardness. After simple processing, the improvement and expansion of application fields will also lead to the increase of its unit economic value. Generally, the simplest one is the limestone sand production line.

• Limestone sand production line
• Production: 100-150 tons per hour

Equipment configuration: silo + vibrating feeder + jaw crusher + impact crusher + sand making machine + vibrating dewatering screen + sand washing machine + fine sand recovery machine + belt conveyor
