Pebbled Sand Making Machine Has High Efficiency And Energy Saving Due To Its Uniform Size And Compressive Strength
Aug 08, 2018

Cobblestone sand making machine is a special equipment for producing sand and stone for building. The sand has uniform grain size and high compressive strength, which is more in line with the high standard of construction sand requirements than natural sand and hammering sand. It is a jaw crusher, DVSI sanding machine, vibrating screen and sanding machine, and connected with a belt machine into a line. The production line adopts the high-speed rotating roller to throw the stone material at the linear speed of 76m/s and collide it on the wear resistant liner, forming the crushing principle of stone striking stone and stone striking iron. Ensure the whole process flow smooth, reliable operation, efficient energy saving, than traditional equipment energy saving 50%.


The performance characteristics of

1. Suitable for large-scale production with a capacity of 50-300 tons/hour.

2. The production cost per ton of finished sand and gravel is only 3/5 of that of the conventional production line.

3. High degree of production automation, low energy consumption and large crushing ratio.

4. The payback period is short, and the investment can be recovered within 4-5 months.

5. With shaping function, the product is cube shaped.

6. The finished products have good granularity and conform to the national sand standards.


The working principle of

Pebbles sand making machine is ore by feed into the mouth, and sliding down the sieve plate, oversize ore in the process of falling by high speed rotating rotor of carbide hammer on the break, and at high speed along the tangent direction to fly to the first block cavity lining plate, plate and the ore strike back again with the rotor out behind other ore collide with each other, make ore continue to be broken, the material into the first crushing cavity and the rotor plate hammer impact breakage and then into the second crushing chamber to crushing, the material in the crushing cavity broken not only formed the material of broken, also completed the material cavity plastic, until the particles into the required size, The final formed sand is discharged from the outlet. It can be seen from above that the work of cobblestone sand making machine is to crush the ore with the principle of stone, which has selective crushing effect, and the particle size of the crushing product is relatively uniform, and the shape is mostly cubic stone. It is widely used in bridge construction, highway construction, dock construction and airport construction.


The cobblestone sand making machine is mainly suitable for the current artificial sand industry, and it is an ideal model for upgrading the rod grinding sand making machine, impact sand making machine and straight-through sand making machine.

The characteristics of

The characteristics of small size of discharge material, less dust, uniform size, high productivity, long life of hammer head, small matching power, change from three-stage crushing to two-stage crushing, simple structure, stable operation, convenient maintenance, etc.


Range of application

1. Artificial sand of river pebbles, mountain rocks (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, corundum, talc, olivine, feldspar, fluorite, and stone chips.

2. Production of building aggregate, highway fabric, bedding, asphalt concrete and cement concrete aggregate.

3. Crushing technology of the grinding front in the mining field, crushing materials in the building materials, metallurgy, chemical engineering, mining, refractory materials, ceramics, cement, abrasive and other industries.

4. High abrasion and secondary disassembly and crushing; desulfurization, steel slag, construction waste breaking and other environmental protection projects in thermal power and metallurgy industries.

5. Production of glass raw materials, quartz sand and other high-purity materials.

6. Water conservancy and hydropower, high-grade highways, expressways, high-speed railways, passenger dedicated lines, Bridges, airport runways, municipal engineering, high rise buildings' mechanical sand production and stone shaping.

Fine crushing and rough grinding of iron ore, copper ore, gold ore, wood ore, lead and zinc ore, tungsten ore, manganese ore and other special, medium and abrasive materials.
