Double roller crusher, also called double roller sand making machine, is mainly used for fine sand-making. There are many sand plants to pick it as a crushing machine for its outstanding advantages in recent years. It is capable of handling both dry and wet materials, and performs well in handling more than two hundred kinds of materials including pebbles, river pebbles, quartzite, steel slag, glass, and so on. Double roller crusher also operates well in sand-making with adjustable discharge size. When the size of feeding material is less than 8cm and the discharge size is less than 5mm, the finished product rate can reach about 90%. The wear parts of the double roller crusher are also very durable with the long service time for more than 1 year. And if the feeding materials is soft, its service time even reaches to three years without replacement. Furthermore, the double roller crusher has also been improved in recent years. Compared with the previous manual spring double roller crusher, the new large-size double roller crusher are equipped with direct-connected drive structure, semi-automatic and fully automatic hydraulic equipment, which greatly optimizes the productivity of the double roller crusher. Different manufacturers produce double roller crushers of different quality with different accessories. When it comes to the price, such as small double roller crusher 2PG400*250, with production capacity of 2-10 tons per hour, its price is generally more…
Double roller crusher makes up for the lack of natural sand. Double roller crusher, as a great tool of sand-making, is highly favored by our customers. Many directors set up sand plants would like to purchase the double roller crusher for its convenient operation, less wearing parts and the adjustable discharge size. Double roller crusher is widely used in all walks of life due to its strengths. However, there exists many people who wonder what materials are suitable for crushing by double roller crusher? Then, let’s talk about this question now! Double roller crusher is suitable for crushing solid and medium or fine materials with compressive strength less than 250Mpa and water less than 35%, such as river pebbles, pebbles, iron ore, quartzite, potassium feldspar, sodium feldspar, limestone, silicon, barite, basalt, granite, steel slag, cement clinker, construction waste concrete), shale, quicklime, coal, coke, clay, bentonite, chemical raw materials and so on. With the adjustable gap between the two rolls of the double roller crusher, the discharge size can be adjusted to meet the customers’ various production needs, which earns more popularity than other crusher equipments. The gap between the two rolls of the double roller crusher can be adjusted flexibly. When the size of feeding material is less than 8cm and the discharge size less than 5mm, 3mm, 1mm, the finished…

The tanks on the back of the hydraulic roll crusher is nitrogen accumulator, which has a nitrogen airbag inside. It can effectively protect the oil cylinder and oil pipe from instantaneous high pressure damage,and it also plays a role in maintaining pressure of the roller.
Hydraulic cylinder heating is a common problem. After years of testing and improvement, our hydraulic roll crusher is equipped with a complete water cooling system to cool the hydraulic cylinder and achieve 24-hour continuous operation of the equipment.
Our roll crusher has a fully automatic hydraulic system that can be adjusted through a PLC control cabinet. One click operation, convenient and simple.
Our hydraulic roll crusher has a balanced flashback function. When the iron block enters the roller crusher, the two rollers will automatically retreat through the hydraulic system. After the iron block is discharged, the two rollers will immediately return to the original position to continue production.
The roller sand making machine has the lowest powder content among all sand making equipment.It don’t have the sieve like the hammer crusher,the material is directly discharged after crushing.
Double roller sand making machine is low speed and high torque equipment, and the produced sand has a reasonable grading and low powder content. If there are no impurities in the raw material, there is no need to wash it.
