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.
Because the roll crusher is a low speed and high torque equipment, its motor power is smaller than other equipments with the same output.The power consumption for each ton of sand produced is within 2KW.
The appearance of grooves is directly related to the incorrect feeding method and the raw material of the roller skin.We can add a vibrating feeder in front of the roller crusher to continuously and evenly feed the material,then the wear degree of the roller surface will be the same, and there will be no grooves.
Firstly, our roller skin material is our patent material,which is Mn18Cr2 and containing other rare metals. Diffirent with other ordinary roller,our roller skin is more durable and 3-5times using time of them.According to customers raw material,the using life can reach 3years.
The roller skin using life of double roller crusher can reach 3 year.Our roller skin material has a national patent，which is more durable and thicker.
We have more than 20 models of double roller crusher, including diffirent types such as fully hydraulic roller crushers, spring roller crushers, shaft-driven and belt-driven.We can suggest you the most suitable model according to your raw material and production needs.
There are more than 20 models of roll crusher for sale,with the capacity of 5-400 t/h, the finished product rate is up to 80%.As the manufacturer,we can suggest you the most suitable model according to your requirement.
A: Single motor roller crusher is driven by one motor to drive the two rollers, whether it is idle or working, the load is very high and must be driven by a high-power motor. It has high power consumption and low efficiency, and belongs to the old-fashioned roller crusher. As a obsolete product, it is rarely used nowadays. But double roller crusher is the upgraded version, which is driven by two low power motors and equipped with two hard gear reducers to achieve high torque crushing.The design is more reasonable, not only reducing energy consumption, but also improving production efficiency.
Smooth roll crusher’s discharge is fine, mainly used for sand making or mineral processing discharge requirements in 0-10mm, toothed roll crusher general discharge about 10-100mm, crushing low and medium hardness ore, discharge requirements of particles more powder less use requirements, like coal washing plant crushing coal block, carbon plant crushing coke and other industries; general size of the tooth shape determines the size of the discharge.
