1. Introduction to roller crusher equipment
The roller crusher is also called the double roller crusher, the river pebble sand making machine, which uses two motors to drive two auxiliary rollers to extrude and grind the material. The roller crusher is suitable for fine crushing operations with a feed particle size of less than 80mm and a finished product particle size of 50-20mm. For example, the use of pebbles and construction waste to make artificial sand; mining fine crushed iron ore and quartz stone; Crushing raw materials for the ceramic industry. The roller crusher has the advantages of small size, large crushing ratio, adjustable discharge particle size, low operating cost, reliable work, low noise, simple structure and convenient maintenance, and can be widely used in building materials, refractories, cement, metallurgy, chemical industry, electric power, coal mining and other industries for brittle and toughness material processing. The roller crusher can be used for crushing and fine crushing of various ores below high hardness in mineral processing, chemical, cement, building materials and other industrial sectors.
The roller crusher is mainly composed of rollers, roller support bearings, pressing and adjusting devices and driving devices.
Second, the working principle of the roller crusher
The roller crusher will crush the material through the feeding port into the two rollers, extrusion and crushing, the finished material will fall naturally, in case of hard or unbreakable objects, the roller of the roller crusher can be automatically retreated by the action of hydraulic cylinders or springs, so that the roller gap increases, and the hard or unbreakable objects fall, so as to protect the machine from damage. The two rollers rotating in opposite directions have a certain gap, and the discharge particle size of the product can be controlled by changing the gap. The double-roll crusher uses a pair of round rollers that rotate in opposite directions, and the four-roll crusher uses two pairs of round rollers that rotate in opposite directions for crushing operations.
Roller crusher, referred to as roller crusher or roller crusher, is a relatively old-fashioned crushing equipment, which has undergone countless upgrades and transformations, and the manufacturing process is more mature. Now the new launch has hydraulic roller crusher, double tooth roller crusher and other roll crusher equipment. The structure of the equipment is simple, the phenomenon of over-crushing is less, the tooth shape, size and arrangement on the roller surface can be changed with the nature of the material, and the medium and soft ore can be crushed in medium and fine ore, such as the sulfuric acid plant usually uses a hammer crusher to crush the pyrite ore once, so that the diameter reaches 20~30mm, and then enters the double-roll crusher for secondary crushing, so that the diameter of the ore reaches less than 5mm, and meets the requirements of the boiling furnace.
3. How much is a roller crusher?
When it comes to the price of the roller crusher, there is actually no standard price, because as mentioned earlier, the equipment model that meets the standard is not single, so the price is not fixed, but one thing is for sure, the price of this type of roller crusher will not be too expensive, and the purchase of equipment in the professional Dingbo heavy factory, quality assurance, the price will be more favorable, more assured!
