Four Roller Crusher Product Description
Four-roller crusher is suitable for solid materials with compression strength less than 300Mpa and water less than 30%, and it is required to have fine and medium crushing process with large crushing ratio. Such as crushing iron ore, quartzite, potassium (sodium) feldspar, limestone, river pebbles, silicon, barite, basalt, granite, steel slag, cement clinker, construction waste (concrete), shale, lime, coal, coke, water slag, clay, gypsum, bentonite, fertilizers, chemical raw materials and other solid materials. It has characteristics by low maintenance cost, large crushing ratio, low water requirement, low power consumption, reliable performance, low dust and low noise.
Four rollers crusher is equipped with four crushing rollers, you can choose toothed , resurfacing welded, and flat roll surface , suitable for feeding size less than 90mm, finished product size 0.3-10mm medium and fine crushing process.
If the compression strength of the material is more than 200Mpa, it is recommended to choose the aggravated model. 2 transmission modes to choose according to the your requirements: V belt and coupler transmission (hard link). For the mine with low power you can choose diesel or gasoline engine as power.
Four Roller Crusher Working Principle
The four-roller crusher utilizes four high-strength wear-resistant crushing rollers, which rotate relative to each other to produce high squeezing and shearing force to crush materials. After the material enters the gap between the upper two rollers (V-shape crushing chamber), it will be squeezed and sheared by the relative rotating of the two rolls, the material will be squeezed and sheared for the first time (coarse crushing), and then it will enter into the relative rotation of the lower two rollers, and then squeezed, sheared and grounded by the lower two rollers (fine crushing) into the required partle size from the outlet.
