The roller crusher is widely used for crushing high hard and medium hard materials in such industrial departments such as metallurgy, building material and refractory. It has the features of low noise, little powder dust, reliable performance and convenient maintenance.
The Inner Structure of Roller Crusher:
The main structure of the wheel gearing is composed of fixed roller, movable roller, drive shaft, machine box, chassis, cover piece and long gear cover. The motive power of the machine comes from the V-belt pulley of the electromotor, and a pair of middle reduction gear will make the fixed roller rotate, and then a pair of long gear drive on the other side of the fixed roller will drive the movable roller, and the two rollers perform relative movement to squeeze the materials.
The adjustment of discharging granularity: There is a wedge-shaped or gasket adjustment device between the two rollers, and on the top of the wedge-shaped device, there is an adjusting bolt. When the adjusting bolt pulls up the wedge, the wedge will lift the movable roller from the fixed roller, so that the gap between the two rollers will become large, and the discharging granularity will become large. When the wedge goes down, under effect of the pressure spring, the gap between the two rollers will become small, and the discharging granularity will become small. The gasket device adjusts the discharging granularity through increasing and decreasing the number or thickness of the gasket, and when the number of the gasket increases, the gap between the two rollers will become large and the discharging granularity will become large; when the number of the gasket decreases, the gap between the two rollers will become large and the discharging granularity will become small.
The whole machine is made of high-quality wear-resistant materials, especially the grinding roller, the grinding roller can be used repeatedly, and the failure rate is low, which can bring long-term benefits to the user.
2. Easy to adjust the fineness of discharge.
The fineness of the discharge of the roller crusher can be adjusted by adjusting the wedge block or gasket between the two rollers to easily obtain the desired finished grain size.
3. There are many applicable materials and a wide range.
It can be used in mineral processing, chemical, cement, refractory materials, abrasives, building materials and other fields to treat minerals such as weather fossils, rare earths, iron filings, fly ash, peat, coal, yellow sand, mineral sand bentonite.
4. More broken and less abrasive grain shape is good.
By reducing the particle size and improving the quality of the crushed minerals, it is possible to achieve multiple crushing and grinding, improve the shape of the finished product, improve the crushing capacity, and achieve the goal of high productivity and low energy consumption.
