Double Roll Crusher are widely used in metallurgy, building materials, refractory materials and other industrial sectors to crush high-hard and medium-hard materials. This series of roller crushers are mainly composed of rollers, roller supporting bearings, pressing and adjusting devices, and driving devices. It has the characteristics of low noise, less dust, reliable performance and convenient maintenance.

1. Sturdy and durable, longer life.
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.

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.
