Double-roll crusher, also known as double-roll crusher, double-roll crusher, etc. The double-roller crusher produced by Zhongxiang Machinery is mainly used for the medium and fine crushing of medium-hard and soft ore. The double-roller crusher has a simple structure and less excessive crushing. The tooth profile, size and arrangement of the roller surface can vary with the material properties. This article introduces the structure and optimization of the double roller crusher!
1. Double roller crusher structure
Double-roll crusher is mainly composed of rollers, roller support bearings, compression adjustment device and driving device. The driving mechanism is composed of two motors. The motor is driven by a V-belt to drive the pulley, drag the drum, and rotate in the opposite direction. When smashing materials, the materials pass through the drum from the feed port and are crushed by rolling, and the crushed products are discharged from the bottom of the chassis.
2. Optimization and improvement of double roller crusher
(1). The power input shaft of the double-roll crusher is connected to the power source through gear couplings, hydraulic couplings and hard-tooth surface reducers; hydraulic couplings and gear couplings are installed on the crusher respectively Inside the protective cover on the outdoor base.
(2). Both ends of the roller shaft of the double-roller crusher structure respectively extend out of the crushing cavity, and are connected with the rolling bearing installed in the bearing seat of the base.
(3). On the premise of inheriting strong crushing force, the improved double-roll crusher can prevent the crushed materials in the crushing chamber from entering the supporting bearing cavity, greatly reducing maintenance and operating costs, and improving the working reliability of the double-roll crusher.
A wedge-shaped or gasket adjusting device is installed between the two rollers of the double-roll crusher, and an adjusting bolt is installed on the top of the wedge-shaped device. When the adjusting bolt pulls up the wedge, the wedge pushes the movable roller away from the fixed wheel, that is, the gap between the two rollers becomes larger, and the discharging granularity becomes larger. When the wedge descends, under the action of the compression spring, the gap between the two rollers becomes smaller, and the output particle size becomes smaller.
3.The price of double roller crusher
The crushing roller of the double-roll crusher is easy to wear, and the maintenance and replacement cost in production is very high. Therefore, our company surfacing hard alloy on its surface to make it wear-resistant, heat-resistant and corrosion-resistant, which can significantly increase the service life of the crushing roller and save maintenance costs.
