River pebble sand making machine River pebble roller crusher, also known as river pebble roller sand making machine, is a kind of mechanical equipment dedicated to crushing river pebbles and other stones with high hardness, crushing them into sand and gravel aggregates that meet different specifications. It is widely used in the production of sand and gravel aggregates in construction, road construction, bridge engineering, as well as water conservancy, mining and other related industries, and is used as primary crushing or secondary fine crushing equipment.
This kind of equipment is mainly designed based on the principle of roller crushing, and has the following detailed introduction:
Basic structure and working principle:
The river pebble roller crusher consists of a pair of rollers made of high hardness and wear-resistant alloy that rotate relative to each other to form the core crushing unit, usually one roller is fixed, and the other can be adjusted hydraulically or mechanically to control the discharge particle size.
The material is fed from the inlet, passes between two rollers rotating in opposite directions, and crushes due to strong extrusion and shearing action. The roller gap can be adjusted to ensure that the crushed sand and gravel particle size meets the preset standard.
Main features: Efficient crushing: The roller crusher has a high crushing efficiency and is suitable for materials with high hardness such as river pebbles.
Adjustable particle size: By accurately adjusting the roller spacing, the discharge particle size of sand and gravel can be controlled to meet the needs of different uses.
Wear-resistant and durable: The roller skin made of wear-resistant alloy materials such as high chromium and high manganese has strong compression and wear-resistant performance, which prolongs the service life of the equipment.
Wide range of application: not only for river pebbles, but also for pebbles, granite, limestone and other rocks of various hardnesses.
Automatic control: Some advanced models of roller crushers have automatic control systems, which can be remotely controlled to achieve intelligent management and improve production efficiency and safety.
Small footprint and moderate investment costs: For small and medium-sized enterprises, this type of equipment has a relatively small footprint, relatively low initial investment and operating costs, and obvious economic benefits.
