A two-stage no-screen crusher is a double rotor fine crushing machine without a screen bottom. Traditional fine crushers often face clogging problems. Wet, sticky raw materials stick to the screen and stop production. The two-stage no-screen crusher removes the sieve design. It uses two rotors to crush materials twice. The first rotor breaks large stones into medium size. The second rotor hits the material again to reach fine particle output. No screen means no blockage. This machine works well for high moisture materials. Common Raw Materials For Two-stage No-screen Crusher Many crushing machines cannot handle wet feed. Even a small moisture level causes screen plugging. The two-stage no-screen crusher avoids this weakness. It can crush wet and sticky materials steadily. Key Advantages of Two-stage No-screen Crusher This crusher is widely used in brick factories, coal plants, solid waste recycling, and small mining sites. Buyers can choose different capacity models. Small capacity for workshop use. Heavy-duty models for large crushing lines. FAQ What is a two-stage no-screen crusher? It is a double rotor fine crusher without a sieve. Two rotors crush materials two times to get fine sand and powder. Can it crush wet clay? Yes. The no-screen design prevents blockage […]
A hammer crusher is a high-efficiency stone crushing machine for mining and construction industries. It delivers fine and medium crushing results with low investment costs. This equipment suits brittle and soft materials for industrial processing. What Is a Hammer Crusher A hammer crusher is a mechanical crushing device. It uses high-speed rotating hammers to strike raw materials. The machine breaks stones and ores into small particles through impact and collision. It features a simple structure and stable operation. The hammer crushing machine supports dry and wet crushing modes. It is widely used in small and medium crushing production lines. Working Principle of Hammer Crusher The working process of a hammer crusher is straightforward and efficient. The motor drives the rotor to rotate at a constant high speed. Raw materials enter the crushing chamber from the top feeding port. High-speed hammerheads strike the materials instantly. The materials crash against the liner plate and collide with each other. Repeated impact breaks large materials into fine grains. Qualified particles pass through the screen mesh and discharge out. Oversized materials stay in the chamber for secondary crushing. This circulating crushing mode ensures uniform output particle size. It improves overall crushing efficiency effectively. Key Features […]
A jaw crusher is one of the most popular primary crushing machines in the mining and construction industries. It features a simple mechanical structure, stable running performance, and reliable processing capacity. For this reason, it is widely used in quarrying, stone aggregate processing, road construction, and construction waste recycling. As the first-stage crushing equipment in most production lines, it plays a vital role in reducing large raw stone into manageable sizes for further processing. The working principle of a jaw crusher is straightforward and efficient. The machine relies on two jaw plates — a fixed jaw and a movable jaw — to squeeze and crush hard materials. A motor drives the eccentric shaft, which creates continuous reciprocating movement for the movable jaw. When raw materials enter the crushing chamber, they are compressed and ground into smaller particles. Qualified materials exit through the bottom discharge opening, while oversized stones remain inside for repeated crushing. This process ensures stable, continuous production. Jaw crushers offer strong adaptability for diverse working conditions. They can crush various raw materials, including granite, limestone, basalt, and iron ore. Multiple equipment models are available, covering small laboratory units, medium plant-grade machines, and heavy-duty industrial crushers. Users can freely […]
A double-stage screenless sand making machine crushes wet and sticky material without clogging. It uses two rotors and removes the screen mesh entirely. The result is stable output, uniform particle size, and lower maintenance. This machine is built for construction waste, recycled sand, and wet aggregate. What Is a Double-Stage Screenless Sand Making Machine? It is also called a double rotor screenless crusher. This machine belongs to the medium-fine crushing family. It solves the screen-clogging problem of traditional hammer crushers. Two rotors are stacked inside the crushing chamber. There is no screen mesh at the bottom. Material enters once and goes through two crushing stages. The machine directly produces finished sand. No secondary screening equipment is needed. This simplifies the whole sand production line. How Does the Double Rotor Crusher Work? Raw material enters the upper crushing chamber first. The upper rotor spins at high speed. Hammer heads hit the material for primary crushing. Broken material drops into the lower chamber. The second rotor strikes and grinds it again. Because there is no screen, material exits freely. Particle size is controlled by hammer gap adjustment. Users can change the gap to adjust output size. Finished sand is normally below 3mm. […]
A jaw crusher is a primary crushing machine for mining and construction industries. It breaks large hard stones into uniform small particles. This heavy-duty crushing equipment suits granite, basalt, limestone and ore materials. It is the most widely used primary crusher in aggregate production lines. What Is a Jaw Crusher? A jaw crusher relies on compressive force to crush raw stones. It has a fixed jaw plate and a movable jaw plate. The movable jaw swings repeatedly to squeeze raw materials. Continuous squeezing and grinding reduce stone size effectively. This primary crushing device features simple structure and stable performance. It supports dry and wet crushing working conditions.
