Low Noise Dual Rotor Hammer Coal Crusher Anti Clogging Design For Sticky

The anti-clogging double rotor hammer crusher is an upgraded customized model targeting the common  points of traditional crushers such as screen blockage, serious hammer wear and difficult maintenance when processing high-humidity and sticky materials. Breaking the conventional grate plate structure, it adopts a unique no-screen bottom design, thoroughly solving the blocking problem caused by wet materials adhesion and accumulation. Equipped with dual opposite rotating rotors and combined wear-resistant hammer structure, it realizes dual high-efficiency crushing of materials. This machine does not require screen gap adjustment, and the finished particle size is controlled by adjusting the rotor operating gap, which is flexible and convenient. It is specially optimized for wet coal gangue, raw coal with high moisture content, sludge-containing construction waste and other difficult-to-crush sticky materials. With the advantages of no blockage, low comprehensive wear, convenient maintenance and wide material adaptability, it is the exclusive professional equipment for coal chemical industry, solid waste recycling and wet raw material processing projects.

The dual rotors are driven by independent power units to rotate oppositely at a stable speed, forming a closed flexible crushing cavity. After high-humidity and sticky materials enter the cavity, they are subjected to dual-rotor high-speed impact, shear crushing and mutual material collision crushing. Different from traditional screen-type crushers that rely on grate plates for filtering and discharging, the no-screen bottom structure cancels the bottom barrier, and qualified fine materials are discharged smoothly by gravity after crushing. For sticky and wet materials that are easy to adhere, the dual-rotor alternating impact mode continuously cleans the cavity without material dead corners and accumulation. Bulk materials are refined to qualified granularity through multiple cycles of impact and grinding, realizing continuous and non-blocking crushing operation throughout the whole process.

• No-screen Anti-clogging Design Cancel traditional grate plate structure, completely avoid material adhesion and blockage, and can stably crush materials with moisture content up to 15% without shutdown cleaning.
• Low Wear & Long Service Life Adopt split hammer and hammer handle structure, only replace the worn hammer head without changing the hammer handle. The movable hammer head can be reused by position adjustment, greatly reducing spare parts cost.
• Easy One-person Maintenance Equipped with electric-hydraulic opening device, the machine shell can be opened and closed effortlessly, realizing rapid replacement of wearing parts and daily inspection, saving maintenance time and labor cost.
• Strong Wet Material Adaptability It has excellent crushing effect on high-humidity coal gangue, raw coal, sludge-containing construction waste and other special materials that are difficult for ordinary crushers to process.
• Low Noise & Low Dust Operation Closed cavity circulating crushing reduces dust overflow, and the balanced dual-rotor operation lowers operating noise, meeting environmental protection production standards.

Widely used in coal preparation plants, coal chemical enterprises, construction waste recycling stations, shale brick factories and other scenarios, specially for crushing high-moisture coal gangue, raw coal, sludge-containing waste and various sticky industrial raw materials.

• Q1: What materials is this anti-clogging double rotor crusher suitable for? A1: It is specially designed for high-humidity and sticky materials such as wet coal gangue, raw coal and sludge-mixed construction waste, solving the blocking problem of ordinary crushers.
• Q2: How to adjust the finished particle size without screen plate? A2: The particle size is accurately controlled by adjusting the gap between the two rotors, with flexible adjustment range and stable finished granularity.
• Q3: Does it save operating cost compared with ordinary models? A3: Yes. The reusable combined hammer structure greatly reduces wear cost, and the anti-blocking design avoids frequent shutdown cleaning, improving production continuity and overall efficiency.
