Huashengming secondary crushers primarily include two major types: dual-stage crushers (dual-stage screenless pulverizers) and double-roll crushers. Their operating principles are based on dual-rotor relay crushing and dual-roll compression crushing mechanisms, respectively. 1. Secondary Crusher Dual-Stage Crusher Operating Principle (Core Model) Specifically engineered for high-moisture, sticky materials, the dual-stage crusher achieves efficient fine crushing through two-stage rotor series crushing. Its screenless design completely eliminates clogging issues. Dual-Rotor Relay Crushing Process: Primary Crushing: Material enters the upper rotor zone via the feed inlet, undergoing preliminary crushing through impact and shearing by high-speed rotating hammers (high-chromium alloy material). Secondary Crushing: Centrifugal force propels the partially crushed material toward the lower rotor, where it undergoes further hammer impact. Simultaneously, high-speed collisions and friction between particles create a “hammer-on-material, material-on-material” effect, achieving secondary fine crushing. Discharge Control: Crushed material exits directly through hammer gaps without screen restrictions, achieving a discharge particle size ≤3mm (80% ≤2mm). Screenless Anti-Blocking Design: Eliminates traditional screen plates, allowing wet and sticky materials (moisture content ≤15%) to pass smoothly without wall adhesion or blockages, enabling continuous operation even during rainy weather. Modular hammer design facilitates quick replacement after wear (approx. 30 minutes), minimizing maintenance costs. Applications: High-moisture materials: Coal gangue,…

Quartz stone sand making can completely adopt roller sand making machine (also known as double roller sand making machine), and this equipment is widely regarded as one of the ideal choices for processing high hardness quartz stone because of its unique working principle and performance advantages. 1. The applicability of roller sand making machine in quartz stone sand making Working Principle Suitable for High Hardness Materials Roller sand making machine applies high pressure squeezing and shearing force of 50-200MPa to the material through two rollers rotating in opposite direction (usually one fixed and one adjustable). Quartz stone has high hardness (Mohs hardness grade 7), traditional impact crushing is easy to lead to excessive wear or uneven particle shape, while the slow crushing method of the roller machine can effectively reduce excessive crushing and maintain the integrity of the particles. Undesirable materials are crushed between the rolls to ensure uniformity of the finished product. Excellent finished product quality Controllable particle size: By adjusting the roll spacing (0.5-40mm) through hydraulic or wedge system, the particle size of the discharged material can be accurately controlled to meet the grading requirements of construction sand (e.g. 0-5mm fine sand or coarse aggregate). Three-dimensional particle shape:…
