The “Filter Crusher” produced by Huashengming Heavy Industry is not a standalone equipment category, but rather an integrated unit combining screening and crushing functions. It is primarily used in scenarios such as construction waste recycling, asphalt milling material processing, and mineral classification crushing.
Filter Crusher
1. Integrated Screening and Crushing Machine (Core Model)
Modular Integrated Screening and Crushing Machine
Functional Design: Combines crushing (twin-tooth rollers/counter-rotating rollers) with vibrating screens to achieve continuous operation from “feeding → crushing → screening → graded output,” reducing redundant crushing and powder generation.
Applications: Asphalt milling material recycling, construction waste sorting (e.g., concrete blocks, bricks), coal grading and crushing.
Technical Advantages:
Low Over-Grinding Rate: Optimized tooth profiles (e.g., trapezoidal, wolf teeth) utilize shear force crushing instead of impact, minimizing fine powder generation (over 30% reduction in powder rate).
Adaptability to Wet/Sticky Materials: Screenless bottom design prevents clogging, enabling processing of high-moisture content materials (e.g., post-rain construction waste).
Double-Tooth Roller Crusher (Integrated Screening Function)
Custom Tooth Profiles: Offers elongated teeth, wolf teeth, trapezoidal teeth, etc. Matches tooth profiles to material properties (e.g., brittle quicklime, ductile asphalt) to enhance crushing efficiency and particle size uniformity.
Particle Size Control: Hydraulically adjustable roll gap (1-10mm range) ensures precise output grading to 2-8mm (e.g., asphalt recycling requires 2-8mm gradation) 25.
2. Technical Parameters and Model Comparison
| Equipment Type | Representative Model | Feed particle size (mm) | Discharge particle size (mm) | Production Capacity (t/h) | Power (kW) | Applicable Scenarios |
|---|---|---|---|---|---|---|
| Integrated Screening and Crushing Machine | Custom Modular | ≤1500 | 10-200（adjustable） | 5-2000 | Depends on configuration |
Large-scale construction waste processing plants
|
| Double-Tooth Roller Crusher | 2PGY800600 | ≤40 | 2-8 | 25-40 | 22×2 | Asphalt milling material, coal |
| Two-Stage Crusher | SCF800×700 | ≤120 | ≤2（fine powder） | 60 | 55 | High-moisture coal gangue, slag |
Note: The core performance of filter crushers is “simultaneous crushing and screening,” not standalone filtration. The “integrated screen-crusher” in the table refers to large custom systems, while dual-tooth rollers/two-stage crushers are standard models with integrated screening functions.
3. Core Performance Advantages
Low Pulverization Control
Dual-tooth rollers employ “shear-force crushing” principles, breaking material along weak points to prevent over-grinding (reducing quicklime powder rate by 50%⁴). Dual-stage crushers achieve secondary crushing via upper/lower rotors, delivering uniform particle size with over 85% ≤2mm particles⁸⁹.
Wear Resistance & Maintenance Efficiency
Rollers feature high-chromium manganese steel + rare metals (patented material) for ≥2-year lifespan; Modular design enables rapid replacement of tooth plates or screens.
Intelligent Control
Hydraulic system adjusts roll gap; centralized lubrication + overload protection (e.g., hydraulic coupling) minimizes downtime for maintenance.
4. Application Scenarios & Materials
Typical Materials:
Construction Waste: Concrete blocks, bricks, asphalt millings (30% higher recycling rate).
Ore: Quicklime, coal gangue, river pebbles, granite (adjustable output size 1-3mm)
High-Moisture Sticky Materials: Sludge, clay, rain-soaked slag (clog-resistant design without screen bottom)
Industry Applications:
Road rehabilitation projects (asphalt recycling), sand production in quarries, pre-screening in mines, environmental waste treatment plants.
