DP Series Excavator Crusher Bucket

Q: Q1: What are the primary differences between the DP-25 and DP-35 crusher bucket models?

A: The DP-25 (0.7 m3m3 capacity, 2,750 kg weight) is designed for standard 20–27 ton excavators requiring 32 MPa working pressure and 180 L/min flow. The heavy-duty DP-35 (1.0 m3m3 capacity, 4,100 kg weight) is matched with 30–40 ton excavators with a wider 900 mm jaw mouth, higher hourly throughput, and operates at 25 MPa with 240 L/min flow.

Product Overview

The DP series excavator crusher bucket is a heavy-duty hydraulic jaw crushing attachment engineered for on-site reduction of reinforced concrete, demolition rubble, quarry stone, and natural rock for 20 to 40-ton excavators. Powered by a high-torque dual-motor single-shaft transmission system and US-imported hydraulic control valves, this robust hydraulic excavator crusher bucket delivers consistent crushing power with an adjustable output granulometry ranging from 15 mm to 120 mm. By crushing bulky rubble directly on demolition jobsites and recycling yards, it turns site waste into reusable aggregate and road base material without requiring external crushing plants. Built with an NM400 wear-resistant steel chassis and reversible jaw plates, the DP series provides contractors with high productivity, lower operating costs, and long service life.

Product Features

High-Torque Dual-Motor Single-Shaft Drive: Equipped with dual hydraulic motors driving a single eccentric shaft, ensuring balanced power transmission, smooth starting torque, and continuous crushing performance under high hydraulic pressures up to 32 MPa.
Premium US-Imported Hydraulic Valves: Integrates high-precision imported hydraulic control blocks to prevent pressure spikes, protect carrier excavator hydraulic circuits, and maintain steady fluid dynamics.
NM400 Wear-Resistant Steel Chassis: Fabricated entirely from high-grade NM400 abrasion-resistant steel plate with mortise-and-tenon interlocking welded joints, ensuring high rigidity and preventing structural cracking under severe impact loads.
Reversible & Interchangeable Jaw Plates: Heavy-duty manganese alloy wear jaw plates feature a symmetrical, bi-directional interchangeable design, allowing operators to flip worn plates to maximize utilization and double the wear lifespan.
Adjustable Output Sizing (15–120 mm): Quick-adjust discharge setting allows on-site operators to calibrate final aggregate dimensions from fine sub-base material (15 mm) to coarse backfill rock (120 mm).
Tier-1 Industrial Motors and Bearings: Fitted with top-tier industrial heavy-duty bearings and motors, featuring reinforced dust seals to prevent slurry and dust contamination on demanding demolition sites.

Applications

Reinforced Concrete & Demolition Recycling: Crushing concrete slabs, pillars, brick walls, and masonry on urban demolition sites, separating internal rebar cleanly for scrap recycling.
Road Construction & Trench Backfill: Crushing excavated stone and old asphalt paving directly along roadbeds or pipeline trenches to produce immediate on-site gravel and leveling layers.
Quarry & Mining Secondary Crushing: Primary and secondary reduction of extracted limestone, sandstone, river gravel, and quarry overburden at remote pits.
Tunnel & Underground Excavation: Sizing blasted rock and hard spoil inside tunnels or constrained urban spaces where mobile track crushers cannot access.

FAQ

Q1: What are the primary differences between the DP-25 and DP-35 crusher bucket models?

A: The DP-25 (0.7 $m^{3}$ m3 capacity, 2,750 kg weight) is designed for standard 20–27 ton excavators requiring 32 MPa working pressure and 180 L/min flow. The heavy-duty DP-35 (1.0 $m^{3}$ m3 capacity, 4,100 kg weight) is matched with 30–40 ton excavators with a wider 900 mm jaw mouth, higher hourly throughput, and operates at 25 MPa with 240 L/min flow.

Q2: Can the DP series jaw crusher bucket crush reinforced concrete with rebar?

A: Yes. The high crushing force easily fractures concrete blocks away from embedded steel rebar. Because of the open bucket structure and downward discharge geometry, rebar passes through freely without jamming the jaw mechanism, allowing easy separation and collection on-site.

Q3: How do operators adjust the crushed aggregate output size on site?

A: Output granulometry can be adjusted between 15 mm and 120 mm by inserting or removing calibrated shims behind the moving jaw plate. This mechanical adjustment requires no hydraulic reconfiguration and allows quick transition between fine gravel production and coarse sub-base crushing.
