Double Tooth Roller Crusher

Core Advantages

Cutting-edge technology that sets the industry standard

High Block Rate

Uniform output with lower maintenance cost.

Combined Crushing Principle – Utilizes shearing, splitting, and extrusion for efficient material reduction.
Higher Lump Ratio – Compared with secondary crushers such as impact and cone crushers, the block rate reaches 65%–80%.
Uniform Particle Size – Produces evenly sized finished materials with reliable and convenient size adjustment.
Low Maintenance – Requires less maintenance work, reducing downtime and service costs.

Long Lifespan

Durable tooth disc with repairable design.

Low-Carbon Treatment – The tooth disc undergoes low-carbon quenching and tempering for enhanced durability.
Wear Resistance – Improved material properties ensure strong resistance to abrasion.
Weld Repairable – Severely worn areas can be repaired by welding on a single tooth roller.
Extended Service Cycle – Repairable design significantly prolongs the overall service life.

Low Energy

Optimized design for selective crushing.

Optimized Tooth Shape – The tooth roller profile is specially optimized for efficient material engagement.
Selective Crushing – Enables selective crushing to reduce unnecessary material breakage.
Reduced Power Consumption – Efficient crushing action significantly lowers overall energy usage.
Cost Efficient – Lower energy demand helps reduce operating costs.

High Utilization

Less over-crushing, higher material efficiency.

Reduced Over-Fines – Minimizes excessive powder generation in finished materials.
Higher Resource Efficiency – Improves resource utilization by approximately 15%–30% compared to other secondary crushers.
Three-Stage Adjustment – Equipped with three adjustable gap settings between the two tooth rollers.
Stable Output Size – Uses an eccentric rigid adjustment method to maintain consistent discharge particle size.

Application Scenarios

Zhongyu Dingli undertakes the construction of sand and gravel aggregate production lines with an hourly output of 100-6000 tons, and provides intelligent control systems for mines.

Guizhou 4,000 t/d Sand & Gravel Plant

The 4,000 tons per day sand and gravel production line is a newly built project designed to produce aggregates such as 12, 13, and 05 stone. Construction started in October 2017, with a total construction period of 45 days.

Anhui 1,000 TPH Aggregate Production Line

This project is a newly constructed large-scale aggregate production line completed and put into operation in 2017. The designed capacity is 1,000 tons per hour, with a maximum output reaching 1,500 tons per hour.

Hubei 10 Million Tons Aggregate Production Line

The large-scale aggregate production line in Yichang, Hubei has a total investment of RMB 60 million and covers an area of 53.73 mu (≈3.58 hectares). The project adopts a fully enclosed environmentally friendly design and is equipped with our DLPCZ1815 heavy hammer impact crusher, DLPC1220 shaping crusher, and other mining equipment.

Shandong Shuifa Wet Process Manufactured Sand Production Project

To reduce water consumption, Shandong Shuifa Ecological Environment Industry Development Co., Ltd. implemented a closed-loop water circulation system and a wastewater treatment system, enabling efficient water recycling.
