In the coal mining, quarrying, and construction waste recycling industries, crushing efficiency and operating costs directly impact the overall profitability of any project. Traditional fixed crushing lines, while technically proven, require substantial civil foundation work, long installation periods, and become immobile once the site changes or the material source shifts – leading to high material haulage costs and wasted resources. To address this industry pain point, Huashengming developed the mobile double-tooth roll crusher, which integrates the crusher, feeding system, and discharge conveyor onto a single movable platform – truly delivering on the concept of “bringing the crusher to the working face.”
Mobile Double-Tooth Roll Crusher
A coal mine customer in Shanxi Province had long struggled with this exact problem. Located in a mountainous area, the mine’s coal face advanced continuously, and stockpile points shifted frequently. A fixed crushing line would have required significant concrete foundation work and, more importantly, would have been unable to follow the advancing face. Raw coal had to be hauled over long distances to reach the crusher, driving up transport and labor costs and severely compressing profit margins. The customer urgently needed a solution that combined efficient crushing with flexible mobility.
After thoroughly assessing the customer’s operating conditions, the Huashengming engineering team custom-designed a 600×750 mobile double-tooth roll crusher. The unit features a tire-mounted chassis and integrates a raw material hopper, vibrating feeder, double-tooth roll crusher, and discharge belt conveyor into a single compact package. Upon arrival at the site, the equipment can be connected to a power source and put into operation immediately – without any concrete foundation or complex installation and commissioning.
The double-tooth roll crusher is the core of the system. Two counter-rotating toothed rolls apply a combination of compression, shearing, and splitting forces to break the material. Unlike impact crushers that shatter material violently, the double-tooth roll design operates at low speed and high torque, resulting in lower noise, reduced dust emissions, and improved energy efficiency. In addition, the equipment uses a pass‑through crushing principle: material that meets the size requirement passes directly through the gap between the rolls and discharges immediately, avoiding over‑crushing and minimizing fines generation. The tooth profile can be customized according to material characteristics to suit different crushing needs.

In this specific application, the crusher processes raw coal of approximately 150mm and produces a stable output size of about 50mm, with low fines and a high lump coal yield – fully meeting the mine’s quality requirements for finished lump coal. The processing capacity reaches 60‑100 tons per hour, with reliable and stable operation.
The greatest value of the mobile design lies in its flexibility. The unit can be relocated quickly as the coal face advances, eliminating the need for raw coal haulage and significantly reducing transport and labor costs. Furthermore, the intelligent, integrated modular design delivers a compact footprint, saving valuable workspace. For applications such as coal mining that require frequent site moves, this advantage is particularly compelling.
With its outstanding features – flexible mobility, no foundation required, fully integrated design, and high-efficiency crushing – the Huashengming mobile double-tooth roll crusher has become the ideal choice for material crushing in coal mining, aggregate production, construction waste recycling, and more. No matter where your site is, the Huashengming mobile double-tooth roll crusher can follow your project – saving you time, effort, and money.
