The toothed roll crusher is a high-efficiency and energy-saving mining crushing equipment. This article details its working principle, core advantages such as low-over-crushing, good particle shape, and simple maintenance, as well as its applications in the mining, building materials, and coal industries.

Toothed roll crushers utilize a shearing and splitting mechanism to crush coal, offering a fines generation rate of less than 10%, clog-free operation even with moisture content exceeding 15%, and adjustable output granularity. This overview details the specifications of the 2PGC series, application scenarios (power plants, coking plants, and coal preparation plants), and real-world case studies, along with key selection criteria.

We provide a professional explanation of the working principle, materials processed, core advantages, and selection considerations of toothed double-roll crushers. Includes real-world case studies and FAQs to help you efficiently solve the problem of coarse crushing of medium-hard materials.

Toothed roll crushers are specifically designed to solve the problems of high water content and high mud content in weathered rock—shearing and extrusion crushing, no material blockage, low over-grinding rate, and one-step crushing. This article details the parameters, application scenarios, and supporting solutions for the 2PGC series. Baichy Heavy Industry supports free material testing and selection quotation.

There is more than one type of toothed roll for double-roll crushers: they are categorized by roll count (single vs. double), tooth profile (spike/wolf-tooth, square, and fine teeth), and manufacturing process (integral casting vs. segmented tooth rings). This article details the differences between roll types, suitable materials, and selection logic. It also includes a parameter table for the 2PGC series and case studies on model retrofitting to help you make the right choice the first time and avoid costly mistakes.

Steel slag is characterized by high hardness, a metallic iron content, and strong abrasiveness; the primary challenges in its crushing lie in the separation of slag from iron and the wear of the roll surfaces. Utilizing low-speed compression and shearing to achieve dissociation at the slag-iron interface, offering uniform and controllable discharge, and featuring an automatic hydraulic retraction mechanism upon encountering iron, the double-roll crusher serves as a key piece of equipment in the fine crushing stage of steel slag processing.

The smooth roll crusher utilizes compression crushing between two smooth rolls, with the output particle size precisely controlled by the roll gap. It ensures uniform particle size and minimal fines generation, making it widely applicable for the fine and final crushing of materials such as coal, coke, clinker, limestone, glass, and ceramic raw materials. It offers a processing capacity of 2–150 t/h and is equipped with scrapers to prevent clogging when handling wet or sticky materials.

The smooth double-roll crusher utilizes two smooth rolls rotating towards each other at low speeds to crush material through compression. The output particle size is precisely controlled by the roll gap, resulting in uniform sizing and minimal fines generation. It is widely used for the fine and final crushing of manufactured sand, coke, cement clinker, and raw materials for glass and ceramics. With a production capacity ranging from 2 to 150 t/h, the machine prevents clogging when handling wet or sticky materials through the use of scrapers, and the roll shells can be repaired via hard-facing welding.
