This roller crusher utilizes low-speed double-roll compression to efficiently produce sand from medium-hard materials. It offers electricity consumption per ton that is over 30% lower than impact-type equipment, features controllable stone powder content, and allows for adjustable roll gaps.

A complete guide to selecting sand-making equipment: Detailed insights into the working principles, key specifications, and real-world case studies of VSI sand makers. Covering applications for river pebbles, granite, and construction waste, and including analyses of wear costs and return on investment (ROI), this guide helps you configure a manufactured sand production line in a one-stop solution.

The roller crusher (double-roll crusher) utilizes low-speed dual-roll compression to achieve fixed-size crushing. It offers an adjustable output size of 2–30 mm, maintains a fines generation rate of less than 10%, and resists clogging even with wet or sticky materials. It is widely used for the secondary fine crushing of medium-hard, brittle materials such as limestone, dolomite, river pebbles (for sand making), gypsum, and coke.

Compression crushing keeps over-crushing below 10%, handles 10–15% moisture without clogging, output adjustable 2–40mm, 5–120 tph.

This article provides a detailed analysis of the working principle of roll crushers, different types such as twin roll and four roll crushers, and their core advantages. It offers a comprehensive guide to roll crusher selection, application areas, and maintenance points, helping you efficiently solve medium and fine crushing problems.

Coal Crushing with Roll Crushers: Features include an over-grinding rate of less than 10%, clog-free operation with 15% moisture content, and an adjustable output size of 2–35 mm. This guide covers working principles, application scenarios, parameter tables and selection criteria for 2PG/2PGC models, and includes typical configuration examples for power plants and coking plants.

With a Mohs hardness of 6–7, granite is a raw material notorious for causing heavy wear on sand-making equipment. This article analyzes the working principle, sand yield, and particle shape performance of double-roll crushers used for granite, as well as the specifications and typical operating conditions of the 2PG series. It uses data to demonstrate why double-roll crushers are a superior choice for reducing costs and increasing efficiency in hard rock sand making.

A roll crusher crushes coal, coke, slag and clay with under 10% fines, handles 10–15% moisture and delivers adjustable 2–50mm output at 5–160 t/h. Specs and models inside.
