Introduction to Common Types of Crushers Used in Quarries
Crushers are core equipment to process large rocks into qualified sand and gravel aggregates in global quarry production. Different types of crushers meet diverse demands in material hardness, finished particle size and production capacity. With 15 years of experience in crushing and screening industry, Shanghai Dongmeng develops a full range of quarry crushers including jaw crusher, impact crusher, cone crusher and mobile crusher. Featuring high efficiency, wear resistance and environmental friendliness, our equipment is suitable for granite, basalt, limestone and other ores, helping global quarries realize high-output, low-cost and eco-friendly production.
Jaw Crusher: Core Primary Crushing Equipment for Quarries
Main Features
It adopts extrusion crushing principle with deep and large feeding opening, capable of handling raw rocks over 1000mm.
It has simple firm structure, low failure rate and easy maintenance with economical operating cost. It achieves large crushing ratio and uniform output size.
Application Scope
Ideal for primary crushing of all kinds of hard ores such as granite, basalt and river pebble.
It serves as the first-stage equipment in large quarry production lines, compatible with stationary and mobile crushing systems.
Dongmeng Advantages
Optimized European-style crushing cavity, high manganese steel wear-resistant jaw plates and hydraulic discharge opening adjustment realize quick parameter adjustment within 10 minutes.
Impact Crusher: First Choice for Secondary Crushing and Aggregate Shaping
Main Features
Adopting impact crushing principle, it produces cubic and well-graded finished materials with perfect particle shape.
It features high working efficiency, adjustable discharge size and low energy consumption, perfectly suitable for medium and soft materials.
Application Scope
Widely used for secondary crushing of limestone, sandstone and construction waste.
Perfect for producing high-grade aggregates for highway, municipal road and building projects.
Dongmeng Advantages
Equipped with heavy-duty rotor and large-capacity crushing cavity, its hourly output reaches 80-360 tons. Fully enclosed dust reduction design fully meets global environmental protection standards.
Cone Crusher: Main Equipment for Hard Rock Secondary Crushing
Main Features
Based on laminated crushing principle, it delivers even crushing force specially designed for high-hardness stones.
Key wear parts are made of high manganese steel and high chromium alloy for long service life and low maintenance cost.
It maintains stable output and excellent finished shape with high automation level.
Application Scope
Suitable for secondary and fine crushing of granite, basalt, diabase and other high-hardness ores.
Matched with jaw crusher to form high-capacity production lines in large-scale quarries.
Dongmeng Advantages
Hydraulic driving and automatic control system are equipped with overload protection and liner wear compensation device. Thin oil lubrication system effectively extends equipment service life.
Mobile Crusher: All-Rounder for Flexible Quarry Operation
Main Features
Integrated crushing, screening and conveying structure with crawler or wheeled chassis enables free field transfer.
No fixed foundation installation is required, and it can be put into operation rapidly adapting to mountainous and complex terrain.
Dual power supply mode ensures stable operation in remote areas without stable power supply.
Application Scope
Perfect for scattered ore veins, mountain quarries and temporary mining projects.
Ideal for old quarry renovation, waste recycling and multi-site alternating operation.
Dongmeng Advantages
Lightweight optimized design achieves larger crushing ratio. Pre-screening function reduces invalid crushing volume, which has been verified by practical projects in more than 120 countries worldwide.
Vertical Shaft Impact Crusher (Sand Making Machine): Equipment for High-Quality Manufactured Sand
Main Features
It realizes crushing and shaping functions via high-speed impact and rock-on-rock crushing principle.
Finished sand has reasonable gradation and adjustable fineness modulus with smooth particle shape.
It is energy-saving, efficient and low in wear to meet high-standard sand production demands.
Application Scope
Make full use of quarry tailings and leftover materials to maximize resource utilization rate.
Produce high-quality manufactured sand to replace natural sand for construction and road engineering.
Dongmeng Advantages
Optimized rotor structure increases production capacity by 30%. All finished products are cubic-shaped and fully conform to international aggregate standards.
