DP Single-Cylinder Hydraulic Cone Crusher

Feed Size:: ≤ 350 mm

Capacity:: 40-800 T/H

Applicable Materials:: Pebbles, basalt, granite, iron ore, iron ore, copper ore, quartz, granite, basalt, diabase

Application Range:: From limestone to basalt, from aggregate production to the crushing of various ores, efficiently accomplishing all medium crushing, fine crushing, and ultra-fine crushing operations.

The crushing of medium-to-high hardness metal ores remains the most traditional primary application for single-cylinder cone crushers. Leveraging their superior particle shape control capabilities and high production efficiency, these crushers are increasingly employed in the production of high-quality construction aggregates (sand and gravel).

Description

Product Overview

The single-cylinder cone crusher is a medium-fine crushing device employing modern hydraulic technology, occupying a significant position in the crushing field due to its compact structure and intelligent operation. This equipment achieves integrated control of discharge opening adjustment, iron overload protection, and cavity cleaning through its bottom-mounted single-cylinder hydraulic structure, simplifying the complexity of traditional multi-cylinder designs. Its unique fixed-shaft design enables the moving cone to operate with greater swing amplitude and higher rotational speed. Combined with the principle of laminar crushing, this subjects materials to multiple squeezing and impact forces within the crushing chamber. Consequently, it effectively processes medium-to-high hardness materials while producing uniform particle shapes and high cubic content. The intelligent control system continuously monitors operational status and automatically optimises working parameters, significantly reducing energy consumption while maintaining crushing efficiency. With its intelligent operation, straightforward structure, and convenient maintenance, the single-cylinder cone crusher stands as a vital crushing solution for modern mining operations and aggregate projects.

Working Principle

The primary components comprise the upper frame, middle frame, lower frame, moving cone assembly, eccentric sleeve assembly, transmission assembly, and hydraulic cylinder assembly. An electric motor drives the horizontal shaft to rotate; this shaft, through helical bevel gear meshing, drives the eccentric sleeve to rotate. The eccentric sleeve then drives the moving cone assembly to perform a rotational swing motion, thereby achieving continuous compression crushing. The DG Series Single-Cylinder Hydraulic Cone Crusher adjusts the clearance between the moving cone liner and fixed cone liner by actuating the hydraulic cylinder at the base of the moving cone. This cylinder drives the main shaft, causing the moving cone assembly to move vertically and thereby controlling the final product size. Concurrently, the hydraulic cylinder incorporates overload protection: should non-crushable foreign objects (such as iron blocks) enter the crushing chamber, the accumulator activates, causing the hydraulic cylinder to automatically lower the movable cone. This releases the foreign object, enabling the crusher to resume operation and safeguarding the equipment.

Features

Streamlined structure, high reliability

Featuring an integrated spindle and moving cone design, this model eliminates the complex shaft adjustment mechanisms and spherical bearings found in traditional multi-cylinder cone crushers. This significantly simplifies the mechanical structure, resulting in more stable and reliable operation with markedly reduced failure rates.

Intelligent hydraulic control for effortless operation

The single-cylinder hydraulic system integrates four key functions: support, adjustment, locking, and over-iron protection. The hydraulic system facilitates straightforward discharge opening adjustment and cavity clearing operations, with remote control capability significantly reducing labour intensity.

Laminar crushing with superior particle shape

The optimised crushing chamber design, combined with the principle of laminar crushing, subjects the material to multiple squeezing and grinding actions within the chamber. The resulting product exhibits a cubic particle shape with low content of elongated and flaky particles, fully meeting the requirements for high-standard aggregates.

Maintenance is straightforward and operation is economical.

The simplified structure significantly reduces maintenance workload. The hydraulic cavity-clearing function enables rapid production resumption in the event of blockages, minimising downtime. Wear parts boast extended service life, delivering a distinct advantage in overall operating costs.
