Overview
The JOYAL VSI Crusher, developed by Shanghai Joyal Mining Machinery Co., Ltd., is an advanced sand making machine based on German technology. It is designed for high efficiency and superior performance, widely used in producing sand and stone for infrastructure projects such as highways, railways, and hydropower dams.

Key Features

• Dual oil pump system ensures automatic shutdown if oil is absent, with automatic motor heating in winter.
• SKF and TIMKEN bearings for reliable operation.
• Hydraulic lifting system for easy maintenance and spare parts replacement.
• Vibrating alarm device for abnormal operation detection.
• Dustproof seal system to protect spare parts.
• Innovative material bumping angle design reduces friction and extends spare parts' lifespan.
• Special feeding structure for effective stone crushing and reshaping.

Working Principle

• Center Feeding: Materials enter through a central inlet, accelerated by a high-speed impellor, and crushed upon impact with a plate.
• Ring Feeding: Materials are divided, with some entering the impellor and others falling outside, leading to multiple crushing stages.
