Product Overview

        Vertical impact crushers have low operating costs, strong adaptability, high throughput, excellent product quality, and wide application, among other unparalleled competitive advantages. Thousands of these products are currently in use across numerous domestic sectors.
        Depending on operating conditions or materials being crushed, PLS series vertical impact crushers utilize either a "stone-on-stone" or "stone-on-iron" crushing mechanism by controlling material entry. The "stone-on-stone" method employs a waterfall material distribution system, splitting the incoming material into two streams in a controllable manner. One stream enters the high-speed rotating impeller's inner cavity via the central inlet pipe, while the other stream falls into the equipment cavity through multiple overflow ports on the circumference of the hopper. The material entering the impeller cavity is accelerated by high-speed rotation and ejected from three or more discharge ports, violently colliding with the material falling from the overflow ports in the impeller's peripheral region, resulting in "stone-on-stone" crushing. The "stone-on-iron" method involves directing all incoming materials from the central inlet pipe into the high-speed rotating impeller's inner cavity. After being accelerated by the high-speed rotation of the impeller, it is ejected from three or more discharge ports and violently impacts the metal impact plate installed on the inner wall of the equipment's crushing chamber, resulting in "stone-on-iron" crushing.

Product Features

1. This equipment can be optionally configured with a manual hydraulic pump to adjust the impeller's material flow rate. In combination with adjustments to the height of the splitter plate, the proportion of material entering the impeller and the material falling from the circumference can be accurately controlled.
2. This equipment can also be optionally equipped with a suspended manual or electric hoist for easy lifting of the top cover, hopper, splitter, impeller, and main shaft during equipment maintenance, making maintenance and repair more convenient and efficient.
3. The equipment's top cover can be optionally equipped with a hydraulic lifting opening device, facilitating the lifting and rotation of the hopper during equipment maintenance for easy removal. This equipment features both "stone-on-stone" and "stone-on-iron" crushing modes, both of which can share the same crushing chamber. A simple component change enables switching between "stone-on-stone" and "stone-on-iron" crushing, allowing it to adapt to a wider range of operating conditions and different material crushing and shaping requirements.

4. The equipment can also be optionally configured with a thin oil lubrication system and a PLC automatic control and monitoring system to monitor the material inflow, current, oil temperature, main shaft temperature, and vibration protection in real-time.

Wide Applications

        Vertical impact crushers are widely used in various metal and non-metal mines, refractory materials, abrasive ceramic raw materials, building materials, high-speed rail construction, water conservancy and hydropower construction, and private sand and gravel production for the fine crushing and shaping of minerals and rocks. They are particularly advantageous for crushing medium-hard, extra-hard, or abrasive materials such as sandstone, granite, basalt, silicon carbide, silicon carbide grit, bauxite, and magnesia sand, offering superior performance compared to other equipment.
Vertical impact crushers can also operate in a high-speed mode exceeding 80 m/s for secondary fine crushing and shaping of coarse sand particles in the sand and gravel processing industry. This optimizes the grading of finished sand particles and can reduce the fineness modulus of the sand.
