APPLICABILITIES
Widely used for fine crushing and forming of various ores, this device is especially suitable for secondary and fine crushing of several types of hard and brittle materials with a water content not exceeding 20%, including abrasive materials, quartz sand, limestone, cobblestone, granite, concrete aggregate, refractory materials, bauxite clinker, metallurgy slag and abrasive wear resistant materials.
WORKING PRINCIPLE
The 8HL series high-efficiency impact crusher with waterfall flow feeding system, which introduces the second material flow into the crushing chamber with a certain controlled amount to increase the quantity or density of the material in the crushing chamber, which promotes the energy exchange between the particles.
The materials entering the crushing chamber violently collide with suspended materials and material gaskets. They collide with the materials emitted from the spinning wheels again. After repeated collision, friction, grinding and crushing, the materials are discharged through the lower discharge port.
FEATURES
l HYDRAULIC UNCOVERING DEVICE
These crushers are designed with a simplified structure, making them easy to operate and install. Furthermore, the hydraulic uncovering device enhances convenience during overhauls and reduces stop time.
l HIGH PRODUCTION EFFICIENCY
Switching between "stone hitting iron" and "stone hitting iron" models increases production efficiency, creates better granular shapes of products and reduces needle-shaped particles.
l PRODUCT GRADATION CONTROL
Product gradation can be controlled by adjusting mode of crushing chamber or size of waterfall flow.
l EXTEND CYCLE OF SPARE PARTS
With combinational design of peripheral guard, locally worn parts can be further used after turning up and down. Hence, the combinational design prolongs replacement cycle of spare parts.
l PROLONG SERVICE LIFE OF TRIANGLE
Hydraulic tensioning device effectively promotes triangle tensioning of large 8HL impact crushers, increases friction, controls triangle vibration, and prolongs service life of the triangle.
l HIGHER RECOVERYRATE OF MINERALS
Extraordinary monomer dissociation increases recovery rate of minerals.
l OPTIONS
With multiple models available, these crushers are idea choices for sand production by fine crushing.

The production capacity shown in this form varies with operation parameters of XHL series (RPM, spillover ratio, and variables on physical characteristics of materials). It is specific to materials with a bulk density of 1.6t/m3 which are smoothly fed and discharged.
The calculations for central feed in the above form are as follows: lower limit = linear rotor speed (75m/s) (0% waterfall flow) upper limit=linear rotor speed (60m/s) (0% waterfall flow)
The calculations for central feed in the above form are as follows: lower limit = linear rotor speed (75m/s) (30% waterfall flow) upper limit =linear rotor speed 75m/s)(100% waterfall flow)
