Quick Details

This Impact Crusher For Sale is ideally suited to crush medium-hard, non-abrasive materials down to a cubical, well-graded product size of 0-5 mm (60% passing) in a single pass. Due to its added control over the upper product sizes and high reduction ratios, it can efficiently operate in closed circuits on smaller product fractions.

Working Principle

Primary Impact Crusher is a kind of crushing machine that uses the plate hammer of the high-speed rotating rotor to crush the materials at a high impacting crushing force. When the materials get into the action area of the plate hammer, they are crushed by the hammer at a high speed. The crushed materials are thrown to the impact plate along the tangential direction to crush again. Then they are rebounded from the first impact plate to the action area of the plate hammer and enter into the second impact plate to repeat the above process. During this process, materials also crash with each other. This process will proceed repeatedly until the material is crushed to the required granularity and then discharged from the clearance between the impact plate and plate hammer.

Parameters

Features of Primary Impact Crusher

1. The special design of heavy rotor structure provides extremely high rotary inertia and impact crushing force for hammerhead to improve the first-time crushing pass rate.

2. The special design of the hammerhead makes its crushing profile remain unchanged during the service life to ensure the stability of the product gradation.

3. The spare parts adopt modular design, which ensures high interchangeability, easy control and low cost.

4. The rear frame and access door can be opened at same time to replace all the wearing parts, which improves the work efficiency greatly.

Application

Primary Impact Crusher is used in water conservancy and hydropower, construction, highway and high-speed railway, etc.
Applied Material: aggregates with compressive strength >300MPa, Moh’s hardness > level 6.
