Product Introduction
The PXJ fine crusher is a new, versatile fine crusher that combines fine crushing and sand making. It is widely used in the sand and gravel crushing and ore crushing industries.
This fine crusher can partially replace the functions of a sand maker and is suitable for materials with moderate abrasiveness, such as those with a compressive strength of no more than 150 Mpa and a surface moisture content of no more than 10%.
The fine crusher can reduce the average particle size of materials to ≤5 mm and is widely used in cement plants for fine crushing, sand and gravel aggregate crushing, and manufactured sand production.
Working Principle
The PXJ fine crusher is a high-speed, high-frequency impact crusher. Material is fed into the top and falls onto a high-speed rotating rotor. This rotor is armed with multiple rows of high-strength, wear-resistant hammer heads (blow bars).
The hammers strike the material with extreme velocity, shattering it on impact. The material is then thrown against specialized impact liners (anvil plates) inside the crushing chamber for further reduction. This process of high-speed impact and grinding is repeated until the particles are fine enough to be discharged, resulting in an exceptionally fine, cubical product.
Overview of Advantages
- 50% Energy Savings:
The PXJ fine crusher is an energy-saving machine, saving 50% more energy than traditional fine crushers, making it one of the most mature and cost-effective fine crushers in the industry. - Excellent Fine Crushing (≤5mm Output):
It is designed to produce an exceptionally fine final product, with an average particle size that can be reduced to ≤5 mm. - Versatile Dual-Purpose Machine:
This single machine effectively combines fine crushing and sand making, and can partially replace the functions of a more expensive sand maker (like a VSI) in many production lines. - Handles Difficult Materials:
The unique design is suitable for materials with moderate abrasiveness and can effectively process materials with a surface moisture content of up to 10% without clogging. - Durable with Low Wear:
The crushing action is optimized for low abrasion, leading to a long service life for wear parts and reduced maintenance costs.
