DLKZS Series Reversible Hammer Crushers

DLKZS Series Reversible Hammer Crushers

DLKZS series reversible hammer crushers are used for sand making.

A reversible hammer crusher is a single-rotor hammer crusher with a rotor that can rotate in both directions. Zhongyu Dingli combines the performance advantages of reversible hammer crushers and dual-rotor sand making machines, and, based on market and customer needs, continuously innovates and improves its products in terms of stability, ease of maintenance, and intelligent operation, developing the DLKZS series reversible hammer crusher. This machine can be used for sand and aggregate production, as well as for crushing hard rock materials such as granite and pebbles.

Application Areas: It can be used for sand and aggregate production, as well as for crushing hard rock materials such as granite and pebbles.

Reversible Rotor

No need to flip hammers manually.

  • Symmetrical Chamber – The DLKZS reversible hammer sand maker adopts a symmetrical chamber design.
  • Forward & Reverse Rotation – The rotor can operate clockwise and counterclockwise after a period of operation.
  • Dual-Side Hammer Use – Both sides of the hammer can be used without manual flipping.
  • Uniform Wear – Ensures even wear of liners and grate plates on both sides.
  • Lower Maintenance – Reduces maintenance workload and improves equipment service life.

Deep Bolt

Protects bolts from abrasion damage.

  • Deep Hole Design – The bolt head countersink adopts a deep-hole structure to reduce exposure to materials.
  • High-Strength Bolts – Main liners and side liners are secured with hexagonal high-strength bolts for firm installation.
  • Wear Protection – The deep countersunk design prevents bolt heads from being worn by small crushed materials.
  • Extended Service Life – Improves durability of fastening components and reduces maintenance frequency.

Adjustable Grate

Flexible gaps with easy installation.

  • Selectable Gap Size – Grate bar gaps can be selected according to different discharge size requirements.
  • Precise Size Control – Helps achieve more accurate control of the final particle size.
  • Flat Surface Fit – The grate plate and grate frame adopt a flat-surface connection design.
  • Quick Installation – Makes installation and replacement faster and more convenient.

Hydraulic Adjustment

Easy grate frame positioning and control.

  • Hydraulic Regulation – The grate frame can be adjusted hydraulically up and down according to material size and wear of hammers and grate plates.
  • Labor Saving – Hydraulic adjustment significantly reduces manual effort and maintenance time.
  • Auxiliary Positioning – Equipped with a screw rod and nut combination for precise grate frame positioning.
  • Cylinder Protection – The auxiliary structure prevents excessive force on the hydraulic cylinder, extending its service life.

 Sichuan 250–300 TPH Granite Crushing Production Line

Sichuan 250–300 TPH Granite Crushing Production Line

The picture above shows the production site of a 300 TPH granite crushing production line. Unlike traditional hard rock crushing lines that require multiple crushers, this project uses a single KPC1313 hard rock crusher to complete the crushing process.
Hunan Liuyang Xinlei 250–350 TPH Aggregate and Sand Production Line

Hunan Liuyang Xinlei 250–350 TPH Aggregate and Sand Production Line

The raw materials are first evenly fed into the hammer crusher through a vibrating feeder for primary crushing. After the initial crushing stage, the material is conveyed to the KPC1313 double-chamber hard rock crusher for secondary crushing and shaping.
