Hammer mills

Hammer mills are designed to crush brittle materials and break down conglomerates.

The Hammer mill HM 2х2 is laboratory-class equipment designed to crush small batches of material with output up to 100 kg/hour.

Hammer mills HM 5х2 and HM 5х5 are industrial-class equipment used in busy laboratories or in small and medium-sized production facilities.

The operational principle of a hammer mill is based on impact on material particles.

Material particles are broken down:

  • when a hammer falls on them;
  • when they impact the liner and walls of the housing;
  • when the particles collide with each other.

Advantages of VIBROTECHNIK Hammer mills:

  • The ability to obtain various crushed product grain sizes by:
    • installing grates with openings of various shapes and sizes from 0.8 mm;
    • selecting the number and shape of the hammers;
    • changing the HM 2х2 rotor rpm;
    • installing a smooth or ribbed liner in the cover of the HM 2х2;
  • Free suspension of the hammers on the rotor axes reduces the probability of mill breakage when an unbreakable object falls into the working chamber;
  • The size and configuration of the loading funnel have been selected for safe maintenance and to prevent ejection of material particles during operation;
  • The hinged bolts on the cover of the HM 2х2 provide quick access to the crushing chamber for inspection and replacement of hammers and grates, and cleaning
    of the chamber;
  • Ability to connect to the dust collector to:
    • lower the temperature in the crushing chamber;
    • lower the content of the dust fraction in the product;
    • separate material into three fractions: sedimented into the crusher receiving container, cyclone and bag filter.
  • Equipment of the HM 5х2 and HM 5х5 with a support frame and receiving containers of various volumes depending on the process task.
