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.
Applications: сoal, foil, polyester resin, glass, slag, salt, shale, electrical circuits, HHD disks, food products.
Industries: mining, metallurgical, construction, chemical, pharmaceutical.
