Overview

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: 

  • 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

Coal, foil, polyester resin, glass, slag, salt, automobile catalyst, shale, electrical circuits, HHD disks, food products.
