PRODUCT DESCRIPTION

HAZEMAG’s HUM and HNM Hammermills are employed for the fine crushing and/or drying & grinding of medium-hard to soft materials such as: Anhydrite, quicklime, lignite, dolomite, electronic scrap, gypsum, glass, potash, limestone, china-clay, diatomite, chalk, phosphates, salts, French chalk and clay.

Due to their high level of flexibility, Hammermills can be adapted to different operating conditions.

In accordance with machinery directive 2006/42/EC, HAZEMAG Hammermills are equipped with an interlock system, which must be integrated into the plant control.

 

Housing

Hinged sections of the housing are opened hydraulically, and the interior is lined with replaceable abrasion wear plates. Built-in components, such as impact bars, spacer bars (grinding path) and various grates are easily replaceable, and can be employed in various ways to achieve the targeted granular size.

 

Rotor(s)

The HAZEMAG HUM Hammermill is equipped with one reversible rotor.

The HAZEMAG HNM Hammermill is equipped with two non-reversible rotors.

The heavy-duty rotor employed in HAZEMAG’s Hammermills is of a steel disc design, with free swinging (360°) hammers mounted between the discs.

  • The rotor is shaft mounted and fitted with self-aligning roller bearings.
  • The rotor bearings are equipped with temperature sensors.
  • The rotor is monitored for rotor standstill.
  • The new hammer design is manufactured from an improved composite-casting.
  • The innovative shape increases the wear mass by an additional 10%.

 

Electro-Hydraulic Unit

The Hammermill control panel is equipped with the necessary switches, pushbuttons and indicator lamps for operation, and control units for the sensors are also built in. All corresponding signals (on both sides) are available as potential-free contacts for connection to the client’s control system.

The Hammermill’s Electro-Hydraulic Unit is fully installed in a steel frame.

Comprising:

  • Hydraulic power unit with pump and IEC-norm motor (1.1 kW) and top mounted switch cabinet
  • Oil tank, filling & venting filter, temperature & level monitor, pressure control valve, directional control valves in accordance with CETOP 03 standard
  • Handheld remote panel
  • Main bearing temperature monitoring (2xPTC/PT100)
  • Rotor standstill monitoring

V-Belt Drive

The Hammermill’s V-Belt Drive consists of:

  • V-belt pulley for motor
  • V-belt pulley for rotor
  • Set of high-performance V-belts

 

Base Frame with Anti-Vibration Pads (optional)

For the complete crusher assembly.

The base frame allows for workshop assembly and transportation of the complete unit, which reduces on-site installation time. It is installed on anti-vibration pads to minimise vibrations through the support structure / housing. The base frame requires filling with plasticised concrete.

In the mill-drying process, the material is not only crushed, but also dried at the same time. Process gas is passed through the mill in direct flow with the material being crushed. The dried material is generally discharged from the Hammermill via grates, and subsequently via a discharge screw conveyor with rotary valve – which also serves as an air seal.

Fineness of the product is influenced by controlling material flow.

  • With central material discharge, the double-rotor HNM Hammermill achieves maximum throughput capacity since the grinding grate or screen surfaces will offer maximum processing area.
  • With a grinding path installed below the first rotor, material is directed towards the second rotor, and is ground in a two-stage process to achieve a greater degree of fineness.
  • As an option, the product can be pneumatically discharged upwards.
  • The HUM Hammermill is equipped with just one rotor but, because of of the symmetrical structure of the mill housing, the rotational direction of the rotor can be reversed.
  • Unirotor
  • Novorotor
