Crushing Parts

Crushing activities involved in mining, quarrying or recycling are carried out by impactors which are either Vertical Shaft Impactors (VSI) or Horizontal Shaft Impactors (HSI).

Blowbars The central piece of Horizontal Shaft Impactors is the rotor. It can be fitted with either four lines of x hammers or with four Blowbars positioned in a star. When turning, the rotors will rotate the hammers or the Blowbars at a certain speed in order to break the rocks fed in through the top. An ideal Blowbar has to have two main characteristic, namely, a design that will best break the feed stone and an alloy that will best resist wear and shocks to retain the original shape of the Blowbar.

Impact Plates Impact plates are produced in High Chromium Cast Iron, White Iron, Martensitic Steel and Manganese Steel for application in Gravel Pits and Quarries, in a Horizontal Shaft Impactors unit.

Side Liners Side Liners are produced in White Iron, Low Chrome and Medium Chrome for application in Gravel Pits and Quarries, in a Horizontal Shaft Impactors unit.

Impeller A standard Vertical Shaft Impactors unit uses a rotating Impeller with iron wear shoes and a chamber with Anvils. An ideal Impeller has to maintain an optimum balance between the design and the materials used to achieve best performance, based on the composition of the feed.

Anvils A standard Vertical Shaft Impactors unit uses a rotating impeller with iron wear shoes and a chamber with Anvils. An Anvil type crushing chamber consist of 15 to 20 Chrome iron blocks positioned around the circumference of the machine against the rotor throws the rock to be crushed.

Hammers Hammers are used in the cement industry to crush limestone extracted from the Quarry, for lump size reduction before feeding the kiln. Hammers are of two types, namely, primary and secondary. Crushing upstream of vertical mills and kiln sometimes require a second crushing step, where the conditions are similar to the primary Hammers, only less severe.
