GPS Series Primary-Secondary Impact Crusher

The GPS is a General Makina HSI crusher that combines primary and secondary impact crushing in a single body. It accepts large feed and, from one machine, delivers both coarse crushing and cubical secondary product, reducing plant stages and investment cost. It is optimised for limestone and low-to-medium abrasive lines.

Technical data

Working principle

A wide rotor with a staged apron layout: coarse feed is broken by impact and, in the same cavity with a close apron setting, reduced to cubical size. A two-stage-in-one-machine approach. Stage: combined primary+secondary.

Material and application

Suitable: limestone, dolomite, soft-to-medium non-abrasive rock and C&D recycling. Not suitable: high-silica granite/basalt/gravel (impact + high abrasion = fast part wear). The combined design cuts CAPEX in limestone ready-mix/asphalt aggregate production.

Reduction and wear (TCO)

Combined reduction follows primary HSI (up to 20:1 on limestone) plus secondary (~10:1) logic and is high; the net combined ratio is project-specific and confirmed with field data. Wear parts are blow bars and aprons: high-chrome on clean limestone, manganese/martensitic in recycling. One machine = one wear set + one chassis/motor → less downtime and lower installation and TCO than two separate machines.

The GPS is the core machine of a complete plant covering crushing, screening, washing and concrete batching, supplied from a single source.
