Size reduction is a common feature of the chemical, pharmaceutical, food, energy, mineral and other industries; from waste char handling to preparing raw sugar for processing through to meeting stringent quality needs for active pharmaceutical ingredients. Ajax lump breakers are ideal for reducing lumps, caked and bag set materials to a suitable consistent size for ease of processing and handling.
Multiple mechanisms are used by the Ajax lump breaker to reduce the lump size. The shafts and blades impose a three-stage action on the lumps, wedging and crushing against the casing and grille by means of the orientation of the blades and the shafts. Final size limitation is imposed as lumps are combed or forced through the grille by means of the blade edge.
The actual size of particles exiting the lump breaker is determined in part by the clearance between rotor and grille but is also very much dependent on the characteristics of the material lumps such as brittleness in the case of crystalline material and consolidation strength in the case of agglomerations also, highly anisotropic materials will have a tendency to form shards. Machine speed also influences both the average particle size and the particle size distribution of material exiting the lump breaker.
Features of AJAX lump breakers include:
Dynamic impact, crushing and combing action through a grille
LynFlowTM rotor design for effective size reduction
Controlled lump breaking without causing excessive dust and fines
Range of sizes and grille spacing to suit operational needs
Single and twin shaft units in stainless and hard wearing steels
ATEX, food and pharma quality versions
Easy to operate and maintain
Hopper, chute and sack tip versions
The list of materials with which our lump breakers have been used is quite diverse. The following are some examples of materials and products that are currently processed with our breakers:
Mixed residue from the nuclear industry
Dried Aloe Vera
Mixed frozen food
Unspecified Active Pharmaceutical Ingredients
Caked Detergent Powder
Carbon Fibre Blocks
Whilst not always possible, it is advisable to undertake pilot machine trials to determine the best design and configuration of rotor blades and grille for each specific application. AJAX have a range of Lump Breakers for pilot machine trials at our Bolton manufacturing plant or for on-site trials.

The ISO 9001 ‘quality’ standard is one of the most commonly used management system tools across the world. This standard uses a process approach and is based on quality management principles, with a strong customer focus, active involvement of top management, and is satisfied by continually monitoring and managing quality across all operations so as to check for consistent performance and drive towards improvement.
