Kek-Gardner offer a wide range of different types of size reduction mills extending from coarse De-lumping / Pre-breaker units, through to ultra-fine Air Classifier Mills
The Kek-Gardner Lump-Breaker mill is a heavy duty mill for coarse grinding and lump breaking applications.
The Lump Breaker can be supplied with conventional shaft support at both ends for heavy duty applications but for less arduous processes, it can be supplied with cantilever shaft mounting for improved access and cleanability.
The Lump Breakers can accept lumps up to 150mm dia., and reduce them to less than 2-3mm and are used for a variety ofprocesses such as:-
De-agglomeration - Breaking down of compacted hygroscopic products that have agglomeration due to dampness or compaction.
Pre-milling - Pre-grind of very large lumps to a particle size small enough for further grinding. Coarse Grinding - Product is broken down for use (e.g. melting or dissolving) in another process.
Cone Mills are designed for intermediate granulation and de-agglomeration applications, with a gentle, low energy form of size reduction. Used for a wide range of applications including size reduction of fatty, heat sensitive, sticky, moist or fragile products. Cone Mills avoid traditional milling problems of noise, dust and heat generation.
The gentle grinding action of Kek-Gardner Cone Mills, capable of control within fine limits, maintains a close particle size distribution with minimal fines generation, grinding tp typically 250 - 300 micron particle size. Fine grinding Universal Mills are designed and constructed for aggressive, one pass milling.
A range of models are available to suit a variety of process and throughput requirements from a few kgs to several tons per hour.
Typical requirements are to grind materials of up to 3 Moh hardness down to less than 15μm particle size.
Universal Mills can be fitted with either Turbine & Screen, Pinned Disc or Ribbed Track grinding media.
The Kek-Gardner Air Classifier Mill offerseven finer grinding capability, plus greater control over particle size distribution.
Typically grinding to a particle size in the region of tens of microns, the Air Classifier Mill serves all industries producing fine powders where control ofgrinding temperature and particle size distribution is of prime importance.
Particle size is controlled by fully adjustable rotor speed,classifier speed, airflow rate and feed rate.
Many materials that are milled have the potential to ignite during the milling process, and this must be accommodated in the mill design. As well as traditional vented systems, Kek-Gardner specialise in nitrogen inerted and 10 bar PSR milling systems.
