The 911MPEPYB600 is a small (24") diameter cone crusher is perfect for fine, secondary crushing in small operations. Ideal to re-crush rock discharging from a primary jaw crusher. Feed this short head cone crusher up to 35 mm (1.5") with a CSS closed side setting 3mm (1/8") to obtain a P80 crushed product in the 3 to 13mm (1/8" to 1/2") range. When crushing fine, the crusher's capacity is reduced to 5 to 20 TPH - The finer, the slower. A manganese-chrome mantle and concave, greased seal, lube system with temperature control. Chrome-moly main shaft and heavy steel casting main structure.
For finer crushing or reduction a Symons cone crusher the the norm. Symons are commonly used for secondary, tertiary or quaternary crushing. They do this by a different chamber design which is flatter and by operating at about twice the rotational speed of a primary-type gyratory crusher. One of the first cone crushers had a direct drive vertical motor mounted above the spider with the drive shaft passing through the hollow bored main shaft. With relatively high speeds of 480 to 580 rpm and small eccentric throw the machine produced a uniform produce with minimum fines. There are numerous Symons cone crusher manufacturers of modern crushers each promoting some unique aspect. The Allis Chalmers Hydrocone' selling point is its adjustability and tramp protection through a hydraulic support system for the headcentre. By merely adjusting the oil reservoir below the head centre the crusher setting can be changed while in full operation. Tramp metal causes a surge of pressure in this hydraulic system which is absorbed through relief valves and gas-bladder filled accumulator bottles which allow the headcentre to momentarily drop and return to its normal operating position when the tramp has fallen through. The Symons or Rexnord spring cone crusher is adjusted by spinning the bowl up or down manually or through hydraulic rams. A series of powerful springs give the necessary tramp protection. Several other manufacturers produce similar types and sizes of crushers but all follow the basic types described.
The 911MPE-TM-LCC21 Laboratory Cone Crusher grinds 19 mm feed to -10 mesh and grinding fineness can be precisely calibrated by easily rotating the adjusting ring. Custom cones are available in materials to suit specific applications. The Laboratory Cone Crusher is typically used in applications where there are space limitations or flat (plate-like) rocks are being crushed. It weighs 273 kilos and comes with a 3 phase 60 cycle 3 HP motor as standard. A 1 phase and / or 50 cycle motor is available which must be specified at time of ordering. It has rugged, fabricated cast steel construction with reinforced joints and internal welds and joints ground and polished. The funnel can be easily removed by simply rotating and lifting up.
