Vertical Shaft Impactors have the unique feature of adjustable operating speed. These machines perform by applying velocity to the incoming mineral. Typically, crushing velocities below 250 fps (75 mps) are crushing speeds that can be applied to feed sizes from 4" (100 mm) to approximately 1/2" (13 mm). When the feed size is smaller than this, it has a low mass value. In order to reduce it, greater than normal velocity must be applied. When the speed exceeds 250 fps (75 mps) the result is high inter-particle compression and forceful attrition which achieves a milling effect. REMco Vertical Shaft Grinder - VSG units operate well above crushing speeds and mill with velocities up to 360 fps (110 mps).
Hence all REMco units that operate at the highest velocities are referred to as grinders or VSG. When this speed is combined with REMco’s unique chamber, rotor geometry, and special lubrication, their VSGs make products that were once only possible with a rod mill or ball mill. Their VSGs can make products as fine as 100% minus 65 mesh and since final product size is heavily influenced by mineral characteristics, REMco takes the time to understand your unique product needs by performing a crushing or grinding test. This helps establish how fine a product can be made with your given rock, or mineral, and how your VSG should be configured.
GlassMax
Do you need to grind some glass? The GlassMax easily converts all forms of glass cullet (with or without contaminants) to fine, furnace-ready powder.
GlassMax
REMco GlassMax Vertical Shaft Grinders were originally developed in 1991 and have since become a worldwide standard for crushing and grinding glass. Different from REMco’s Vertical Shaft Impactors (VSIs), the Vertical Shaft Grinder (VSG) uses much higher speeds. VSGs are typically used to produce a wide variety of fine industrial mineral products such as in refractory mining, recycling, silica production, fuse alumina grind or other severe tasks. GlassMax is specially designed for pulverizing waste glass containers, plate glass, and other types down to a fine cullet.
Like all other REMco machines, GlassMax is incredibly versatile and can be also be configured to make more coarse products like glass chips and grit. Highly efficient, the GlassMax is available in sizes from model 50 to 300 which can produce minus 12, 16, and 20 mesh, or even finer, contaminant-free cullet powder.
REMco takes the time to help you design your cullet grinding circuit to ensure all GlassMax models neutralize or reject all common contaminates like ceramics, ovenware, ferrous and non-ferrous metals, and plastics so your machine produces only a finely-ground, furnace-ready, beautiful powder. The REMco GlassMax is the only machine that reduces cullet and produces a contaminant-free powder that can be fed directly to the furnace. It’s all made possible because of REMco’s innovative and exclusive use of non-metallic linings and construction of the cullet flow path with the grinder.
REMco’s GlassMax uses a refined and field-proven glass-on-glass differential grinding which also prevents powder contamination by metal particles caused by machine wear parts. Their production capabilities range from handling materials with feed sizes of 1 1/2″ (40 mm) and smaller. They produce materials as small as 65 mesh (0.212 microns) typically in a closed circuit with a mechanical sizer or air separator. REMco will work with you closely to design your circuit to maximize production.

VSG
Need a powerful machine to help with all your grinding? These machines are more accurately defined as high-speed grinders, hence the designation ‘G’ to set them apart from the normal VSI design.

VSG
REMco produces a special series of crushers called VSG. These machines are more accurately defined as high-speed grinders, hence the designation ‘G’ to set them apart from the normal VSI design.
This series is typically applied for the production of a wide variety of fine industrial mineral products. For example, these machines operate in the refractory industry, recycling industry, and in silica production, fused alumina grinding and other severe tasks.
The VSG units are available in sizes that use drive powers from 30-350 hp and are full autogenous with chambers specially designed for the unique needs of industrial minerals and man-made products. Their production range is in handling materials from feed sizes of 1 1/2” (40 mm) and smaller, and to producing materials as small as 65 mesh (0.212 microns). Their typical mode of operation is in closed circuit with a mechanical sizer or air separator.
VS/4G
Ready to produce the lowest costing roofing granules out there? The VS/4G was designed to meet this increased production requirement while lowering crushing costs.

VS/4G
Producing roofing granules has presented a severe challenge to crusher manufactures for decades. The old traditions of using cone crushers and role crushers is increasingly expensive because of their low productivity. Production demand for roofing granules rises each year as housing demand grows globally.
To meet this increased production requirement while lowering crushing costs, REMco developed an extra heavy duty (XHD) design of VSI crusher called VS/4G. As quarried stone for the production of granules is always very hard, vertical shaft machines must operate at very high velocity and often for a 24/7 cycle. This requires a super strong crusher which only REMco builds to meet this duty.
Depending on the desired granule grading, anywhere from 8-12 hp per net finished ton of granules are required. REMco’s VS/4G replaces roll and cone crushers in existing plants with minimum retrofit time and cost. It also improves granule yield by minimizing the production of undesirable fines and the granule shape is superior to what compression machines create.
