MACSALAB Rolls Crusher size '0' and '1' are designed for secondary reduction after jaw crushing. These smooth roll crushers will rapidly reduce coal, ore and hard rock from maximum feed size of 20mm to fine sand.
In the bauxite ceramic sand production line, the bauxite ceramsite sand or ceramic proppant sand oil is produced. The raw bauxite with sizes about 300 500 mm comes from the mine and generally it has a small amount of water inside. Using the jaw crusher and .

Impact Crusher is based on advanced foreign models, we developed a new and efficient crusher. Processing particle size of not more than 500 mm, not more than 320 MPa compressive strength materials (granite, limestone, concrete, etc.), Crusher for its excellent performance and good performance, widely used in the production of highgrade highways, utilities, artificial sand and gravel, .
crushers is widely used as secondary stone crusher in quarrying, mining, metallurgy, building and construction materials industries. on "rock on rock" and with three crushing chambers, the final products is with cubic shape, PF series impact crusher is especially suiltable for making aggregates used in highway construction.
Impact crusher uses impacting force to treat materials that mainly used for medium crushing and fine crushing for soft and medium hard rocks. In order to make sure the normal work of impact crusher, and prolong its service life, daily maintenance is unnecessary. Keep the following points in mind:

Additionally, with a deep crushing cavity and big Reduction Ratio (Reduction Ratio is broadly defined as the ratio of the feed size to the product size in any crushing operation, which also says that the bigger the reduction ratios of a crusher is, the finer the end products coming out of it is), a fixed crusher .
• As stone passes through a crusher, the reduction in size may be expressed as reduction ratio. • The reduction ratio is the ratio of crusher feed size to product size. • The sizes are usually defined as the 80% passing size of the cumulative size distribution. • For jaw crusher, the ratio can be estimated by the gap.
as the fines contained in the final product can smoothly pass through the crushing tools high throughput capacities (up to 5000 t/h) at low operating costs low specific wear rate due to slow circumferential speeds insensitivity to smeary, ductile, wet and sticky feed materials SCOPEOFAPPLICATION feed size: up to approx. 1500 mm product size: mm

VSI Crusher ( Sand Making Machines ) VSI Crusher( Vertical Shaft Impact) is commonly known as sand making machines, sand maker and shaper. These sand making machines are equipped with original German thin oil lubrication station which uses double oil pumps to guarantee the oil supply through complementation; it can automatically stop operating when there is no oil flow or oil pressure.
ST/AR VSI Crusher: General Application Guidelines REMco ST/AR VSI crushers are rockonanvil vertical shaft crushing machines designed to operate as second, third or fourth stage crushers for processing soft to medium/hard rocks, ores or minerals that contain less than 15% abrasives (silica, alumina, and iron). Maximum feed size is 6" (150 mm) and product sizes can be from 1 1/2" (40 mm) to minus 6 mm.
