VSI new type of sand making machine is a kind of new generation of sand making machine that Shanghai Longzhen Heavy Industry Co.,Ltd brings in foreign advancing technology and integrates the characters of national stone to apply to Chinese clients, it is high performance sand making machine that at present is produced by sole company and has world advancing level. VSI new type of sand making machine has the advantages of higher productivity, good product grain shape and low use cost compared with domestic like product. This machine especially supplies superior ore aggregate for highway    ` railway` high buildings` municipal administration` hydropower dam construction and concrete mixing plant, it is the top choice of equipment in the field of the manual sand making and stone shaping

1.Compared with the traditional equipment under the same power, it has the characters of high capacity and high productivity, productivity has been increased by % and stable;
2.Product’s grain shape is superior-product is cubic, the grain shape is good, graduation is prosper and fineness modulus is adjustable;
3.Consumption of wearing parts is low, cavity’s design is sound, it decreases the direct touch between materials and wearing parts and it reduces the wearing of wearing parts much more;
4.Hydraulic drive cover device, it is more convenient to replace wearing parts;
5.Thin oil lubrication, automatic maintenance-thin oil transmission has unparalled advantages of high transmission efficiency and good cooling effect, under the situation of the same capacity, it can lessen power consumption by 40%. Double oil pumps are complimentary to ensure oil supply, it will shut down automatically when there is no oil flow and no oil pressure; oil cooling and heating apparatus guarantee bearing lubrication is always in the optimum statement. So it solves the problem of bearing heating thoroughly, makes the mainshaft keep constant tempreture and prelongs maintenance period and use life.’
‘Massy front-housing base, two flange set pack motors whose two ends are symmetrical to be installed, multiple-groove sheave drives high speed rotating rotor, stone materials are casted from casting opening tangent direction, blow the anvil ring and stone materials are crushed by themselves.’
‘VSI sand making machine consists of feeding opening` unloading cone` impact liner` rotor` motor` vertical shaft` frame and discharging opening.
