VSI5X Vertical Shaft Impact Crusher is the latest efficient sand making machine based on the thorough research on the production features of every kind of traditional sand-making machine from crushing equipment experts of Liming Heavy Industry .It is integrated with three kinds of crushing modes and becomes core equipment in sand making industry. Through special optimal design, throughout capacity of material is improved by about 30% for deep-cavity shape rotor for VSI5X sand making machine. Innovation design is adopted for guard board, improving service life by more than 48%. Addition of secondary hammer can effectively avoid damaging riser after main ram is worn. The most crucial wear resistant materials adopts highly anti-wear and heat-resisting material used in important industries in America. Hydraulic hood opening device adopting originally imported parts can facilitate checking and maintaining equipments.
VSI5X Vertical Shaft Impact Crusher is widely used in every kind of metallic and nonmetallic minerals, cement, refractory materials, grinding, raw material of glass, building aggregate, machine-made sand and metallurgy etc. It is applicable to intermediate-fine operation for each kind of minerals and rocks with different intermediate-fine hardness such as iron ore, nonferrous metallic ores, carbon silicide, bauxite, quartz sand, brown aluminum oxide, perlite, basalt and other high-hardness material.
1. After deep-cavity shape rotor is optimally designed, throughout capacity of material is improved by about 30%.
2. After guard board is partially worn, its direction can be changed upward and downward, to improve usage rate of material; service life can be improved by more than 48%.
3. Combinatory ram design: only need to replace the part of worn ram, which can lower using cost by more than 30%. Furthermore, addition of secondary ram can effectively avoid damaging riser after main ram is worn.
4. The most crucial wear resistant materials adopts highly anti-wear and heat-resisting material used in important industries in America.
5. Adoption of rhomboid impact block can avoid damaging riser after material is impacted and worn.
6. Bearing is selected from international brands from Japan, Sweden and America etc .
7. Optimal ejecting port and internal smoother curved form design can lower flow resistance of material and greatly improve throughput capacity of material.
8. Dual purpose bulk panel ensures simple operation and convenient conversion between two kinds of feeding modes.
9. Special sealing structure at lower end of spindle guarantees no leakage without oil sealing.
10. Hydraulic hood opening device adopting originally imported parts from Japan makes movement of upper cover convenient and rapid, which saves strength when replacing and maintaining parts inside the main body.
11. Selection of high degrees of protection motor. Such type of motor has the features of high efficiency and low noise, in accordance with standard of International Electrotechnical Commission (IEC), F grade insulation and IP54/55 degree of protection.
Main parts of VSI5X Vertical Shaft Impact Crusher are as below: stand parts, spindle assembly, rotor part assembly, drive motor part, stand assembly (including upper and lower stand parts), hydraulic jacking swiveling mechanism and running-board bracket at both sides. Supplementary part has electrical system and lubrication system.
Working principle for full central feeding of VSI5X series of new type sand making machine: material drops into feed hopper and enters rotor rotating at high speed through central feeding hole before fully accelerated and thrown out by ejecting port. It is firstly pounded with some rebounded material which then freely drops; then all of them are impacted onto vortex liner in surrounding vortex cavity (or onto reaction block): they are firstly rebounded to top part of crushing cavity, then deviated and moved downward and heavily pounded with material ejected from flow passage of the impeller to form continuous material curtain and then discharged from discharge opening at the lower part.
Working principle for central feeding accompanied with annular cascade feeding for VSI5X series of new type sand making machine: material drops into feed hopper and drops down through annular hole and is divided into two strands of material by bulk panel. One strand of material enters the impeller rotating at high speed through material-distributing panel; the other strand of material drops from the surrounding of material-distributing panel. Material entering the impeller is rapidly accelerated in the impeller and is thrown out at high speed: it is firstly impacted and crushed with another part of material freely dropping from the surrounding of bulk panel; all of them are impacted onto vortex liner in surrounding vortex cavity (or onto reaction block); they are firstly rebounded onto top part of crushing cavity, then deviated and moved downward, hit with material ejected from flow passage of the impeller to form continuous material curtain and are discharged through discharge opening at the lower part.
1. VSI5X Vertical Shaft Impact Crusher can be installed on firm reinforced concrete foundation and also can be installed on steel-structure stand. Depth of the foundation can be decided by users according to situation of local soil and environment condition.
2. To avoid accumulation of crushed material, there should be enough space under crusher to install conveying equipment. Specific size can be confirmed by users according to supported conveying equipment.
3. Oil returning port of thin oil lubrication station must be lower than oil outlet of equipment. Oil return pipe in the middle cannot be higher than the height of oil outlet to avoid unsmooth oil return which can cause blocking.
