Vertical Shaft Impact Crusher

1.Vertical Shaft Impact Crusher is also called Sand Making Machine, are widely used in metal and non-metallic minerals, highways, utilities, refractory material, abrasives, glass raw materials, urban construction aggregate, artificial sand and a variety of metallurgical slag crushing and coarse grinding operations, especially for medium hard, special hard and abrasive materials, such as silicon carbide, carborundum, sintered bauxite, magnesite, etc. It is superior to other types of crushing machines. Equipped with hydraulic protection jaw, it can process a variety of metallurgical slag.

2.Brief Introduction: The vertical shaft impact crusher, also called sand making machine and rubble shaping machine, is a kind of crusher impacted by the materials themselves. It is of high energy but low consumption and of international advanced level developed by introducing foreign outstanding technology of the same type of products. At present, it is the most advanced and practical equipment for medium-sized and fine crushing and shaping.

Application: It is widely used for medium-sized and fine crushing and shaping in the following industries: minerals, quarry, abrasive, cement, refractory materials, alumina, quartz sand, and emery, glass and so on.

Operating Principle: The materials fall into the impeller from the head of the machine and with the function of high-speed centrifugal force, they strongly hit against and highly grind the other parts of the materials bypass flowing around the impeller in an umbrella form. After mutual impaction and between the impeller and the machine shell, the materials will move like a vortex and will be impacted, rubbed and pulverized many times. Then they will come to the required fineness controlled by screening equipment, and discharge from the bottom of the machine.

3.Advantages and characteristics:
(1)With alloy blade in hammer, extend;
(2)Lubrication system ensures more stable operation;
(3)Adjustable hopper ensures the best inlet amount;
(4)Cubic particles;
(5)High output and low power;

Brief introduction
(1)Novel and distinctive design. Simple and reasonable structure. Smooth operation and low operating cost.
(2)Two states of "stone hitting stone" and "stone hitting iron" can be changed freely. The equipment can be applied to manufacturing sand as crushing stones. The "stone hitting stone" technology not only reduces parts friction but also cuts down manufacturing cost.
(3)Low energy consuming, high yield, large breaking proportion and energy save.
(4)The equipment is capable of shaping out products. Products take a cubic shape and enjoy high bulk density.
(5)During the manufacturing, stone materials can form a protective bottom to avoid wearing the equipment, so the equipment is durable in use.
(6)Few abrasive parts are made of wearing resistant material of special hardness, which is small in volume, low in weight and easy to be changed.
(7)Automatic air circulatory system can purify concentrative screening powder
(8)Water content of the material exerts little influence, and maximum contenting water can be 8%.
(9)Lubrication oil station is adopted to lubricate the major bearing in circulation to ensure a constant oil supply. It can realize automatic control and accident alert.
(10)The upper is uplifted by hydraulic system, and operation is simple.

4. Vertical shaft Impact Crusher introduces German technology. It is with many patents and is key equipment in sand making area. It is a kind of totally new high efficient crusher.
It has the following features:
(1). Rotor with deep chamber increases 30% capacity after perfect design.
(2). Side plate direction can be changed to increase material utility ratio. Operating ratio can be increased 48%.
(3). Worn hammer with combined type is only changed to reduce operating cost 30%. Another pair of vice hammer is added to prevent from damaging main hammer and side plate.
(4). The key wear resistant material is made of material resistant to wear and high temperature from America.
(5). Rhombus shape impact plate is used to prevent side plate from being damaged.
(6). Bearing is famous international brand imported from Japan, Sweden, America, etc.
(7). Perfect discharge and smooth curve reduce resisting force when material flows, so capacity is increased greatly.
(8). Spread dish with double purposes can make two feeding ways change easily.
(9). Special seal structure under main shaft guarantee no oil leak without seal.
(10). Japanese hydraulic opening cover device is originally imported. The cover is moved easily and inspection of inner part is easy.
(11). Motor with high grade of protection is selected. The motor has features of high efficiency, low noise, etc. The motor complies with IEC, insulation grade F, protection grade IP54/55.

5.Sand Making Machine:
Sand Making Machine is of high-power and low-consumption, which is designed depending on several years’ hard work and study of mechanical mining equipment. Sand Maker absorbs the advanced technology of the same products of Barmac Company of America. Now it is of international level. Sand Making Machine plays an important role in crushing minerals into pieces. Vertical shaft impact crusher is widely used in all kinds of mineral, cement, bauxite chmotte, carborundum grain, glass raw material, construction sand, stone stock and all kinds of metallurgy slag, especially carborundum, sintered bauxite and other materials with features of very hard and anticorrosion. And Sand Making Machine is more productive than other crushers.

Working Principle:
Stone less than 50mm enters sand making machine through conveyor belt. Stone is crushed by hitting other stones. Material falls down to impellor cavity. Under great centrifugal force, it hits material that coming downwards. After hitting each other, they force a vortex between impellor and shell, and hit each other several times. Finally, smaller stone comes out and goes to vibrating screen. Satisfactory material is transported to sand washing machine. Overlarge material will go back to sand maker to be crushed again. Output sizes can be made according to customers’ requirement. If input size is larger than the designed size, other crushing equipment will be necessary.
Characteristics:
Simple structure and low operating cost;
High efficiency and low consumption;
Sand Making Machine has the function of fine crush and crude grinding;
Slightly influenced by the moisture content of material and the max moisture content can be 8%;
More suitable for crushing mid-hardness and high-hardness materials;
Cubic shape of final products, high density of piling up and low iron pollution;
More wearable and easy maintenance;
Low working noise and light dust pollution.
