Types of Juicers - Centrifugal, Masticating and Twin-Gear Juice Extractors
Overview of Main Electric Juicer Types
Think through your juicing habits to decide what kind of juicer is the best for your needs and budget. For the most health conscious it is good to know that juicers that operate at low speed thus generate the lowest possible heat and (triturating aka twin-gear juicers) protect the nutrient content in the gained juice.
In centrifugal juicers there's a round shredder disc with sharp blades that spins at high speed while grinding and grating the fruits and vegetables into tiny pieces.
The centrifugal force generated by the high speed revolution (RPM=revolution per minute, rate of revolution of the juicer's motor) pushes the juice through a fine-screen sieve separating the juice from the pulp. The juice flows out through the spout in the front of the machine into a glass you place there.
they're cheaper than other juicer types - this perhaps the most important benefit for budget-conscious buyers: centrifugal juicers sell for around $90-220.

Masticating (Single-Gear) Juicers - Less Heat
The single most important benefit of masticating machines is that the slower juicing process (Low RPM juicer) results in more vitamins, enzymes, minerals and trace minerals contained in the juice. The lower rate of rotation generates less heat and injects less oxygen into the end product protecting the nutrients in the juice and providing you with a more healthier juice drink.
There are two types of masticating juicers:
Price range of electric masticating juicers: cc. $150 - 350. There are some manual masticating style juicers that cost less: e. g. the Easy Health Juicer is a single auger hand-operated unit available mostly in the UK and other European countries. (retail price is around 30 GBP).
The Oscar Manual Juicer ( a hand-operated version of the Samson 6-in-1 made by Oscar Vitalmax) sells for around $165 - $180.
On the other end of the spectrum are the all-stainless steel high-end Super Angel / Angelia Juicer models with cc. US$ 870 - US$970 price tag.

Twin Gear (Triturating) Juicers -Slow but Provide the Healthiest Juice
During the first step the twin-gear juicer crushes the vegetables and fruits pulverizing them into a pulp, than it extracts the juice in the second step. These low-heat juicers help to maintain the high nutrient content of the raw foods.
Several single auger or twin gear juice extractors juce wheatgrass well, but if you want to juice large quantities of the green blades regularly it's best to buy a dedicated wheatgrass juicer.
Twin-gear juicers cost more than centrifugal or masticating machines: cc. $400-800.
Other Types of Juicing Machines
Commercial units (raw-food restaurants, juice shops) use high-yield hydraulic presses like the Norwalk Hydraulic Press Juicer to make vegetable and fruits juices. These heavy duty machines cost way more than the other types of juicers described above. More on Commercial Juicers.
Cafes, restaurants and juice bars use high-volume centrifugal fruits juicers or dedicated commercial-grade citrus juicers to be able to serve customers with freshly made orange juice on a daily basis.
Steam juicers deserve to be mentioned too. Steam juicers are stainless pot-like appliances that contain three parts: the bottom container is for boiling water to generate steam. You place the fruits or vegetables in the steamer basket that comes on the top of the water container. The juice will seep out of the fruits, vegetables after about 30 minutes of steaming into the center juice container.
A stainless steel steam juicer usually costs about $80 - 160.
Last but not least manual juicers such as manual citrus presses offer an inexpensive, simple way for juicing.
