Double Toggle Jaw Crushers use two toggle plates and hence the name. Such crushers do not rub the jaw plates with the material to be crushed and hence lead to lesser production of dust (very small crushed size), higher jaw plate life and lesser power consumption.
This type of Double Toggle Jaw Crusher uses grease for the lubrication of the four nos. self aligning double row ball bearings. This is particularly useful for higher altitudes and its simple design and ease of operation makes it particularly suitable for sites far from towns or geographically difficult to access.
