The Blake crusher is considered the most common one in which the swinging plate is pivoted at the top [2] This crusher can be realized in two forms as The crushing surface in a jaw crusher consists of two rectangular plates one fixed crushing face and an inclined mobile face which moves a small distance back

He goes so far as to say the terms jaw crusher and Blake crusher are synonymous Transforming the industry In 1872 Blake applied for an extension of his patent At the time the law required those applying for patents to submit the labor costs and value of the invention to the Commissioner of Patents for the Patent and
The initial breaking up of ore is done by one of two types of jaw crushers which are known as single toggle and blake jaw crushers The central difference is their crushing procedures Single toggle jaw crushers are used for the simplicity of design where the movable jaw moves at the top of the crusher
• In Blake jaw crusher the greatest amount of motion is at the bottom • It is divided into two types 1 Single toggle 2 Double toggle 16 i SINGLE TOGGLE • In it swing jaw is suspended on the eccentric shaft which leads to a much more compact design • The swing jaw suspended on the eccentric undergoes two types of motion swing
Blake crusher the swing jaw is fixed at the upper position; Dodge crusher the swing jaw is fixed at the lower position; Universal crusher the swing jaw is fixed at an intermediate position Suitable for crushing hard and abrasive materials jaw crusher is commonly used as primary crushers in quarrying mining recycling due to their reliable
Jaw crusher is primary crushing equipment used for crushing of materials Blake type crusher with movable jaw pivoted at top giving greatest movement to small lumps This type of crusher has a movable crushing plate usually corrugated fixed in a vertical position Eccentric mechanism is used to move jaw in a reciprocating motion
Dimensional data of a typical double toggle jaw crusher are used in the derived mathematical expressions to demonstrate their application Moreover starting with the equation for the angular velocity ratio of the moveable jaw with respect to the input crank an expression for the ideal mechanical advantage of the crusher is derived
The Stag jaw crusher shown in Fig has a fixed jaw and a moving jaw pivoted at the top with the crushing faces formed of manganese steel Because the maximum movement of the jaw is at the bottom there is little tendency for the machine to clog though some uncrushed material may fall through and have to be returned to the crusher
Blake type crusher where the movable Jaw plate is pivoted at the top end near the gape or feed opening b Dodge type crusher a Blake crusher type with a movable jaw plate pivot located at
A jaw or toggle crusher consists of a set of vertical jaws one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism Blake jaw crusher In the
Dodge Jaw Crusher Similar to the Blake crusher the Dodge crusher has a movable jaw that moves towards and away from the stationary jaw and is preferred for crushing softer particles Universal Jaw Crusher This type has a "V" aligned fixed jaw and a movable jaw on an eccentric shaft creating an elliptical motion
A laboratory Blake type Jaw crusher Figure 1 with an opening of 10 Â 12 cm and a jaw length of cm was used in the experiments Three different size fractions À 90 þ 50 mm À 50 þ
8 As the moving jaw is pivoted at the top the amplitude movement is largest at the bottom The maximum distance the moving jaw travels is called throw of the crusher 9 Gape is defined as the distance between the jaw plates at the feed opening end 10 The Blake crusher has a varying discharge opening This distance between the jaws in
Eli Whitney Blake invented patented and sold the first actual rock crusher in 1858; it was known as the Blake Jaw Crusher Blake s crusher was so influential that today s models are still compared to his original designs This is because the Blake Jaw Crusher integrated a key mechanical principle—the toggle linkage—a concept students
A jaw or toggle crusher consists of a set of vertical jaws one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism Blake jaw crusher In the
Blake type jaw crusher primary crushers in the mineral industry; attains maximum amplitude at the bottom of the crushing jaws as the swinging jaw is hinged at the top of the frame These crushers are operated by and controlled by a pitman and a toggle The feed opening is called gape
A Blake jaw crusher had the following dimensions Gape = 160 cm open set = cm close set = cm The width of the hopper was times the gape The ore contained 20% material minus cm The bulk density of the rock was t/m 3 and the nip angle ° Determine
The Blake Jaw crusher is the commonly used crusher In Blake Jaw crusher feed is admitted between the two jaws set to form a V open at the top One jaw the fixed or anvil jaw is nearly vertical and does not move; the other the swinging jaw reciprocates in a horizontal plane It makes an angle of 20º
Blake Crushers are operated bytoggles and controlled by a pitman These are commonly used as primary crushers in themineral industry The size of the feed opening is referred to as the Jaw Crusher Input Sheave/Flywheel Rotational energy is fed into the jaw crusher eccentric shaft by means of
