General
The single toggle crusher has a very large crushing capacity because it is
large in opening size, large in crushing throw near around the inlet and small
in the whole nip angle. Since it is simple in mechanism and light in weight as
compared with the blake type, this machine is very easy to handle. For this
reason, this machine has established its position as a primary crusher in the
aggregate production equipment. The doubletoggle (blake) crusher having
conventionally been used is now used only in limited applications such as
aggregate production plant for dam construction and mining industry.
The tendency toward the largesize single toggle crushers has been
accelerated by the factors such as the establishment of its position of this
type crusher in the stonequarrying industry, tendency toward the largescale
stonequarrying industry and tendency toward the largesize raw stone in
keeping with the reduction in raw stone quarrying cost that give impetus to
each other. Consequently, the largest machines having been kept on actual
manufacturing records reach the size of 1,500 mm × 2,000 mm. For the
structure, the steel plate frame type and swing jaw frame type have been in
popular use, thanks to the rapid progress of welding techniques. The cast

Capacities are based on ordinary limestone not containing wet fine particles.

Therefore, it is the crushers which it was suitable for as lime stone crushing
equipment, crushing plant, a primary crush use such as an aggregate plant of
dam construction most.
STRUCTURE
Frame
Frame is one structure of the core box that combined steel plates for welding
structure by welded, moreover put rib inside, and it is with extremely strong
design. In addition, it gives postweld heat treatment, and the residual stress
has been removed. Large-scale machines more than FS-4840 types are frame
two-piece housings or be division into 4s to a side frame, front and back part
frame and tighten each frame with bolt.
Swing jaw
It is designed strongly to bear strong enough crushing force in box section
structure made by cast steel.
Eccentric shaft
Because it did an eccentricity revolution and moved the swing jaw and
received crushing force and an impulse force strong directly, a material used a
special forged steel, and finished precisely.
Bearing
Be used spherical roller bearing with a main-bearing and swing jaw bearing.
A roller bearing is chosen to have a big safety factor and endurance for
crushing power with bombardment. Lubricating becomes oil filled system.
Moreover, maintenance management is very easy because a bearing part
completely prevents a trespass of dust and run off of oil by a labyrinth seal.

Toggle plate and seat
Plate is made by special cast iron, and a seat is made by forging steel. In the
contact part, be taken hard facing both. A contact part of a seat and plate is an
oilless system(patent No.424746), therefore do not need oiling, and there is not
sticking by running out of oil. Moreover, maintenance is simple, and there is
not that it pollutes floor with an oil at all. Moreover, toggle plate becomes
somewhat lower with strength than other parts. A plate chews metallic material
in crushing room, and it is with the protective device which it does breakage,
and prevent damage for the other body when abnormality load hung.
Flywheel
It establishes at both ends of the eccentric shaft, and one side serves as a V
pulley. It keeps enough flywheel effect to let you show powerfully crushing
power. Moreover, flywheel becomes balance weight for unbalance depending
on eccentricity movement.
Almost assume a crushing ratio 3-7 with our company crusher, and design for
about 5 in an average. Judging from the efficiency of a machine and crushing
ability, an application except this crushing ratio is unfavorable. When it uses
with a particularly big crushing ratio (the smallest set of a catalog mention), the
crushing room is in a condition of overcompression, and there is even that it
progresses for trouble of a machine. Therefore, can change an eccentricity of
the eccentric shaft with FS type. When it does the special method of
application, design adds to the machine which fitted the condition.
