System sand machine
System sand machine is the introduction of American Barmac company
famous "stone strike stone" crusher principle and technology by our
company, combined with the actual situation of sand production,
developed efficient stone crushing equipment with the leading level
in the domestic, international. It is widely applicable to all
kinds of rock, abrasives, refractories, cement clinker, quartz,
iron ore, concrete aggregate and other hard, brittle material for
crushing, fine crushing (system sand). On the construction of sand,
gravel roads excellent for the appropriate use.
System pressure-blasting machine work principle:
The material from the hopper into the crusher,via the distributor
the material is divided into two parts, one part was sent from
distributor medium into the high-speed rotation of the impeller,
the impeller was rapidly accelerated, the acceleration up to
hundreds of times of the acceleration of gravity, and then as 60-70
M / s velocity from the impeller three uniformly distributed
channels throwed out, impact with a portion of the falling material
receipt by the distributor around to first break, then impact to
the vortex branch cavity material lining layer, rebounded by
material lining layer, oblique impact to the vortex chamber top, it
changes its direction of motion, partial steering down movement,
emitted from the impeller. Material forming a continuous material
curtain. Such a material suffer in dynamic crushing cavity two
times and many probability impact, friction and grinding effect.
The material being broken discharged by the lower discharge outlet.
with cyclic screening system form a closed circuit, three general
circulation can be broken into 20 mesh. In the whole process of
broken down, material mutual impact and crush, does not directly
touch with metal components, but with material lining friction
layer, and impact crushing, which reduce angle spollution, extend
the time of mechanical wear. Vortex chamber internal clever air
circulation, eliminate the dust pollution.
System sand machine structure:
Sand making machine is mainly composed of: a feed hopper, feeder,
vortex dynamic crushing cavity, an impeller body, spindle assembly,
chassis, transmission device and a motor of seven parts. Wearing
parts mainly include: the impeller, the impact block,
wear-resistant block, runner plate, backplate.
1) the machine is developed in the new ninety, fine crushing
equipment, but also the world widely used instead of cone crusher,
roller mill, ball mill.
2) novel structure, unique, stable operation.
3) small energy consumption, high yield, high crushing ratio.
4) device has the advantages of small volume, simple operation,
convenient installation and repair.
5) with shaping function, a cube-shaped products, packing density.
6) in the production process, stone can be formed to protect layer
bottom, no wear, durable.
7) the less easy-wore parts made by wear-resistant materials, small
size, light weight, easy replacement of parts.
