There are many strict requirements for the particle shape and gradation of aggregates in highway construction, especially for the content of flat-elongated particles in basalt(diabase). In order to satisfy the demands for the size, gradation, shape, consistency, cleanness and 0.075㎜ particles content of the crushed aggregates, Camelway Machinery configures the new style vertical shaft impact crusher to produce high quality manufactured sand so as to better meet the cement, asphalt and other sand aggregate standards in highway construction.
In the production line, our technical staffs mainly configure the vibrating feeder, jaw crusher, hydraulic cone crusher, circular vibrating screen, vertical shaft impact crusher(sand making machine), belt conveyor, etc. It is suitable for crushing granite, basalt, diabase and other kinds of hard materials, and it can be applied in highway, urban construction, airport construction industries.
The raw stone materials firstly are sent to jaw crusher for primary crushing and then the secondary crushing process is finished by the hydraulic cone crusher. Then, the semi-products will be screened by the vibrating screen--the materials with a size over 40㎜ will be transferred back to the cone crusher for further crushing to form a closed circuit while the materials with the size below 40㎜ will be sent to the VSI Crusher to produce manufactured sand. After the process, the screened materials over 20㎜ size will be back to last step for crushing and shaping again in the VSI sand maker while the below 20㎜ size are conveyed to the corresponding end products piles respectively.
The aggregate production line for highway construction that Camelway provided has fully considered the sand aggregate standards of highway construction industry. It has the advantages of high automation degree, high productivity, low operation cost, high profits, etc. What’s more, its discharging particles is adjustable, and our VSI crusher just needs one drive motor with a low energy consumption but a high crushing ratio. Except for the crushing function, the also has the aggregate shaping function, the manufactured sand it produced has a good and uniform particle shape that fully conforms to the highway aggregates standards.
