ntroduction of Sunstone Sand Making Machine The SUNSTONE Sand Making Machine is improved on the basis of Germany high technology, which is highly-efficient and superior in performance. The SUNSTONE sand making machine is widely used to produce sand and stone for highway, high-speed railway, city project, hydropower dam constructions, and concrete mixing plant, and its also widely used in sand making and stone reshaping industry. Features of Sunstone Sand Making Machine 1. the oil needed is supplied by two oil pumps, and the machine stops automatically if there is no oil; the motor can be heated automatically in winter to ensure the normal working of the machine. 2. Hydraulic lifting system to check and replace the spare parts, thus its very easy and simple to maintain. 3. the bearing is of SKF and TIMKEN brand to ensure the normal working of the machine. 4. Special feeding structure; rock on rock, and rock on iron to make the stones crushed and reshaped. 6. Unique dustproof seal system to prevent the dust getting into the spare parts. 7. unique design of material bumping angle reduces the friction between raw material and spare parts, extending the working life of spare parts and cut the cost. Working Principle of Sunstone Sand Making Machine 1. Central feeding: Raw materials fall down into the feeding hopper, then enters the impellor through central entrance inlet, thus the material being accelerated by the high-speed impellor and being thrown out at the speed of 60-75m/s. It is crushed when hitting the impact plate, and the end products comes out from the discharging outlet. 2. Ring feeding:Raw materials fall down into the feeding hopper, and the materials are divided into two parts by a special plate. Some materials enter the impellor through the center of the plate and the other part of materials falls down from outside of the plate. The materials thrown out earlier crush the materials down from outside, thus the materials crushed and re-crushed.
