Using conveyors means increased stockpile capacity and reduces on-site material handling.Jan 28, 2021 The final products of lamination crushing are in good cubical shape. Adopting specially designed crushing cavity according to lamination principle and its matching speed instead of the tradition crushing principle, we can alternatively crush the raw materials. In this case, the crushing ratio and cubical particles content are sharply increased.
Due to the long conveying time and many links in the conveying process, the crushing of bulk grain is unavoidable, and the crushing rate is as high as 35 in the conveying process in serious cases. Therefore, it is urgent for grain depot to solve this problem. The main reason for the higher grain crushing rate is that the structure design of trough chain conveyor is not reasonable enough in.In the proposed approach, a rock crushing zone is introduced at the rock-cutter interface beneath the cutter's rake face, namely the Tip Crushing Zone (TCZ), which, as a destruction kernel, is responsible for both the crushing and chipping phenomena occurring in the cutting process.
