Factors Affecting National-standard Sand Producing of Sand-making Machines
With increasing demand sand and stones of construction, high way, railway and other industries. Many people choose river gravel, pebbles for sand making. Sand making has complete set of technology, complete process. For clients knowing little, our specially established clients serving center will offer you site investigation, and guidance for purchasers who are willing to invest but knowing little in sand making machines.

Sand making machines play vital roll in sand making line and stone processing line. Processing capactiy of sand making machines will be introduced first. Processing capactiy of sand making machines refers to amount of materiasl crushed in unit time, t/h is the commonly used unit. Thus, the most important issue is to increase the production capacity. First, we should have a general idea upon factors influencing processing capacity of sand making machines so as to move with certain targets.

Generally speaking, there are many factors affecting production capacity of sand making machines, 6 factors are listed as follows and they are introduced as follows and related soloving plans are fowarded.

(1) Hardness of materials. Materials with higher hardness will be difficult for crushing with more damage to equipments. With slower sand making speed, capacity will be weaker. This requires us to choose suitalbe materials.

(2) Composition of matials, while there is more powder involved in materials, sand making will be affected more severely. As these powder will easily affect transportation. Thus, materials with big proportion of powder should experience screen first so as to slect powder from materials and guarantee common operation of sand making machine.

(3) Fineness of materials after sand making has high requirements to finess, that is to obtain smaller sand making capacity with finer materials. These are up to concrete requirements of ore selection, in case of special requirements, ordinary fineness should be set as mediate level.

(4) Stickness of materials. With higher stickness, materials are more easy to stick to equipments. Sticky materials in sand making machines are easily to stick to the inner side of crushing cavity. If not deleted in time, it will severely affect working efficiency of sand making machines and regular operation will be disturbed then. Thus, while selecting materials, materials with high stickness should be avoided.

(5) Material humidity, that is materials are likely to stick inside sand making machines while material humidity is high, and plug is likely to happen during discharge and transferring. To solve these problems, tempreture of materials should be controlled strictly during material selection. While tempreture of selected materials is high, percentage of water can be reduced by sunshining and wind drying.

To produce national-standard sand, materials should be selected first, feeding size, required capacity should be selected flexibly according to investment and real working site. Surely, equipped machineries should be confirmed according to this condition.

Sand making machine can produce many sand production materials applied widely in railway track ballast plant, quartz crusher plant, ochre crushing plant etc.
