Zhiwei drum desander and sand screen machine;

Cylinder sand screen

Main features of sand screening machine:

1. High integrity: All systems except the finished product stacking belt conveyor are integrated into an integral framework, which not only ensures the integrity of the equipment, but also leaves appropriate maintenance and inspection space. High integrity is convenient for storage or transshipment on the construction site, convenient and safe.

2. Working reliability: The core screening system adopts the mixing principle of a mixer, and the raw materials are rolled and rubbed by continuous spiral blades in the mixing drum, which has strong natural reliability.

3. The rolling screen drum is placed horizontally to ensure that the material flow rolls between the spiral blades of the screen drum for more than four times, so that the sand material rolls repeatedly and is fully dispersed and screened. It is different from the phenomenon of incomplete screening and mixing caused by collision and extrusion of large and small materials or vibration and jumping of large and small materials caused by inclined rolling screen or inclined vibrating screen.

4, use economy:

① The storage hopper has a volume of 8M3, which is convenient for the loader to reasonably arrange the feeding time between the main equipment (such as mixing station) and stone washing machine, and avoid frequent transposition of the loader between different feeding points and raw materials. The width of the hopper mouth is greater than 3m, which also makes the loader easy to feed and reduces the labor intensity.

(2) The screens are connected by replaceable parts, which is convenient for replacing or replacing worn screens with different mesh sizes.

③ Raw sand can be screened into three-grade finished products at one time according to different requirements of users, such as the three-grade finished products of Chengde Municipal Company: ≤5mm, ≤35mm, > > 35mm..

5. The finished sand can be stacked or put into a box or barrel (for example, put into a sand hopper of a dosing machine).

Operation and instruction of sand screen machine

1 Zhiwei sand screening machine, also known as Zhiwei dry land sand screening machine ship, is a kind of sand and gravel separation equipment suitable for rivers, reservoirs and coal yards.

2 Zhiwei sand screen is divided into electric sand screen and diesel sand screen according to the power system.

3 According to the feeding amount, it is divided into 30 shovel screen sand machines and 50 shovel screen sand machines.

Zhiwei sand screen (sand screen ship) components: diesel engine reducer conveyor belt, hull hopper, rotary screen conveyor rod. (2 diesel engines, 3 reducers and 3 conveyor belts)

Working principle of Zhiwei sand screen: the scraper shovels wool into the hopper and conveys it to the rotary screen through the conveyor belt. The sand separated from the wool is conveyed to the sand grate through the outlet, and the stones are conveyed to the stone grate through the outlet. The work is finished. Each shift is operated by 1-2 people. The model is simple in structure, economical and applicable, and easy to operate.

This machine is used in highway, railway construction, real estate construction and other processes. , the sand and gravel are cleaned and separated, which meets the requirements of the national special construction standards of Sand for Building and Pebbles and Gravels for Building.

7 Note: (1), people under 8 years old and over 50 years old are not allowed to operate or maintain this machine.

(2) It is forbidden to operate this series of machinery without professional training or after drinking.

(3), sand screen machine maintenance, all machinery must stop running, before.
