How to Adjust Water Flow in a Sand Washing Machine: A Comprehensive Practical Guide
In modern sand processing, the sand washing machine is a cornerstone piece of equipment. Its primary role is to remove impurities such as silt, clay, and dust from raw sand, producing high-quality washed sand suitable for construction, concrete, and industrial use. Among all factors affecting the machine’s efficiency, water flow adjustment is one of the most critical. Correct water flow ensures thorough washing, reduces water and energy consumption, minimizes wear on equipment, and prolongs service life.
How to Adjust Water Flow in a Sand Washing Machine
This guide provides practical, step-by-step advice on adjusting water flow in sand washing machines, along with tips drawn from real-world operations.
1. Understanding the Role of Water Flow
Water in a sand washing machine is not just a cleaning medium—it acts as a carrier for impurities. The right flow ensures that dirt and silt are effectively separated from the sand.
Problems caused by incorrect water flow:
Too little water: Sand may remain partially dirty, with residual mud and clay sticking to grains.
Too much water: Excessive water increases operational costs, can cause sand loss, and accelerates mechanical wear.
Benefits of proper water flow adjustment:
Produces clean, uniform sand that meets construction standards.
Reduces water and electricity usage.
Minimizes wear on pumps, impellers, and other components.
Improves overall washing efficiency, especially for fine sand.
2. Inspect and Adjust the Water Inlet Valve
The water inlet valve is the primary control point for water flow. Here’s how to adjust it correctly:
Locate the main inlet valve connected to your water source.
Gradually open or close the valve to increase or reduce water supply.
Observe the water level in the washing tank. Ideally, the water should fully cover the sand layer without overflowing.
Real-world tips:
Machines with multiple inlets require balanced adjustment; uneven water flow can cause sand accumulation in one area and uneven washing.
