What are the criteria for assessing the environmental performance of sand-making machines

As a naturally occurring stone found predominantly in riverbeds and hilly terrain, pebbles are readily accessible for extraction. Serving as a vital construction aggregate, pebbles undergo crushing, sand-making, and screening processes to yield high-quality sand. The resulting sand exhibits uniform particle size, excellent abrasion resistance, and low silt content, making it an ideal material for sand production. However, with increasingly stringent environmental regulations in recent years, the environmental performance of sand-making machines has garnered significant attention. What, then, are the criteria for evaluating the environmental friendliness of a sand-making machine?

The environmental effectiveness of pebble sand-making machines manifests primarily in two aspects during production: low noise levels and minimal dust pollution. Consequently, assessing their environmental impact requires consideration of these two factors, as outlined below:

1. During operation, both the start-up and running noise levels of the pebble sand-making machine must comply with noise emission standards to meet environmental requirements.

2. The machine must generate minimal dust pollution during operation. While this is difficult to assess during initial testing, it can be evaluated through structural analysis. Generally, this involves examining the exhaust system and whether a dust collector is fitted. An efficient exhaust system coupled with advanced dust removal equipment will significantly reduce dust pollution during production.
