When processing sand and gravel, choosing environmentally friendly and cost-effective equipment requires comprehensive consideration of output, energy consumption, loss, finished product quality and environmental performance. The following recommended equipment types and specific brand cases are for reference:

Recommended equipment type

High-efficiency and environmentally friendly sand making machine

VSI sand making machine: The processing capacity is 60~650t/h. In environmental protection operations, a pulse dust removal device is installed at the entrance, or an external sprinkler device is used to reduce the amount of dust when the material enters the deep crushing cavity, and the amount of dust is further reduced through the air self-circulation system during sand making.

HVI sand making machine: The processing capacity is 70~585t/h, and it also has efficient dust removal and environmental protection performance.

Hydraulic cone crusher

The hydraulic cone crusher adopts an advanced PLC electrical system, which can continuously monitor the crusher and provide alarms, display operating parameters, and the operator can understand the operation of the crusher in real time, thereby simplifying the production line operation, reducing operating risks, and improving the safety performance of the crushing production line.

The material is crushed by the principle of laminated crushing, with high crushing efficiency and low wear of wearing parts; the finished product after crushing is cubic and has a high fine-grained content, which can meet the use requirements of high-quality aggregates.

Hydraulic roller sand making machine

A relatively economical sand making equipment, which crushes and grinds the material through the mutual friction of two grinding rollers. The material entry and exit are completed in the crushing chamber, which greatly reduces the amount of dust.

The roller skin is made of high-chromium wear-resistant material, with low wear rate and high equipment utilization rate. It supports high-hardness stone grinding, such as granite, basalt, iron ore and other hard stones are within its applicable material range, and the processing effect of brittle materials is better.

Good sealing performance, built-in dustproof plate structure in the sand making process, avoids dust leakage and locking noise in the sand making process. Long service life and low cost, the roller skin can be repaired by surfacing welding, durable, and reduce the wear cost of wearing parts.

Mobile crusher

The jaw crusher, cone crusher, impact crusher, sand making machine and other equipment can be matched with the mobile crusher to become a mobile crushing station, which can be started and moved at any time without being restricted by the site.

It has stronger adaptability to the site and can be directly driven to the site for operation, reducing the cost of material transportation.

Specific brand case

Sand making machine of Liming Heavy Industry:

High output: Different types of sand making machines can process up to 100 tons to 300 tons of raw materials per hour, which can increase the output by more than 50% compared with traditional sand making machines.

Energy saving and consumption reduction: It adopts single power transmission and only requires one motor. Compared with sand making machines with other complex power systems, it can save more than 40% of energy. Low noise, only 1.68 kWh of electricity per ton of stone.

Low loss: As a key vulnerable component, the roller skin is made of high-quality high-manganese alloy material and thickened design, with a long wear-resistant period of up to 3 years. The loss of wear-resistant parts per ton of sand calculated by output is much lower than that of other sand making machines.

Intelligent operation: Equipped with advanced intelligent control system, the intelligent one-button start cabinet is easy to operate and can also realize remote monitoring, improving the operation stability and production safety of the equipment.

High-quality finished sand: The quality of the finished sand produced meets the standards and can meet the strict requirements of construction engineering, road paving and other fields, winning a good market reputation for the company.

Simple structure and convenient installation and maintenance: The structural design is simple and reasonable, which makes installation easier and faster, without complex infrastructure and large-scale installation equipment. The key components adopt modular design, which is easy to disassemble and assemble, and maintenance personnel can easily inspect, maintain and repair the equipment.
