Mineral Salt Lick Block Making Machine: Production Technology and Equipment Selection

Livestock mineral supplementation has shifted from loose powder feeding to compressed block formats. This transition addresses critical challenges in modern animal husbandry—waste reduction during inclement weather, controlled intake rates, and simplified field distribution. The machinery enabling this evolution operates on hydraulic pressing principles, delivering forces sufficient to transform loose mineral mixtures into dense, weather-resistant blocks.

Effective mineral salt lick block production demands equipment capable of generating substantial compressive force. Industry-standard machines operate within 315 to 800 ton ranges, with hydraulic system pressures maintained at 25 MPa

. The pressing process subjects raw material mixtures—typically comprising sodium chloride, calcium carbonate, trace minerals, and binding agents—to sustained pressure, achieving densities of 1.6-2.0 g/cm³

.

Block weight specifications vary by target livestock species and regional feeding practices. Standard configurations produce 2kg blocks for young stock, 5-10kg units for mature cattle and sheep, and 15-20kg formats for extensive grazing operations

. Equipment flexibility allowing mold interchangeability enables single-machine production of multiple block geometries—round, square, and hexagonal profiles—to accommodate diverse market requirements.

Established in 2002 in Tengzhou City, Shandong Province, Zhongyou Heavy Industry Machinery Equipment Co., Ltd. has developed specialized capabilities in hydraulic press manufacturing

. The company’s entry into animal feed block equipment followed its 2006 development of high-speed hydraulic pressing systems, which established its technical reputation within China’s agricultural machinery sector.

Zhongyou’s mineral salt lick block making machine line encompasses six primary models: YZ79-315T, YZ79-400T, YZ79-500T, YZ79-610T, YZ79-800T, and YZ79-1000T

. Nominal force ratings span 315 tons to 1000 tons, with corresponding block weight capabilities from 2kg to 20kg. Each system utilizes four-column structural architecture with dual-beam configuration, providing operational stability during high-pressure compression cycles.

The company’s manufacturing approach emphasizes vertical integration. Critical components including cylinder bodies, piston rods, and hydraulic valve blocks undergo in-house production, with heat treatment and precision machining conducted within company facilities

. Cylinder construction utilizes thick-wall seamless high-strength alloy steel, with internal surfaces processed through honing to achieve mirror finishes—extending seal lifespan and maintaining pressure integrity

.

Zhongyou equipment incorporates PLC-based control architecture with touchscreen interfaces, enabling parameter adjustment for pressure, stroke length, and dwell time

. Standard configurations achieve production rates of 3.5-4 cycles per minute, with servo-hydraulic drive options available for energy-sensitive operations. The electrical system employs Omron relays and Schneider contactors, components selected for reliability in continuous-duty agricultural environments

.

Safety integration includes light curtain protection, hydraulic safety locks, and emergency stop circuits. Optional configurations extend to movable workbenches facilitating loading operations, water-cooling radiators for high-temperature environments, and automated feeding systems for production line integration

.

Zhongyou maintains ISO9001 quality management certification and CE machinery safety compliance

. Pre-delivery inspection protocols encompass pressure testing at 110% rated capacity, dimensional verification of pressed samples, and continuous operational trials exceeding eight hours. The company has established export channels to over 20 countries, with packaging protocols including internal plastic moisture-proof sealing and plywood external containment for ocean freight

.

Delivery timelines typically range 30-45 days post-order confirmation, with technical documentation including foundation drawings, hydraulic schematics, and operation manuals provided in English or client-specified languages. Installation support encompasses on-site commissioning and operator training, with warranty coverage extending 12 months for mechanical components

.

Procurement decisions should align machine specifications with production objectives. Small-scale operations (under 500 blocks daily) achieve optimal economics with 315-ton systems, while commercial enterprises targeting export markets require 630-ton or 800-ton configurations with integrated packaging lines

. Zhongyou’s product tiering enables capacity-matched investment, with upgrade pathways accommodating business expansion without complete equipment replacement.

The company’s designation as “Animal licking salt block press machine group standard setting unit” by Chinese industry associations reflects its technical influence within the sector

. This standard-setting role informs continuous product development, with recent innovations including IoT-enabled production monitoring and rapid mold changeover systems reducing format transition times from four hours to 45 minutes.

For livestock operations and feed manufacturers evaluating mineral block production equipment, Zhongyou’s integrated manufacturing capabilities, established export infrastructure, and tiered product range present a technically grounded procurement option aligned with diverse operational scales and market objectives.
